Pie-IX BRT project summary

The Pie-IX BRT is a bus rapid transit service designed to be comfortable, accessible and safe. It serves eastern Laval and crosses through four Montréal boroughs. The BRT also offers transfers to the métro Green line, commuter trains and a future Blue line extension métro station.

Buses use the reserved lanes seven days a week. This means that car traffic does not slow them down. They also get priority at traffic lights.

Building the BRT was also an opportunity to rethink the way Pie-IX was designed. The City of Montréal has upgraded the street’s sewer and water networks and widened the sidewalks, in addition to rebuilding the roads and medians along the BRT route.

Starting June 16, 2024:

  • Hochelaga will reopen to traffic in both directions on either side of Pie-IX.
  • Ontario will be closed to traffic in both directions on either side of Pie-IX. Work will begin on the east side once the west side goes car-free for the summer.
Texte important

Line 125 Ontario will be rerouted as of June 16, due to the work and summer pedestrianization. For more information about temporary detours and stops, visit the pedestrian streets page.

During summer 2024:

  • The east side of the Pie IX/De Rouen intersection will remain closed.
  • The east side of the Pie IX/La Fontaine intersection will remain closed.
  • The east side of the Pie-IX/Adam intersection will be closed at some point this summer.
  • The east side of the Pie-IX/Sainte-Catherine intersection will be closed towards the end of the summer when Ontario reopens.


General information

Work is scheduled to continue until 2027.

Work will run from 7 a.m. to 7 p.m. on weekdays. Evening and weekend work may be carried out as required.

Please note that any sign installation and road marking will be done at night to avoid blocking traffic. Residents will always be notified in advance.

Preparatory phase

  • Work at the Sainte‑Catherine and De Rouen intersections

Phase 1: February to December 2024

  • Major work on the east side of Pie‑IX Boulevard:
  • Excavation: CSEM, Bell and Energir
  • Surface work: sidewalk, median and road repairs
  • Setup of temporary lighting and traffic lights

Phase 2: 2025

  • Major work on the west side of Pie‑IX Boulevard (details to come).

Phase 3: 2026

  • Major work mid‑roadway (details to come).

Buses have been rerouted on Bourbonnière Street, northbound only, between Sainte‑Catherine and Hochelaga.

Stops 53296 (Pie-IX/Notre-Dame) and 53259 (Sainte‑Catherine/Jeanne‑D’Arc) are closed.

Map of the bus detour.

No detour Southbound.

Access to sidewalks or a pedestrian corridor will be maintained at all times on Pie-IX Boulevard.

Access to businesses and residences will be maintained at all times.

A two-way bike path was built on Bourbonnière Street.

The width of the Pie-IX Boulevard right-of-way makes it impossible to add a bike lane while maintaining reserved lanes, four traffic lanes and widened sidewalks. However, bike racks will be installed near the BRT shelters.

Traffic will be maintained in both directions throughout the work. Notices will be sent to residents to inform them of upcoming closures.

Traffic lanes will be narrowed in both directions between Sainte-Catherine and De Rouen Streets.

Some parking spaces located near work areas on Pie-IX Boulevard will be inaccessible between September 2023 and February 2024. All parking spaces on Pie-IX Boulevard will be removed starting in February 2024.

Some spaces for city parking permit holders will be relocated and new reserved parking zones have been designated on nearby streets for local residents.. If you have a parking permit for Pie-IX Boulevard, please contact the Mercier-Hochelaga-Maisonneuve borough for more information.

Depending on the progress of the work, temporary road blocks may be put in place occasionally around Pie-IX Boulevard.

Follow all posted signage!

Why are you extending the BRT?

Once completed, this project will benefit residents of the Mercier-Hochelaga-Maisonneuve borough and anyone who uses public transit in the area by providing faster, more reliable and safer bus service.

It will also upgrade the area’s public infrastructure and create a more attractive, user-friendly boulevard.

