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.
Government House (Ontario)
After the destruction of the Fort York house, York did not have another Government House until after the War of 1812. In 1815 the government purchased Elmsley House, a more commodious Georgian residence for its Lieutenant Governor. The next Government House was located in a wooded area to the west of the settled portion of the (then) Town of York, roughly midway on the block now occupied by Roy Thomson Hall and Metro Hall in downtown Toronto. Built in 1798, the residence had been the home of the Chief Justice and Speaker of the Legislative Assembly, John Elmsley, and it served as the colony's Government House from 1815 to 1841 (and intermittently from 1841 to 1858, during some of the times when Toronto served as the capital of the Province of Canada). For many years after its purchase by the government, the residence was still known by the name of its former owner, with the correspondence of the Lieutenant-Governor typically dated from "Elmsley House".
