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, Upper Canada
The original townsite was a compact ten blocks near the mouth of the Don River and a garrison was built at the channel to Toronto Harbour. Government buildings and a law court were established. Yonge Street was built, connecting York to the Holland River to the north. To the east, Kingston Road was built to the mouth of the Trent River. In 1797, the town site was expanded to the west to allow for public buildings and expansion. One of the new area's public functions, a public market, was started in 1803. It continues today as St. Lawrence Market.
