Trains are expected every 6–10 minutes, carrying 500+ passengers with increased frequency during afternoon peak hours.

At 35 metres deep—the equivalent of six stories—the YUL-Aéroport-Montréal-Trudeau station will serve millions of passengers.
With the L’Anse-à-l’Orme branch set to debut this spring, and the Deux-Montagnes and South Shore sections already in operation—last but not least—the airport Réseau express métropolitain (REM) segment will be the last to open on Montreal Island.
With just a year to go before its official opening, the REM station at Montréal-Trudeau Airport is now nearly 85% complete and expected to open by the end of 2027.
The REM will provide fast and direct service to Montréal-Trudeau Airport, and will take about 25 minutes to get to Downtown Montreal.

According to a report by La Presse, once the REM is operational, one in five passengers is expected to use it, which amounts to more than 4 million people annually based on the airport’s current traffic of 22 million travellers.
Launched in 2022, the project faces unique challenges, being built beneath the airport and its multi-level parking structure, now closed and set for demolition.
The report goes on to detail that a total of 312,000 tonnes of rock were removed during excavation and repurposed for other major regional projects—and that the $600-million project remains on budget.
On the east platform, trains will arrive from Avenue Marie-Curie, letting passengers disembark before taking an elevator to departures.
On the west side, arriving travellers will access the platforms via the airport terminal, currently through the taxi gates.

Trains are expected every 6 to 10 minutes, each carrying over 500 passengers, with higher frequency during peak travel times in the afternoon.
The article describes a massive skylight framed by a central steel structure in the heart of the station stands dubbed “the Iceberg” by engineers (a nod to its shape). The station is said to be bright and airy, with extensive glazing and skylights, designed to feel spacious despite the limited footprint.
The remaining 15% of work is said to be the most challenging, referring to mechanical installations, lighting, and ventilation—the invisible systems crucial to smooth operation.
Meanwhile, ADM is also tripling the airport’s curbside capacity from six to 18 lanes to tackle congestion—a $10-billion project that includes new boarding gates, parking, and a “satellite pier” allowing more aircraft to dock externally.
In the short term, ongoing work is causing headaches for drivers, especially as the busy summer season approaches.
