Fresh off the metro and bus strike this summer, the Société de transport de Montréal (STM) is facing another strike.
The STM plans to scale back service during a strike by its maintenance workers., meaning riders will face major cuts outside of peak hours.
The reduced schedule will remain in effect until October 5 unless a deal is reached beforehand.
When is the STM strike?
Starting September 22, 2025, there will be reduced metro service.
On Mondays, Wednesdays, and Fridays, trains will only operate during these three periods
- 6:30 AM to 9:30 AM
- 2:45 PM to 5:45 PM
- 11:00 PM until the last trains (around 1:15 AM)
The STM has posted last-train schedules in stations online here.
There will be no metro service between these periods.
On Tuesdays, Thursdays, Saturdays, and Sundays, the metro will run on its regular schedule.
Bus service will operate from 6:15 a.m. to 9:15 a.m., 3 p.m. to 6 p.m and 11:15 p.m. to 1:15 a.m.
Why is STM going on strike?
The Tribunal administratif du travail has defined which essential services must continue during the strike. Full metro service isn’t part of that list, which is why off-peak hours are being cut.
How long is the STM strike?
The strike is planned for three days per week from September 22, 2025, to October 5, 2025.
What does the STM strike mean for riders?
If you normally travel outside rush hours on a Monday, Wednesday, or Friday, expect significant disruption.
Night travel could be complicated—service doesn’t resume until 11:00 PM.
Last-train times will still appear on station screens and stm.info, so checking before heading out is a must.
