3. Information gathering, objectives, guidelines and codes of practice

Part 3 of the Canadian Environmental Protection Act, 1999 (CEPA 1999) authorizes the Minister of the Environment to:

This part also authorizes the Minister of Health to:

Delivering environmental results depends, in part, on Environment Canada and Health Canada:

In Canada, air and water quality monitoring is carried out through partnerships among provincial, territorial and federal governments, municipalities, universities, air and water associations, environmental groups and volunteers.

The National Air Pollution Surveillance network is a joint federal, provincial, territorial and municipal network established in 1969. It is primarily an urban network, with nearly 300 air monitoring stations in 177 communities. In total, almost 840 instruments, including continuous analyzers, particulate monitors, and samplers, are used to provide air quality measurements of toxic substances such as polycyclic aromatic hydrocarbons and dioxins and furans, as well as heavy metals such as arsenic, lead and mercury. Over the years, the network has produced one of the largest and most geographically diverse databases of pollutants in Canada.

Data from the National Air Pollution Surveillance network is used in the Canada-wide Standards programs for assessing trends in both particulate matter and ozone. Ozone data is used by the Canadian Environmental Sustainability Indicators program for its air indicator, while the Canada-U.S. Agreement on Air Quality uses data from the National Air Pollution Surveillance network for discussions relating to transboundary pollution. In addition, a large number of requests for data are received each year from Environment Canada and Health Canada and by provincial, territorial and municipal governments for their various studies.

In 2005-06, the network was expanded to provide enhanced coverage of particulate matter with a median diameter of 2.5 microns in anticipation of the Canadian Environmental Sustainability Indicators program adding particulate matter with a median diameter of 2.5 microns to the air indicator for 2006 and subsequent years. Since no standard technique exists for measuring particulate matter with a median diameter of 2.5 microns, an intercomparative study was initiated to provide information on the differences between the common real-time measurement techniques and the conventional gravimetric techniques. To understand the composition of particulate matter with a median diameter of 2.5 microns, which varies considerably with location and season, a particulate matter with a median diameter of 2.5 microns speciation network was also established. By summer 2006, this network will have 12 sites in place. Samples taken at each site will be analyzed for organic and elemental carbon, ions and metals. The data will then be analyzed to ascertain the impact of local sources, both stationary and mobile, and long-range transport. As well, the data will be used to understand the various chemical processes that occur in the atmosphere.

Health Canada has collaborated with Environment Canada since 2002 to assure consistency between Health Canada's measurements of airborne metals in indoor environments and those of the National Air Pollution Surveillance network. Accomplishments in 2005-06 include interlaboratory and intermethod comparisons between the Environmental Health Sciences Bureau of Health Canada and Environment Canada's Environmental Technology Centre. A valuable outcome of this work was the improvements on protocols for the total extraction of metals from urban particles.

The Canadian Air and Precipitation Monitoring Network is a regional/remote monitoring network that has been measuring air quality since 1978. There are currently 30 measurement sites in Canada, located in rural areas representative of regional air quality. One site in the United States and another in Canada ensure the comparability of measurement methods between the Canadian and U.S. networks.

In 2005-06, the network continued to support air quality programs by:

Data have also been collected at selected sites on a wide range of other pollutants, including substances that were found to meet the criteria of section 64 of the Canadian Environmental Protection Act, 1999 (e.g. particulate sulphate, gaseous ammonia, nitrate, gaseous sulphur dioxide and nitric acid). Over 25,000 samples of all types were analyzed in 2005-06 in support of Canadian environmental research initiatives.

Under the North American Commission for Environmental Cooperation, Health Canada is leading a tri-national maternal blood contaminant study with the United States Centers for Disease Control and Prevention and the Mexican National Institute of Public Health. The protocol has been finalized and sampling is under way, after initial delays in enrolment due to ethics reviews at all the Canadian sites. When the results are available from all three national sampling programs, Health Canada has agreed to assemble the tri-national database and undertake the national comparisons. A tri-national report and scientific papers will be prepared based on the results of this study.

Northern Contaminants Program has continued its monitoring and assessment work by measuring levels and time trends of pollutants, including persistent organic pollutants, mercury and other metals, as well as new and emerging chemicals, in air, water, biota, country foods and human beings. Human health research on exposure to and effects of these contaminants is being funded by the Northern Contaminants Program and is under way in Arctic Canada. The Northern Contaminants Program is led by Indian and Northern Affairs Canada, but is managed by an interdepartmental (Health, Environment, Fisheries) and multi-sectoral (Aboriginal groups, territorial governments) management team.

In 2005-06 a special issue of the journal The Science of the Total Environment included an assessment of Arctic human health issues by 17 health scientists. Titled "Human Health Implications of Environmental Contaminants in Arctic Canada: A Review," the information it contains has been used by Canada to meet some of its reporting and monitoring requirements under international agreements such as the Stockholm Convention on Persistent Organic Pollutants and the United Nations Economic Commission for Europe's Convention on Long-range Transboundary Air Pollution.

The Northern Contaminants Program agreed in 2005-06 to undertake an update on the human health implications of Arctic environmental contaminants and this assessment will be released in 2008. This will provide input of Canadian data to the Arctic Monitoring and Assessment Programme.

The Canadian Northern Contaminants Program and the international Arctic Monitoring and Assessment Programme collect and publish data on the health impacts of the long-range transport of pollutants into the Arctic. Their findings show that bioaccumulation of some persistent organic pollutants in the traditional marine mammal diet of Inuit peoples can exceed human health guidelines for dietary intake. The Arctic Monitoring and Assessment Programme Human Health Assessment Group, co-led by Canada (Health Canada) and Denmark, has agreed to undertake a third contaminant assessment of the circumpolar Arctic, including special reference to mercury, as requested by the Arctic Monitoring and Assessment Programme Working Group and Arctic Council of Ministers; its release is scheduled for late 2008.

The Global Atmospheric Passive Sampling Study is a global network for monitoring chemicals in the environment using simple sampling devices that require no electricity. This two-year pilot study was initiated in December 2004 at more than 50 sites located on all seven continents. It is a collaborative effort managed by Environment Canada scientists working with a team of international researchers. The results of the study will contribute to Canada's obligations under the Stockholm Convention on Persistent Organic Pollutants under the United Nations Environment Programme, specifically Article 16 on Effectiveness Evaluation, and the United Nations Economic Commission for Europe's Persistent Organic Pollutants Protocol. As a result of the successful pilot study and the need for continued measurements of persistent organic pollutants in the air, Global Atmospheric Passive Sampling will be maintained over the next few years with an emphasis on filling data gaps for persistent organic pollutants, and capacity building and technology transfer with developing regions.

