The third branch of Montreal’s new light rail network is set to open on May 18.
The Réseau express métropolitain (REM)’s Anse-à-l’Orme branch will extend the network by 14 kilometres, adding four new stations in the cities of Pointe-Claire, Kirkland and Sainte-Anne-de-Bellevue.
The stations are:
Des Sources.Fairview–Pointe-Claire.Kirkland.Anse-à-l’Orme.
STM and exo lines have also been adjusted to facilitate connections to the network.
“As a result, nearly a dozen additional municipalities and boroughs can now access the REM,” the REM wrote in a post on X announcing the planned opening date.
“This marks an important milestone for mobility in the West Island: the REM becomes the first high-frequency structured public transit network to serve the area.”
The Anse-à-l’Orme branch was initially scheduled to open in 2024.
Once it opens, the REM will have 23 stations, 63 kilometres of network and 3 branches, including the Deux-Montagnes line — which opened in November 2025 though it was originally supposed to start running in 2024 — and the South Shore branch, launched in 2023, but initially expected to operate in 2021.
Public transit users will still have to wait until the end of 2027 for the opening of the REM’s airport connection.
Since its launch in 2023, the system has been plagued by service disruptions due to technical problems and Montreal’s harsh winter weather.
