McCowan Road is a major north–south thoroughfare in the Greater Toronto Area in Ontario, Canada. It runs through the city of Toronto and into the Regional Municipality of York where it ends at the Town of Georgina.
The road was named for the McCowan Family, a Scottish family patriarch who settled in the area in 1833. The street, the former Lot 22, and later McCowan's Sideroad (officially named McCowan Road by Scarborough Township in 1956), begins at Kingston Road in the City of Toronto and ends at Baseline Road in the Town of Georgina.
In Scarborough, there is a brief break at the Highland Creek between Lawrence and Eglinton Avenues; Danforth Road carries most of the traffic south-southwest of Lawrence. When the Scarborough Town Centre complex opened in 1973, an interchange with Highway 401 was opened. With greater vehicle usage, in that area, the road is now six lanes from Ellesmere Road to Sheppard Avenue, and additional exit ramps to/from the 401 have been constructed at nearby Brimley Road.
