York was incorporated and renamed Toronto in 1834, leading to the first Toronto elections.
Toronto's first mayor William Lyon Mackenzie, a reformer, persisted in his efforts to reform Upper Canada, culminating in his organization of a rebellion in 1837.
To support the suburban growth, the Government of Ontario set up Metropolitan Toronto, a regional government encompassing Toronto and its suburbs, in 1954.
The regional government built roads, water treatment and highways in Toronto, although the central city remained the largest municipality and occasionally defeated regional projects, such as the Spadina Expressway and other expressways and the clearing of the Toronto Islands.
Simcoe originally planned for York to be a city and military outpost and to set up a capital in the area of London, Ontario, but he abandoned the plan and York was named the permanent capital in 1796.
