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.
Fort York
In 1793, Lieutenant Governor John Graves Simcoe authorized a garrison on the present site of Fort York, just west of the mouth of Garrison Creek on the north western shore of Lake Ontario. Simcoe recognized Toronto was an ideal site for settlement and defence because of its natural harbour and relative longer distance from the United States. Fort York guards the western (at the time of construction, the only) entrance to the bay. Simcoe had decided to make Toronto (which he renamed York) the capital of Upper Canada, and the government, the first parliament buildings and the town were established one and a half miles east of the fort (near the foot of the present Parliament Street).
