As the largest public transit project in the Greater Montréal area in the past 50 years, REM naturally raises many questions. These are the most frequently asked questions. Can’t find your question? Visit your Citizen Space or contact our team.

REM in service

The Autorité régionale de transport métropolitain (ARTM) develops rate schedules for all transit systems in the Greater Montréal area. We are currently working closely with the organization to integrate the REM into this future rate schedule.

The aim is to create a single fare. Customers would buy tickets from the ARTM that could be used in various networks, including the REM, the métro, buses, etc.

Our intention is that rates should be comparable to those currently paid for equivalent distances and that travel fares, for example the Opus cards, should provide access to both the REM and the other transit systems.

Frequency. The REM will be in service 20 hours a day, 7 days a week, with South Shore departures every 2.5 minutes during peak hours and every 5 minutes during off-peak hours.

Twice the capacity. REM will significantly increase the network’s capacity. Once it is completed, twice as many public transit customers will be able to cross the Champlain Bridge to Montréal.

Greater reliability for the trip home. Due to its reliability and dedicated corridor, REM will take you from downtown to: Panama Station in less than 10 minutes, Du Quartier Station in 13 minutes, Rive-Sud Terminal Station in 15 minutes. The congestion that buses leaving downtown currently have to deal with will be a thing of the past, replaced by reliable, fast and frequent service.

Connections to metro lines. REM will connect to Montréal’s three existing metro lines: the blue line via Édouard-Montpetit Station, the green line via McGill Station and the orange line via Bonaventure Station (Central Station). You will also be able to get to the Montréal-Trudeau Airport, Technoparc Montréal on the South Shore and the West Island.


Departure frequency. The REM will operate 20 hours a day, 7 days a week, with departures every 2 min 30 during peak hours and every 5 min in off-peak hours between Gare Centrale and Bois-Franc. Between Bois-Franc and Deux-Montages , trains will depart every 5 min during peak hours and every 15 min in off-peak hours.

Capacity. The capacity on the Deux-Montagnes line will increase significantly. For example, during morning peak hours between 6:00 a.m. and 9:00 a.m., the REM will serve 42,100 people (compared to 17,100 currently).

New connections. The REM will connect to Montréal’s three existing metro lines: blue (Édouard-Montpetit), green (McGill) and orange (Bonaventure). You will also be able to get to the Montréal-Trudeau Airport, Technoparc Montréal on the South Shore and the West Island.

Different cars. REM trains are not commuter trains; their cars are more like metro cars from a technological standpoint. REM cars are smaller but will run much more frequently, which explains the significant increase in capacity. The space will be designed for smooth passenger flow at transfer station entrances and exits (poles, bars, wider spaces). They will be air conditioned and equipped with bicycle and luggage racks.

Equipped stations. REM stations will be enclosed, covered, climate controlled and sheltered from the elements. You will  wait for the REM on a platform separated from the tracks by an automated screen door system (it will no longer be possible to drop objects on or to cross the track; safety and reliability will thus be improved). All stations will have elevators and be accessible to persons with reduced mobility.

The arrival of the REM means that users of the Mascouche line will have to transfer at a brand-new station (Correspondance A40) located just past Ahuntsic train station, if you are heading downtown.

The new Correspondance A40 station will be expressly designed to ensure smooth transfer of users between the Mascouche line and the REM. Station equipment will optimize traffic (wide corridors, elevators, shared platform, etc.).

As soon as you leave the commuter train, you will walk on a covered platform, then enter a closed station, sheltered from inclement weather. Once aboard the REM, the trip from Correspondance A40 Station to Central Station will take approximately 10 minutes. Total trip time to downtown for Mascouche line users will be equivalent to the current travel time.

The high frequency of the REM (2.5 minutes during rush hour) will mean fast boarding for users and reduced waiting times. Lastly, when heading downtown on the REM, you will be able to get off at new stations: Édouard-Montpetit, connected to the blue metro line, and McGill, connected to the green metro line. In the opposite direction, you will also be able to travel straight to the airport from this connection.

