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.
Government House (Ontario)
After the destruction of the Fort York house, York did not have another Government House until after the War of 1812. In 1815 the government purchased Elmsley House, a more commodious Georgian residence for its Lieutenant Governor. The next Government House was located in a wooded area to the west of the settled portion of the (then) Town of York, roughly midway on the block now occupied by Roy Thomson Hall and Metro Hall in downtown Toronto. Built in 1798, the residence had been the home of the Chief Justice and Speaker of the Legislative Assembly, John Elmsley, and it served as the colony's Government House from 1815 to 1841 (and intermittently from 1841 to 1858, during some of the times when Toronto served as the capital of the Province of Canada). For many years after its purchase by the government, the residence was still known by the name of its former owner, with the correspondence of the Lieutenant-Governor typically dated from "Elmsley House".
