Wilson Yard

[7] During World War II the airport was turned into a military facility, most often known as Canadian Forces Base Downsview.

[9][10] When it finally opened, this new link provided an entry/exit to the new northern section of the yard for trains servicing the Toronto–York Spadina Subway Extension.

This avoids northbound trains going out of service after the evening rush hour having to cross the southbound track, which was the practice prior to this time.

[11] 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.

[10] 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.
