Worksite summary
As part of the Blue line project, this worksite involves building a new accessible métro station with one entrance building. The entire extension is expected to be commissioned in 2031.
Please note that the station name is tentative.

Impact on local residents
Join your local good neighbour committee!
Do you live near the future Langelier station and want to have your say in how the Blue line project worksite will fit into your neighbourhood this fall?
A good neighbour committee will be set up in the coming weeks 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.
Upcoming excavation work
Full and partial street closures are planned at various points along the route and will last for varying lengths of time. Detailed planning is not yet available for your area. In the meantime, please see the Latest Updates and FAQ tabs on the project page for more information on the high-level planning.
Learn more about the project
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.
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:

We will keep you informed as the project progresses and let you know when construction will begin.
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.

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.
