Service Disruption Details
The TTC stated that trains are not running between St. George and Union stations due to the smoke incident. Shuttle buses have been deployed to assist passengers, but significant delays are anticipated. Emergency crews are on site investigating the source of the smoke, which was first reported by station staff.
Commuters Advised to Plan Ahead
Passengers are urged to consider using the Yonge-University line or surface routes such as streetcars and buses. The TTC is working to restore service as quickly as possible, but no timeline has been provided.
