New branch of Montreal’s REM is second-longest aerial rail network in Canada

Carl Corbel is director of operations with the infrastructure division of Caisse de dépôt et placement du Québec, the province’s public pension fund manager and owner of the REM.

He says passengers in the West Island — a region known for inadequate public transit — will be able to travel from the Anse-à-l’Orme station to downtown Montreal in 35 minutes.

The segment was initially scheduled to go into service at the end of 2024. The deadline was pushed back twice, first to fall 2025 then spring 2026.

The final section of the REM linking to Montréal Trudeau International Airport is expected to open by the end of 2027.

In the meantime, the Aéroports de Montréal says it will fund a shuttle service linking the Des Sources station to the airport, which it expects to launch mid-June.

An agreement between the airport and the agency that plans, finances and organizes integrated transit in Greater Montreal — Autorité régionale de transport métropolitain — is being finalized.

In October 2025, CDPQ Infra promised to open the airport station in 2027. Julien Hurel, vice-president of the REM project at CDPQ Infra, says there are “no major challenges” to meet that deadline.

The REM’s timelines have been delayed several times, and it has faced criticism over outages on the Brossard branch linking to Montreal’s South Shore since it was launched.

Hurel said many of these issues have been addressed since the REM was first inaugurated in 2023.

“We have basically divided by two the number of breakdowns while we tripled the overall network,” he says.

When completed, the network will comprise 26 stations over 67 km of track across the greater Montreal area.
