Westmount Collegiate Institute is a high school in the Thornhill, Ontario district of the greater city of Vaughan.

The community centre, which is attached to the northern edge of the school, contains an arena, a split gymnasium, and recreational rooms used for different events and programs, such as playing bridge.

[3] Adjoining Westmount from the southern portion of the complex, the City Playhouse is a 386-seat, community-based theatre featuring a wide variety of professional, community and school productions.

Attached to the west side of the complex, the Butternut Child Centre is a preschool which exists for children aged four and younger.

The older Milliken Mills High School in Markham, Ontario, built in 1988, has a similar layout on the inside to the two; however, it contains a very different façade and décor.
