Barrie Police along with Barrie Fire were called to St Peters High School for a report of a fire on the second floor.
Barrie Fire immediately extinguished a small fire that appears to have been set in a boy’s washroom.
There were no injuries to any students or Staff members, but the school was closed due to the amount of smoke the fire had produced.
Any witnesses to the incident are asked to contact PC Hopper of the Barrie Police Service
