Founded in 1930, it was originally known as Northern Vocational School, until the twenty-fifth anniversary when the name was changed to Northern Technical-Commercial, which lasted for three years until the present name, Northern Secondary School, came into use because a definite district had been assigned for matriculation students. Northern was the first Ontario school to have a student council. The school is a pilot site of a Toronto Police Service program that places on-duty police officers in schools. On May 13, 2016 it was alleged that a bomb was planted on the premises and the school was shut down to investigate. No explosive devices were found.
Architecture
Northern Secondary is built in the Collegiate Gothic style, has a floor space of about 121,317 square feet and contains one hundred and fifteen rooms. C.E.C. Dyson was the school's original architect. Although little is known about him, he was the school board's architect from 1921 until 1949. Northern is known for the grotesques which exist on the exterior, throughout the entrance foyer and inside the auditorium. Further evidence of the Gothic Collegiate style can be found in the vaulted ceilings of the hallways, and the arched doorways and windows featured throughout the building. As stated on a plaque inside the main entrance, during the 60s a major addition was built which significantly altered the rear of the school. These renovations changed little about the original parts of the building. Although once grand, over the decades, the facility has fallen into considerable disrepair and is in need of extensive renovation.
