Water in Ontario
Fresh, clean water is vital to our survival and quality of life.
Ontario is fortunate to have a large supply of fresh water. Our province includes more than 250,000 lakes, countless rivers and streams, and many sources of groundwater. They provide us with drinking water, waterpower and recreation opportunities. Our lakes, rivers and wetlands are home to fish, birds, animals and plants.
