Our Science

Environment and Climate Change Canada is a science-based department, and we provide the science and technology information needed so that Canadians can make informed decisions about the environment. In addition, Environment and Climate Change Canada’s science and technology work helps us to protect and conserve our air, water, wildlife and spaces. 

The majority of our budget and more than half of our workforce is dedicated to science and technology. Science, the foundation for our policy choices and the basis of our reputation with stakeholders and the international community, is key to our success. Environment and Climate Change Canada is an environmental science research leader, and conducts and publishes 80 per cent of our research in collaboration with external researchers. 

We use our research to track and manage wildlife populations, to improve understanding of ecosystems and support their recovery, to assess environmental risk, to issue weather and climate forecasts and warnings, and to support policy and legislative action.

To maintain our scientific capacity and offer our services, we operate 15 research institutes and labs, seven storm prediction centres, and 32 water survey offices. We also maintain extensive air, climate, and water monitoring networks made up of 800 staffed and automatic weather stations, 850 climate observing stations with twice daily observations by volunteers, and approximately 2900 hydrometric water observing stations across Canada. Our infrastructure includes radar and one of Canada's largest supercomputers.

Our Research

Environment and Climate Change Canada carries out research activities in a variety of fields including the following:

Climate Change Research

Our climate change research focuses on climate change and variability in Canada, the causes and the impacts.  Our approach includes: field and laboratory research aimed at understanding climate processes; monitoring atmospheric greenhouse gases to track and understand changes; and developing and applying of climate models to make projections of future change. Our scientific results provide the basis for adaptation and mitigation actions, for climate policy and development, and for climate-related services and products for Canadians.

Meteorological and Weather Research

Environment and Climate Change Canada maintains a meteorological research and development capacity that provides the department with the research necessary to improve weather and environmental prediction. The meteorological research and development program is the scientific foundation on which the weather and environmental prediction programs of Environment and Climate Change Canada are built. This research leads to Canadians receiving better advanced warning of severe weather events, and helps everyone protect themselves, their families and their property from harm.

Air Quality Research

Our science and research helps us to protect Canada's air quality. We study and measure air pollutants that can alter the atmosphere and affect human health, including acid rain, persistent organic pollutants, ground-level ozone, particulate matter, mercury, and substances that deplete the ozone layer. Our research is based on an integrated and multidisciplinary approach, which includes the study of the science of air issues, from the source of pollutants, and their transportation and interactions in the atmosphere, to the impacts on health and the environment.

Our air quality science and research supports the development of regulations, guidelines and policies as well as addressing Canada's international obligations. Our work also helps to keep Canadians informed about changes in air quality and the potential impacts on their health, by providing the science needed for the Environment and Climate Change Canada's daily forecasts of air quality and UV.


Water research includes research into water quantity and water quality. ECCC's thousands of water observing stations across Canada monitor water bodies for changes in water levels and for pollutants, such as toxic substances generated by industrial, agricultural and domestic uses.

This research is used to set Canada-wide standards for substances including mercury, petroleum hydrocarbons, dioxins and furans.


Because Canada has such a significant share of the earth's natural ecosystems—25 per cent of wetland ecosystems, 15 per cent of forests and 16 per cent of Arctic ecosystems—Environment and Climate Change Canada plays an important role as environmental steward.

Our nature research, which supports activities to preserve biodiversity and natural areas in Canada, is used to

  • develop recovery plans for species;
  • identify and conserve or restore ecologically important areas;
  • monitor migratory bird populations; and
  • track ecosystem health.

Our Enforcement Activities

Environment and Climate Change Canada’s Enforcement Branch is responsible for Canada's environmental and wildlife legislation. The Branch also participates in the development and administration of several other acts, as well as advises various federal agencies on other pieces of legislation.

Our enforcement activities relate to areas including the manufacture and use of toxic substances, import and export of hazardous wastes and materials, migratory birds, endangered species, and the protection of domestic water and water shared internationally. Our enforcement officers work with industries, businesses, farmers, provinces, municipalities, customs officials, hunters, the U.S. Environmental Protection Agency, Fisheries and Oceans Canada, and the Royal Canadian Mounted Police. They also testify in court, work undercover on smuggling operations, and conduct field inspections, investigations and intelligence activities.

Our Environmental Promotion Activities

To protect, conserve and enhance the environment, we help shape how Canadians think about the environment. We are doing this by sharing knowledge, developing and supporting partnerships, and establishing economic incentives to support sound environmental decisions.

Compiling our research into information tools such as the Canadian Bird Trends database, Hinterland's Who's Who, the National Pollutant Release Inventory, emission forecasts and trends, and engineering climatology products and services helps us increase awareness, show trends, and build capacity for environmental best practices.

Our Key Partners

We cannot tackle environmental issues alone. Partnerships are a fundamental way of doing business at Environment and Climate Change Canada.

Our key partners include:


Canadians are becoming increasingly involved in assessing the state of their environment and bringing about change. Programs such as Plant Watch and Frog Watch, launched by the Environmental Monitoring and Assessment Network with the support of local communities, help assess the state of Canada's environment.

