It sits in gothic splendour on top of the escarpment overlooking downtown TORONTO. A heritage building – former home of Senator John MacDonald, this house (with its tower observatory) is now occupied by the Brothers of the Christian Schools. De La Salle Oaklands, so-named for the Brothers and the great oak trees dotting the campus, is a co-educational Catholic school founded in 1851, and located here in the 1930’s.

Toronto Savvy 
My father attended Del La Salle Oaklands in the mid forties on a scholarship.
I understand that it is a co-Ed Catholic school and offers enrolment in the primary grades as well as secondary grades. I cannot speak to the quality of the education today.
I wonder how much of the original interiors survive? Grand salons and classrooms are basically different.
Now any changes would have to meet the standards of Ontario Heritage Trust. Not a requirement of days gone by. Perhaps they are using it for faculty offices and meeting rooms.
