Impact on customer trips
Due to the start of construction on the new Pie-IX, Viau and Langelier métro stations, buses 141 and 372 have been rerouted onto Bélanger Street between 19th Avenue and Des Halles Street since October 28, 2024. A reserved lane has been set up on Bélanger to facilitate mobility during the work.

Impact on bus service - Lacordaire sector
- Bus stops for lines 32 and 353 at the intersection of Jean-Talon/Lacordaire are canceled.
- A temporary bus stop for line 32 northbound has been set up on Lacordaire, just north of du Mans Street.
- The 131 bus stops at the intersections of Jean-Talon/Lacordaire and Lacordaire/du Mans are canceled. The 131 bus stop at the corner of Antonio-Dagenais/Lespinay is also canceled.
- A temporary bus stop has been set up on Lacordaire, just north du Mans Street. This temporary stop is now the terminus and departure point for bus line 131 in this sector.
Impact on local residents
February 3, 2025 - Start of excavation work for the future metro station
Various preparatory work were carried out in the area since fall 2024, so that the excavation of the new métro station can then begin. That excavation phase started on February 3, resulting in some changes in local travel patterns. Part of Jean-Talon Street is completely closed to traffic east of the intersection with Lacordaire Boulevard.
Meanwhile, the work in the area inside Ladauversière Park continues for the excavation of an emergency exit of the future metro station.
Pedestrian traffic
- Sidewalks are closed along the worksite on the north side of Jean‑Talon Street and the east side of Lacordaire Boulevard. Walkways have been installed to allow pedestrians to get around the worksite safely.
Car traffic
- A section of Jean‑Talon Street is completely closed to traffic east of the intersection with Lacordaire Boulevard.
- Jean-Talon remains open to traffic both east and west of the worksite.
- On Lacordaire, one lane remains open in each direction along the worksite perimeter.
- Du Mans Street has become one-way westbound between Du Hautbois and Lacordaire.
Good to know
- Access to businesses and residences will be maintained at all times.
- Signage will be posted to direct pedestrians, cyclists and drivers.
- Worksite trucks will take Lacordaire, Jean‑Talon and Langelier.
- Appropriate mitigation measures will be put in place to reduce the impact on local residents, including noise walls around the worksite perimeter.
Join your local good neighbour committee!
Do you live near the future Lacordaire station or de la Villanelle auxiliary building and want to have your say in how the Lacordaire worksite will fit into your neighbourhood this winter?
A good neighbour committee will be set up in the coming months as a space for dialogue between the STM and the local community. We’re currently looking for people who live in the area to join the committee and represent local residents at a few meetings per year.
The committee’s purpose is to:
- Provide information and outline the different phases of the project.
- Start a dialogue between residents and project representatives that will continue throughout the work.
- Discuss how the impact of the work will be managed so that resident members can share this information with their local community.
- Understand the concerns residents have about the work and find solutions together.
- Allow local residents to make suggestions on specific topics chosen by the project office.
Write to us to apply or to find out more.

In the coming months, we’ll be starting excavation work to make way for new infrastructure for the Blue line project.
The excavation method will vary depending on the type of work being done. The surface excavation work will involve controlled microblasting, whereas most of the excavation for the underground tunnel will be done using a tunnel boring machine, or TBM. At both types of worksites, there will also be some mechanical excavation. The vibrations produced by the different excavation methods will be measured on an ongoing basis using seismographs. These devices will be installed at various points throughout the excavation zones and will be used to continuously monitor the vibration levels and make sure they fall within legal limits.
Essential preventive measures
To prepare for upcoming excavation work, the STM has tasked ABS with inspecting buildings that meet at least one of the following criteria:
- Located within 75 metres of any surface-level excavation work
- Located within 30 metres of the tunnel axis
The inspections will serve to compile an inventory of the structures surrounding the worksites for the Blue line project. The findings of the inspections will also be used to establish the maximum vibration levels for each site. Although these inspections are a precautionary measure, they are essential in the unlikely event that the work causes any damage.
As a further precaution, any building within 100 metres of a worksite where there will be microblasting will receive a carbon monoxide detector a few weeks before the excavation work starts.
Each building inspection lasts approximately 15 to 30 minutes. Photos are taken of the building interior and exterior. The photos are mostly close-ups of the foundations, walls, ceilings, and floors and serve to document the building’s condition prior to the start of the excavation work.
The pre-construction inspection is a common precautionary measure for major construction sites. It protects you in the unlikely event that your property suffers any damage during work on the Blue line project.
Controlled microblasting is used on several major STM worksites, depending on the type of rock to be excavated. To learn more, watch the video in the FAQ section of our Blue line project page.
In the fall of 2024 and 2025, urban forestry work will take place around the Blue line project worksites. Trees that interfere with the construction sites will be protected, replanted, or cut down. Our team of forest engineers, landscape architects, urban planners, and sustainable development experts has carefully planned these interventions to preserve as many trees as possible.
The goal is to replant the trees wherever possible. Soverdi, the not-for-profit organization overseeing the replanting process, will monitor and care for the trees after they are transplanted to ensure their survival. Trees that can’t be replanted due to their size or condition will be recycled into wood chips, firewood or compost depending on the quality of the wood. The health and species of the trees will also help determine which ones need to be cut down, based on whether they are diseased, subject to borer infestations, or invasive, among other factors.
On the Lacordaire site, some trees on the current worksite and in Ladauversière Park will be removed. In Ladauversière Park, Interventions remain limited, only a few trees will need to be removed, for the upcoming construction of an emergency exit for the future métro station.
Reforestation after the work
Ultimately, Blue line project sites will be revegetated and several hundred new trees planted, for a stronger, healthier canopy. For every tree replanted or cut down, we will plant more than two in their place.
The work involved relocating urban public utilities, giving us free rein to begin the massive excavation that will be needed to build the new métro station. The utilities that needed to be relocated included water pipes, sewers and underground conduits and cabling.
Before the preparatory work, the project team prepared informative video clips. Watch these clips to learn more about the project:

Yes. When we conduct the mass excavation to build the new métro station entrance building, the land will be decontaminated in compliance with current environmental standards.
Made up of citizens interested in representing their community, the purpose of the committee is to:
- Promote dialogue between citizens and the STM during the work
- Share information regarding the progress of the work and next steps with citizens
- Listen to the concerns of citizens during the work and find solutions together

The Blue line project follows in the wake of the Déclaration du gouvernement du Québec et de la Ville de Montréal to revitalize Montréal East. Many projects are underway to give a new impetus to this sector. Increased mobility, economic development, and improved living environments are at the heart of this ambitious project.
