Staircase renovations

Starting July 26, 2021 we will begin renovations on some of the staircases.

One of the staircases leading from the street to the fare booth will be renovated. This will require us to turn off the escalator next to it for a period of 16 weeks. The escalator will remain open to customers but will not move. To facilitate customer flow during the work, the next escalator over will be set to go up. The elevator will remain operational at all times during the work.

Also, the four staircases leading from the mezzanine to the upper platforms will be replaced, one at a time, starting on August 9. Other nearby stairs will remain accessible. Each staircase will be closed for a period of about four to five weeks.

The station will remain open at all times during the work.

A new phase of work began in mid-July 2021, which allowed the reopening of Rollande-Danis-Pelletier Park, which surrounds Lionel-Groulx métro station. However, Greene Avenue remains closed to traffic between Delisle and Saint-Jacques streets during this phase of the project, which will focus on the west side of Greene Avenue.

The Greene Avenue bus stops which are currently relocated will therefore remain in the same temporary locations:

  • The 211 Bord-du-Lac and 425 Express Anse-à-l’Orme stops will be relocated onto Saint-Jacques Street just west of Greene Street.
  • The 405 Express Bord-du-Lac stop will be merged with the 78 Laurendeau stop on Saint-Jacques Street east of Greene Street.
  • The 485 Express Antoine-Faucon stop will be relocated onto Saint-Jacques Street just east of Atwater Avenue.
  • The 71 Du Centre stop will be relocated onto Delisle Street just east of Atwater Avenue.

Getting off the bus

To stay on schedule as much as possible, buses will let riders off on Saint-Jacques Street west of Greene Street. Riders will then have to walk about 200 metres to reach the Lionel-Groulx entrance building.

Riders cannot be let off closer to the station because buses would have to make a turn to get back to their pickup stops that would take several minutes, potentially more with traffic. This would result in late departures.

The bike shelter located in the park behind the stations’ entrance building reopened on June 18, 2021.

While Greene Avenue may now appear to be more accessible, for safety reasons it is important to avoid increasing traffic on this stretch, especially because of the prevalence of construction-related vehicles and trucks there.

Evening and night-time concrete work

We will be pouring concrete slabs in the upcoming weeks. The occasional work will involve concrete pouring during the day, followed by finishing work a few hours later.

How could the work affect you?

To ensure the proper installation of the concrete slabs, we will have to carry out the second phase of the work in the evening and early at night.  It is possible that the work will generate noise near the worksite.

This evening and night work will be occasional, and it will occur about ten times between now and mid-November 2021.

The first session will take place between 7 p.m. and 1 a.m. the night of September 23 to 24, 2021.

Additionnal work dates are as follow:

  • Septembre 30 to Octobre 1;
  • October 4 to October 5;
  • October 7 to October 8;
  • October 14 to October 15;
  • October 21 to October 22;
  • October 24 to October 25;
  • October 28 to October 29.

We are aware of the inconvenience this work may cause and are taking all necessary measures to reduce its impact on you. Rest assured that we have obtained all the necessary authorizations from the borough.

Pedestrians and bikes

Since mid-July 2021, Rollande-Danis-Pelletier Park, which surrounds Lionel-Groulx station, is reopened to the public. However, the bike path that runs through the park will continue to be rerouted since the area west of Greene Avenue will still be a worksite. The bike path will therefore remain on Delisle Street, between Atwater Avenue and Rose-de-Lima Street, until the work is completed. 

Located in the park east of Greene Avenue, the Premier-Chemin-de-fer pedestrian walkway is also now reopened.


Buses will not be running on Delisle Street in 2020 because Greene Street will be closed, so there will be less traffic for Delisle Street residents during the work. We expect an average of four trucks per hour. In 2021, about 65% of buses will start running again on Delisle Street.

We will have to block six parking spaces on Delisle Street and about five on Saint-Jacques Street during the work.

Some trees located within the worksite will be replanted elsewhere in the park, while others will have to be cut down. During project analysis, a comprehensive survey and forest engineer’s report were completed. Plans to compensate for canopy loss have been made in accordance with this report and following consultation with a City of Montréal agronomist. When the work is completed, we will have planted more trees than will have been cut down, improving the park’s canopy. Landscaping will also be done on site.

This refurbishment is needed to maintain the métro’s electrical power supply system, as the equipment currently in use has reached the end of its service life.

Refurbishing an electrical substation presents a unique challenge as the métro’s power supply cannot be cut off during the work. The equipment must remain in use to ensure uninterrupted métro service.

A public consultation was conducted about this project in 2017

An electrical substation houses the equipment needed to supply power to the métro network. There are seven electrical substations located across the STM métro network.

The project will mainly consist of constructing a new building where the Lionel-Groulx garage is currently located, between Greene Avenue and Rose-de-Lima Street. This garage houses the current electrical substation. The new building will house updated electrical equipment and a garage where maintenance vehicles will be stored.

We will also be replacing the waterproofing membrane that protects the station’s underground roof from leaks. This worksite will cover an area from the station’s main entrance building to the garage, located west of Greene Avenue.

No. The electrical equipment’s fans are equipped with powerful noise suppressors. Once the station is operational, the noise it emits will comply with municipal by-laws and will be no louder than current levels. In fact, it will be lower than normal conversation or the area’s usual ambient noise level.