Environment Canada, in partnership with Statistics Canada, Health Canada, and the provinces and territories, began implementation of the national Freshwater Quality Indicator program under the Canadian Environmental Sustainability Indicators initiative. The program includes the expansion of the nationwide water quality monitoring network to support the data requirements of annual reporting on freshwater quality. A preliminary national freshwater indicator was reported on in the first Canadian Environmental Sustainability Indicators annual report, published in the fall of 2005. It integrates data from federal, provincial and territorial water quality monitoring networks.

Environment Canada completed a three-year, national-scale surveillance project to identify the presence and levels of priority pesticides in selected Canadian aquatic ecosystems. This project, which was funded by Environment Canada's Pesticide Science Fund, focused on vulnerable watersheds (e.g. sensitive aquatic habitats and drinking water sources). The results of this project provide direct decision-support to the Pest Management Regulatory Agency for pesticide re-evaluations and special reviews, assisting the Pest Management Regulatory Agency to measure the success of some of its risk-management efforts.

On December 14, 2004, the Prime Minister and Territorial First Ministers released a draft framework for the first-ever jointly developed Northern Strategy. The framework included a draft vision for the North, along with suggested principles to guide the development of the Strategy and set possible goals and objectives to realize the vision for the North, as laid out in the Northern Strategy Framework.

Several monitoring programs will support the strategy. In 2004-05, four air quality monitoring stations, through the National Air Pollutant Surveillance network, were deployed in the North to provide data in support of the Strategy's objectives. Yellowknife has two monitoring sites that are equipped to sample for ozone, sulphur dioxide, nitrogen oxides, carbon monoxide, particulate matter less than or equal to 2.5 and 10 microns, and total suspended solids. The other two stations are located in the Yukon and Nunavut. The Yukon station is set up to monitor for ozone, nitrogen oxides, carbon monoxide and particulate matter less than or equal to 2.5, whereas the Nunavut station, located in downtown Iqaluit, allows for the collection of coarse particulate matter. Nunavut has plans to include additional stations and the monitoring of fine particulate matter.

In addition, the Northwest Territories have made plans to expand the air monitoring network to address the proposed Mackenzie Gas Project (natural gas pipeline), diamond mines, diesel power generation, hospital biomedical waste incinerators, and overall community air quality.

The Ecological Monitoring and Assessment Network seeks to improve understanding of ecological change in Northern Canada by promoting coordination and communication of the results of long-term ecological monitoring. The network also contributes to the understanding of issues such as persistent organic pollutants and heavy metals, climate change, environmental predictions, and changes to fresh water. The data collected will be used to support the Northern Strategy and its goals.

Other monitoring programs that monitor the North include:

Ambient environment quality monitoring programs are carried out in Lakes Superior, Huron, Erie, and Ontario, as well as in the St. Clair/Detroit corridor and the Niagara and St. Lawrence rivers. Measurements of organic contaminants (including emerging chemicals) and trace metals are made in water, whole fish (top predators) and sediment to assess progress toward specific goals in environmental improvement, to identify problems and emerging issues, and to support planning and decision-making. While long-term trends indicate declining concentrations of most contaminants, some chemicals continue to exceed water and sediment quality guidelines, as well as guidelines for the protection of piscivorous wildlife; and fish consumption advisories continue throughout the Great Lakes. Reports on legacy pollutants, in-use pesticides (Kannan et al., 2006),1 including a series of reports highlighting the results of screening-level surveys of sediment quality in Great Lake tributaries (Burniston and Kraft, 2006a),2 (Burniston and Kraft 2006b);3 (Burniston, et al., 2006)4 and Lake St. Clair surface sediment contamination (Gewurtz, et al., 2006)5 have been completed.

In 2003, the Binational Executive Committee, which is co-chaired by the United States Environmental Protection Agency and Environment Canada, endorsed the Cooperative Monitoring Initiative to improve the coordination of monitoring in the Great Lakes. A five-year rotational cycle was adopted to focus on one lake per year, with Lake Ontario being the first (2003), followed by Lake Erie (2004), Lake Superior (2005-06) and Lake Huron (2007). During both 2005 and 2006, the focus was on Lake Superior. Cooperative Monitoring efforts included multi-media (atmospheric, water, sediment, fish and lower foodweb) measurements of critical pollutants, as well as atrazine and emerging chemicals; nearshore and offshore lower trophic level monitoring; screening of Canadian and U.S. tributaries for toxic contaminants; and a multi-agency intercomparison study for contaminants in fish. These efforts pulled together federal, state and provincial agencies in a unique way that allowed for building on existing programs.

Mean values of eight contaminants in Herring Gull eggs were calculated for 15 Great Lakes sites for the five-year period from 1998 to 2002. The sites were ranked according to the concentrations of seven compounds relative to fish flesh criteria for the protection of piscivorous wildlife and a single overall rank was calculated for each site. Eggs from Saginaw Bay, the St. Lawrence River and northern Lake Michigan ranked as the three most contaminated sites, and those from eastern Lake Superior, southern Lake Huron and eastern Lake Erie ranked as the three least contaminated sites (Weseloh, Pekarik, and de Solla, 2006).6

Mandated by Annex 15 of the Great Lakes Water Quality Agreement, the Integrated Atmospheric Deposition Network is a Canada-United States network that monitors concentrations of persistent, bioaccumulative and toxic pollutants in the air and in precipitation near the Great Lakes. In 2005-06, the network measured the concentrations of polychlorinated biphenyls, organochlorine pesticides, polycyclic aromatic hydrocarbons and trace metals in the atmosphere at stations located on the shores of all the Great Lakes. The results show that the lakes are still receptors of atmospheric deposits of toxic chemicals and that levels of banned compounds in air and precipitation are generally decreasing following the in-basin emission control of these substances. In addition, data indicate that future reductions in the levels of toxic chemicals in the water will be directly related to decreasing concentrations of these compounds in the atmosphere.

