The five REM stations from Brossard station to Gare Centrale station (excluding Griffintown-Bernard-Landry station) are in service.

The opening date of the stations in direction of Anse-à-l’Orme and Deux-Montagnes, as well as the section of the main line between McGill and Bois-Franc, will be determined by the progress of spring 2024 tests. The commissioning of the branch towards YUL-Aéroport-Montréal-Trudeau is scheduled in 2027. Consult the work schedule for more information.
