Work began to install elevators at D’Iberville station as part of a project to make it universally accessible. The station will also undergo major renovations on its main entrance building.
Duration of the work: October 19, 2020 to spring 2023
Description of the work: Elevator installation, major renovations on main entrance building
Métro impacts: The main entrance building is closed for the entire duration of the work. The secondary entrance is opened.
Bus impacts: Some bus stops are closed and relocated.
Impact on customer trips
Closure of main entrance building
The entrance building at D’Iberville and Jean-Talon is closed since October 19, 2020 until the end of work, which is planned for spring 2023. In spring 2020, we rearranged the turnstiles and fare booth in the secondary entrance building so that it could accommodate additional customers.
Impact on the station
Partitions are installed on the platforms and in some areas inside the station, but they will not affect customer trips.
Relocated bus stops
Making your trips easier
A stop for the 93 Jean-Talon will be added at the corner of Jean-Talon and Des Écores to serve the entrance building that will remain open throughout the work.
Impact on local residents
We will be working on some Saturdays, between 9 a.m. and 5 p.m. Saturday. During the week, work hours will be extended to 8 p.m. at the latest. This schedule is authorized by municipal by-laws.
Excavation at the worksite is progressing well and nearly complete. Two of the three elevator shafts have been fully dug out, and the third is 85% excavated. This means that this step will be finished in early summer.
Excavation work started in mid-January. This stage of the work will cause noise and vibrations that local residents may notice. The following mitigation measures will be in place:
- Noise walls have been installed around the worksite to reduce noise levels.
- Seismographs have been installed in strategic locations to monitor vibrations and prevent any damage to infrastructure.
- Sound levels are measured to ensure that they do not exceed permitted thresholds.
- The work is conducted Monday to Friday, between 7 a.m. and 8 p.m., in accordance with municipal by-laws.
Based on the current schedule, excavation will continue until summer 2022. However, as the work progresses, different digging equipment will be used, which will reduce the noise and vibrations.
Could buildings near the worksite be damaged during the excavation work?
The required excavation work will generate vibrations that may be felt by residents near the worksite. We have hired an independent consulting firm to survey (mainly photograph) all buildings around the worksite and to monitor the vibrations generated by the work using special equipment. These inspections will document the condition of the buildings before and after construction. In the unlikely event that any damage is reported, an expert opinion could help to determine whether the damage is the result of the vibrations produced by the work site. Property owners affected by this measure have been notified accordingly.
Exterior work will be divided into two phases, each corresponding to a different worksite layout.The worksite will have the following impacts on traffic:
Phase 1: from November 25th, 2020 until September 2022.
D’Iberville Street will be closed completely in front of the main entrance building and on the south side of the intersection with Jean-Talon. Jean-Talon Street will be partially blocked. Westbound traffic will be diverted into one of the eastbound lanes.
Phase 2: from September 2022 until the end of the work.
D’Iberville Street will be reopened with one lane in each direction. The roadblock on Jean-Talon will be reduced and only take up the parking lane, restoring four-lane traffic on Jean-Talon.
Why do we have to block the road?
The elevators will be installed inside the station. However, in order to install the ones that will connect the mezzanine level to each of the platforms, we have to dig into the métro tunnel, which is located underneath Jean-Talon Street. This is why two different worksites will be set up on either side of Jean-Talon.
Due to roadblocks, the 94 D’Iberville will detour onto Écores Street and Louis-Hébert Street. We recognize the impact that this will have on residents of these streets. Rest assured that we will do everything possible to minimize inconveniences to your daily life.
The work will be done in compliance with all municipal by-laws.
Work will take place mainly during the day, but some operations may need to be conducted at night while the métro is not in use, or on weekends.
In accordance with municipal by-laws, any construction work likely to generate noise will generally be scheduled between 7 a.m. and 8 p.m.
We are taking all measures necessary to remain within the noise limits set by municipal by-laws for all work taking place during the weekday, on the weekend and at night.
Anti-dust sheets will be installed on all the worksite partitions to limit dust dispersal.

D’Iberville station was created by architects Paul Brassard and Walter Warren, who had already designed Saint-Laurent station two decades earlier.
Both the station and the street get their name from Pierre Le Moyne, Sieur d’Iberville (1661-1706), who founded Louisiana and is known as the hero of New France.

Three separate excavation areas have been set up around the main entrance building, at the corner of Jean-Talon and D’Iberville. Each area corresponds to the location of one of the elevators. Wondering why we have to dig into the street, when the elevators will be located inside the station? Well, to install the two elevators that will connect the mezzanine level to each of the platforms, we have to dig into the métro tunnel, which is located underneath Jean-Talon Street
In the two sites that connect to the platforms, we have to dig to a depth of about 16 metres underground. Before hitting the bedrock layer, we have to install retaining walls to keep the soil from collapsing in. We then use mechanical equipment to fracture the bedrock.
The metal structure can support over 30 tonnes of weight! During the excavation, it holds all the duct banks (conduits for electricity and telecommunications lines) that are normally buried underground. These conduits are placed in wooden cases and strapped securely to the metal structure. This keeps them out of the way while we dig.
The interior of the main entrance building is unrecognizable! There’s plenty of work to be done: enlarging the entrance to install one of the elevators, demolishing and rebuilding the structural slab, installing new floor finishes, redoing the roof, building a natural ventilation shaft and, finally, building a new fare booth. Of course, this work cannot be done while customers are using the entrance building, which is why it is closed during the project.
This photo shows the platform wall; the tracks are on the other side of the wooden partition. We have installed a beam to support the structure during the excavation.

The Accessibility program is made possible thanks to the additional funding announced by the federal and provincial governments to speed up universal accessibility work with the goal of having 30 accessible métro stations by 2025.
