Scarborough (/ˈskɑːrbʌroʊ/; 2021 Census 629,941) is a district of Toronto, Ontario, Canada. It is situated in the eastern part of the City of Toronto. Its borders are Victoria Park Avenue to the west, Steeles Avenue and the city of Markham to the north, Rouge River and the city of Pickering to the east, and Lake Ontario to the south. Scarborough was named after the English town of Scarborough, North Yorkshire, inspired by its cliffs.
Scarborough, which was settled by Europeans in the 1790s, has grown from a collection of small rural villages and farms to become fully urbanized and diverse cultural community. Incorporated in 1850 as a township, the district became part of Metropolitan Toronto in 1953 and was reconstituted as a borough in 1967. The borough rapidly developed as a suburb of Toronto over the next decade and became a city in 1983. In 1998, the city 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 – now houses offices of the municipal government of Toronto.
