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.
Fort York
In 1793, Lieutenant Governor John Graves Simcoe authorized a garrison on the present site of Fort York, just west of the mouth of Garrison Creek on the north western shore of Lake Ontario. Simcoe recognized Toronto was an ideal site for settlement and defence because of its natural harbour and relative longer distance from the United States. Fort York guards the western (at the time of construction, the only) entrance to the bay. Simcoe had decided to make Toronto (which he renamed York) the capital of Upper Canada, and the government, the first parliament buildings and the town were established one and a half miles east of the fort (near the foot of the present Parliament Street).
