Conservation Authorities and the Great Lakes
Conservation Authorities planned programs and activities help Ontario to protect the important resources within the Great Lakes and St. Lawrence River, and their watersheds. This area is rich with forests, wetlands, rivers, streams, aquifers, and plants and animals that supply us with water for drinking, manufacturing, agriculture, energy production, fishing, food processing and many other uses. We are also drawn to these waters for recreational activities such as swimming, boating, camping and picnicking.
Conservation Authorities supports Ontario's Great Lakes Strategy which recognizes important connections between the Great Lakes and the contributing watersheds. The strategy also supports the protection of Great Lakes ecosystems and their functions including surface and groundwater quality and quantity, habitat and species, and considerations for climate change.
Protecting the Great Lakes and St. Lawrence River, and their watersheds is everyone’s responsibility because what happens upstream can impact conditions downstream.
