Water in Ontario
Ontario is fortunate to have a large supply of freshwater. The province boasts more than 250,000 lakes and countless rivers and streams that provide electricity through waterpower, important aquatic habitats and drinking water. There is no resource that is of greater importance to our survival and quality of life.
