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.
Greater Toronto Area
The first large influx of European settlers to settle the region were the United Empire Loyalists arriving after the American Revolution, when various individuals petitioned the Crown for land in and around the Toronto area. In 1787, the British negotiated the purchase of more than a quarter million acres (1,000 km²) of land in the area of Toronto with the Mississaugas of New Credit. York County, would later be created by Governor John Graves Simcoe in 1792, which would at its largest size, comprise all of what is now Halton Region, Toronto, Peel Region, York Region and parts of Durham Region. The Town of York (present-day Toronto) would later be attacked by American forces in the War of 1812 in what is now known as the Battle of York, in 1813.
