The names of the five future stations finally revealed

The five names selected reflect a desire to celebrate the diversity, collective memory and shared values of Montreal and its métro system.

Breaking with the tradition of naming stations after adjacent roads, the names of the future stations on the Blue Line honour communities that have shaped the city’s history, while highlighting the decisive contribution of certain women to Quebec’s social, cultural and economic development.

The five names selected reflect a desire to celebrate the diversity, collective memory and shared values of Montreal and its metro system.

Since construction on the Blue line extension began in the fall of 2024, lines 141 and 372 have been diverted onto Bélanger Street, where a reserved lane has been set up.

To improve service in the area and offer a local alternative on Jean-Talon East Street, the 814 Jean-Talon Est / Bélanger bus shuttle will enter into service on July 7.

This new line will operate 7 days a week, between 7 a.m. and 10 p.m., approximately every 30 minutes. It will run mainly on Jean-Talon East and Bélanger streets, between Viau and Langelier Boulevard. This line provides access to several areas along Jean-Talon Street, while taking into account road segments that have closed due to the construction work.

A new service added in your area

This new line is in addition to several other bus options available in the area during the Blue line extension work, including lines 32 Lacordaire, 33 Langelier, 95 Bélanger, 136 Viau, 141 Jean-Talon Est and 439 Express Pie-IX.

Only a few months after the first site was started, excavation is now underway at all the new Blue Line station sites. This is a pivotal step in project delivery which requires rigorous planning, specialized technical skills and the mobilization of many stakeholders.

Work is also underway at three sites where auxiliary buildings will stand, marking a concrete step forward in the field.

The Pie-IX construction site. Visible is the access to the underground tunnel that will connect the future station to the Pie-IX BRT.

An impressive step

Because Montreal’s subsurface is essentially made up of very hard limestone, excavation is particularly difficult and inevitably noisy, especially for the first few weeks, when operations are closer to the surface. Measures have been taken at each site to limit nuisances, including the installation of noise abatement walls with rock wool acoustic insulation, white noise back-up alarm systems on trucks, and excavation techniques that reduce the use of jackhammers.

As excavation gets deeper, construction noise will be less noticeable on the surface.

Responsible management of excavated materials

Much of the rock extracted will be transported to the nearby Saint-Michel quarry. Saint-Michel quarry was chosen for strategic reasons—it’s a short trip for the trucks, which will reduce greenhouse gas emissions. It also leaves the rock near at hand so it can be reused for future municipal infrastructure projects to enhance sustainability.

We should also point that the work continues to be right on schedule. Other important milestones will be reached in the coming months, and we’ll provide regular updates as that happens.

Did you know...

The Blue Line extension tunnel will be nearly 8 km long, including the tail tracks and the underground train garage in Anjou. The depth of the tunnel will vary between 20 and 40 metres, depending on factors like the quality of the rock. Variations in depth are also designed into the route for efficiency purposes. The stations are usually shallower, to facilitate passenger access. That also provides for the train to be going uphill as it approaches a station, which helps it slow down and saves wear on the brakes. The train also gets a boost when it leaves the station, since it’s going downhill and needs less energy to speed up. Auxiliary buildings are located midway between the stations at greater depths where runoff tends to collect. They’re operational buildings with pumps to remove water from the network.

Microblasting excavation work will begin over the next few months on the Viau, Lacordaire and Langelier future stations sites and on the des Halles auxiliary building site. Consult the “Frequently asked questions - FAQ” tab for more information on this excavation method, or visit the page dedicated to each of these sites for information specific to your sector.


Construction of the Provencher auxiliary building will start this spring.

Preparatory work will start as soon as the contractor opens the site in the week of April 14 and will last for about four weeks. The work will involve putting up noise walls around the site perimeter and preparing the ground for excavation.

A public information session held. See the “Parlons-en” box for more information.

The construction work to build the des Halles auxiliary building will start on April 22, 2025. The first four weeks will involve preparatory work. After that, the final worksite zone will be set up on the Halles d’Anjou parking lot.

Future Lacordaire station : Start of excavation work on February 3, 2025

The preparatory work announced in fall 2024 for the Lacordaire area is now completed.

All of this work had to be done before we can begin excavating the main project site for the construction of the new Lacordaire métro station.

The excavation phase started on February 3, and requires the full closure of a section of Jean-Talon Street, east of Lacordaire Boulevard.

