- This article is about the river in Toronto, Canada. For other rivers with the same name, see Don River (disambiguation).
The Don River is one of two rivers bounding the original settled area of Toronto,
Canada along the shore of Lake Ontario, the other being the Humber River to the west. The Don is formed from two rivers, the East and West Branches, that
meet about 7 km 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 eastern arm of the rivers starts near the Oak Ridges Moraine just to the west
of Yonge Street, flowing south-eastward through ravine forests in Richmond Hill, Thornhill, east of Willowdale and Don Mills. A second branch of the eastern Don,
known as German Mills Creek, parallels the main eastern branch and joins it at
Steeles Avenue, the northern boundary of Toronto.
The western arm starts near the area of Maple, flowing south-east through the suburban
industrial belt of Concord (Vaughan), and the
G. Ross Lord Reservoir. It crosses Yonge Street as it flows through Hoggs Hollow, past York University's Glendon ("valley of the Don") campus, and then flows on to Leaside
before joining the eastern half.

Parkway as it exits onto the elevated Gardiner Expressway seen in the background. Note the algae covering most of the
river.

Charles Sauriol Conservation Reserve is located near the forks of the Don River. It was at one time home of a Maple sugar shack and tapline, which was visited yearly by students from across East York. Charles Sauriol Conservation Reserve is a rarely used area of the river valley.
Charles Sauriol was a historic protector of the Don.
In 1788, Alexander Aitkin, an English surveyor who worked in southern Ontario,
referred to the Don River as NeCheng qua kekonk.[1].
Elizabeth Simcoe, wife of Lieutenant Governor John
Graves Simcoe, reported in her diary that another named used was Wonscotanach.[2] This is an Anishnaabe phrase
meaning back burnt grounds which could refer to an earlier forest fire. The Don River was named by J.G. Simcoe because the
wide valley reminded him of the River Don in Yorkshire.
In the 1880s the lower part of the Don south of the former Winchester St. bridge was straightened (east of the original mouth)
and placed in a channel to create additional harbour space and industrial dock space for boats. Known as the Don Improvement
Project it also turned the river mouth 90 degrees west where it empties into the inner harbour. This short extension of the
harbour is known as the Keating Channel. The channel north of Lake Shore Blvd. East ceased being navigable when the Gardiner Expressway was constructed in the 1950s. Boats may still enter the Keating channel by going
underneath a lift bridge at Cherry St. In late 2000, several plans were being drawn up to redevelop the area, including
relocating the mouth closer to its original location, and developing a canal system around the area.
The Don had been heavily developed in the earlier portions of the 20th century, with
several factories, two rail lines and then a freeway, the Don Valley Parkway, being built in the river valley. The last of the industrial plants, Domtar
Polyresins, closed in the 1980s and has since been reused as the Toronto Police Force
K-9 training site. The only remaining industrial use on urban portions of the river is the
North Toronto Sewage Treatment plant, whose use is currently under review.
The western section of Taylor-Massey Creek and the southern portion of the western branch are surrounded by parkland. In more
recent years the retreat of the industrial plants and rail infrastructure has freed up room which is now being turned into
bicycling trails, which now extend from the shore of Lake Ontario northward in several
directions to provide some 30km of off-road paved trails. While Toronto is fairly flat in general, local cyclists have developed
a number of technically challenging singletrack trails throughout the
area, following the main trails.
