Multiple cars were set on fire in the parking lot between two apartment buildings on Villeneuve Street at around 4:30 a.m.
At least four vehicles were targeted in an early-morning arson Monday in the borough of Montreal North.
Firefighters quickly put out the blaze but the vehicles are a total loss. Smoke billowed into the adjacent building forcing a complete evacuation.
Montreal police spokesperson Raphaël Bergeron said traces of accelerants were found on the vehicles, triggering an arson squad investigation.
No suspect has been identified by police. The vehicle owners will be questioned, but police said none of them were threatened prior to the fire.
There were no injuries.
