A new seasonal bus service, designated 815, will begin operating in mid‑June 2026, linking the Des Sources REM station with Montreal‑Trudeau Airport. The route is scheduled to run through the summer months and continue into the fall, providing West Island residents with a direct public‑transport option to the airport for the first time this season.
The introduction of the 815 line follows calls from local officials for a stronger transit connection between the growing West Island community and the international gateway. By tying the REM station at Des Sources directly to the airport, the service aims to reduce reliance on private vehicles and offer a convenient alternative for travelers and airport employees alike.
Prior to the launch of the 815 route, the West Island had few direct public‑transport links to Trudeau Airport, leaving many commuters to depend on personal cars or indirect bus routes that required multiple transfers. The seasonal nature of the service reflects the higher travel demand during the summer tourism period, while still extending into the fall to accommodate continued passenger flow.
Local officials highlighted that the new bus line is part of a broader effort to improve mobility across the region. By integrating the REM network with airport access, the 815 route is expected to streamline journeys for passengers heading to and from the airport, as well as support the area's economic activity during the peak travel season.
Residents of the West Island have welcomed the announcement, noting that a reliable, direct bus connection will simplify travel plans and potentially lower transportation costs. The 815 service will operate on a schedule aligned with the REM timetable, ensuring coordinated transfers at Des Sources station.
The seasonal 815 bus route represents a targeted response to the longstanding gap in direct public‑transport options for West Island commuters, marking a notable enhancement to the region’s transit infrastructure for the summer of 2026 and beyond.
