The Réseau express métropolitain (REM; lit. 'Metropolitan Express Network') is a light metro rapid transit system in Greater Montreal, Quebec, Canada. As of June 2025, it consists of five stations spanning 16 km, connecting Downtown Montreal with the suburb of Brossard. Extensions to the West Island and the northwestern Montreal suburbs will open in October 2025 and a further extension to the Montréal–Trudeau International Airport will open in 2027. A portion of the route was taken over from the Exo commuter rail Deux-Montagnes line and has been converted to light metro standards.
The 67-kilometre (42 mi) light metro rail system is projected to cost CA$8.34 billion. It is independent of, but connects to and hence complements, the existing Montreal Metro, operated by the STM. Trains on the network are fully automated and driverless, and the stations are completely enclosed and climate controlled, featuring platform screen doors.
The line has been built by CDPQ Infra, a subsidiary of the Caisse de dépôt et placement du Québec, an institutional investor that manages various public and para-public pension plans and insurance programs in Quebec. The first section of the REM opened on 31 July 2023.
