Wetlands cover about 14% of Canada today. They were once abundant but became increasingly scarce due to land use practices that destroyed vegetation, polluted their water sources, and altered their water flow. Over two thirds of the original wetlands in southern Ontario have vanished, for example. Along the shores of Lakes Erie and Ontario, 90 – 95% of the wetlands have been destroyed due to urban development and agricultural production. Fortunately, most of the wetlands in the North survive.