Community, works and schedule

Construction of the REM will begin in 2018. Mobilization of the construction sites, drilling, and relocation of public utilities will startin the first few months. In spring, a team of engineers and workers will set to work on opening the construction sites. They will focus on excavating, on preparing the REM’s future rights-of-way and on starting the infrastructure build (see the work calendar in 2018-2019) . Construction notices will be published ahead of time, to inform the citizens concerned.

For information specific to your region, subscribe to the notices of work by SMS (at the foot of the page) to monitor activities in your area and remember to visit your citizens' space regularly for more information.

Neighbourhood committees will soon be established. If you're interested and wish to be part of a committee in one of the five areas (South Shore, Downtown Montréal, North Central Montréal, Montréal West, North Shore), contact us. Throughout the construction period, information meetings and other events will be organized to keep citizens informed of progress.

  • Last departure Mascouche > Central Station: 5:17 p.m.

See alternate routes (RTM)


Starting June 25, 2018

A segment of the Deux­-Montagnes line will run along a single track in the Ville Mont‑Royal sector so that new stations can be built. The schedule for the Deux-Montagnes and Mascouche lines will have to be reorganized. 

New schedule on the Deux-Montagnes line
New schedule on the Mascouche line


Starting in early 2020

For approximately 24 months, the entire segment of the Deux‑Montagnes line between Du Ruisseau and Central Station will be replaced by a bus service (service will be maintained between Deux‑Montagnes and Du Ruisseau train stations). Alternative transit services will be presented in the fall of 2019.

Yes. The REM installation will entail platform and metro access changes, as well as renovations to provide universal access.

In addition to Central Station's current access to the metro, a new quick and direct connection to Place Bonaventure will be built for easier access from the REM station to Bonaventure Station. It will be universally accessible and equipped with elevators.


Connexions and access to stations

All REM stations and surrounding facilities will be designed for universal access. All stations will be equipped with elevators and some with escalators, and platforms will be level with the REM car doors.

You will be able to reach the REM stations by foot, bike, public transit or car. Check our interactive map to learn more about the services at your station (parking, drop-off area, bicycle racks, etc.):

Our primary intent is to focus on a sustainable solution: public and active transit. Bus networks in various municipalities will be revised to optimize feeder service to REM’s stations. The buses will stop near the stations for quick and efficient transfer to REM's metro cars. This cooperation with transit companies will continue throughout the project to ensure optimal feeder service as soon as REM starts up.

Yes. The REM will be connected to three Montréal métro lines: the orange line via Bonaventure station (Central Station), the blue line via Édouard-Montpetit station and the green line via McGill station.


The REM will run on the central deck of the new Champlain Bridge, replacing the reserved bus lane. The REM will access the bridge by running in the centre of Highway 10, between the two traffic lanes. At the bridge exit, it will stop at Nun's Island (Pointe Nord) and then continue on to downtown, crossing the Nun's Island channel via a new dedicated bridge.

The REM Chevrier station is not planned for phase one of the project.

Until the REM’s planned commissioning in 2021, the existing Chevrier terminus will continue to operate. During the construction of the right-of-way and infrastructure required for the REM to travel in the centre of Highway 10, new access ramps and reserved lanes for buses will be built so that public transit service in both directions remains efficient for riders on the South Shore. The access ramps will be constructed in 2018, and be in use starting in 2019.

After the REM is commissioned, the bus station and park-and-ride lot at the Chevrier site will be moved south of Highway 30, to the REM’s Rive-Sud terminal station. The agglomeration of Longueuil aims to keep the Chevrier sector as a transit-oriented development (TOD) area, and the objective is to provide public transport service for this sector, with a method to be determined. To travel downtown, riders in the Chevrier sector will be directed to the REM station that is closest to their departure point.

We need to define the location with the City of Montréal. This station is important for Montréal’s downtown neighbourhoods and the development projects that are under way. Because the profile of the route has changed and the station will now be an elevated, its plans require specialized consultation. Refer to the interactive map of the network to see the REM route in this sector.