A report on contaminant loadings for the period 2001-04 indicates that polychlorinated biphenyls continue their trend of volatilizing - the process by which polychlorinated biphenyls in surface waters become airborn - out of the Great Lakes, emphasizing the link between lake water and atmospheric concentrations. Loadings of combustion and industrial by-products such as polycyclic aromatic hydrocarbons and trace metals have remained constant over time. Urban areas are important sources of atmospheric toxic pollutants, particularly polychlorinated biphenyls and polycyclic aromatic hydrocarbons, and the inclusion of urban data is critical to obtaining an accurate representation of the deposition of airborne toxic pollutants to the Great Lakes Basin.

Monitoring of physical, chemical and biological parameters in the St. Lawrence is ongoing. Data were collected on the quality of water and sediment, shore erosion, land-use patterns, changes in the composition of wetland plants, invasive plant species, and the benthic communities inhabiting Lake Saint-Pierre and analysed to report on the situation to the public. Monitoring of recreational usage of Lake Saint-Pierre was also begun thanks to the involvement of non-governmental organizations.

Six fact sheets were prepared for dissemination on the Internet and access to information on St. Lawrence wetlands and sediment geochemistry were made possible by the use of an interactive mapping application.

All the program partners also made a special effort to prepare the second edition of the public forum St. Lawrence Rendez-Vous 2006. The main objective of this triennial event is to make public the updated results of the environmental indicators of the State of the St. Lawrence Monitoring Program.

Scientific research is used to:

Environment Canada and Health Canada scientists published hundreds of articles, reports and papers during this reporting period. The following examples illustrate the types and range of research undertaken in 2005-06.

The Canadian Wildlife Service and the Science and Technology Branch (National Wildlife Research Centre, NWRC) have been investigating the exposure and health effects of legacy and new, emerging chemicals of concern on wildlife, particularly snapping turtles, mink and herring gulls. Results have been presented at a number of management and policy meetings for several Canadian Areas of Concern on the Great Lakes. In addition, results have either been published (e.g. mink: Environmental Monitoring and Assessment, 2006) or are in review (e.g. snapping turtles: Environmental Science and Technology).

Methodology

The avian, embryonic neuronal cell culture method that was developed in the laboratory at the National Wildlife Research Centre has been used as a preliminary screening tool for various suspected neurotoxins such as polybrominated diphenyl ethers and perfluorinated compounds.

Several analytical methods have been developed including the following.

Substance specific research

The following studies are an indication of the type of substance specific research conducted by Environment Canada scientists.

Understanding the effect of pollution on water and sediment quality

From April 1, 2005, to March 31, 2006, seven fish processing plants were sampled as part of an ongoing wastewater characterization study. The fish processing plants were located in the Atlantic Provinces of Nova Scotia, New Brunswick, and Newfoundland and Labrador. The characterizations included conventional chemical parameters as well as toxicity testing of the wastewater. Sediment samples taken in the vicinity of fish processing wastewater outfalls were also obtained in March. They were characterized by various physical-chemical parameters and toxicity testing to an amphipod species. The levels of toxicity in the effluents and adjacent sediments were found to range from negligible to high. The next step in this project is the start of a formal assessment of fish plant effluent nation-wide. The assessment process will take place over the next three years to determine the environmental risks associated with effluents from fish processing plants across Canada and possible mitigative measures.

A number of projects were undertaken to determine the sources of emerging contaminants such as organo-silicone compounds, polybrominated diphenyl ethers and other brominated flame retardants in the Canadian environment. Among them is an assessment of country foods, a study to determine levels of polybrominated diphenyl ethers and other brominated flame retardants in sewage sludge and soils at southern locations in Canada. Other studies will determine the limit for polybrominated diphenyl ethers in effluents from sewage treatment plants and biosolid substances found to be persistent, bioaccumulative and toxic under the Canadian Environmental Protection Act, 1999 and that meet the criteria for virtual elimination. These studies provide early estimates of the levels of these chemicals released from wastewater treatment plants.

Health Canada is conducting research on disinfection by-products and emerging contaminants in drinking water. This work includes the development of analytical methods for these substances and studies of their occurrence and stability in distribution systems. The methods targeted over 40 compounds, some of them included on the Canadian Environmental Protection Act, 1999 Priority Substances List. Selected samples collected in 2005-06 showed levels of N-nitrosodimethylamine below 2.5 ng/L. Current studies targeted other nitrosamines (nitrosodibutlyamine, nitrosodiethylamine, nitrosomorpholine, nitrosopiperidine and nitrosopyrrolidine), in addition to 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone or Mutagen X (MX), haloacetic acids, trihalomethanes, haloacetonitriles, haloketones, haloacetaldehydes, chloropicrin and cyanogen chloride.

Studies continued to evaluate the sources of fecal coliforms and waterborne pathogens in aquatic ecosystems, particularly the Great Lakes, and to develop methods for source tracking and detection of these microbial contaminants in water. This work resulted in publications on denaturing gradient gel electrophoresis, a method based on the difference of melting points of double-stranded deoxyribonucleic acid fragments. Work continued on the deoxyribonucleic acid microarray fingerprinting of microbial communities to determine batch-to-batch variation and shelf life of microbial biotechnology products subject to the Canadian Protection Environmental Act, 1999. This work led to the closure of polluted beaches in Hamilton Harbour and Toronto to swimmers.

Methodology

3.2.5.1 St. Lawrence Plan

Examples of research conducted in 2005-06 are presented hereunder.

Environmental chemistry

Urban effluents are considered one of the primary reasons for nuisance pollution and represent an important risk to the ecosystems. Urban effluents, by their volume and concentration, represent an important source of conventional and emergent contamination. Principal results include the modeling of the complexion of metal in the effluent matrix that controls the inherent toxicity and bioavailability of the contaminant, and the development of an automated method for quantifying certain antibiotic substances both in the effluents and in surface waters. The fate of certain antibiotic substances was documented, as was the level of elimination of pharmaceutical substances by new proposed test technologies that are being evaluated.

