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.
Etobicoke
In 1954, Etobicoke Township became a part of the newly formed regional government, the Municipality of Metropolitan Toronto ("Metro"). In 1967, the township of Etobicoke was merged with three small lakeside municipalities — the Village of Long Branch, the Town of New Toronto, and the Town of Mimico — to form the Borough of Etobicoke. The borough was reincorporated as a city in 1984. In 1998, six local municipalities (including Etobicoke) and the Metropolitan Toronto government merged to form the amalgamated city of Toronto.
