Our school opened in September 1959, and was regarded as the most modern and advanced of its time.
The post-war baby boom contributed to the need for expanded school capacity across Scarborough. Two round of expansion followed within 12 years, adding two new wings of classrooms, an additional gymnasium, expanded library, plus expanded administrative offices.
At its peak around 1978, the school welcomed over 2,300 students and 130 teaching faculty.
Due to declining enrollment, in 2014 the Toronto District School Board started plans to consolidate the neighbouring Bendale Technical School (located on Midland Avenue north of Lawrence Avenue) and Thomson Collegiate into a single new school building.
The new school was opened in December 2019. The original school building was demolished in September 2020. A new housing development will take its place.
