Canada's freshwater quality in a global context – Water quality rankings of selected industrialized countries according to the 2010 Environmental Performance Index

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The water quality indicators measure water conditions for various locations across Canada. It combines measurements of a wide range of substances found in water samples. The indicator focuses on how suitable the water is for plants and animals; aquatic life is present in all water bodies, is sensitive to pollution, and reflects the overall health of aquatic ecosystems. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.
