Ontario Highway 27 - Route Description

Route Description

Highway 27 followed a mostly straight route throughout its length. Between Toronto and the York–Simcoe boundary at Highway 9, it travelled along the 7th concession road west of Yonge Street. North of there it is generally parallel to the Penetanguishene Road and Highway 400. North of Kleinburg, the vast majority of the highway was surrounded by rural farmland.

The highway began at off-ramps from the collectors lanes of Highway 427, which was redesignated from Highway 27 in 1972, as a four-lane divided expressway. Through Etobicoke, it encountered mostly industrial surroundings. Within the Regional Municipality of York, Highway 27 passed along the western edge of suburban sprawl in Vaughan, near the community of Woodbridge. South of Kleinburg, the highway dipped into the Humber River valley, connecting with Islington Avenue. North of the valley, it continued through King Township into the Oak Ridges Moraine, dividing the village of Nobleton and entering Schomberg immediately south of Highway 9, north of which the highway entered Simcoe County.

It travelled through the village of Bond Head and thereafter met Highway 89 in Cookstown. As the highway approached Barrie, it curved and followed Essa Road northeast until it met Highway 400. Through Barrie, it was concurrent with Highway 400 between Exit 94 and Exit 98, after which it was concurrent with Highway 26 along Bayfield Street, travelling north and exiting the city. At Midhurst, Highway 27 diverged from its concurrency to continue north, parallel to and 4 km (2.5 mi) west of Highway 400.
