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.
Old Toronto
Old Toronto is the retronym of the area contained within the original boundaries of Toronto, Ontario, Canada, from 1834 to 1998. It was first incorporated as a city in 1834, after being known as the town of York, and became part of York County. In 1954, it became the administrative headquarters for the Regional Municipality of Metropolitan Toronto. The city expanded in size by annexation of surrounding municipalities, reaching its final boundaries in 1967. Finally, in 1998, it was amalgamated with the other cities of Metropolitan Toronto (York, North York, Etobicoke, Scarborough); and the borough of East York, into the present-day city of Toronto. This was not a traditional annexation of the surrounding municipalities (where a city absorbs the said municipalities but officially remains the same city), but rather a new municipal entity that is the successor of the original city.
