Centre and Airport

The REM will continue to serve the Town of Mount-Royal and the Saint-Laurent borough, as well as new destinations (Montréal-Trudeau Airport, Technoparc). Here are the information to better understand about work being carried out in your area.


The REM will gradually replace the Deux-Montagnes line in 2022 and 2023.

For the 2019–2020 period, the work will essentially involve the construction of new covered stations between Central Station and Du Ruisseau, requiring the closing of the Mount Royal railway tunnel and the complete interruption of commuter train service between these stations starting in January 2020.

The REM’s new stations will be located at the same place as the current stations of the same name. 


Canora and Mont-Royal stations

A new phase of work to build the Canora and Mont-Royal stations’ concrete structure began on May 21, 2019.

Over the coming months, work will be carried out on the south segment of the railway track in the following order:

  • The tracks and catenary will be removed and the eastbound track will be backfilled.

  • Pile driving work will allow the construction of the slope’s retaining wall.

  • The slope will be excavated in layers and the existing infrastructure (platforms and low walls) will be dismantled to clear the right-of-way for the construction of the future stations.

  • Drilling will then be undertaken to install the future stations’ foundation pillars.

To allow this work, the current platforms of the Canora and Mont-Royal stations were replaced by a shared platform between the two stations accessible via Canora Road. exo’s rail service has resumed on the westbound track of the right-of-way.

The construction of the stations’ metal structures and the rebuilding of the Jean-Talon and Cornwall bridges will begin during the complete interruption of rail service in January 2020.


Correspondance A40 station

Starting in 2022, the Mascouche line will be connected to the REM via the creation of a new intermodal station (Correspondance A40), which will be located north of Highway 40 along the railway right-of-way, between Stinson and Deslauriers streets, at the intersection of Hodge Street. 

Storage tracks* are under construction in preparation for the service interruption scheduled for January 2020 on the section between Central Station and Du Ruisseau station, to allow Mascouche trains to end their runs.  The preparatory work required for track installation and station construction includes relocating public utilities, putting up a utility building, constructing the foundations and installing the railway tracks, as well as backfilling and paving.

* In rail transport, a storage track is used to change train car order and direction.


Montpellier station

This summer, repair work will also be carried out under the railway structure of Côte-Vertu boulevard, near the existing Montpellier station, with no impact on rail service.


Bois-Franc station

In the coming months, preparatory work will be carried out to set up the construction site and to begin foundation work on the future station. New poles will be drilled in the centre of the railway track to transfer the power supply. The future station’s foundation piles will then be bored and anchored in the bedrock. Mass excavation beneath the existing rails will then create an underground walkway to connect both sides of the track. The station’s steel structure will gradually be put up by the end of the year.

Repair work will also take place under the railway structure of Grenet Street, near the existing Bois-Franc station, with no impact on rail service.


Technoparc and Montréal-Trudeau Airport stations

In the Technoparc area, the REM will gradually go underground to the north of Alexander-Fleming Street in order to avoid the wetlands to the south.

A few months ago, the construction of a trench began to create a transition towards the tunnel that will be excavated in the bedrock to connect the Technoparc and the airport. The work sequence involves the construction of the retaining walls, excavation to reach the level required to bore the tunnel, and steel framing work.

The boring of the airport tunnel will begin this fall; stay tuned for the arrival of our tunnel boring machine!

Work on the Deux-Montagnes line explained

The REM's work represent a major challenge in keeping the Deux-Montagnes and Mascouche lines in service until January 2020. We present the work in progress and the long-terme work schedule.


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.

In order to be able to continue work on the REM in the area where the future Canora and Mont-Royal Stations are being built, the stations’ platforms were replaced with a single, shared platform halfway between the old stations, accessible via Canora Road.

Furthermore, the electrical power supply had to be cut off upstream from the temporary Canora/Mont-Royal station, at the intersection of the Mascouche and Deux-Montagnes lines. Because of that, the Mascouche line’s dual-powered locomotives (diesel and electric) now must switch from diesel to electrical mode at the Canora/Mont-Royal temporary station, rather than at the Ahuntsic station, which increases the noise levels in the area.

Other noise you're hearing also relates to railway safety and train operation, such as customer messages broadcast on the speakers, grade crossing alarms, braking at station entry and acceleration at station exit.

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.
