The Greater Toronto Area is the most populous metropolitan area in Canada with 5,583,064 people living in the census metropolitan area as of 2011. Classified as an alpha global city by the GaWC, Toronto is an international centre of business, finance, arts, and culture. The area now called Toronto has been inhabited for thousands of years by various Aboriginal peoples. The urban history of the city dates back to 1787, when British officials negotiated the Toronto Purchase with the Mississaugas of the New Credit. They established the Town of York, and later designated it as the capital of Upper Canada. During the War of 1812, York was ransacked and heavily damaged by U.S. troops in the Battle of York. The town was renamed and incorporated as the City of Toronto in 1834, and became the capital of the province of Ontario in 1867.
