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. Of the various watercourses that drained Toronto, the Don, the Humber River, and the Rouge River have headwaters in the Oak Ridges Moraine.
The Don is formed from two rivers, the East and West Branches, that meet about 7 kilometres (4 mi) north of Lake Ontario while flowing southward into the lake. The area below the confluence is known as the lower Don, and the areas above as the upper Don. The Don is also joined at the confluence by a third major branch, Taylor-Massey Creek. The Toronto and Region Conservation Authority (TRCA) is responsible for managing the river and its surrounding watershed. The Source of the River is the Oak Ridge Moraine and the basin is 360 Km2 . The average flow of the river is 4 m3/s.
The Humber River is a river in Southern Ontario, Canada. It is in the Great Lakes Basin, is a tributary of Lake Ontario and is one of two major rivers on either side of the city of Toronto, the other being the Don River to the east. It was designated a Canadian Heritage River on September 24, 1999.
The Humber collects from about 750 creeks and tributaries in a fan-shaped area north of Toronto that encompasses portions of Dufferin County, the Regional Municipality of Peel, Simcoe County, and the Regional Municipality of York. The main branch runs for about 100 kilometres (60 mi) from the Niagara Escarpment in the northwest, while another other major branch, known as the East Humber River, starts at Lake St. George in the Oak Ridges Moraine near Aurora to the northeast. They join north of Toronto and then flow in a generally southeasterly direction into Lake Ontario at what was once the far western portions of the city. The river mouth is flanked by Sir Casimir Gzowski Park and Humber Bay Park East. The Source of the River is the Huber Spring Pond and the basin is 903 Km2 .
The Rouge River is a river in Markham, Pickering, Richmond Hill and Toronto in the Greater Toronto Area of Ontario, Canada. The river flows from the Oak Ridges Moraine to Lake Ontario at the eastern border of Toronto, and is the location of Rouge Park, the only national park in Canada within a municipality. At its southern end, the Rouge River is the boundary between Toronto and southwestern Pickering in the Regional Municipality of Durham. The Source of the River is the Oak Ridge Moraine and the basin is 336 Km2 . The average flow of the river is 1.76 m3/s.
Former rivers of Toronto
The city also has many rivers that were buried or completely removed to make way for development and the rapid expansion of the city.
