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.
Metropolitan Street Railway (Toronto)
On August 16, 1922, the City of Toronto formally acquired the T&YRR lines. The plan was that the city portions of the T&YRR radial lines would be incorporated into the TTC, and the portions outside the city would be managed by Ontario Hydro as the Hydro-Electric Railways: Toronto and York Division. 
On November 1, 1922, Hydro-Electric Railways took over operation of the T&YRR lines outside of the city limits. Hydro initiated a number of line improvements including track rehabilitation, a new station at Schomberg Junction, new waiting shelters, more passing sidings and additional service to Thornhill and Bond Lake Park.
