The Don River is a watercourse in southern Ontario that empties into Lake Ontario, at Toronto Harbour. Its mouth was just east of the street grid of the town of York, Upper Canada, the municipality that evolved into Toronto, Ontario. The Don is one of the major watercourses draining Toronto that have headwaters in the Oak Ridges Moraine.
