MONTREAL -- The SQ has opened an investigation into two suspicious fires that ravaged pizzerias, about 20 minutes apart, in Salaberry-de-Valleyfield, in Montérégie.

The first fire started around 3:20 a.m. Saturday in a restaurant on Maden St. The building is a total loss, according to SQ spokesperson Stéphane Tremblay.

The other store destroyed by a blaze is located on Hébert Blvd. The location is a commercial and residential building, two units of which were occupied at the time of the event.

Fortunately, no one was injured, but the victims will have to find a new home since the building is also a total loss.

Firefighters transferred the two investigations to the provincial police, which assigned a fire scene technician to the file.

Tremblay said the two fires were believed to be criminal acts, but could not give more details.

The SQ is investigating.