Non-governmental Groups

Non-governmental organizations across the country–-at the community, regional and national level–-are actively carrying out projects related to clean air, nature, clean water, and climate change. These organizations are dedicated to making a positive impact on the environment, and play an important role in many of ECCC's public engagement activities. For example, with ECCC’s support, community groups across Canada have taken action, improving their local environment with positive and sustainable results.

Research Facilities

ECCC has partnerships with other research facilities; federal, provincial and territorial agencies; and universities to work on specific projects. These partnerships allow researchers to share expertise, pool resources and equipment, and avoid duplicating efforts.

Other Federal Departments

Environment and Climate Change Canada works with the other federal departments that deal with natural resources. The five natural resource departments—Agriculture and Agri-Food Canada, Fisheries and Oceans Canada, Health Canada, Natural Resources Canada, and Environment and Climate Change Canada—collaborate on research, share success stories, and disseminate information. This helps Canadians understand sustainable development issues and equips them to make and support informed decisions about sustainable development and the environment.

Provincial and Territorial Governments

The Government of Canada shares jurisdiction over environmental matters with the provinces and territories. ECCC works with provincial and territorial governments to develop policies and programs, undertake research, share success stories, and provide information on environmental issues of national and regional importance.  

These relationships are fostered through bilateral agreements as well as through the Canadian Council of Ministers of the Environment and other multilateral fora on specific issues such as domestic and international climate change, wildlife, species at risk and ecological areas, water, and environmental protection.

Aboriginal Peoples

ECCC works with the governments, communities, and organizations of the Aboriginal Peoples of Canada-–First Nations, Métis and Inuit-–to advance the Department’s programs and priorities, and to support Aboriginal environmental stewardship and objectives. This includes partnerships for the implementation of environmental legislation and programs, such as the Species at Risk Act.

Private Sector Organizations

Our partnerships with the private sector include work with industries such as the textile, dry-cleaning, pulp and paper, and wood preservatives industries to ensure compliance with environmental regulations and facilitate the adoption of pollution prevention measures.

International Organizations

Environment and Climate Change Canada is involved in at least seven United Nations organizations, including the United Nations Environment Programme, the World Meteorological Organization, and the Commission on Sustainable Development.

ECCC also participates in other international organizations such as the Arctic Council, the G-8, and the Inter-American Institute for Global Change, and has signed several bilateral agreements with individual countries.

The Beginning

Environment and Climate Change Canada was created on June 11, 1971, from elements of the Government of Canada such as the Meteorological Service of Canada (established in 1871) and the Canadian Wildlife Service (established in 1947).

The Department of Environment began operation with five services:

  • Atmospheric Environment Service
  • Environmental Protection Service
  • Fisheries Service
  • Land, Forest and Wildlife Service
  • Water Management Service

The architects of the early Department of Environment envisioned an organization that would act as ecosystem manager, incorporate ecological concerns into decision making, and be built on concepts now known as ecosystem-based management.

The 1970s saw improvements to the Atmospheric Environment Service's Weather Service, with bilingual forecasts initiated in Ontario, Quebec, and the Atlantic provinces, and with wind chill forecasts in Saskatchewan. In addition to this, the Weatheradio system was established, and the Canadian Climate Centre was created.

In 1979, organizational changes led to the Fisheries Service leaving the Department of Environment to form the Department of Fisheries and Oceans.

In the 1980s, Canada hosted the first International Conference on Acid Rain, and the Department of Environment launched the first of what would be a series of ecosystem initiatives with the Great Lakes Action Plan. The Action Plan opened the doors to a new way of doing business for the department. Using an integrated ecosystem approach incorporating water, air, wildlife, habitat, and pollution in the Great Lakes Basin, the department began to act as a catalyst, seeking collaboration among all interested parties. The launch of the Action Plan was the beginning of the Great Lakes clean-up and of our ecosystem approach, which is still the foundation of our work today.

In 2015, the Department become known as Environment and Climate Change Canada.

Continuing to Evolve

As a department, we continue to evolve in response to the needs of our clients and partners. From our initial mandate in 1970 to protect the biosphere, we moved to an integrated ecosystem approach in the 1980s and included the concept of sustainable development in Canada's Green Plan in the 1990s.

Today, Environment and Climate Change Canada continues to balance the need to protect the environment while growing the economy with regulatory frameworks to address air emissions, greenhouse gases, wastewater, and chemicals. Integrating environmental considerations into decision-making processes for projects as varied as mining and construction to the 2010 Olympic Winter Games is a natural demonstration of commitment to a foundation of sustainable development.

Our Report on Public Service Renewal Results

ECCC is a proud participant in Blueprint 2020, an initiative which was put forth by successive Clerks of the Privy Council in an effort to renew and improve the public service.  In 2016 the Clerk of the Privy Council asked all departments across government to create a report on public service renewal results.  We encourage all Canadians to read and view our Report on Public Service Renewal Results.
