While Brampton Centennial Secondary School welcomed students in the fall of 1967, the Canadian Centennial year, its official opening was held some months later in February 1968.

The opening ceremonies included a performance by the BCSS Orchestra, and an address by Ontario Minister of Education Bill Davis.

Peel’s population was comparatively low at the time, and only Brampton, Streetsville and Port Credit had high schools. A Bolton high school had closed decades earlier.

As such, Brampton’s shared board was known as the Central Peel District High School Board, and served students from much of Peel’s middle.
