Station transformation


Get around

Replacing the waterproofing system requires us to dig into De Maisonneuve and Berri in order to reach the underground roof of the station. The scope and complexity of the project make it impossible to keep a lane open through the work zone.

The Métro station, businesses, restaurants and points of interest will be maintained at all times.

De Maisonneuve will be reopened in sections between May and July 2024.

Next steps:

  • April–May 2024: Reopening of the north sidewalk on De Maisonneuve between Saint‑Denis and Savoie, then between Savoie and Berri.
  • Late May 2024: Partial reopening of De Maisonneuve to car traffic.
  • June 2024: Partial reopening of the north sidewalk between Sanguinet and Berri.
  • July 2024: Full reopening between Sanguinet and Berri.

The escalator linking the Honoré-Beaugrand platform to the yellow line corridor will be closed from September 21, 2023 to April 2024, to allow installation of chilled water and fire protection pipes.



The Bibliothèque et archives nationales du Québec boarding point has been moved. Please refer to the information provided with your reservation for the exact boarding location.


The corner of Saint-Denis and De Maisonneuve will reopen to traffic on December 23, 2023.

Both sides of the intersection will be open to pedestrians.

Please note that the south sidewalk of De Maisonneuve between Sanguinet and Saint-Denis will be closed due to the relocation of the worksite. To access Berri-UQAM station and Saint-Denis Street, use the north sidewalk of De Maisonneuve.

Work outside the station

  • Replacement of the waterproofing membrane covering the station’s underground roof
  • Addition of a new pumping station and two water connections to improve the fire protection system

Work inside the station

  • Addition of two elevators on the Yellow line platforms
  • Refurbishment of the fire protection system
  • Replacement of the fire alarm system
  • Addition of a secondary distribution substation

Work on the entrance buildings

  • Upgrades to the natural ventilation shafts
  • Replacement of the chillers and water towers
  • Refurbishment of the Saint-Catherine Street entrance building’s outer envelope
  • 31,269 square metres: surface area of the station, equivalent to five football fields
  • 600+ STM employees working inside the station
  • 28 escalators
  • 5 public elevators in operation, and 1 private
  • 625 steps (more than double the number of Saint-Joseph’s Oratory)
  • 6 levels with 2 others housing mechanical rooms
  • 6 platforms plus connecting tracks
  • 5 entrance buildings
  • 28 metres deep, from the Yellow line platform to an exit (only Charlevoix station is deeper)
  • 13 shops inside the station

The Berri-UQAM interior renovation was a large-scale project composed of many complex operations, all with the goal of providing an enhanced customer experience. The station is now more user-friendly and welcoming than ever.

This was one of our network’s largest worksites in the last decade, and it was quite a challenge to keep the station open while completing such major work. Each operation and each implementation strategy was planned so as to minimize the impact on customers and on métro operations. Completing this project required us to manage equipment and materials in the station’s limited space and in a particular environment.

  • Summer 2010 to fall 2011: We removed the wall finishes in most of the station's public areas and replaced them with temporary coverings until the permanent finishes could be installed.
  • Winter 2012 to summer 2012: We completed the removal of wall finishes and dismantled the decorative red columns that no longer met today's standards.
  • Early 2013: We refurbished the station's main electrical conduits, which led to the temporary shutdown of several escalators.
  • 2013: We renovated the Berri and Place Dupuis entrance buildings, replacing the structural slab, ceilings, lighting fixtures, floor coverings and granite stairs.
  • From fall 2013 to fall 2014: we replaced part of the waterproofing membrane under Berri Street. This work was essential to protect the inside of the station
  • 2015: We completed the refurbishment of the Yellow line area of the station, with refurbished wall finishes and floor coverings and improved lighting. We also worked on the tunnel ceiling and rebuilt the walkway over the tracks.
  • 2016: We refurbished the Saint-Denis entrance building, reconfigured a few corridors to the Orange and Green line platforms and refurbished the staircase between these two levels.
  • 2015 to 2017: We focused the station’s transformation on the Green and Orange lines. These areas of the station are now brighter, more welcoming and more user-friendly.
  • From 2017 to 2021: We completed the Green and Orange line renovations. The mezzanine was completely renovated and we modernized the shop fronts, all the wall coverings, and the lighting, among other things.The spaces between the mezzanine and the Green and Orange lines are now brighter, and the nearby turnstile area has been rearranged for better customer flow.Two elevators now connect the Orange line to the Green line.

Did you know?

The refurbishment of the biggest métro station means:

  • 98,242 square feet of small round ceramic tiles installed
  • 4,700 lights changed
  • 2,649 ceiling tiles installed
  • 660 signage elements deployed
  • 3,000 linear feet of platform banners replaced


Due to the confined environment of the Yellow line, operations will be necessary outside of the current volume of the station.

In addition, the Yellow line platforms are located 28 metres below street level and installing elevators at that depth is a major technical challenge.

Since the Green and Yellow lines were not built directly on top of each other in the volume of the station, extending the newly installed Green line elevators down to the Yellow line was not possible.

The Berri-UQAM station will eventually have seven elevators allowing all customers to access its three métro lines.

Underground, the station is as wide as De Maisonneuve Boulevard West, between the Saint-Denis entrance building and the Place Dupuis entrance building. Under Berri Street, it begins 40 metres north of De Maisonneuve Boulevard and extends to Sainte-Catherine Street.

The scope and complexity of the work will make it impossible to keep a traffic lane open during certain stages of the work. Major work like this requires lots of space for moving machinery around. We will also have to deal with massive conduits (electrical power and others), which are particularly dense and complex and so, once again, we will need a lot of space to work around them.

We have been asked to replace the utilities located between the street and the station roof and in the excavation area. This includes water pipes, sewers and electrical duct banks. This means that this entire section of the street will be fully refurbished.

There are water pipes in the excavation area, so we may install a temporary water network. The outages would be short and only happen during the changeover. If this is the case, we will notify affected residents via the usual means of communication. If all goes according to plan, electrical networks should remain functional at all times.

Coordinating with the other worksites is very important to us. We have coordinated with the City of Montréal and the traffic plan was developed with all stakeholders in the area.

The waterproofing membrane protects the station from water infiltrations. It covers the station’s underground roof and is therefore located underground. The Berri-UQAM station’s membrane dates back to the station’s initial construction and has reached the end of its useful life.
