Plan ahead: Montreal's REM taking a 6-week 'summer break' starting Saturday | CityNews Montreal

Montreal's REM (Réseau express métropolitain) will be closed for six weeks during the summer of 2025 due to construction work and system upgrades. The closure will begin on June 30, 2025, resulting in transportation disruptions and adjustments. Commuters are advised to plan alternative routes and consider available public transit options. The construction aims to improve the functionality and reliability of the system, ultimately providing better service to passengers once completed. The city plans to communicate updates and details to minimize the impact on daily travel.
