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
Between 1710 and 1750, French traders established two trading posts on the Humber River, Magasin Royale, and Fort Toronto. The success of Fort Toronto led the French to build Fort Rouillé on the current Exhibition grounds in 1750. It only lasted until 1759, abandoned after the fall of Fort Niagara, when the French retreated to Montreal. The British arrived the next year with an army to secure the location. The British claimed all of New France after the 1763 Treaty of Paris, and extended the Province of Quebec to present-day Ontario.
