Environment Canada


At Environment Canada our business is protecting the environment, conserving the country's natural heritage and providing weather and environmental predictions to keep Canadians informed and safe.

The Department has a strong comprehensive approach to ensure clean water for all Canadians. Our plan includes investments in monitoring, science and clean-up of problem areas, as well as building partnerships to protect our fresh water. Water research includes research into water quantity and water quality.


In Canada, the responsibility for safe drinking water is shared between the provincial, territorial, federal and municipal governments. The day-to-day responsibility generally rests with the provinces and territories, while municipalities usually oversee the day to day treatment operations.

Environment Canada's National Water Research Institute generates the scientific knowledge needed to sustain Canada’s water resources and freshwater ecosystems. The guidelines for drinking water quality are developed by Health Canada.
