Covering an area of approximately 36,000 hectares, the Don River stretches almost 38 km in length. It flows south from its headwaters on the Oak Ridges Moraine to the Keating Channel in Toronto, where it empties into Lake Ontario.
Home to 1.2 million residents, almost half of the Don watershed is devoted to housing, leaving little undeveloped land left. The pressures of urbanization have presented many environmental challenges for the air we breathe, the water we drink, and the earth to grow our food. Despite these challenges, the landscape of the Don River is slowly being regenerated and revitalized, and its natural heritage celebrated through annual events such as Paddle the Don and Mill Pond Splash.
