The Autorité régionale de transport métropolitain (ARTM) is the public authority responsible for financing, planning, organizing, developing, and promoting collective transport in the Montréal metropolitan region. It oversees metropolitan funding mechanisms and major transit investment planning. View Autorité régionale de transport métropolitain (ARTM)'s website for more information.

The Autorité régionale de transport métropolitain is the metropolitan public authority responsible for financing collective transport in Greater Montréal. Its website shows that it does more than coordinate transit policy: it helps structure the financial model that supports operations, infrastructure, and major mobility projects across the region.
The ARTM describes its mandate as planning, organizing, financing, developing, and promoting collective transport. It also publishes corporate documents such as annual reports, budgets, and a 10-year capital investment program, which reflects a formal role in public infrastructure funding and accountability.
The financing pages identify several sources used to support the metropolitan transit system, including government subsidies, municipal contributions, user fares, vehicle registration taxes, and other revenues. The site also explains transport redevances tied to major projects such as the REM and the blue line extension, showing how the ARTM uses project-based funding tools to support transit development.
Created by the Government of Québec in 2017, the ARTM serves the Montréal metropolitan territory, including Montréal, Laval, Longueuil, Kahnawake, and Saint-Jérôme. Its funding role is tied to the broader governance of transit across this region, with a focus on long-term financial stability, integration of services, and support for major mobility infrastructure.
The organization’s governance structure includes a board and coordination with the Government of Québec and the Communauté métropolitaine de Montréal. Its public documents and financing pages provide evidence of an official, continuing responsibility for managing and allocating transit-related funds at the metropolitan level.
