This project involves different phases: constructing a new building that will house a power station, replacing the waterproofing membrane covering the métro station’s underground roof, repairing the station’s staircases, and renovating the Lionel-Groulx rectifier station.
Description and duration of the work:
- Replacement of the Lionel-Groulx station waterproofing membrane: July 2020 to November 2020 (completed)
- Métro station staircase renovations: july 2021 to april, 2022 (completed)
- Refurbishment of the Lionel-Groulx rectifying station (exterior) : June 2022 to April 2023 (completed)
- Refurbishment of the electrical substation (exterior) : May 2020 to the end of 2023
Impact on métro: No.
Impact on bus: Yes, some stops will be relocated.
Impact on customer trips
The station will remain open at all times during the work.
Since September 5, 2023, bus stops of lines 71 South, 405 East, 405 West and 485 West are back to their original location on Greene Street.
Impact on local residents
Pedestrians and bikes
The bike path that runs through the park has been relocated since the area west of Greene Avenue is a construction site. The bike path is diverted on Delisle Street, between Atwater Avenue and Rose-de-Lima Street, until the work is completed.
Work on the west side of the power station
Landscaping work outside the Lionel-Groulx power station will be completed in spring 2024.
While Greene Avenue may appear 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.
Greene Street will be reopened to bus traffic as of September 5, 2023. Bus stops of lines 71 South, 405 East, 405 West and 485 West will be back to their original location.
Vehicle and bus traffic will stay the same on Delisle Street and we expect an average of four trucks per hour during the work.

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 several 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.

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.
This repair work aims to ensure the viability of the rectifier station and the reliability of the métro service. The work area is located southwest of Rollande-Danis-Pelletier Park.
What is a rectifier station?
A rectifier station holds equipment that is necessary to supply electrical power to the tracks in the métro. There are several rectifier stations spread out throughout the STM’s métro network.
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.
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.
In the interest of improving your trips, we need to carry out major repairs to the staircases of Lionel-Groulx station. This work will ensure the watertightness of the entrance building and the stairs to prevent damage from water infiltrations.
This work is needed to replace the entrance building slab and the staircase steps, which have reached the end of their useful life. To do this, we have to demolish the existing staircases, rebuild them, and then refurbish the granite surfaces.
The steps for this project are:
- Replace granite steps, landings and floor finishes.
- Improve the watertightness of structures.
- Install a waterproofing membrane and expand the trench drain.
- Replace the escalator frames.
