History of Toronto
In 1998, the six municipalities comprising Metropolitan Toronto – East York, Etobicoke, North York, Scarborough, York, and the old City of Toronto – and its regional government were amalgamated into a single City of Toronto (colloquially dubbed the "megacity") by an act of the Government of Ontario. This was despite a municipal referendum in 1997 that was overwhelmingly against amalgamation. Subsequently, Mel Lastman defeated Barbara Hall to become the first elected mayor of the megacity.
York, Toronto
York Township was incorporated by Canada West in 1850 (Canada West later became Ontario in 1867, due to Confederation), bounded in the west by the Humber River, in the east by what would become Victoria Park Avenue, and in the north by what would become Steeles Avenue. Etobicoke Township and Scarborough Township were located west and east, respectively, while the townships of Vaughan and Markham bordered on the north.
