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 East
In 1914, the East Riding of York was recreated out of York Centre and York South ridings, and was defined as consisting of the township of Scarboro, and the eastern portion of the city of Toronto south of Danforth Avenue and east of Pape Avenue. The electoral district was abolished in 1924 when it was redistributed between Toronto—Scarborough and York South ridings.
