Lacordaire

Construction of the Lacordaire station

Construction site 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.


Next step

  • In 2025, excavation work will start.

Jean-Talon Street boasts new colours

Thanks to municipal funding, the Société de développement commercial de la rue Jean-Talon Est  joined forces with MU to beautify and enliven the street by creating a public artwork on a building owned by the STM.

Dan Buller’s artistic approach

The artist wanted to pay tribute to Saint-Léonard’s Italian heritage. Through the lens of Italian design movements, he reworked the Saint-Léonard and City of Montréal logos and the Montréal métro pictogram. He also drew inspiration from the 1976 Montréal Olympics graphics, which were characterized by bold compositions, large, flat shapes and bright colours.

Enhancing neighbourhoods near the project

The Blue line project team is happy to support this project by installing the artwork on a building owned by the STM. Other Blue line project initiatives aimed at enhancing the neighbourhoods where stations will be built include the Terrasse de Léon and the Prochaine station square, which are located where the future Lacordaire métro station will be.

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.

Get involved

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:

Clip 2: Mitigation measures (in French) on YouTube

Clip 3: Closures and mobility (in French) on YouTube

Clip 4: Community relations (in French) on YouTube

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.

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

Projects like the preparatory work in the Lacordaire area need to be planned months in advance. Together, our experienced technicians, engineers and project managers employ their knowledge of a variety of disciplines: civil engineering, structure, electricity, building mechanics, geotechnics, traffic maintenance and sustainable development, to name just a few.

Our design, project management and follow-up teams are putting their expertise to good use in the east end of the city, and all this is just the beginning!

The project in images


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.
