The Sûreté du Québec (SQ) police are investigating a pair of suspicious fires that ravaged two pizzerias within 20 minutes of each other in Salaberry-de-Valleyfield, Que., in the Montérégie region.

The first blaze started at around 3:20 a.m. Saturday in a restaurant on Maden Street, a largely residential road.

The other storefront sits on Hébert Boulevard, a main artery on the island community just west of Montreal.

No one was injured in the fire, though part of the mixed-use building was occupied by residents at the time.

SQ police spokesman Stéphane Tremblay says both buildings are a total loss.

He says the two fires are believed to be criminal and have been transferred to the arson unit.