Viau and Langelier sites: Jean-Talon closed starting October 28

Work is going well at the Blue line project sites. Now that the preliminary work is done, we can set up the permanent worksite configuration and proceed with the excavation. This means that Jean-Talon Street will be closed to all traffic at the Viau and Langelier sites starting October 28, 2024.

  • The Viau worksite will extend from De Cannes Street to west of Viau Boulevard.
  • The Langelier worksite will be located just east of Langelier Boulevard.
  • North-south traffic will keep running as usual on Viau and Langelier.
  • Once Jean-Talon is fully closed on October 28, the bus stops for lines 141, 188 and 372 will be relocated to Bélanger Street. Visit the Modifications to bus service page for details.
  • A reserved lane has been set up on Bélanger to keep buses running more regularly during the work.
  • Roads will remain open to local traffic between worksites on Jean-Talon
  • Local businesses are still open and accessible.
  • Flaggers will be present at worksite entrances and exits for pedestrian safety.
  • North/south transit lines will be maintained
  • Access to homes will be maintained at all times
  • Bus routes will be adjusted as needed, and a reserved lane for buses will be added on Bélanger
  • Signage will be posted to direct pedestrians, cyclists and drivers
  • Paratransit service will continue to operate on Jean-Talon
  • The roads will remain like this for several years.

New reserved lane on Bélanger Street

A new reserved lane for buses, bikes and taxis will be introduced on Bélanger Street to improve traffic flow during Blue line extension work on Jean-Talon. Learn more about the modifications to bus commute.

  • September 25, 2024 : We are kicking things off for the excavation at the site of the future Pie-IX* station.  This work will result in the complete closure of rue Jean-Talon, east of boulevard Pie-IX.
  • Towards the end of October 2024, other complete closures of Jean-Talon street will take place in the Viau and Langelier sectors.
  • During 2025, other complete closures will be added on Jean-Talon street, notably in the Lacordaire sector. Partial road closures may also be required around the worksites.

This fall, construction will officially begin for the new stations in the Pie-IX, Viau and Langelier sectors. The work will involve full closures on Jean-Talon.

Several lots were purchased to build the future stations and infrastructure of the Blue line extension. Over the next few months, several buildings will be dismantled to secure the sites and prepare them for subsequent excavation.

The following will be dismantled over the coming months:

  • Two commercial buildings at Galeries d’Anjou, between Des Roseraies and Louis-H.-La Fontaine.
  • Two commercial buildings located East of highway 25, at the corner of Châteauneuf and Louis-H.-La Fontaine.
  • Former gas station building at the corner of Jean-Talon and Langelier.
  • West side of the commercial building on Jean-Talon, at the corner of De la Villanelle. Only the portion currently occupied by the convenience store will be removed. Nearby businesses will remain open.
  • West side of Le Boulevard shopping centre. The shopping centre will remain open during the dismantling.

Boots on the ground

Our accomplishments to date are a tangible sign of the project’s progress. The preparatory work that we have carried out in recent months includes moving underground infrastructure out of the way of the excavation sites for the future Langelier and Viau métro stations.

Geotechnical borings were also conducted at several locations to characterize the rock in the area where the new infrastructure will be built.

In addition, we demolished several buildings to make way for the new stations and operational infrastructure. The buildings were carefully dismantled, and their components were gradually sorted for recycling.

Community first

This year, the Blue line project team met with the public on several occasions. Our experts attended several conferences and held information sessions and good neighbour committee meetings to explain the work ahead and address people’s concerns.

Have you noticed the bright colours decorating the street at the corner of Jean-Talon and Lacordaire?

With the help of municipal funding, the Société de développement commercial de la rue Jean-Talon Est (SDC) teamed up with local arts organization MU to create a new piece of public art on an STM-owned building on Jean-Talon, breathing new life into the street.

Ready for worksites in 2024

There is no doubt that 2024 will be an important year. The stations’ architecture will be revealed, and major construction will begin. By the end of the winter, more buildings will be demolished to make way for future infrastructure that will benefit the entire community.

Preparatory work and building demolitions

Preparatory work in the Viau area is progressing as planned. In late May, work will end in some areas, freeing up more street parking. The work should be completed in fall 2023.

In late June, preparatory work will begin in the Langelier area. This will continue until the fall and require street closures at the intersection of Jean-Talon and Langelier. The work will be carried out in phases to reduce the impact on your travel.

