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. Highway27 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 from Highway 427 north to Mimico Creek is under provincial jurisdiction. Highway27 was created in 1927, connecting Barrie with Penetanguishene. It was extended south to Schomberg in 1934, and later to Toronto by the late 1930s. The route served as a redundancy to Yonge Street, and later Highway 400. Through the 1950s, the portion of Highway27 between Evans Avenue and north of Eglinton Avenue was expanded into a four-laned dual highway known as the Toronto Bypass (which included portions of the new Highway401 through Toronto). Beginning in the mid-1960s, this dual highway was expanded into the current collector–express system and renumbered as Highway427 upon completion at the end of 1971. The majority of the remainder of the route was decommissioned in the late 1990s; the majority of the former highway is now known as York Regional Road27 and Simcoe County Road27, though it retains its Highway27 name within the City of Toronto. Route description As of 2021, Highway27 begins to the south at the offramps from the collector lanes of Highway427 as a four-lane divided highway. While the express lanes, constituting the mainline Highway427, curve around the Richview Memorial Cemetery and shift west by approximately 1km (0.6mi), the collector lanes transitioning to Highway27 continue northward and cross Eglinton Avenue at a half-cloverleaf interchange (originally meant for the never-built Richview Expressway before diving under Highway401. Highway27 ends north of Mimico creek at the end of the divided highway, transitioning into an arterial road of the same name. Former route (1997) Through Etobicoke, it encountered mostly industrial surroundings, meeting Dixon Road at a cloverleaf interchange near the Toronto Congress Centre, then crossing (but not interchanging with) Highway 409. Highway27 followed a mostly straight route throughout its length, as it passed through the suburbs of Toronto, then north of Kleinburg the vast majority of
