 Metro Toronto was composed of the City of Toronto, the towns of New Toronto, Mimico, Weston, and Leaside; the villages of Long Branch, Swansea, and Forest Hill;
and the townships of Etobicoke, York, North York, East York, and Scarborough.The postwar boom had resulted in rapid suburban development, and it was believed that a coordinated land use strategy and shared services would provide greater efficiency for the region.The metropolitan government began to manage services that crossed municipal boundaries, including highways, water and public transit.