We have also finished demolishing several buildings to make way for new stations and operational infrastructure. In a few weeks, we will also remove the buildings located at the site of the secondary entrance building of the future Pie-IX station. Once these sites have been secured, we will be completely ready to begin the excavation in 2024.

Le Boulevard shopping centre redesign project

In the next few months, measures will be implemented to ensure harmonious coexistence between Le Boulevard shopping centre and the future Blue line project worksite. Sections of the parking lot on the south and east sides of the building will be refurbished, including the area that was used as a snow disposal site last winter.

Public art beautifying the Blue line project

A few weeks ago, we revealed the five artists selected to make our new stations a visual delight for our customers. Do you know who they are? You can read more about each artist’s background and vision on the architecture and artworks tab of this page.


A major technological shift

In January, we launched a call for tenders for a complex and crucial project: the deployment of a new train control system on the Blue line and its future extension. Learn more about this cutting-edge technology and how it will change your transit experience for the better.


Preparatory work and building demolitions

Preparatory work in the Viau area has been on break for the winter and will resume in March with excavation on Baunard Street. Then, in early summer, more digging will be done in the Langelier area. The work will serve to relocate underground utilities (water pipes, sewers and cabling) to prepare the sites for the construction of future stations.

At the same time, we will be demolishing several buildings to make way for new stations and operational infrastructure. By the summer, the landscape will be quite different in the areas of Viau and Lacordaire, followed by Saint-Michel and Pie-IX (secondary entrance building). Once these sites have been secured, we will be completely ready to excavate!

Following efforts to optimize the Blue line extension, the locations of certain operational infrastructure have changed. The Anjou terminal station will have two entrance buildings to serve the areas located west and east of Highway 25. We reviewed the locations of the infrastructure needed to operate the métro in Anjou and created a final plan after studying several scenarios with the project partners.

Work in Anjou is currently expected to begin in 2024. Traditional excavation methods will be used east of Highway 25, as the tunnel boring machine will exit the ground west of the highway. Between now and the start of the work, surveys or drilling could be required to help engineers complete the plans and specifications. This work would be occasional and not very disruptive.

This month, we will begin preparatory work for the construction of the future Viau station. The work will first take place mainly on Viau Boulevard, where teams will demolish the central median. Then, all southbound lanes will be closed between Jean-Talon and De Paisley streets. Between now and fall 2023, this major work will allow us to relocate underground utilities (water, sewage and cabling) out of the way of the future station excavation site.

For full information on this worksite, check the web page for the future Viau station.

This is a first for the Montréal métro network. This construction method gets the work done faster, provides longer-lasting results and is better for the environment.

In due time, you will be invited to help us choose a name for the tunnel borer by voting on suggestions from our employees.

Following the expert committee’s work to optimize the project budget, some parameters have been revised.

Key details: 

  • Construction of all five new universally accessible stations up to Anjou as planned
  • Reconfiguration of the Pie-IX station bus terminal
  • Removal of lower-traffic secondary entrance buildings (Viau and Langelier)
  • Sharing of the planned secondary entrance building at Lacordaire station with CDPQ Infra to be integrated with the REM de l’Est.
  • Repositioning of the Anjou station with entrance buildings on each side of Highway 25.
  • Removal of park-and-ride lot in the Anjou area
  • Use of a tunnel boring machine to build the tunnel

Next steps: 

  • Preparatory work in the Viau area in summer 2022
  • Commissioning of the extension in 2029

In the spirit of agility and collaboration, every effort has been made to make this project the best that it can be and to bring us closer to this long-awaited asset for the east end of Montréal.

The STM is now the owner of Le Boulevard shopping centre, having completed the expropriation process started earlier in the project timeline. The mall will be able to remain in operation during the expected construction period of the new Pie-IX station.

This month, the second preparatory worksite for the extension of the Blue line will get up and running at the intersection of Jean-Talon Street and Lacordaire Boulevard. Between now and the spring of 2022, this major work will make it possible to relocate underground utilities (water, sewage and cabling) out of the way of the future station excavation site. Two other locations, namely Viau and Langelier, will undergo similar work later this year.

To learn all the details on this worksite, check the web page of the future Lacordaire station.

The chosen station names will go down in history as a mark of Montrealers’ collective imagination. They should be announced later this year.

