Scarborough is an administrative district of Toronto, Ontario, Canada. Situated atop the Scarborough Bluffs, it occupies the eastern part of the city. Scarborough is contained within the borders of Victoria Park Avenue on the west, Steeles Avenue to the north, Rouge River and the city of Pickering to the east, and Lake Ontario to the south. It borders Old Toronto, East York and North York in the west and the city of Markham in the north. Scarborough was named after the English town of Scarborough, North Yorkshire.
Scarborough, which was first settled by Europeans in the 1790s, has grown from a collection of small rural villages and farms to become fully urbanized with a diverse cultural community. Incorporated in 1850 as a township, Scarborough became part of Metropolitan Toronto in 1953 and was reconstituted as a borough in 1967. Scarborough rapidly developed as a suburb of Toronto over the next decade and became a city in 1983. In 1998, Scarborough and the rest of Metropolitan Toronto were amalgamated into the present city of Toronto. The Scarborough Civic Centre – the former city's last seat of government – is occupied by City of Toronto offices.
