Ottawa Fire Investigators say the fire which destroyed a portable classroom at a Stittsville high school is arson.
The overnight fire happened at Sacred Heart Catholic High School on Abbott Street just before 2 a.m. Wednesday.
When they arrived, they found the portable fully engulfed in flames. Firefighters had the blaze under control in 15 minutes and were able to protect the nearby buildings.
The fire caused $100,000 in damage.
Ottawa Fire and Ottawa Police Arson investigators are still probing two fires at houses under construction in Stittsville earlier this month.
In this incident, police say they are looking for two males.