Description of the work

This project is being carried out in tandem with work by the City of Montréal. It will include:

  • Implementing 1.6 kilometres of reserved lanes
  • Building 6 new BRT shelters at the corners of four intersections
  • Replacing or refurbishing water and gas mains
  • Building new electrical infrastructure
  • Planting new trees
  • Implementing protective measures to ensure the safety of all
  • Repairing the road
  • Replacing street lighting and traffic lights
  • Widening the sidewalks
  • Fully redeveloping Pie-IX Boulevard, including new landscaping

Tree replanting

The plan is to plant more than two trees for each one cut down in the new space, while also diversifying the canopy with 12 different species. The new trees will be planted along the side of the road, making the area safer for pedestrians. In total, 230 trees will be replanted as part of the project, thereby increasing the street’s tree cover.

The felled trees will also be recycled by an organization that uses urban wood to make, for example, street furniture.

All project partners have acted in the interest of preserving as many healthy, mature trees as possible on Pie-IX Boulevard. Analyses were conducted with a specialized urban forestry company in collaboration with the borough. Additional studies were also conducted to find the best possible solutions before the start of the work. Consult the urban forestry experts' report (French only).

For more information on the trees, please see our FAQ.

Stay informed

Stay informed on the project's progress and other events by signing up to the electronic newsletter (French only).

Work is still underway on the east side of Pie-IX Boulevard. The phase scheduled to begin this summer will start on June 16, when Ontario Street closes to traffic and becomes car-free.


Starting June 16, 2024:

  • Hochelaga will reopen to traffic in both directions on either side of Pie-IX.
  • Ontario will be closed to traffic in both directions on either side of Pie-IX. Work will begin on the east side once the west side goes car-free for the summer.

During summer 2024:

  • The east side of the Pie IX/De Rouen intersection will remain closed.
  • The east side of the Pie IX/La Fontaine intersection will remain closed.
  • The east side of the Pie-IX/Adam intersection will be closed at some point this summer.
  • The east side of the Pie-IX/Sainte-Catherine intersection will be closed towards the end of the summer when Ontario reopens.

We understand the inconvenience these closures may cause and are taking all measures necessary to minimize the impact on traffic.


  • Police presence at intersections as needed
  • Pedestrian escorts at key times and busy locations
  • Traffic light reprogramming to improve traffic flow and make intersections safer
  • Additional signage and pavement markings:
  • Crosswalk markings will be maintained and improved (as needed depending on the condition of the intersections).
  • New signs will be put up (e.g., Desjardins bike lane, crosswalk at Morgan and Ontario).
  • A temporary crosswalk will be set up at Ontario and Desjardins.
  • Ongoing monitoring of changing behaviour and results
  • Regular follow-ups with local police

Please note that in the event of operational constraints or inclement weather, the work may be delayed or extended.

Major work on Pie-IX Boulevard is planned over the next few years, and any residential work and moving will have to be coordinated, as lanes will be blocked off.

If you are planning residential work or moving in 2023, 2024 or 2025 on Pie-IX Boulevard between Notre-Dame and Sherbrooke, please contact us as soon as possible.

Please provide the following information:

  • Your name
  • The expected date of your move or home renovation
  • Your address
  • Your phone number
  • Your e-mail address

We understand the inconvenience this work may cause and are taking all measures necessary to minimize its impact.


Street parking
Because of the worksite setup, vehicles will not be able to stop on Pie-IX Boulevard during the work.

We therefore recommend that you park on side streets or, if possible, on other streets near your home.

The Mercier–Hochelaga-Maisonneuve borough will be introducing new reserved parking zones for permit holders. To inquire about parking permit availability for residents of Pie-IX Boulevard, please contact the borough directly, online at https://montreal.ca/en/contact-city or by phone at 311.

Sidewalks and access
Pedestrian access to buildings will be maintained at all times. Sidewalks may occasionally be obstructed during certain operations. If this is the case, pedestrian walkways will be set up.

Garbage, recycling, organic waste and bulky items collection
Regular collection schedules will be maintained for the duration of the work. Residents within the work area must label their garbage and recycling bins with their addresses.

