Name of Toronto
John Graves Simcoe identified the area as a strategic location to base a new capital for Upper Canada, believing Newark to be susceptible to American invasion. A garrison was established at Garrison Creek, on the western entrance to the docks of Toronto Harbour, in 1793; this later became Fort York. The settlement it defended was renamed York on August 26, 1793, as Simcoe favoured English names over those of First Nations languages, in honour of Prince Frederick, Duke of York. Residents petitioned to change the name back to Toronto, and in 1834 the city was incorporated with its original name. The name York lived on through the name of York County (which was later split into Metropolitan Toronto and York Region), and continues to live on through the names of several districts within the city, including Yorkville, East York, and North York, the latter two suburbs that were formally amalgamated into the "megacity" of Toronto on January 1, 1998.
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.
