William Lyon Mackenzie
The township of York, which until 1793 had been known as "Toronto", incorporated as a city (meaning it received local self-government) on March 6, 1834, taking the name of "the City of Toronto" to distinguish it from New York City and the dozen other settlements named 'York' in Upper Canada. The Tories and the Reformers fielded candidates for Toronto's first municipal election, held on March 27, 1834, with the Reformers winning a majority on the Toronto City Council. Mackenzie was elected as an alderman. The City Council then met to decide who should become mayor. Mackenzie, after being nominated by Franklin Jackes, defeated John Rolph in the vote and thereby became the first Mayor of Toronto.
New Toronto
In 1953 the Town of Mimico, Town of New Toronto, Village of Long Branch, Etobicoke Township, Village of Swansea, Village of Forest Hill, Village of Weston, Town of Leaside, East York Township, North York Townsip, York Township, Scarborough Township and City of Toronto joined together to create a new common level of government: Metropolitan Toronto (Metro). Each municipality retained its own town council and government, but several infrastructure departments were transferred to Metro. This lasted until 1967, when the number of municipalities in Metro was reduced.
