The original school building was Jacobethan Revival and replaced with the Collegiate Gothic wing in 1932.

With the donations from the W. Garfield Weston Foundation and many other corporate sponsors and individuals, the rededication of the 1921 World War I monument back to its original splendour was held.

The Harbordite, founded in 1979, is the club newsletter that keeps former students of the school in contact with one another and up-to-date on Harbord activities.

The Harbord Charitable Foundation was also created at this time, supporting both student scholarships and alumni activities.

The Harbord language program offers courses in Spanish, French, Portuguese and German.
