The program became quite popular to the point where it moved to Hopewell Avenue Public School and later Ottawa Technical High School in order to accommodate the growing number of students.

The new program continued to grow and, in 1929, the program was moved to a newly-built section of Glebe Collegiate Institute where the High School of Commerce was established as Ottawa's fourth public high school.

In 1967, the High School of Commerce moved to its own building on Rochester Street.

This was considered an extremely modern facility and was notable for having an IBM 1401 computer on the third floor.

This program gradually grew and, in 1990, the High School of Commerce was closed.
