Region Overview

The Metro Toronto Region includes the area roughly bordered geographically by Lake Ontario to the south, Steeles Avenue to the north, Highway 427 to the west, and Regional Road 30 to the east. The Metro Toronto Region comprises the municipality of Toronto. The region is divided into two sub-regions:

  • Central Downtown Sub-region: This area covers the area extending northward from Lake Ontario to within 0.5 km of Highway 401, westward to the Humber River, and eastward to Victoria Park Avenue. The sub-region includes the core of the city, and is made up mainly of commercial towers, multi-unit residential and condominium towers, and mixed residential and commercial land uses. The downtown area has been identified in the City of Toronto Official Plan as an important area for future growth, and the current pace of building development indicates that growth is well underway. 
  • Northern Sub-region: This area is roughly bordered geographically by Highway 401 on the south, Steeles Avenue on the north, Highway 427 on the west, and Regional Road 30 on the east, in addition to the area east of the Don Valley Parkway and north of O’Connor Dr. This sub-region comprises the northern portion of the municipality of Toronto.
