Work underway at Atwater station

Project summary

By the spring of 2021, Atwater station’s waterproofing membrane will be completely refurbished. This major project requires the closure of De Maisonneuve Boulevard, between Atwater and Wood avenues.

We will take advantage of the excavation work to construct the shafts for the future elevators, which will link the mezzanine to the platforms.

Duration of the work: June 2019 to May 2021

Description of the work: Remplacement of the waterproofing membrane and installation of elevators

Métro impacts: No

Bus impacts: No

Impact on customer trips

The project will have no direct impact on customer trips.

Texte important

The station and its adjacent buildings will remain accessible at all time.

Impact on local residents

We are continuing the work initiated in spring 2019 to replace the waterproofing membrane of Atwater station’s underground roof and preparing to install elevators.


De Maisonneuve Boulevard will remain closed to vehicle traffic, between Atwater and Wood, until December 2020.

Coupe station Atwater

From May 11 to the end of 2020, the excavation zone will be moved in front of the De Maisonneuve entrance building, which will remain accessible at all times. Pedestrian and bike traffic will be modified to allow the work to continue.

Access to the métro station and its surroundings will be maintained at all times. A pedestrian path and bike lane also connect Atwater and Wood.

Learn more about the project

In recent years, the station’s interior and the De Maisonneuve and Sainte-Catherine entrance buildings were fully renovated. This project will put the finishing touches on the major refurbishment of the station before it becomes universally accessible.

Several steps have already been taken since the start of the membrane refurbishment work:

  • Excavation up to 7 metres deep, to above the métro track
  • Injection of existing cracks
  • Laying of membrane on initial part
  • Pouring of concrete on slopes
  • Sewer work on existing urban network

Excavating the ground above the station will allow us to carry out certain structural repairs inside the station and construct the shafts for the future elevators. This will avoid another road closure. We will install elevators in the shafts later.

Replacing a waterproofing membrane requires excavating the ground above it. We will dig one to four metres deep, depending on the locations. The station occupies the entire width of the boulevard underground. That is why we must close the boulevard completely to carry out the work. Minimizing the number of work phases enables us to reduce the total duration and cost of the work and increase its efficiency.

You will notice some worksite fencing and scaffolding but they will not impact your trips. We will reconfigure the mezzanine and platform areas for the construction of the elevator shafts. One business and several mechanical rooms will be relocated. The De Maisonneuve entrance building will remain accessible at all times.
