Montreal Commuters Brace for Disruptions as Full STM Strike Schedule and Reduced Service Hours Confirmed

Montreal commuters are facing major transit disruptions after the stm strike schedule was officially confirmed by the Société de transport de Montréal (STM). The labour dispute, led by maintenance employees under the Confédération des syndicats nationaux (CSN), will run from September 22 to October 5, 2025. This stm greve marks the second major work stoppage this year and is expected to affect thousands of daily riders across the bus, metro, and paratransit systems.

STM Strike Dates and Context

• Strike period: September 22 – October 5, 2025

• Days affected: Mondays, Wednesdays, and Fridays

• Union demands: 25% wage increase, opposition to outsourcing

• STM offer: 12.5% raise over five years

Union representatives argue that inflation and living costs have eroded wages, while STM management insists that higher demands would force service cuts or require additional taxpayer funding.

This stm strike follows an earlier stoppage in June 2025, signaling heightened tensions between workers and management.

Reduced Service Days

During the stm greve, transit service will be reduced on three key weekdays each week:

This alternating schedule ensures some service continuity, but commuters should expect longer travel times and overcrowding.

STM Metro Schedule During Strike

On Mondays, Wednesdays, and Fridays, the metro system will operate in limited time windows:

• Morning: 6:30 a.m. – 9:30 a.m.

• Afternoon: 2:45 p.m. – 5:45 p.m.

• Evening: 11:00 p.m. – closing time

All other hours on reduced days will see stations locked and no trains in operation. Riders planning late-night or early-morning trips should prepare alternative options.

STM Bus Schedule Adjustments

Bus services will follow a similarly restricted timetable on strike days:

• Service paused: 1:15 a.m. – 6:15 a.m.

• Morning service: 6:15 a.m. – 9:15 a.m.

• Paused again: 9:15 a.m. – 3:00 p.m.

• Afternoon service: 3:00 p.m. – 6:00 p.m.

• Evening gap: 6:00 p.m. – 11:15 p.m.

• Night service resumes: 11:15 p.m. – 1:15 a.m.

This timetable affects not only regular routes but also school bus services.

Paratransit Service Remains Stable

Unlike bus and metro services, paratransit will remain unaffected by the stm greve. This guarantees continuous accessibility for riders with mobility needs, an essential service for many Montreal residents.

Impact on Commuters

The stm strike schedule has significant implications for daily life in the city:

• Students and workers may face long commutes and must plan around restricted service windows.

• Traffic congestion is expected to rise as more residents turn to cars, ride-sharing, and taxis.

• Events and nightlife could be heavily disrupted since many concerts and games overlap with non-service hours.

Educational institutions such as McGill University have already advised students to allow for delays and consider remote or flexible arrangements.

Greve STM Negotiations and Outlook

With no agreement yet, the greve stm could extend beyond October 5 if talks stall. STM leadership warns of financial strain if union demands are met, while union leaders emphasize fair wages and resistance to subcontracting.

Both sides remain under public scrutiny, with Montreal residents closely following this latest stm greve through local montreal news updates.

If no resolution emerges, commuters may face more uncertainty and additional transit interruptions later in the year.

The stm strike is a defining moment for public transit in Montreal, balancing worker demands against financial sustainability. For now, the stm strike schedule offers clarity on when buses and metros will operate, but residents must prepare for ongoing disruption. Montrealers will continue to rely on timely updates as this critical labour dispute unfolds.
