Map of the Area of the 1 August 1805 Treaty [Toronto Purchase]

Historical Background: Due to the growth of York, and since it was the seat of government, Lieutenant-Governor Peter Hunter, decided that it was time to settle the land dispute over this tract of land, referred to as the Mississauga Tract. It was also an opportune time to commence negotiations with the Mississaugas, since Joseph Brant's was no longer the land agent for the Mississaugas.

The Deputy Superintendent of Indian Affairs, William Claus, negotiated and at Credit River, 31 July 1805 the Mississaugas relinquished 250 800 acres of land that included York for 1000 pounds Quebec currency worth of goods. Further land was acquired from the Mississauga Tract to expand the Toronto Purchase in 1818 and 1819.
