Woodbridge is a very large suburban community in Vaughan, Ontario, Canada, along the city's border with Toronto. It occupies the city's entire southwest quadrant, west of Highway 400, east of Highway 50, north of Steeles Avenue, and generally south of Major Mackenzie Drive. It was once an independent town before being amalgamated with nearby communities to form the city in 1971. Its traditional downtown core is the Woodbridge Avenue stretch between Islington Avenue and Kipling Avenue north of Highway 7.
