Centre and Airport

The REM will serve a total of five stations in the Saint-Laurent and Ahuntsic-Cartierville boroughs, one station in the Town of Mount Royal and one in the Côte-des-Neiges borough. Existing stations in the area will become REM light rail metro stations, and new destinations will be added, namely Côte-de-Liesse, Marie-Curie and YUL-Aéroport-Montréal-Trudeau. This information will give you a better understanding of the construction sites in your sector.

Centre Sector

Work in several REM construction sites has begun in the Town of Mount Royal, as well as in the Côte-des-Neiges, Saint-Laurent and Ahuntsic-Cartierville boroughs. Work in these sectors will advance as of spring 2020 with the acceleration of the construction of REM stations and the opening of new construction sites. 

Here are the stages of construction of the 6 stations on the central segment of the REM, in the Centre and Airport sector. These 6 stations are ground-level stations.

Work in progress


Rehabilitation and rebuilding of railway overpasses: Jean-Talon and Cornwall 

The closure of the Deux-Montagnes line as of May 11, 2020, presents a unique opportunity to access the railway track in order to repair and rebuild several railway overpasses. The Jean-Talon bridge and Cornwall bridge overpasses will be demolished and completely rebuilt by 2021, and the Henri-Bourassa overpass will be renovated and upgraded. 


Work in the railway right-of-way  

Between the future Canora and Du Ruisseau stations, several phases of work will follow one another until this segment is commissioned in order to reconfigure the track and the railway right-of-way to allow the passage of the REM.

Airport Sector

Marie-Curie and YUL-Aéroport-Montréal-Trudeau stations  

Between the Technoparc and Montréal-Trudeau Airport, the REM route will be underground to protect the wetlands in the Technoparc and to pass under the airport runways.  

The 3.5 km long and over 30-metre-deep tunnel will be drilled using an impressive machine: a tunnel boring machine nicknamed Alice, capable of both digging through rock and assembling the tunnel. This is the first time that a TBM of this type will be used in Québec. Drilling will begin in the summer of 2020! 

Marie-Curie Station

Marie-Curie Station

The Marie-Curie station will be located in the heart of the scientific park at the intersection of Alfred-Nobel Boulevard and Albert-Einstein Street. Learn more about the future Marie-Curie station, the last stop before the Montréal-Trudeau Airport.

Center and Airport

The work will generate noise, vibrations and dust. Dunkirk Road will be closed to traffic near the site’s logistics zone, between Jean-Talon Road West and Kirkfield Avenue. Kirkfield Avenue will remain open to local traffic to allow continued access to the L’Ombriè store.

We are aware of the inconvenience that this work may create close to educational institutions and in the heart of a residential area. All the necessary measures will be put in place to mitigate the impact on residents, including the installation of acoustic screens, the use of mist cannons to reduce dust at ground level and a close follow-up study of sound levels, air quality and vibrations.

For the commissioning phase of the project, we intend to maintain current sound levels and will take the necessary steps to keep noise impact to a minimum during the operations.

NouvLR, the consortium in charge of REM construction, is currently taking sound measurements all along the network in order to refine the models. Now that the consortiums for the construction and the rolling stock have been selected, we know which type of vehicle will be used and have a better understanding of how sound will travel in the REM’s right of way. The models being developed will serve to determine the mitigation measures to be put in place.

When assessing the noise impact of the REM, we must bear in mind the following:

  • The REM is a light rail transit system (LRT), which makes REM trains quieter than conventional trains.
  • REM trains will run more frequently but will have much shorter train sets (numbers of cars), meaning that it will take less time for them to pass by the area.
  • REM train cars will have quieter braking systems.
  • Mascouche line trains (which are louder than REM trains) will no longer travel past Mont-Royal station.
  • REM cars will be modern and quieter.
  • Because of the new A40 station, REM cars will travel through the area at a slower speed.

It is important to note that with the REM, a number of sources of railway noise will be reduced, particularly noise resulting from engine propulsion, aeration/cooling fans and the rubbing and squealing of the wheels on the tracks. Other sources of noise will be eliminated entirely, including disc brake rubbing, whistling on arrival at the station, and grade crossing alarms.

Possibly, it is too soon to confirm. Generally, the bus networks in various municipalities will be revised to optimize feeder service to REM’s stations. This cooperation with transit companies, including STM, will continue throughout the project to ensure optimal feeder service as soon as REM starts up.

The REM will pass every 10 to 15 minutes on the airport branch. From Central Station to the airport, it will take from 18 to 20 minutes with the REM express shuttles, which will be available during peak hours of the airport.

The REM will run in part on existing rail corridors. For safety reasons, level crossings will be eliminated. In places where level crossings currently exist, the road will be raised or lowered or the railway track will be elevated (the REM will run on an elevated track above the road).
