Bus network redesign

Rethinking the bus network

Between now and 2026, a number of major public transit projects will be commissioned, including the REM, the Pie-IX BRT, the Blue line extension and the expansion of our fleet of buses with the addition of 300 vehicles. Deployment of these projects, along with urban development, will have an impact on how you use bus service. Now is therefore the ideal time to rethink the bus network to make it even more attractive and better adapted to changes on the Island of Montréal.

Let's do it together

The bus network redesign project is intended to be collaborative, we are rethinking it together.

What is the priority?

Close to 19,000 people took part in a survey aimed at measuring the importance of various factors related to the bus network architecture, such as walking distance to a bus stop, bus frequency, bus-to-bus transfers and trip time. The findings helped us identify your priorities. Find out more about this web consultation in the Project steps section below.

You want a frequent service.

Guiding principles

We will make service frequency the cornerstone of tomorrow’s bus network, with a view to making the network more attractive while maintaining accessibility for one and all. How will we do that? By following five guiding principles, to be applied differently depending on needs in the various parts of the city.

Promote frequent service

More buses and greater frequency will let you get where you want to go without advance planning.

Unlike personal vehicles, buses are available according to predetermined schedules and on specific routes. You therefore have to plan your trip. Higher bus frequency will reduce how long you have to wait at a bus stop and total trip time. If a high-frequency bus line is available at almost any time of day, that means no more need to consult schedules and plan ahead! Frequent service also mitigates the negative impact in the event of an incident. On a high-frequency line, if a bus is delayed or can’t make its planned trip, you can take another bus on the same line without having to wait very long.

Provide efficient transfers

Transfers with less waiting time, for a more comfortable trip.

Transfers are one of the main sources of frustration for public transit users. They can have a negative impact on your comfort and travel time. Transfers from one bus line to another are sometimes inevitable, as people leave from different starting points and their destinations vary. Seeing that transfers can’t be avoided, it is important to reduce waiting time as much as possible. How can we do this? By organizing the network so that as many transfers as possible are between high-frequency lines.

Prioritize direct, linear routes

This type of route makes it easier for you to understand the bus network, by helping you know where you are headed and making your trip more efficient.

Frequent service on a direct, linear bus line often means shorter travel time and more predictable service. On top of that, it is easy for us to enhance service on a linear route — for example, by providing express bus service as well as regular service during higher-ridership periods such as rush hours.

The right bus in the right place at the right time

Choice of vehicle adapted to ridership during a given period.

In addition to regular buses, we use articulated buses and shared taxibuses. On a typical day, the scope of the population’s needs in terms of mobility varies widely. In addition to adjusting the level of service, the STM could make better use of its array of available vehicles and, at times, even consider more frequent deployment of on-request service.

Maintain routes to neighborhood destinations

So all our customers have adequate access to the territory.

Bus frequency isn’t the answer to all needs. Local service is also required for full coverage of the territory and to meet travel needs within individual neighbourhoods. Local lines have different advantages than high-frequency lines: they minimize walking time, create links between different neighbourhoods and can connect isolated sectors.

In addition, aside of our bus network redesign project, we will look into how to improve service quality and comfort for seniors.

Let's chat about your needs

As each sector is different, we plan to hold consultations so you can voice your opinion and influence bus service in your sector.

We already have conducted several information sessions, 

Consultation sessions will be taking place in 2022

Information sessions held in 2020 & 2021

The virtual information session for the Lachine-LaSalle sector took place on October 28. See the results (French only)

The virtual information session for the Sud-Ouest, Verdun, Ville-Marie-Sud sector took place on November 17. See the results (French only)

The virtual information session for the Ville-Mont-Royal, Outremont, Côte-des-Neiges sector took place on November 24. See the results (French only)

The consultation for Saint-Laurent (residential area) and Ahuntsic-Cartierville took place on May 13, 2021. See the results (French only).
The consultation for Côte Saint-Luc, Hampstead, Montréal Ouest and Notre-Dame-de-Grâce  took place on December 6, 2021. Watch it and read the participants' ideas at parlons-en.stm.info

More consultation sessions will be taking place by 2025, in the lead-up to each consultation, residents of the concerned sector will receive information about the event and be invited to take part.


We have opted for a collaborative approach for the bus network redesign project. The main steps are listed below. We are currently at Phase III.

Workshops were held in summer 2018 with stakeholders from different areas:

  • environmental and public transit organizations
  • employer representatives
  • mobility and public health researchers and university professors
  • community
  • disabled community/universal accessibility

The STM presented proposals and gathered the participants’ feedback based on the specific situations of the groups they represented and their expertise. We thus confirmed the preliminary focus on rebalancing planning principles revolving around service performance (linearity, high-frequency service) and secondary-line coverage of the remainder of the territory.

An extensive online consultation called “Design a network to fit your priorities” was carried out last fall. The purpose of the web survey was to measure the relative importance of various aspects of the networks’ attractiveness for customers:

  • Walking distance to get to bus stop
  • Frequency of bus service
  • Presence or not of a bus-to-bus transfer
  • Duration of bus trip

Close to 19,000 people responded to the survey, allowing us to obtain a sample representative of all types of clientele.

Watch the video that we made for the web consultation to better understand the different options offered within the bus network’s architecture:

In parallel, discussion workshops were held with customers that could have had difficulties filling out the online survey to ensure all groups were represented: seniors, community and visually-impaired.

Main conclusion

For all types of users, the participants identified bus service frequency as the leading consideration, far ahead of the other priorities.

Eight to nine times out of ten, the participants placed greater priority on bus service frequency than on the other three aspects presented. We observed slight differences for certain types of users, but service frequency remained the number-one priority.

People with functional limitations, like the other groups, placed priority on service frequency.

Seniors gave top priority to frequency but were more concerned than the other groups by walking distance.

Residents of the east and west tips of the island gave top priority to frequency but were more concerned than the other groups by total trip time.

The higher the family income, the greater the priority placed on speedy trips.

The first sector consultation was held on Île-des-Sœurs in light of the first phase of the REM, which will arrive in 2022. A participatory workshop was held on April 24, 2019, during which residents and workers from the sector were invited to comment on various scenarios for developing the bus network. See the results.

Gradually, consultations will be held in other sectors of the Island of Montréal between now and 2025.

As consultations are held and the major public transit projects are commissioned, changes to the network will be deployed on a sector-by-sector basis.
