The arson squad is investigating what is being described as a suspicious fire in Montreal’s Ahuntsic-Cartierville borough.

The fire started inside a storage warehouse business located on Pontgravé Street, near Laurentien Boulevard at around 12:30 a.m. on Sunday.

Police said the fire triggered an alarm which alerted firefighters and activated the sprinkler system.

The blaze was quickly put out and damage to the building was limited.

Montreal police spokesperson Manuel Couture said the fire started just inside the front door of the business.

When firefighters arrived at the scene, they noticed that the glass door was shattered, raising the possibility the blaze was intentionally set.
