Navigating Montreal: A Comprehensive Guide to the Société de transport de Montréal (STM)
For residents and visitors alike, the Société de transport de Montréal (STM) is the backbone of urban mobility in Quebec’s largest city. As a public transport agency, the STM manages a sophisticated network of buses and rapid transit designed to move millions of people across the urban agglomeration of Montreal efficiently.
What is the STM?
The Société de transport de Montréal is the public agency responsible for operating transit bus and rapid transit services. Even as it has operated under various names since its origins in 1861—including the Montreal City Passenger Railway Company, CTM, CTCUM, and STCUM—the current STM entity was established in 2002.
Today, it operates the second most heavily used urban mass transit system in Canada, providing essential mobility services through a combination of metro lines, extensive bus routes, and specialized paratransit services.
The Transit Network: Metro and Bus
The STM’s infrastructure is divided into two primary modes of transport, ensuring coverage across the city’s diverse geography.
The Montreal Metro
The metro system is the core of Montreal’s rapid transit, consisting of four subway lines: Green, Orange, Yellow, and Blue. The network currently comprises 68 stations, with five additional stations under construction. The metro is designed for high-capacity movement and is a primary driver of the city’s daily ridership.
The Bus Network
To complement the metro, the STM operates a vast surface network that includes:
- 221 regular bus routes providing comprehensive daytime coverage.
- 23 night routes to ensure mobility after the metro closes.
- Taxibus and paratransit services for specialized accessibility needs.
Ridership and Impact
The scale of the STM’s operations is reflected in its massive ridership numbers. According to 2025 data, the agency saw an annual ridership of 520,606,200. On average weekdays in the fourth quarter of 2025, the system handled 1,618,100 daily riders.
Accessibility and User Services
The STM emphasizes inclusive mobility to ensure all citizens can navigate the city. Key services and features include:
- Accessibility Tools: The network provides wheelchair-accessible routes and buses equipped with front ramps.
- Payment Systems: The agency uses the OPUS card and other supports for fare management, with debit and credit card payment options available at metro booths.
- Digital Tools: Users can access real-time schedules, maps, and alerts via the official stm.info website.
