Downtown Montréal

The REM arrives in downtown Montréal and will be connected to the three metro lines (orange, green and blue) in 2022. Here are the information to better understand about work being carried out in your area.


Édouard-Montpetit station

The new station will be located in front of Université de Montréal’s Pavillon Marie-Victorin. The underground station will be 70 metres (20 storeys) below ground, making it the second deepest in North America.

Horizontal excavation of the station’s galleries will be completed in the winter of 2020. The station’s construction (structural work, concrete work and equipment installation) will then begin. Excavation of the station’s platforms will start in early spring 2020.


McGill station

McGill station will be beneath McGill College Avenue in the very heart of downtown, and will offer access to Montréal’s green metro line and its extensive underground shopping and restaurant network (RÉSO). It will also be connected to the Montréal Eaton Centre and Place Montréal Trust.

Excavation of McGill station and construction of the pedestrian tunnel linking the REM to McGill metro station will continue in the winter of 2020. Demolition of the Mont-Royal Tunnel arch, excavation of the platforms and construction of the station’s foundation will begin in the spring of 2020.

The work is carried out on De Maisonneuve Boulevard West (between Robert-Bourassa Boulevard and McGill College Avenue), and on McGill College Avenue (between De Maisonneuve Boulevard West and Sainte-Catherine Street West.


Central station

Preparatory work will be carried out in 2019 in order to schedule work for 2020. This preparation includes technical surveying, inspection and minor work.

Work on the technical and electrical rooms, as well as construction of the future station access will continue through the winter of 2020. Starting in the spring of 2020, major work will take place for the station’s construction, including the removal of existing railway infrastructure, demolition, installation of equipment and construction of the future central platform for the REM.


Southbound overpass

Ultimately, the REM will run over the southbound overpass and elevated railway structure leading to Central Station from De la Commune Street. REM will use the tracks on the west side, while the other tracks will still be used by exo, Via Rail and Amtrak.

Work to rehabilitate and repair that structure is in progress. Occasional projects will continue in 2020.

Work on the overpass to replace the railway tracks on the west side to accommodate the REM will begin in spring 2020. It will involve removing the catenaries, rails and ballast. Work at night will be required, to prevent disrupting rail traffic during the day.

Installation of the logistics area near the William Basin for this work will continue until late winter 2020.


De la Commune / Smith sector

Between the Lachine Canal and De La Commune Street, the REM will run on a structure that will be located on the slope along Smith Street, running parallel to the existing railway tracks. At De La Commune Street, it will run over the south overpass.

In early 2020, work to widen the De La Commune overpass will begin, to create a dedicated REM track. Work on the slope will also begin, with drainage work and construction of retaining walls and a pillar.


Bassin Peel

The Peel Basin station, which is part of the reference project, is planned for Griffintown, north of the Peel Basin. Technical studies are in progress to determine the exact location and conditions for constructing this station.


Lachine Canal area

Construction of the elevated structure that will cross the Lachine Canal is almost complete The railings will be installed shortly, and installation of the electrical system and tracks is set to begin soon.


Pointe-Saint-Charles sector

In this sector, the REM will be elevated and run alongside the existing Canadian National railroad tracks. Construction of the elevated structure progressed well in the Marc Cantin sector, and will continue on the rest of the route in Pointe-Saint-Charles in the next months.

South of the canal, an electrical substation will be installed and the beams and deck of the elevated structure will be installed by spring 2020.



Construction of the Île-des-Sœurs channel bridge and the elevated structure is underway. Work is also continuing on the station’s foundation.


Samuel-De Champlain bridge

Work is in progress to prepare for the installation of the track base and the catenary posts on the central span of the bridge.

Behind the scenes of Édouard-Montpetit worksite

After excavating the main shaft, the teams are starting a new step: digging the station’s galleries, at a depth of 56 to 70 metres.


Downtown Montréal

In February 2018, the REM route in the Griffintown and Pointe-Saint-Charles sectors was changed. The station will now be aerial (view the interactive map). This is an important station for Montréal’s downtown neighbourhoods and for the development projects that are happening in the area. We are currently finalizing the technical studies and will confirm the station location in consultation with the Ville de Montréal.

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.


The work will generate noise, vibrations and dust. The sidewalk will be closed in front of Pavillon Marie-Victorin, but no road closures are planned.

We are aware of the inconveniences that construction work can generate in a residential zone and near education and infant care institutions. All appropriate measures will be put in place to minimize impact on surrounding residents, including the use of acoustic screens and of a sprayer (fine droplets of water) to keep dust down, and a close monitoring of noise, air quality and vibrations.
