The North Cowichan/Duncan RCMP and specialized fire investigators are now looking into the incident. It's the second time this week that a suspicious fire closed a school in Duncan. On Monday, all classes at Drinkwater Elementary were cancelled for the day after a fire filled the building’s halls and classrooms with smoke.