Ecotoxicology

Field studies conducted in the freshwater portion of the St. Lawrence River (Lac St-Pierre archipelago, rich in biodiversity) and in its estuarine portion (Saguenay Fjord) with caged and endemic bivalves as model species, have shown deleterious effects of contaminant mixtures on reproduction (hormonal effects triggering high levels of egg yolk protein, feminization and/or masculinization, and neuro-endocrine anomalies), on immune response (immuno-suppression), as well as on their general state of health (lipid peroxidation, genotoxicity, premature aging) owing to the presence of mixed and diffuse sources of pollution. In addition to field studies, real-time exposure to urban effluents confirmed the source of neuro-endocrine anomalies for fluvial ecosystems. Research continues to attempt to link chemical sources to the observed effects so that curative actions can be taken and determine whether the implementation of secondary treatment processes could mitigate these harmful effects.

New projects on the evaluation of nanoproducts using bioassays and biomarkers were initiated in 2006. These projects will address different modes of action of nanoproducts. The trophic chain toxicity of nanomaterials will be studied using microbiotests and biochemical indicators to determine their mode of action. Preliminary results indicate some environmental toxicity of several nanoproducts or an increase in the toxicity of other contaminants in water or substrates.

3.2.5.2 Great Lakes

Examples of the research conducted in the Great Lakes are given below.

Health Canada research scientists continued their activities aimed at understanding the toxic effects of mixtures of hormone-disrupting substances present in breast milk and human serum. Recent results suggest that a mixture of polychlorinated biphenyls, p,p'-dichlorodiphenyltrichloroethane and dichlorodiphenyldichloroethene changed the hepatic metabolism of estrogens, and that this could be a sensitive indicator of long-term effects (Desaulniers et al. 2005).36 Early exposure to a different mixture of polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans led to hepatic changes in deoxyribonucleic acid methylation and estrogen signalling (Desaulniers et al. 2005).37 None of the mixtures induced changes at the estimated dose received by humans. Ongoing experiments are aimed at understanding the contribution of additional chemicals to the toxicity of complex mixtures, with the intent of differentiating the magnitude of the risks that might be attributed in utero from the postnatal period of exposure.

Research funded by the Health Canada Genomics Research and Development Programme has shown that suppression of thyroid hormone causes permanent developmental changes in the expression of genes. This information is being used to identify biomarkers of thyroid suppression.

Examples of research conducted in 2005-06 are presented hereunder.

Reducing the health and safety impacts of environmental threats by using:

In 2005-06, a number of collaborative efforts were carried out by Health Canada to advance knowledge of the fate and effects of pharmaceutical and personal care products on the environment. This research included evaluating the persistence and mobility of chemical and microbial contaminants contained in biosolids applied to agricultural fields, the effects of selected anti-microbial agents on aquatic microbial community structure, diversity and function, and the occurrence of antibiotic-resistant aerobic bacteria in sediments at aquaculture sites in the Fundy Isles Region of southwest New Brunswick. The results obtained will be relevant to assessment of the potential risk of these compounds in the environment and contribute to the development of new environmental assessment regulations for substances in Food and Drugs Act products currently underway.

Currently, there is limited understanding of the ecological implications of pharmaceutical and personal care products. Pharmaceuticals and broad-spectrum antibiotics have been widely detected in the natural environment; they enter ecosystems in runoff and in the discharge of treated sewage effluent into aquatic water bodies.

Studies were undertaken to gain a better understanding of the effects of pharmaceutical compounds, present in treated sewage effluent, on the microbial ecology of the Wascana Creek/Qu'Appelle River system. Evaluations were made of in situ bacterial and algal production and biomass, microbial biodiversity and physiological state at sites downstream of the city of Regina's sewage treatment plant. Creek water was monitored (upstream and downstream from the sewage treatment plant) to investigate concentrations of pharmaceuticals and personal care products. Trimethoprim was present in the highest concentration (90 ng/L) at Site 2 (0.4 km downstream of the Regina sewage treatment plant), with concentrations gradually decreasing until the last sampling site located 104 km downstream of the sewage treatment plant, where none was detected.

In an additional study salicylic acid, ibuprofen, gemfibrozil, naproxen, triclosan, ketoprofen, diclofenac, and indomethacin were all detected in all the influent and most effluent samples taken from a wastewater treatment plant. Currently, there is very limited understanding of the ecological implications. Studies were also performed in rotating annular bioreactors to assess the impact of pharmaceuticals on river biofilms.

Even at only 10 ppb, pharmaceuticals appeared to exhibit both nutrient-like and toxic effects on the microbial communities in these aquatic systems.

A gas chromatography-tandem mass spectrometry method has been developed for the determination of selected acidic and neutral pharmaceutical products in sewage influent and roughly primary-treated effluent at the ng/L level. Results show that physical and chemical processes at wastewater treatment plants remove little of the studied pharmaceuticals. Pilot studies were conducted to test three different types of wastewater disinfection processes (ultraviolet radiation, performic acid, and ozonation) on the removal efficiency for those substances. Ozonation appears to be more effective in removing the detected substances in wastewaters than either ultraviolet radiation or performic acid treatments. New metabolites emerging from disinfection treatments, however, remain unknown.

More than 2,000 groundwater and surface-water samples provided by the Department of Defense, Environment Canada, the provinces and other agencies were analyzed. Sampling efforts addressed areas where perchlorate contamination was of potential concern: military installations, mining, sectors using sodium chlorate, firework displays and arid areas. Perchlorate was not detected at concentrations > 6 µg/L (Health Canada's proposed guideline) in drinking water, but it was observed to exceed this level in areas where specific point sources of perchlorate were identified. The evolving science on this issue continues to be monitored and the survey results will serve to add to our understanding of perchlorate as a contaminant in Canada.

There are numerous programs across the country that are intended to enable Environment Canada to demonstrate that pollution prevention practices can be achieved at work and in everyday lives. Examples of regional pollution prevention actions are listed in the following sections.

Whitehorse Community Challenge

The Whitehorse Community Challenge received funding from Environment Canada to focus on energy efficiency and waste reduction activities. Organizers conducted free waste assessments for local businesses and created a "Welcome to Whitehorse" package for new residents that included information on waste diversion programs, active transportation, and greenhouse gas reduction. The community also offered do-it-yourself workshops with free instructions and consultations on home renovations, EnergySTAR products, heating source options, and landscaping to increase home energy efficiency.

