The new 815 bus service will link Des Sources REM station with Montreal‑Trudeau Airport, starting mid‑June 2026 and running through the fall. It is aimed at West Island residents and will give a direct public‑transit link between the REM line and the airport.
The route begins at the Des Sources station on the REM network and travels to the airport terminals, providing a scheduled connection for commuters and travelers. The service operates all summer and will continue into the autumn months, with the route designated as 815.
Local officials said the addition of the bus line was intended to improve accessibility between the West Island and the international airport. By offering a dedicated shuttle, the transit agency hopes to give riders an alternative to driving, easing traffic and expanding options for those who rely on public transportation.
The new service joins existing transit options that serve the airport, adding a direct link from the western suburbs. Residents of the West Island can now board the 815 bus at Des Sources and reach the airport without transferring to other lines. The schedule will be posted on the transit authority’s website and at the station, with regular departures throughout the day.
The introduction of route 815 expands the summer timetable of the city’s transit network. Riders will have the possibility to travel from the West Island to the airport without using a car, aligning with the region’s goal of promoting sustainable travel. The service is expected to operate at regular intervals throughout the day, matching peak flight times and commuter demand.
