When I drive to Blue Mountains, Ontario to go snowboarding, I pass through the town of Stayner, where I have always admired the architecture of the high school as being really good midcentury modern architecture. Just past Blue Mountain, in the town of Thornbury, there is a lovely building named the Leonard .E Shore Memorial Library. It's named after the co-founder of Shore and Moffat, doing seriously high quality modernist schools and office buildings through the 50s and 60s. The firm evolved into Shore Tilbe Irwin + Partners and has now been absorbed into the green giant of architecture firms, Perkins + Will.
Fifty years later is still doing seriously high quality modernist schools, as demonstrated by the new Instructional Centre at the University of Toronto's Mississauga campus.