Town of Morden and Winkler

The Town of Morden and Winkler in Manitoba received funding from Environment Canada and the province of Manitoba's Climate Change Community Challenge initiative to develop environmentally sustainable capital projects and encourage citizens to take action to reduce greenhouse gas emissions. They worked with community councils to develop a strategic action plan to retrofit public facilities. The Town of Morden initiated a geothermal heat pump retrofit for the fire hall and retrofitted municipal buildings with energy efficient lighting and programmable thermostats. This initiative was successful in decreasing the amount of energy required to operate municipal structures and in raising awareness for such actions throughout the community.

The North

Through departmental programs like Weather Watchers (i.e. individual Canadians submit information on weather status and trends), the One-Tonne Challenge, and EcoAction program (projects to protect, rehabilitate or enhance the natural environment and build the capacity of communities to sustain these activities into the future), Environment Canada works directly with Northerners to encourage them to act on climate change and other environmental priorities. In addition to such efforts, Environment Canada has undertaken new relationships with local governments and Aboriginal organizations across the North to build understanding and action to address environmental issues.

The occurrence, trends and pathways of contaminants in the Arctic were discussed in a special issue of the journal The Science of the Total Environment, with an additional special issue dealing with contaminants in fish, wildlife and humans in this area.

Don Valley West Community Challenge

In Ontario, the Don Valley West Community Challenge worked with the local utility, Enbridge, to deliver the TAPS program (Take Action with Programs for Savings). This program targets homeowners to turn down their hotwater tanks, install aerators in faucets, pipe-wrap hot and cold water lines, replace showerheads with a low-flow model and install compact fluorescent lightbulbs. Through this program, 600 homes in the community were successfully retrofitted.

Business Air Quality Program Pilot

The goal of the Business Air Quality Program pilot is to motivate small and medium-sized enterprises in the industrial manufacturing sector to implement voluntary and beyond-compliance best practices, as a way to improve their environmental performance and economic competitiveness through material substitution and process improvements. The objective is to reduce key criteria air pollutants, including nitrogen oxides, sulphur dioxide, particulate matter and volatile organic compounds.

Delivered under the Canada-United States Border Air Quality Strategy, the Business Air Quality Program pilot focuses on reducing air emissions from industrial small and medium-sized enterprises in southwestern Ontario. In March 2006, an agreement was reached with the Ag Energy Co-operative to partner on their Demand Side Management Program. This involves conducting energy audits at selected greenhouse facilities in southwestern Ontario, in support of emissions reductions under the Border Air Quality Strategy. This program is supported by The Ontario Greenhouse Alliance which represents flower and vegetable growers, Ontario Ministry of Agriculture, Food and Rural Affairs, Hydro One, Enbridge, Union Gas, Ontario Power Authority and The Cecil Delworth Foundation. The Rural Economic Development Program of the Ontario Ministry of Agriculture, Food and Rural Affairs is also providing financial support.

Environment Canada contributed a front-end subsidy of 50% of pollution prevention audit costs, to a maximum of $5,000 per facility. The participating small and medium-sized enterprises are responsible for the remainder of the audit costs. This pilot is also being coordinated with Natural Resources Canada's existing Industrial Energy Audit Incentive to capture air quality co-benefits that are currently not being quantified. Over 20 facilities are participating in the program, which has now been extended to March 2007.

Burn It Smart

In Ontario, 18 Burn It Smart workshops were held to help professional contractors and the general public to identify ways to reduce the impacts of residential wood burning. An additional 10 workshops were held for First Nations communities in Ontario. The Burn It Smart campaign was presented at a number of public events, including the Cottage Life Show and International Plow Match, to reach and educate the local public outside the workshop format.

Retail partnerships were established with Home Depot and Home Hardware. Home Depot had Burn It Smart events at six of their locations in Ontario. The events were a great success, with customers continuing to ask for their return. Burn It Smart information was also provided at a national meeting for Home Hardware retailers from across the country.

The campaign also produced new educational material, including a DVD containing three videos on Environmental Protection Agency approved woodstoves, firewood preparation and woodstove operation. This DVD has been well received, with retailers offering it in their stores and the United States Environmental Protection Agency using it in their education campaigns.

Through ongoing collaboration with the United States Environmental Protection Agency under the Great Lakes Binational Toxics Strategy, Burn It Smart workshops were provided to local citizens in border towns in the states of New York, Wisconsin and Michigan, and also to Native Americans.

A number of research projects were undertaken in conjunction with the Puget Sound Clean Air Agency, the Hearth, Patio and Barbeque Association in the United States, and the United States Environmental Protection Agency to characterize emissions from wax firelogs and to determine emission factor verifications for conventional wood stoves.

The Toronto Region Sustainability Program

This Greater Toronto Area-based program is aimed at advancing the environmental performance of small and medium-sized enterprises in the manufacturing sector in the areas of pollution prevention and sustainable development. It addresses reductions in toxic substances listed in both the Canada-Ontario Agreement on the Great Lakes and the Great Lakes Binational Toxics Strategy.

Specific objectives include encouraging businesses to take action to reduce smog precursors, reduce or eliminate the use of toxics, and move to zero generation of toxic wastes. The program is a collaborative, multi-stakeholder effort, in partnership with the Toronto and Region Conservation Authority, and local and provincial governments. Small and medium-sized enterprises have seen a real value in the Toronto Region Sustainability Program, where all three levels of government have identified their priorities for action. For small and medium-sized enterprises, pollution prevention opportunities have brought significant returns on investment, cost savings, reduced risk of non-compliance that could be followed by enforcement actions, and better marketing opportunities.

In the first five years of the program, 44 of the 56 participating facilities have completed pollution prevention assessments, which represent the following identified annual pollution prevention results and savings:

Toronto Region Sustainability Program Annual Pollution Prevention Reductions and Savings

Volatile organic compounds (VOCs): 618 tonnes
Metals: 2 200 kilograms
Hazardous wastes: 1 394 tonnes
Toxic substances: 32 000 kilograms
Water: 327 478 tonnes
Greenhouse gases (GHGs): 1 673 tonnes
Particulate matter (PM < 10): 15.4 tonnes
Generic waste diversion (to recycling): 49 512 tonnes
Mercury waste diversion (to recycling): 5 044 grams
Average cost savings (per SME): > $70,000

EcoSchools: Resources for Schools

Ontario EcoSchools is a voluntary environmental education program that addresses both how the schools are run and what students learn. It has been designed collaboratively by school boards for school boards, with input from federal, provincial and municipal governments, to incorporate environmental education and environmentally responsible action into the school setting. The program aims to influence young people during a formative period of life and to have an exponential impact as children take a culture of conservation home with them.

