Downtown Montréal

The REM arrives in downtown Montréal and will be connected to the three metro lines (orange, green and blue) in 2022-2023. Here are the information to better understand about work being carried out in your area.

Downtown sector

Central Station, McGill and Édouard-Montpetit stations 

You’ll be able to recognize the REM stations by the presence of glass and wood. Patterns on the paving stone and the stations’ outer envelope will also suggest movement. The stations are equipped with elevators and guidance paths to ensure the network’s universal accessibility.  

In the downtown sector, the colour white (for Central Station and McGill stations) and red (for Édouard-Montpetit station) are used for ceramics, street furniture and plantings around the stations. These colours represent the emblematic character of the city centre (white) and its urban aspect (red).

Work in progress

Completion of the station excavation and erection of the steel structure are underway at Édouard-Montpetit. On the McGill side, the construction of mechanical rooms and the excavation of the station’s platforms is in progress. Construction of the foundations will follow.  

The work at Central Station includes the installation of equipment (e.g. plumbing, electricity, ventilation, elevators, etc.), the creation of openings between platform level and street level, and the construction of the future central platform for the REM.

Southwest sector

Southbound overpass, Smith/De la Commune streets and Pointe-Saint-Charles 

Between Central Station and De la Commune Street, the REM will travel over the southbound overpass, the elevated railway structure linking the two. The REM will use the tracks on the west side, while the other tracks will continue to be used by exo, Via Rail and Amtrak. The Griffintown-Bernard-Landry station will be directly integrated into the southbound overpass, between William and Ottawa streets. 

Between De La Commune Street and the Lachine Canal, the REM will run on a structure located on the existing embankment along Smith Street.  

On the Pointe-Saint-Charles side, the REM will travel along an elevated structure. 

Griffintown-Bernard-Landry Station

This station, part of the reference project and which has been announced in June 2020, will be integrated into the Viaduc Sud, or “southbound overpass”, between Ottawa and William Streets in Griffintown. Learn more!

Work in progress

Repair work on the southbound overpass is being done and the replacement of the railway tracks on the west side is continuing. The widening of De la Commune bridge—at the corner of De la Commune and Smith streets—to create a dedicated REM track is continuing. Development work on the embankment along Smith Street also began, with excavation work and the construction of a pier. Installation of the drainage system and construction of the embankment retaining wall in this sector will follow. 

Construction of the elevated structure is continuing in Pointe-Saint-Charles.

Île-des-Sœurs and Samuel-De Champlain Bridge sector

The Île-des-Sœurs station is part of the “emblematic” section of the REM, characterized by the colour white.  It has a special architectural treatment because of its close proximity to the Samuel-De Champlain Bridge—its white colour and the vertical slats along the station are reminiscent of the design and the stays of this new bridge. 

A REM signature station

The Île-des-Soeurs station benefits from a special architectural treatment that echoes the design of the nearby Samuel-De Champlain Bridge.

Work in progress

Construction of the Île-des-Sœurs channel bridge and the elevated structure in this sector is advancing. Work is also continuing on concreting the Île-des-Sœurs station and preparing for the installation of the catenary rails and poles on the centre span of the Samuel-De Champlain 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. Located in Griffintown, between Ottawa and William streets, the station will be integrated into the Viaduc Sud, or “southbound overpass,” a structure that functions as a building supporting a rail bridge entering Central Station from the south.

Yes. The arrival of the REM will require the development of new access points for the REM station and a dedicated central platform, as well as modifications to meet the principles of universal access.


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.
