Metro service on Montreal’s Green line was halted early Thursday evening after emergency crews responded to an incident, but operations resumed later the same night. The interruption began on September 10, 2026, when emergency responders arrived at the scene, prompting the Société de transport de Montréal (STM) to suspend trains on the line as a safety precaution.
Emergency services, working in coordination with STM staff, managed the situation that caused the shutdown. Their intervention allowed the transit authority to assess conditions and ensure that the tracks and stations were safe for passenger use. Once the assessment was completed, STM announced that service on the Green line would be reinstated, and trains began running again shortly after the emergency crews cleared the area.
The brief outage affected commuters traveling on the Green line, a key component of Montreal’s subway network. While the exact nature of the incident was not disclosed, the rapid response by emergency personnel and the subsequent restoration of service underscored the coordinated efforts between city responders and the transit agency. The incident lasted only a short period, and normal service resumed without further disruption, allowing passengers to continue their journeys across the city.
