The City Adult Learning Centre (CALC) is a secondary school that offers an academic program for adult students, ages 21 and over,  who wish to earn the Ontario Secondary School Diploma (OSSD).

It was originally Parkway Vocational School, which was built in 1963 and the chief architect was F. C. Etherington.

Construction of the new school was undertaken as part of the general program to improve technical and vocational schools in Toronto. Location is on a six and a half acre site overlooking the Don Valley. To conserve land on the restricted site the main centre containing the library, administrative offices, and thirty- one classrooms is a six storey block linked, by covered walkways, to units on the north and south. The classroom block is served by three high speed elevators and one freight elevator. A pedestrian bridge provides access to a city park and recreational and athletic facilities which are used by students during school hours.