Bus service
Bus service on Pie-IX Boulevard will be maintained, but some stops may be relocated or closed. Bus detours will be in effect in 2024 and 2025. Read bus stop signs carefully and call 514-786-4636 or visit stm.info for more information.

Other notices are only available in French. Consult srbpieix.ca to read them.

Pedestrian tunnel (Jean-Talon area)

Shelters like no others

The Pie-IX BRT project included the construction of a pedestrian tunnel connecting the Pie-IX BRT to the future blue line extension station.

The construction of the staircase and tunnel is now completed. Work was carried below street level, in coordination with the blue line extension project office.

Next steps

In the coming weeks, glass panels will be installed in the SRB shelters located in the center of the roadway. Once this work is complete, buses on line 439 will return to the center of the tracks.

Work on the blue line extension will begin in the area in 2024.

Notices are only available in French. Consult srbpieix.ca to read them.


General questions about the project

The Pie-IX BRT shelters are spacious and comfortable. They are accessible to people with functional limitations and include electronic displays that show upcoming bus departures in real time.

Buses on the Pie-IX BRT will travel in the same direction as the traffic, at all times exclusively on a dedicated lane, generally in the middle of the boulevard. 

A number of protection measures have been integrated to ensure the safety of transit users and pedestrians, including the following: 

  • Reduced speed of traffic thanks to narrower lanes 
  • Elimination of all left turns unprotected by traffic lights 

Around the shelters, a variety of protection measures will be deployed:

  • BRT shelters are surrounded by short concrete walls with guardrails to protect transit users. 
  • Fencing installed across from the shelters will prevent people from crossing the road other than at intersections. 
  • At intersections with BRT stops, pedestrian crossing lights with digital and audio countdown and a call button have been installed at curbside and on the median at the shelter crossing, to help pedestrians cross. 
  • Emergency help stations have been installed in all shelters to maximize customer safety. 
  • Pedestrian crossings have been widened. 
  • The reserved lane is a different colour, to avoid confusion for car drivers. 
  • Although the BRT will not be in operation from 1:00 a.m. to 5:00 a.m., the reserved lanes will remain closed to other vehicles.

Yes. The BRT shelters are marked with strips of tactile paving in contrasting colours and slightly raised from street level by about 13 mm, making them easy to locate. Pedestrian crossing lights with digital and audio countdown and a call button have also been installed to help users cross Pie-IX Boulevard safely. Each stop also includes a wheelchair boarding area.

About the artwork

“Presented in pairs, the pieces appear as geometric variations inspired by the diamond emblem of the Pie-IX BRT project. […] The forms evoke both the sinuous twisting of a road and the constant movement that characterizes the comings and goings of public transit.” 

“As a symbolic reflection of the multiculturalism of public transit users, KYRIELLE seeks to honour the hybrid identities of Montréal and Laval and to revive a sense of pride, belonging and citizenship. The project is not only a vivid way to promote the new face of the Pie-IX BRT but also a chance to truly highlight the cultural diversity that drives both cities, while presenting a joyful, unifying vision of the street.” 

More information about the artist

Various electrification scenarios were analysed, first by the AMT in 2011 and then by the STM in 2013 and 2014.

Further to these studies, the scenario of an electric bus (or trolleybus) was not retained by the AMT, the City of Montréal or the STM, essentially due to very high costs, the impact of poles and overhead cables, and conflicts between the underground bases needed to support the power supply and municipal underground systems. The bases supporting the poles required for electrification are much larger than normal street light bases. In addition, there would be conflicts between these much larger bases and the roots of the numerous mature trees along the boulevard, the potable water main in the middle of the boulevard and certain sections of the sewer that have been retrofitted by the City of Montréal since 2011 in preparation for the Pie-IX BRT.

The City of Montréal and the ARTM have agreed to take advantage of implementation of the Pie-IX BRT to carry out municipal infrastructure work (roadwork and underground systems) that is needed due to the end of the systems’ useful lives and asset capacity limits.

