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.
York, Upper Canada
After the war was over, the town continued to grow, expanding to the west, leaving the original town site, a less desirable location, somewhat undeveloped. A new parliament building was erected, near the original location, but this burned down and a new building was built in the new lands to the west. A permanent fort, Fort York, was built on the site of the garrison. Dundas Street was built to connect York to towns to the west. In the 1820s, the town experienced a surge of immigrants, expanding from 1,000 residents to over 9,000 by the time the town was incorporated as the City of Toronto in 1834. During its existence, the town did not have its own government; it was governed by the province of Upper Canada, with a mix of elected officials and an aristocracy known as the Family Compact controlling the government. By 1830, this led to an ongoing political conflict, which would later lead to the 1837 Upper Canada Rebellion.
When Europeans first arrived at the site of York, the vicinity was inhabited by the Iroquoian Seneca tribe (from the Five Nations Iroquois of New York State), who by then had displaced the Wyandot (Huron) tribes that had occupied the region for centuries before c. 1600. By 1701, the Iroquoian villages that had been established along the north shore of Lake Ontario during the sixteenth century had been abandoned. The Algonkian Mississaugas then moved into the York region, created alliances with the former Iroquoian residents, and established their own settlements; one near the former Seneca village of Teiaiagon on the Humber River.
