A service delay is affecting the whole REM network during commute hours Tuesday morning.
The transit agency posted on X, shortly before 8:00 a.m., that “technical problem” was the cause for the delays without providing more details.

Journal de Montréal reported earlier Tuesday that since the Deux-Montagnes branch opened, REM has seen 16 service outages — roughly one every four days.
