Rolling stock maintenance is effected in four facilities, in three locations.
Two small tracks are located at Montmorency and Beaugrand garages, and two large are at the Plateau d'Youville facility.
A fifth facility is under construction at the Cote-Vertu garage.

Plateau d'Youville is a facility in the north end of the city located at the intersection of Crémazie and Saint-Laurent Boulevards.
It provides heavy maintenance of buses, Metro cars, light maintenance of MR-73 Metro cars and is the main base for the track maintenance workshops (where track sections are pre-assembled prior to installation).