The naming committee is composed of several STM representatives, a City of Montréal elected official, representatives from boroughs where the extension is being built and experts in place naming and urban planning. Montréal’s women, cultural communities and Indigenous peoples are also represented on the committee, and proposals from these groups will be given particular consideration.

The beginning of this process marks one more step toward the project’s completion!

In February and March, a public consultation process took place in the form of several information evenings and input sessions. The goal of this community dialogue was to design a project that would integrate seamlessly into the lives of Montrealers.

The Commission leading this process has submitted its report and issued 43 recommendations that will allow us to enrich the project and produce infrastructure that meets the expectations of our customers and citizens. Both the Commission’s report and the STM’s action plan in response to it are available at www.stm.info/consultation.

There’s no doubt about it—the Blue line project is right on track!

This is it!

This fall, we will begin preparatory work for the Blue line extension in the area around the future de la Villanelle auxiliary structure. This marks an important milestone in the project’s progress.

The work will mainly involve relocating urban public utilities, giving us free rein to begin the massive excavation that will be needed to build the new infrastructure.

Other target areas

In the next few months, we will also begin work in three other locations, near the future Viau, Lacordaire and Langelier stations. Information on these worksites will be available a few weeks before the start of the work.

The information evenings and input sessions are now closed. We would like to thank you warmly for your relevant and useful comments. This dialogue with the community is essential to helping us design a project that will integrate seamlessly into the lives of Montrealers.

The Commission’s report will be available at stm.info/consultation this summer.

Two new teams of architects have started working on the drawings for the buildings of the future Viau and Lacordaire stations. These complete the design brigade which started work at the end of 2019. An initial draft of the architectural design of these stations will be presented to the public in spring 2020.

Teams of architects have started working on the drawings for the buildings of the future Pie-IX, Langelier and Anjou stations. By the end of the year, two other groups of architects will join the design team and create Viau and Lacordaire stations. An initial draft of the architectural design of these stations will be presented to the public in spring 2020.

In addition to conducting ongoing above-ground seismic surveys and boring tests all along the Blue line extension route, we are collecting geotechnical data at Saint-Michel station.

Our teams will be conducting surveying work on the Saint-Michel tail tracks to gather highly detailed data on the existing tunnel and plan the connection to the new extented tunnel. As the heat released by the trains stationed on the tail tracks interferes with the accuracy of the laser instruments used for surveying, we will have to close the tail tracks on September 21 and 22.

Minor impact on your trips at this stationArrière-gare Saint-Michel

As trains will not be able to pull onto the tail tracks to turn around, customers going toward Snowdon will exceptionnally have to board on the exit platform. The train will then switch tracks when it departs toward Snowdon.

As part of the input data collection, geotechnical tests have begun along the corridor between Saint-Michel métro station and Highway 25 in Anjou.

The purpose of the tests is to classify soil and rock in the selected area in preparation for the construction of the underground tunnel and stations. The tests comprise two major phases, namely seismic surveys and boring tests.

1. Seismic surveys involve sending waves into the ground along a conducting wire connected to sensors. This non-intrusive, quick, one-time method limits the number of boring tests required for classification that will be conducted in a second phase of exploratory work.

2. Boring tests allow us to obtain more detailed data on soil and rock conditions, such as their resistance and profile. These characteristics serve as input data for the engineers who will design the plans and specifications.

The location where the tests are performed does not necessarily correspond to the locations of future métro stations or tunnels.


The current test involves extending lines over 40 to 70 metres, with sensors installed every 3 metres.


The cable is equipped with sensors that act as refraction wave receivers. The sensors are connected to the seismic line and slightly inserted into the ground or the road along the entire line.



The waves are sent into the ground every 10 metres by manually striking a 20-lb. (9-kg) sledgehammer against a steel plate on the ground. The plate and sledgehammer are connected to the seismic cable, sensors and receivers. The plate is struck several times to ensure that the waves are effectively transmitted all along the seismic line.


The geophysical technician measures the wave refraction data directly on site and ensures that the signals are clear. Subsequent interpretation of the data will help identify the characteristics of the rock.



A drilling rig is used to extract rock cores up to 60 metres underground, below tunnel level.


First, the road is cored for boring to take place. The operation is repeated at regular intervals along the six-kilometre route. The area will be restored after the tests have been completed.



Samples are taken either vertically or diagonally from the soil and rock, depending on the data sought by the geologists.


The soil samples collected are then analyzed in a laboratory to identify their properties and characteristics.


The blue line extension 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.