Comprehensive guides have been developed to reduce energy use, minimize waste and design environmentally friendly school grounds. In addition, Ontario curriculum expectations that relate to climate change have been identified and elementary and secondary teaching resources have been developed for grades 1 to 12. The program focus is unique in that no other environmental education program actively involves both curriculum and facilities departments.

In 2005-06, 108 schools in six school boards were in various stages of implementing the EcoSchools program. Measurable successes include that on average, certified EcoSchools use 12% less electricity and 7% less natural gas than comparable non-certified EcoSchools (Toronto District School Board Energy Management Program Review, 2006).38

The program is designed to be replicated across all Ontario boards, and has the potential to be exported to other provinces and/or territories with appropriate curriculum modifications.

Through a cooperative partnership, the Canadian Centre for Pollution Prevention, Environment Canada and the Ontario Snow Resorts Association have been actively promoting environmental best practices to the Ontario Snow Resorts Association membership since 2003, through the creation of the Ontario Snow Resorts Association Environmental Best Practices Task force. This task force serves as a forum on issues related to pollution prevention, where ski resort operators can exchange information on best practices and work collaboratively with one another and with other partners to prevent pollution locally and regionally. The task force has developed an action plan that reflects the environmental priorities of ski resorts across Ontario whose scope encompasses the four-season reality of ski resort operations. The Blue Mountain and Osler Bluff ski resorts have been leaders in the industry, demonstrating that the recommendations in the handbook are realistic and achievable for both large and small facilities. They are both realizing reductions in energy consumption, solid waste, maintenance and operating expenses and are implementing green procurement in all areas of their facilities.

CleanMarine Eco-Rating Program

The CleanMarine Eco-Rating Program is an environmental best management practices initiative to assist marina operators and managers become more sustainable by implementing initiatives and policies designed to protect the environment. It was developed by the CleanMarine Partnership in 1997.

The CleanMarine program is led by the Ontario Marine Operators Association (OMOA: www.omoa.com) with input and support from the CleanMarine Partnership, which includes representatives from Environment Canada, Ontario Ministry of Environment, Ontario Sailing Association, Canadian Power and Sail Squadron, Canadian Marine Manufacturers Association, Ontario Boating Forum, Federation of Ontario Cottager Associations, Ontario Federation of Anglers and Hunters, and TerraChoice Environmental Marketing.

When the partnership was formed, information was compiled and developed into a resource tool that marina managers could use to assist them in protecting the environment and better managing their businesses. An audit is conducted by a third party to verify the initiatives implemented. The audit report provides the marinas with the information they require to help them improve their operations and it acknowledges the initiatives that they performed well. Re-audits are conducted every four years to encourage continuous improvement and ensure marinas continue to operate at the rating level initially awarded. As of March 2006, 248 marinas throughout Ontario had been audited.

Marina owners and managers have improved their business practices, reduced their impact on water resources, increased energy efficiency, managed natural habitats better and participated in community environmental projects, reduced solid waste and associated costs, reduced use of toxic substances, decreased risks of an environmental emergency, increased recycling of waste and prevented pollution. In 2005, over 1,000 tonnes of plastic shrink wrap was collected from participating marinas in Ontario and recycled instead of being landfilled.

Greening Retail

The goal of the Greening Retail program is to provide retailers with specific tools, strategies, and programs to improve their energy efficiency and environmental performance, and to play a major part in the transformation of society towards improving the environment. The project will demonstrate to retailers that undertaking these initiatives can enhance their bottom line and thus makes good business sense. All stakeholders associated with the retail industry will be engaged, starting with manufacturers and distributors, then to the retail developer or property manager, and ending with the consumer.

Identifying the Greening Retail opportunity for Canadian retailers is phase 1 of a three-part project that was initiated and completed in 2005-06. Research conducted in phase 1 confirmed the initial premise of Greening Retail: that retailers can profit from the implementation of good environmental practices and that leading retailers are embracing them. However, the research also indicated that the adoption of best practices is not yet pervasive in the sector. Discussions with leading retailers indicated that there is a need to support retailers with industry guidelines and detailed information to assist in the adoption of best practices in environmental management. Canadian retailers employ 12% of the Canadian workforce, generate $368 billion in annual sales and are primarily small or medium-sized enterprises. In 2002, retail facilities and their suppliers were responsible for 39 megatonnes of greenhouse gas emissions.

Centre québécois d'actions sur les changements climatiques

In the fall of 2005, the Quebec Public and Education Outreach Hub launched the Cocktail Transport campaign to promote sustainable transportation. This province-wide initiative encouraged people to opt for alternate modes of transportation and to carpool to work. Baseline and follow-up research indicated that two million people were reached through various marketing channels: Web site, radio, newspapers, posters, bus panels and roadside advertising. Incentives such as free bicycles and free transit passes were used to encourage participation in the campaign.

EnviroclubOM

EnviroclubOM is a Quebec organization that encourages small and medium-sized enterprises in the manufacturing sector to voluntarily reduce harmful emissions and lessen their dependency on natural resources while increasing their competitiveness. From the start of the program (2000) to March 2006, 14 Enviroclubs involving 168 small and medium-sized enterprises had been established. This resulted in $11.7 million invested in environmental projects, of which $2.9 million came from the federal government and $8.8 million from the private sector. The average payback period for these projects was one year and the total recurrent annual savings are estimated at $10.6 million. On the environmental front, these pollution prevention projects yielded net savings of 165,000 gigajoules/year, equivalent to 27,000 barrels of oil, a reduction of 800 tonnes of toxic substances, a decrease of 17,000 tonnes of wastes, and a reduction of 29,000 tonnes of carbon dioxide equivalent - comparable to the annual emissions of 6,200 cars. Added to the economic and environmental benefits generated by the Enviroclub program were the social ones: Enviroclub members become acquainted with pollution prevention concepts via the four days of mandatory training for all participating small and medium-sized enterprises.

