History of Toronto
In 1998, the six municipalities comprising Metropolitan Toronto – East York, Etobicoke, North York, Scarborough, York, and the old City of Toronto – and its regional government were amalgamated into a single City of Toronto (colloquially dubbed the "megacity") by an act of the Government of Ontario. This was despite a municipal referendum in 1997 that was overwhelmingly against amalgamation. Subsequently, Mel Lastman defeated Barbara Hall to become the first elected mayor of the megacity.
John Graves Simcoe
Simcoe realised that Newark made an unsuitable capital because it was on the Canada–US border and subject to attack. He proposed moving the capital to a more defensible position, in the middle of Upper Canada's southwestern peninsula between Lake Erie and Lake Huron. He named the new location London, and renamed the river there the Thames in anticipation of the change. Dorchester rejected this proposal, but accepted Simcoe's second choice, the present site of Toronto. Simcoe moved the capital there in 1793, and renamed the settlement York after Frederick, Duke of York, King George III's second son. The town was severely underdeveloped at the time of its founding so he brought with him politicians, builders, Nova Scotia timber men, and Englishmen skilled in whipsawing and cutting joists and rafters.
