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.
York, Toronto
York Township was home to one of the original Black communities in the Toronto area, which was populated by many African American fugitive slaves. By 1861, the township had the second-largest Black population in the Toronto area, after St. John's Ward, most of whom lived in York Township West (located west of Yonge Street and north of Bloor Street). The legacy of York's original Black community continues today; as of the 2011 Census, 15.9% of York's population is Black, the largest percentage of all six former boroughs.
