King's Highway 50, commonly referred to as Highway 50, was a provincially maintained highway in the Canadian province of Ontario. The highway, which was decommissioned in 1998, is still referred to as Highway 50, though it is now made up of several county and regional roads: Peel Regional Road 50, York Regional Road 24 and Simcoe County Road 50. The route began in the north end corner of the former Etobicoke at Highway 27 as Albion Road, and travelled northwest to Highway 89 west of the town of Alliston. En route, it passed through the villages of Bolton, Palgrave and Loretto. The road south of Bolton has become more suburban as development has encroached from the east and west; but despite this increased urbanization, the removal of highway status, and the fact that it runs through the former Albion Township, the Albion Road name has not been extended to follow it outside Toronto.

King's Highway 27, commonly referred to as Highway 27, is a provincially maintained highway in the Canadian province of Ontario. The Ministry of Transportation of Ontario was once responsible for the length of the route, when it ran from Long Branch to Highway 93 in Waverley. Highway 27 followed a mostly straight route throughout its length, as it passed through the suburbs of Toronto, then north of Kleinburg the vast majority of the highway was surrounded by rural farmland. Today, only the southernmost 1.6 km (1 mi) from Highway 427 north to Mimico Creek is under provincial jurisdiction, the remainder of the route is maintained by the city of Toronto, York Region and Simcoe County.
