Weston is a neighbourhood and former town in Toronto, Ontario, Canada. The neighbourhood is situated in the northwest of the city, south of Highway 401, east of the Humber River, north of Eglinton Avenue, and west of Jane Street. The eponymous Weston Road, just north of Lawrence Avenue is the historic core of Weston, with many small businesses and services. Weston was incorporated as a village in the 19th century and was absorbed into the Borough of York in the late 1960s. York itself was amalgamated into Toronto in 1998. Weston is one of the few former towns and villages in Toronto located in a generally suburban setting, although it is contiguous with the inner city to the southeast along Weston Road. It is also one of the few not developed as a planned satellite town, as is the case with Leaside or New Toronto.

Toronto is the most populous city in Canada and the capital city of the Canadian province of Ontario. With a population of 2,794,356 in 2021, it is the fourth-most populous city in North America.
