Autorité régionale
de transport métropolitain



When it was created, the Autorité régionale de transport métropolitain was entrusted with developing the Strategic development Plan (SDP) for public transit, paratransit and active transportation within the metropolitan area. The SDP will take into account the Communauté métropolitaine de Montréal’s Plan métropolitain d’aménagement et de développement (PMAD, or urban development plan) as well as the MRC Rivière-du-Nord’s outline for urban planning and development in the Ville de Saint-Jérôme area.

Toward the first public transit planning exercise for the metropolitan area

The SDP will unveil a vision of mobility development for the region until 2050—or for the next 30 years—and it will outline plans for public transit services and infrastructures over the next decade. The plan will also define the public transit facilities, infrastructures and services necessary to achieve this.

Want to know more about mobility in the region?

As part of this first general public transit planning exercise for the greater metropolitan area of Montréal and to prepare you for the public consultation that will take place this spring, ARTM experts have put together a wide range of information to keep you informed of mobility in the region.

This interactive platform was designed to provide us with common ground for dialogue that we would like to have with citizens of the region and people who use public transit, as well as fuel a SDP pilot project that will be the subject of a vast public consultation.

The plan will be implemented following this consultation, once required approvals have been obtained.

Join the conversation!

Whether you take part in the public consultation meetings, provide feedback on the sections of the site or submit a paper, citizens and partners in mobility are key to developing a successful SDP together.

Driving momentum for public transit in the metropolitan region while the groundwork for the SDP is laid

Mobility has experienced major growth, especially because of the development of public transit services. To sustain this momentum and bring together numerous projects together in the region that are already underway, the ARTM has developed a 2018-2011 Plan des initiatives de développement du transport collectif (PIDTC, or transit development plan in English). The PIDTC work will allow us to maintain the rhythm while the PSD is being elaborated and conduct studies that will provide input on how to implement it.

The ARTM has been listening closely and has been very proactive in developing this ambitious plan alongside its key partners; in other words, municipalities and the region’s public transit organizations. Underpinning this all is an open process and responsive governance that allows it to grow based on regional priorities.


  • Keeps track of public transportation activities being planned and implemented
  • Identifies new initiatives that can be rolled out in the short-term
  • Kicks off studies of major longer-term public transit projects

What is the ARTM?

Since June 2017, the Autorité régionale de transport métropolitain (ARTM) has been responsible for planning, organizing, funding and promoting the public transit, paratransit and active transportation services of the greater metropolitan area of Montréal to offer people an easy, integrated, seamless and efficient travel experience while promoting sustainable development and integration across the region.

It seeks to integrate services between different modes of transportation and works closely with public transit organizations. Exo, the Réseau de transport de Longueuil (RTL), the Société de transport de Laval (STL) and the Société de transport de Montréal (STM) are responsible for providing public transit services within their respective territories through agreements reached with the ARTM. By reducing the number of transportation organizations from 16 to 5, the new model, which is inspired by the best practices in Canada and around the world will allow us to make transportation in the region more efficient and coherent and offer clients a simplified experience.

Think about the environment!

In an effort to reduce paper and promote an environmentally-friendly approach, the ARTM will prioritize digital platforms in its communications with the public throughout the SDP.
