Overnight maintenance work carried out by an external partner has pushed back the scheduled reopening of Montreal’s REM light‑rail network on Saturday, July 11, 2026. The delay follows a series of planned maintenance activities that were already expected to affect service over the weekend. The REM operator confirmed that the additional work performed during the early‑morning hours extended the time needed before trains could resume normal operations.
The REM network had been slated to restart service after the weekend maintenance window, but the extra tasks required by the external contractor meant that the planned restart time could not be met. Operators indicated that the delay was directly linked to the scope of the overnight work, which involved technical checks and repairs that could not be completed within the original timeframe. As a result, commuters looking to travel on the REM later in the day will encounter a later-than‑anticipated opening of stations and lines.
The situation adds to disruptions that were already forecast for the weekend due to the broader maintenance program. Riders are advised to check the REM’s service updates for the revised opening time and to consider alternative transportation options if needed. The REM authority and its maintenance partner have not provided a specific new start time, but they emphasized that safety and system integrity remain the priority as work continues to be finalized.
