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.
The Annex
European settlement of this area began in the 1790s when surveyors laid out York Township. The area east of Brunswick Avenue became part of the village of Yorkville, while the region west of Brunswick was part of Seaton Village. In 1883, Yorkville agreed to annexation with the City of Toronto. In 1886, Simeon Janes, a developer, created a subdivision which he called the Toronto Annex. The Annex area became part of Toronto in 1887 and Seaton Village joined Toronto in 1888.
