Idle trains are stored in four garages: Angrignon, Beaugrand, Saint-Charles and Montmorency.
A fifth is under construction.
Except Angrignon, they are all underground and can accommodate around 46% of the rolling stock.
Remaining trains are parked in terminus tail tracks.

Angrignon garage, west of Angrignon Line 1 terminus, is a surface building next to Angrignon Park housing six tracks accepting two nine-car trains each.

Beaugrand garage is located east of Line 1 terminus Honoré-Beaugrand.
It is entirely under the Chénier-Beaugrand Park, and its main access point is through the Honoré-Beaugrand station.
It has seven tracks and accommodates light maintenance on MR-63 cars with two test tracks.

Saint-Charles garage, north of Henri-Bourassa terminus, is located under Gouin Park.
With eight tracks, allowing 20 trains to be parked, it is the main garage of Line 2.
Also, under Jeanne-Sauvé Park, a training facility used by the firefighters contains one of the burnt MR-63 cars from 1973 and an obsolete picking train.

Montmorency garage is built perpendicular to its terminal station to allow an easier potential expansion of the Line 2 deeper in Laval territory.

Cote-Vertu garage is under construction underground at the end of Thimens boulevard to accommodate additional MPM-10 trains on Line 2.
Accessible via a 600-metre (660 yd) tunnel, it will house a small maintenance facility and two long tracks for a total of twelve parking places.
Two more tracks could be added later with the line extension.
