With the Canadian Grand Prix coming to Montreal, the city will be busier than ever—with a week-long metro and bus strike in the mix.
Maintenance workers at Montreal’s public transit agency are set to strike this month, causing disruptions to bus and Metro service outside of rush hours.
Time Out Tip: No better time to mention that over 7 km of road across six boroughs will be officially car-free for nearly four months from June to September, 2025.
According to Quebec’s labour tribunal, Société de transport de Montréal (STM) employees are permitted to strike from 12 a.m. on June 9 to 11:59 p.m. on June 17, 2025.
During this period, only essential services will be maintained during peak hours and late evenings.
There will be extended service periods on June 12, 2025, and full service over Canadian Grand Prix weekend from June 13 to June 15, 2025.

When will the bus and metro run during the STM strike?
STM service will be limited to rush hour and late evenings on June 9, 10, 11, 16 and 17, 2025:

Why is the STM going on strike?
Members of the local Canadian Union of Public Employees (CUPE) stated that the STM administration continues to make significant demands on unionized staff, particularly when it comes to work schedules, work-life balance and job security.
Also among the points of contention between union members and the employer is the issue of wage increases and the privatization of paratransit services.
