In Ottawa, officials at the Ecole Maimonides boosted their original $40,000 damage estimate up to $75,000 after seeing the extent of smoke damage throughout the school.
Ottawa police said the fire was started by someone who broke into the building through a window and set some papers ablaze, which then ignited a nearby couch. No arrests have yet been made.
Ecole Maimonides, which has about 100 students from preschool to the eighth grade, was the target of an arson attack three years ago that left it closed for a month.