Along with the Enviroclub program, the Quebec Environmental Protection Activities Branch promotes innovative technological solutions to improve environmental performance. There are currently 38 ongoing environmental technology projects in Quebec, while 21 have been completed. These projects have been in the areas of atmospheric emissions, climate change, wastes, toxics, wastewater, soil and groundwater decontamination, and energy. The immediate impacts of these technologies were in reduced atmospheric emissions, reduced water use, reduced water pollution, rehabilitation of brownfields, reduced material consumption, reduction and reclamation of wastes, reduced energy consumption, and reduction and disposal of toxic substances and hazardous wastes. These 59 projects totalled $56 million in investments, of which $18 million came from a variety of federal programs from several departments and agencies (National Research Council of Canada, Canada Economic Development for Quebec Regions, Industry Canada, Natural Resources Canada). The remaining $38 million in investment came from the private sector.

Residential wood heating

The air quality station, in operation since 1998 in a Montréal residential neighborhood impacted by wood heating, has allowed linking its use to a reduction in air quality. In January 2006, a new station was added to the National Air Pollution Surveillance Network in a residential area near Québec that is also impacted by residential wood heating. This second station should allow confirmation of the trend.

Initial data analyses of the new data are planned for 2007-08.

A Model Municipal By-Law to regulate wood heating appliances has been made available to municipalities in June 2006. The model by-law is a tool box to be used by a municipality wishing to develop and put in place a municipal by-law to regulate wood heating appliances. It is intended to be used by municipalities that experience air quality problems because of residential wood combustion.

A Bright Idea: Prince Edward Island, Climate Change Hub

A Bright Idea is an energy-saving campaign that ran in the winter of 2006 to educate homeowners about energy efficiency and climate change. Across Prince Edward Island, 94 homeowners were selected to have their homes retrofitted with up to 20 compact fluorescent lightbulbs. Pre- and post-campaign measurements conducted by Maritime Electric demonstrated that once the 1,730 compact fluorescent lightbulbs were installed, a total of 820,000 kilowatts were saved, amounting to an annual reduction of 61 tonnes of greenhouse gases. For homeowners, this resulted in a total annual savings of $8,200.

Pursuant to subsection 54(1) of the Canadian Environmental Protection Act, 1999, the Minister of the Environment shall issue environmental quality objectives, environmental quality guidelines, release guidelines, and codes of practice. These instruments shall relate to:

Pursuant to subsection 55(1) of the act, the Minister of Health shall issue objectives, guidelines, and codes of practice with respect to the elements of the environment that may affect the life and health of the people of Canada.

Environmental Quality Guidelines specify recommendations in quantitative or qualitative terms to support and maintain particular uses of the environment, such as protection of aquatic life, and land uses, including agricultural, industrial, commercial, and residential/parkland. Environmental Quality Guidelines are used to help interpret monitoring data and assess contaminated sites and are an integral part of the Canadian Environmental Sustainability Indicators by providing a means of consistent comparison.

In 2005-06, six Canadian Environmental Quality Guidelines, developed under the Canadian Council of Ministers of the Environment, were finalized. Also completed were revisions to the Protocol for the derivation of Soil Quality Guidelines for the protection of environmental and human health. Thirteen other Canadian Environmental Quality Guidelines were under development (see Table 1). Revisions were ongoing to the protocol used to develop Canadian Water Quality Guidelines for the protection of aquatic life and to the Sediment Quality Index, a communication tool for the management of contaminated sediment that uses a suite of Canadian Sediment Quality Guidelines.

During this reporting period, Environment Canada also provided six training sessions on the derivation and implementation of Canadian Water Quality Guidelines for the protection of aquatic life to government, industry and academia.

Drinking water quality guidelines are established by the Federal-Provincial-Territorial Committee on Drinking Water and published by the Minister of Health. They establish maximum acceptable concentrations of contaminants in drinking water.

In 2005-06, Health Canada continued to work in collaboration with the Federal-Provincial-Territorial Committee on Drinking Water to develop the Guidelines for Canadian Drinking Water Quality.

State of the environment reports and environmental indicators provide Canadians with information and knowledge about current environmental issues and foster the use of science and data in policy- and decision-making. Indicators, reports, data and tools are housed at or referenced through Environment Canada's State of the Environment Web site. This site also includes resources for reporting and indicator practitioners.

There is a growing need to develop tools to improve our ability to recognize environmental change. One such need centres on improving our understanding of food web structure and how food webs may change through time. Food web structure is important in determining the flow of energy, nutrients and contaminants through ecosystems. By measuring stable isotopes and fatty acids in archived Herring Gull eggs, we found that gull diets change over time. These changes reflected alterations in the Great Lakes that reduced prey fish availability. Dietary changes in fish-eating birds are important in terms of affecting diet quality and exposure to contaminants.39

Environment Canada collaborated with federal departments and agencies, other levels of government, and stakeholders to develop environmental indicators in support of decision-making on priority environmental issues, policies and actions.

Environment Canada, together with its partners Statistics Canada and Health Canada, completed the first annual report on the Canadian Environmental Sustainability Indicators, published in December 2005. This initiative is in response to recommendations of the National Round Table on Environment and Economy to focus on national indicators on air quality, water quality and greenhouse gas emissions, and is available online at two Web sites:

Measuring Sustainability: Canadian Environmental Sustainability Indicators

or

Statistics Canada

Environment Canada continued to work in collaboration with federal partners to develop, enhance and update environmental indicators (last reported on in 2003). These are a comprehensive set of indicators covering drivers and pressures and the state and quality of Canada's environment; they are a source of integrated data and science-based information to foster understanding and support decision-making on environmental sustainability.

During 2005-06, Environment Canada also contributed to the advancement and completion of state of the environment reports and the development of environmental indicators for several ecosystems in Canada.

Progress was made towards continued, periodic reporting on Environment Canada's ecosystem initiatives, as presented below.

Environment Canada co-chaired, with the United States Environmental Protection Agency, a multi-agency, multi-disciplinary team on the development and reporting of a suite of nine ecosystem indicators aimed at better understanding key ecosystem stresses and responses in the Georgia Basin-Puget Sound transboundary region. These indicators are: toxics in Harbour Seals; river, stream and lake quality; marine water quality; air quality; shellfish; marine species at risk; population health; urbanization and forest change; and solid waste and recycling. The Georgia Basin-Puget Sound Ecosystem Indicators Report increases the depth and breadth of ecosystem indicators reported in 2002 and is tailored to the information needs of the public and decision-makers, based on feedback received on the 2002 report.

