Hillcrest Complex, the Toronto Transit Commission's largest facility, is responsible for most of the maintenance work on the system's surface vehicles, including heavy overhauls, repairs, and repainting. It is located adjacent to the intersection of Bathurst Street and Davenport Road. The site is also home to the TTC's Transit Control Centre, but the operational headquarters of the organization remains at the McBrien Building, at 1900 Yonge Street.
Hillcrest Complex occupies an area of about 13 hectares (32 acres) with a frontage of 270 m (890 ft) along Bathurst Street and 420 m (1,380 ft) along Davenport Road.
