A new bus line numbered 815 is set to begin service in mid‑June 2026, providing a direct link between the Des Sources REM station on the West Island and Montreal‑Trudeau Airport. The route will run from the REM station straight to the airport terminals, giving residents of the West Island a dedicated public‑transport option for air travel.
The 815 service is scheduled to operate through the summer months and continue into the fall season. Riders will be able to board the bus at Des Sources and travel directly to the airport without needing to transfer to other services. The timetable will align with the peak travel period, ensuring availability for those heading to and from the airport during the busiest months.
City officials announced the addition of the route as part of an effort to improve connectivity between the West Island and the airport. The decision was driven by the desire to offer a more convenient alternative for commuters who currently rely on other forms of transport to reach the airport. By linking the newly opened REM station with the airport, officials aim to streamline travel for passengers originating in the western suburbs.
The new service adds a valuable option for West Island commuters during the height of summer travel. Travelers can now choose a single‑bus ride that connects directly to the airport, reducing the need for multiple transfers or private vehicle trips. The route is expected to ease congestion on existing roadways and support the broader public‑transport network in the region.
Overall, the 815 bus line expands the public‑transport infrastructure available to West Island residents, offering a straightforward, seasonal link between the Des Sources REM station and Montreal‑Trudeau Airport throughout the summer and into the fall.