Integration of municipal infrastructure work into the Pie-IX project has the following advantages:

  • Reduction of both partners’ costs by combining certain worksite expenses
  • Minimization of inconvenience for residents and users by carrying out all the work at the same time.


Jean-Talon area

This area took longer because both BRT shelters will include an elevator and a staircase to a pedestrian tunnel connecting the shelter to a future métro station on the Blue line extension. Building this infrastructure required more work than for the other BRT shelters. This work was done below street level, in coordination with the Blue line extension project office.

Integrating this tunnel into the Pie-IX BRT will allow us to work on the Blue line extension with minimal disruptions to traffic on Pie-IX.

Yes. Over the next few weeks, glass windows will be installed in the bus shelter at the corner of Pie-IX and Jean-Talon. The shelters will be opened once the installation is complete. In the meantime, line 439 will stop at the curb on Pie-IX, between Jean-Talon and Everett.

Later on, more glass panels will be installed on the métro side (the section leading to the pedestrian tunnel to the future Blue line extension station). The impact of this work has yet to be determined.

After that, a major worksite will be set up in the area to start on the Blue line extension. This work will not affect the routes of bus lines 139, 439 and 355.

Lines 139, 439 and 355 will remain on Pie-IX, between Laval and Pierre-De Coubertin. In winter 2024, detours will be implemented south of Pierre-De Coubertin due to work on the extension to Notre-Dame.

Lines 41, 141, 188 and 372 will again be diverted in the Jean-Talon area when work begins on the Blue line extension.

This is the area above the tunnel, staircase and elevator to the future Blue line extension station. This infrastructure is not open to the public because it doesn’t go anywhere—the station hasn’t even been built yet! This section of the BRT shelter will be opened when the new Blue line station opens.

We plan to install triple butterfly doors, one of which will be motorized, at the entrance to this section of the shelter.

We could not install the same art seen in the other BRT shelters at the Jean-Talon intersection because the shelters only have roofs over their waiting areas. This architectural choice was made to facilitate bus traffic. However, it meant that we could not install wall panels on these shelters. We are still looking into how best to integrate art into the shelters at this intersection.

Extension to Notre-Dame East Street

Since Pie-IX Boulevard is an essential artery for the Montréal economy, a full street closure was out of the question. As a result, the project is being implemented in phases to minimize the impact, with different sections closing for different phases (preparatory, east, west and centre).

The Notre-Dame Street extension also involves more extensive and complex development and infrastructure work, especially underground, than the previous projects.

Public transit:

  • Installation of 1.6 kilometres of permanent, two-way reserved lanes in the middle of Pie-IX Boulevard between Pierre-de Coubertin Avenue and Notre-Dame Street
  • Construction of four stops with seven BRT shelters (including one set-down only stop)
  • Installation of smart transportation systems in the BRT shelters (animated displays, cameras, etc.) and in the lanes themselves (priority measures at traffic lights and animated traffic display)

Municipal infrastructure:

  • Restoration and construction of sewers, water mains and urban public utilities
  • Reconstruction of the entire road system (foundation, road, sidewalks and median)

Street design:

  • Widening of sidewalks and addition of trees to improve local residents’ walking conditions and quality of life

Universal accessibility

We will maintain accessible detour routes. We will also have crossing guards stationed at more problematic intersections to help pedestrians cross Pie-IX Boulevard.

Trees and vegetation

Excavation near trees, no matter how shallow (a few tens of centimetres), is likely to have a major impact on their physiological survival, as well as on their short- and long-term stability.

In an effort to preserve as many healthy mature trees as possible, an analysis was conducted to determine what needed to be done with the existing vegetation, with the support of an urban forestry firm and in collaboration with the borough. We have also put the necessary effort and time (+ 1 year) before starting our work in order to carry out additional studies and find the best possible solutions.

