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.
Metropolitan Toronto
Prior to the formation of Metropolitan Toronto, the municipalities surrounding the central city of Toronto were all independent townships, towns and villages within York County. After 1912, the city no longer annexed suburbs from York Township. At times, the suburbs asked to be annexed into Toronto, but the city chose not to do so.
