Harbord Collegiate Institute and Jarvis C.I., both by school-board architect C. E. Cyril Dyson in the 1920s and 1930s, have figures so similar in style that they must have been designed by the same person.
Flanking the main entrance to each building is an academic figure (the Jarvis scholar above – an apparent math phobe, and the Harbord scholar below),
The latter would suggest that the figures illustrate the mens sana in corpore sano philosophy— healthy mind, healthy body. (However, similar figures appear inside Northern Secondary School, where it is more apparent that the spheres are globes and not sport balls.)
Outside the third-storey art-studio window at Jarvis are more student figures, including a reader and a writer.
