Don River

Covering an area of approximately 36,000 hectares, the Don River stretches almost 38 km in length, flowing south from its headwaters on the Oak Ridges Moraine to the Keating Channel, where it empties into Lake Ontario.

With 1.2 million residents, the Don River watershed is one of the most urbanized in Canada. Despite the challenges associated with this urbanization, the landscape of the Don River is slowly being regenerated and revitalized.

Today, the Don Valley and its network of trails provide people with a unique connection to nature in the heart of the city. TRCA celebrates the natural heritage of the Don with annual events such as Paddle the Don and Mill Pond Splash.
