The REM will gradually replace the Deux-Montagnes line in 2022 and 2023.
As of March 30, 2020, the closure of the Mount Royal rail tunnel and the complete interruption of commuter train service between Central station and Du Ruisseau station will intensify work on this segment for building new REM stations. These will be located at the current locations of the stations of the same names.
Canora and Ville-de-Mont-Royal stations
During the fall and by the end of 2019, the work carried out at the future Canora and Mont-Royal stations mainly consists of finalizing the foundation work for the two new stations. Concrete work is ongoing that may require the use of night-time heating equipment to ensure that the concrete dries properly.
In 2020, a new phase of work will begin with:
the excavation of materials in the Mount Royal tunnel that will be transported by rail cars to the industrial sector of Côte-de-Liesse station for storage;
the construction of the metal structures of the two future stations;
the rehabilitation of the Jean-Talon street bridge to bring it up to standard, involving its closure in phases (duration: 2 years) to ensure its demolition and reconstruction, while maintaining a two-way traffic lane at all times;
the closure of the crossing at Lazard and Jasper intersection and the installation of a temporary pedestrian bridge.
From April 2020, the Cornwall avenue bridge will also be completely closed for 8 months for demolition and reconstruction.
Traffic is likely to be very difficult around future REM stations in 2020 due to the intensification of work in the area.
Starting in 2022, the Mascouche line will be connected to the REM via the creation of a new intermodal Côte-de-Liesse station, 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.
Work is progressing well in this sector; the construction of the exo platform and garage tracks* is well advanced and will allow the Mascouche trains to end from the commissioning of the REM network. 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.
Côte-Vertu et Marcel-Laurin railway viaducts
By the end of November, the relocation of public services and the rehabilitation of railway viaducts located respectively near Montpellier and Bois-Franc stations will be completed and motorists will find all the traffic lanes currently obstructed on Côte-Vertu and Marcel-Laurin boulevards.
By the end of 2019, work begun at the future Bois-Franc station is continuing so as to finalize the construction of the station's foundation elements, including elevator shafts, basement walls, foundation walls and slabs, and to erect the station's steel structure, which includes reinforcement, formwork and concrete work.
Work will also be carried out in the Bois-Franc station parking lot to allow the construction of a bus loop for the interruption of train service starting in March 2020. This work will result in the closure of 39 parking spaces and includes the construction of two new stairs, a user shelter, a bus ramp and the widening of the sidewalk.
Call for application for the Montpellier, Du Ruisseau and Bois-Franc neighbourhood committee in 2020. If you are interested, please complete the form by December 15, 2019.
Marie-Curie and YUL-Airport stations
In the Technoparc area, the REM will gradually enter a tunnel to protect the wetlands further south. The tunnel, which is 3.5 km long and over 30 metres deep, will be built between the Technoparc and the airport.
The tunnel will be drilled using an impressive tunnel boring machine (TBM) capable of both digging the rock and assembling the tunnel lining. This is the first time that a TBM of this type will be used in Québec. Due to its size (100 metres long), the TBM had to be delivered piece by piece, requiring around 60 trucks. Once all the parts have been assembled, tests will be conducted and drilling should begin in 2020.

Work on the Deux-Montagnes line explained
The REM's work represent a major challenge. 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’Ombrière.ca 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.
