The Bishop Strachan School had a variety of temporary homes since the founding: First opened in September 1867 at Pinehurst, formerly Mrs Forster's Girls School (1853-1866) on west side of McCaul Street between Dundas Street and Grange Road near the Art Gallery of Toronto (currently the Art Gallery of Ontario).

[7] In September 1915, The Bishop Strachan School opened as a large gothic-style structure, made of Credit Valley limestone, at its present-day Forest Hill location at 298 Lonsdale Road.

[8] This new addition included new classrooms, a fitness centre, a full gymnasium and underground parking.

The new wing creates a functional courtyard for playgrounds while reducing the mass of the building along the residential streetscape.

To preserve the highly valued outdoor playing field and tennis courts, the fitness centre, gymnasium and parking are located below ground and connected to the main building via a skylit corridor link.
