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.
City of Toronto Act
The Incorporation of the City of Toronto on March 6, 1834, was a legislative act creating the City of Toronto from the unincorporated town of York. This allowed for the creation of the local government or city council. The act was transferred onto the succeeding governments of Ontario in 1840 and 1867. The incorporation remained in effect throughout Toronto's mergers with other cities and towns within southern York County until the creation of Metropolitan Toronto in 1954.
