Wilson Yard (also known as the Wilson Complex) is the largest of the Toronto Transit Commission's subway yards and bus garages.
The site is on a large parcel of land that was once part of Downsview Airport, built in 1936.
Modifications to the Wilson Yard were made to accommodate the new Toronto Rocket trains, the Toronto–York Spadina Subway Extension and increased demand on Line 1 Yonge–University. Work included expansion of the carhouse, a new hostler platform to support the new north-end entry/exit track, a new north-end runaround track connecting eight new storage
tracks in the west yard, a new power substation and a new training building with a simulator for TR trains.
Opened in September 2018, the new hostler platform and north-end entry/exit track helps to reduce traffic delays by 44% in the early morning when work cars return from their night shift and service trains depart.
Automatic train control is being added to all the TTC's heavy rail routes. Automatic Train Control was functional within the 60 acre Wilson Yard in 2019.
