Authorities are investigating for possible arson after a fire tore through an abandoned two-story commercial building on Cure-Labelle Blvd. in Laval early Saturday morning.

Authorities were alerted at around 1:30 a.m. by a passerby. 

28 firefighters were deployed to the scene.

The fire is estimated to have caused between $350,000 and $400,000 of damage.

The two-alarm fire resulted in the temporary closure of the Cartierville Bridge connecting Montreal and the Laval neighbourhood of Chomedy.

There were no injuries in the fire.
