The Blue line of Montreal’s Metro system was temporarily shut down on Monday morning.
Service on the entire line, from Snowdon to St-Michel stations, was down due to the presence of smoke, according to the Société de transport de Montréal (STM).

The STM took to Twitter to announce the delay just before 7 a.m. Service is gradually resuming on the line.
The STM has dispatched shuttle buses between Snowdon and St-Michel to help passengers get around during the morning rush hour.
The shutdown comes after last Thursday’s Orange line shutdown, which lasted several hours.
