Montreal's fire department has extinguished a fire that broke out at the Lionel-Groulx metro station on Saturday.

Authorities said the fire was started when some paper fell on the tracks.

The STM has confirmed that service is back to normal.

Earlier in the day, service on several lines was interrupted and Lionel-Groulx was evacuated.

The station is a major transfer point for passengers switching between the orange and green lines.
