Hazmat crews rushed to a Toronto high school on Friday after a reported chemical leak forced the building's evacuation.
Police said they received the emergency call at Downsview Secondary School, on Hawksdale Road, near Keele Street and Wilson Avenue, shortly before 10 a.m.
Thirteen fire trucks and other support vehicles were seen outside the school late Friday morning as the building was evacuated.
Toronto police confirmed at about noon that the leak had been fixed and that there was no danger to the public. Students and teachers returned to class shortly after.
TDSB spokesman Ryan Bird said it appears that a chemical valve broke in the school's pool area, causing the leak.
Toronto Fire officials said they received a report of a large gas leak under the school. When they arrived they found a chlorine tank had cracked loose while located near a tank of acid.
Fire officials said they found no fumes and no one was injured, but there had been concerns that the two chemicals would mix together.