The solution we found - to shift the boulevard slightly to the east - enabled us to reduce the number of trees to be cut from 144 to 107, or 25% less than originally planned. As a result, we managed to preserve 48% of the trees on Pie-IX.

Of these, note that about 10% had already been identified to be cut and the majority (approx. 60%) of the trees have no to medium conservation value, considering the excavation work that needs to be done near them.

Due to the size of the trees, they cannot be transplanted. The felled trees will be recycled by an organization specializing in the repurposing of urban wood.

Currently, most trees on Pie-IX are elms and maples. The project will plant around 12 different species, that were chosen to diversify the canopy.

The species were chosen for :

  • Speed of growth
  • Variety (to counter the effects of disease)
  • Ability to absorb water (on drainage pits)
  • Minimize impact on underground infrastructures and ensure better survival during future works

The new landscaping also offers a number of advantages:

  • Most of the new trees will be planted along the edge of the street, particularly on the east side, making pedestrian safer.
  • Trees along the roadside and in the middle of the road will help reduce heat islands.
  • Drainage pits are added for better water retention.
  • More than 2,300 plants will also be planted along Pie-IX.
  • 10 greened sidewalk projections
  • Street furniture: 15 benches, 18 litter garbage cans and 30 bike racks

At the end of the project, the canopy will have been bonified, as will the mobility experience of both pedestrians and public transit users, who will benefit greatly from the project.


Last year, we met with the two elementary schools, along with other institutions and businesses, to gain a full understanding of their needs and incorporate them into our plans. Most of the work will be carried out during the summer to minimize the impact on school operations.

The plan is to keep the drop-off areas where they are as long as possible, then move them to the street next to the school. Staff will also be on hand to guide the children safely to the new drop-off location.

Yes, emergency vehicle corridors will be in place during the work. We have also met with establishments in the area that receive large numbers of vehicles, such as ambulances, and plan to provide loading areas where needed.

Pie-IX remains an official truck route. An alternative route will also be set up to reduce through traffic there and divert vehicles to other major roads.

If we observe trucks repeatedly detouring onto local streets, we will take steps to correct the situation (this may involve added signage, police presence, etc.).

Drivers may prefer to use residential streets rather than Pie-IX during the work. We will monitor the situation closely and take the necessary steps to keep the neighbourhood safe and reduce through traffic on local streets as much as possible.

Bus service

Bus service is adjusted according to demand and ridership. As soon as the BRT went into service in November 2022, service was improved by 15% south of Pierre-De Coubertin. A further service upgrade is scheduled for January 2024.

Bourbonnière provides a direct route north and does not require any additional changes of direction or turns. It offers a compromise between walking distance and route efficiency.

Jeanne-D’Arc is the first street that goes south, so we chose it to minimize travel time for transit users.

Bus shelters had to be removed when they conflict with the work. However, they will be reinstalled as soon as possible, once the work is completed.

Local residents

The project office is currently repaving Bourbonnière in preparation for the bus detour in 2024. This will reduce the number of potholes and other imperfections in the pavement, limiting the disturbance caused by the bus traffic.

Waste collection: Schedules will be maintained. When your collection area is blocked, your waste will be removed by the contractor, who will be responsible for taking it to a drop-off point.

Moving, deliveries and emergency work: Please contact STM customer service. We will work to find a solution that meets your needs.

Snow removal: Snow removal on roads under construction will be managed by the contractor, and the borough will remain responsible for unobstructed areas, including sidewalks. When driveways are accessible—which will be most of the time—residents can clear them of snow as usual.

The situation will be dealt with on a case-by-case basis by an exterminator mandated by the project. If you notice the presence of vermin please contact customer service at 514 786-4636 or by filling out the the online form.

Parking lots on Pie-IX Boulevard will be removed during the work, as the configuration of the construction site makes it impossible to maintain them. Sticker zones will be relocated to adjacent streets by the borough.

After the work, there will be no parking on Pie-IX Boulevard. If you have any questions about parking stickers or parking, please contact the Mercier - Hochelaga-Maisonneuve borough.
