Local Freshwater Quality in Canada

Freshwater quality was rated at 328 monitoring stations across Canada to evaluate if chemicals in water and physical properties were at levels that could harm aquatic plants and animals for the 2008 to 2010 period. Core stations were chosen based on their ability to represent key human pressures on water in Canada’s most populated drainage regions. Local stations are included to provide more local information.

How this indicator was calculated

Note: Freshwater quality was assessed using the Canadian Council of Ministers of the Environment’s Water Quality Index. Care must be taken when comparing regions, because different parameters and guidelines are used to assess water quality across provinces and territories.
Source: Data were assembled by Environment Canada from existing federal, provincial, territorial and joint water quality monitoring programs.
