King's Highway 27, commonly referred to as Highway 27, is a provincially maintained highway in the Canadian province of Ontario, much of which is now cared for by the city of Toronto, York Region and Simcoe County. 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.