EPA Region 10 (Pacific Northwest)

In partnership with the United States Environmental Protection Agency, Environment Canada released the State of the Great Lakes 2005 report. The sixth in a series of biennial reports beginning in 1995, this report provides an assessment of Great Lakes Basin ecosystem components using a suite of ecosystem health indicators.

The Northern Ecosystem Initiative has made progress towards the preparation of an indicators report for the Canadian North. A synthesis report including an initial suite of northern indicators drawing upon local, traditional and scientific knowledge and methods from across the Canadian North was drafted, in a collective effort to provide the latest understanding of the status and important trends in Northern ecosystems.

A survey of ecological monitoring activities within the Atlantic Coastal Action Program was conducted from February through April 2005. The survey compiled information on monitoring programs, data dissemination and management, as well as the effectiveness of data delivery and its impacts on policy and decision-making. One of the recommendations to emerge from this initiative was the development of a State of the Atlantic Coastal Action Program Environment report.

Environment Canada, along with a number of other partners, including the Department of Fisheries and Oceans, the provincial government and universities, contributed to a comprehensive report on the terrestrial and marine environments of the British Columbia coast. The work entailed the development of a largely new suite of indicators from those used in previous State of the Environment reports and the identification of data gaps for improved State of the Environment reporting. The indicators provided a synthesis of balanced peer-reviewed scientific information on six aspects of the coastal environment: ecosystem protection, industrial contaminants, fisheries, biodiversity, population and economic activity, and climate change. This integrated report establishes a baseline for environmental conditions and pressures for future comparisons.

The National Pollutant Release Inventory provides Canadians with access to information on the releases and transfers of key pollutants from industrial facilities located in their communities. The National Pollutant Release Inventory is the only national, legislated, publicly accessible inventory of its kind in Canada and it is an important consideration in managing risks to the environment and human health. Public access to the National Pollutant Release Inventory motivates industry to prevent and reduce pollutant releases and helps the Government of Canada track progress in pollution prevention, evaluate releases and transfers of substances of concern, identify and take action on environmental priorities, and implement appropriate policy initiatives and risk-management measures.

The National Pollutant Release Inventory tracks releases to air, water and land, quantities sent for disposal and recycling, and pollution prevention activities. For 2004 reporting, it included 323 pollutants, including toxic substances like mercury, dioxins and furans, hexachlorobenzene and polycyclic aromatic hydrocarbons, and air pollutants such as sulphur dioxide, particulate matter and nitrogen that contribute to smog and acid rain.

During 2005-06, almost 8,500 facilities reported to the National Pollutant Release Inventory on their releases and transfers of National Pollutant Release Inventory pollutants for the 2004 reporting year. The information they reported was made publicly available through the National Pollutant Release Inventory Web site and other means.

Recent changes, including the addition of reporting on air pollutants and the removal of the exemption on upstream oil and gas facilities, mean that National Pollutant Release Inventory is providing a more accurate and comprehensive picture of pollutants released to the environment from Canadian facilities.

Data for the 2004 reporting year were collected for the first time through the One Window to National Environmental Reporting System, which was launched in March 2005. The One Window to National Environmental Reporting System is a secure online reporting tool being used by Environment Canada, provincial and municipal governments, and private-sector organizations to collect environmental data from industry. Over time, One Window to National Environmental Reporting System will be able to consolidate many environmental reporting requirements into a single, integrated, online reporting platform, increasing the efficiency of reporting for both governments and industry while increasing the quality of reported data, the timeliness of their collection and publication, and their usefulness for environmental decision-making by governments, industry and the public alike.

Comprehensive emission inventories are compiled by Environment Canada for key air pollutants that contribute to environmental effects such as smog, acid rain and poor visibility. These inventories are used to track the progress of current emission-reduction strategies for various pollution sources, including industrial activities, residential fuel combustion, transportation vehicles, forest fires and road dust. In addition, they are used to identify priorities for future pollution prevention actions and to support the negotiation and implementation of domestic environmental programs and international agreements.

The Greenhouse Gas Emissions Reporting program was established by the Minister under the authority of subsection 46(1) of Canadian Environmental Protection Act, 1999, and announced through the publication of the Canada Gazette notice in March 2004. The collection of greenhouse gas emissions was continued with the Canada Gazette notice published in March 2005.

The greenhouse gas reporting program has four main objectives: to supply information to the national greenhouse gas inventory, to support regulatory development, to inform the public by publishing facility-level data, and to support provincial/territorial emissions information requirements. The program focuses on a limited number of emitters and basic reporting requirements, and lays the foundation for the development of a harmonized and efficient domestic reporting system for greenhouse gas emissions. Facilities that emit 100,000 tonnes of carbon dioxide equivalent (100 kt CO2 eq) or more annually are required to submit their greenhouse gas emission information to Statistics Canada by June 1 of each year. The reporting facilities include major industrial facilities that produce electricity, heat or steam using fossil fuels, certain power generation facilities, as well as integrated steel mills, facilities involved in smelting and refining metals, petroleum refineries, and chemical producers.

In June 2005, a total of 326 greenhouse gas reports were submitted, with the majority of reporting facilities being located in Alberta, Ontario and Quebec (71%). The total greenhouse gas emissions for 2004 from all reporting facilities presented just over one-third (37%) of Canada's total greenhouse gas emissions as published in the National Inventory Report, 1990-2004: Greenhouse Gas Sources and Sinks in Canada.

The data is published on the greenhouse gas program Web site.

Other actions taken by the program in 2005-06 include:

As a signatory to the United Nations Framework Convention on Climate Change, Canada is obliged to submit an inventory of its greenhouse gas emissions on an annual basis. Using an internationally approved format, the inventory monitors six gases: carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, perfluorocarbons and hydrofluorocarbons, and provides an analysis of the factors underlying the trends in emissions since 1990. Emissions and removals are grouped into six sectors: energy; industrial processes; solvent and other product use; agriculture; land use, land-use change and forestry; and waste.

Canada's Greenhouse Gas Inventory, 1990-2003 was submitted to the United Nations Framework Convention on Climate Change in April 2005 and represents Canada's eleventh National Inventory Report. The publication of the National Inventory Report allows Canada to track its progress in meeting its emissions reduction goals. The national greenhouse gas inventory also serves as the basis of the greenhouse gas indicator, as recommended by the National Round Table on the Environment and the Economy.
