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.
John Graves Simcoe
John Graves Simcoe (25 February 1752 – 26 October 1806) was a British Army general and the first Lieutenant Governor of Upper Canada from 1791 until 1796 in southern Ontario and the watersheds of Georgian Bay and Lake Superior. He founded York (now Toronto) and was instrumental in introducing institutions such as courts of law, trial by jury, English common law, and freehold land tenure, and also in the abolition of slavery in Canada.
