Overview

• CDPQ Infra says the Deux‑Montagnes branch from Central Station will begin service in November 2025.
• The Anse‑à‑l’Orme branch to the West Island along Highway 40 is now slated to open in spring 2026.
• The latest schedule follows earlier plans that slipped from a late‑2024 launch to a fall 2025 target that had been eyed for October.
• The full REM build remains planned at 26 stations over 67 kilometres, with the airport link targeted for fall 2027.
• The operator says the change does not alter the $9.4‑billion cost update and that winter reliability measures are being put in place.
