Lakeridge Health Ajax and Pickering

The Ajax Division was the University of Toronto's campus in Ajax, an unincorporated community (now a town) within the Pickering Township of Ontario, Canada. It was located at the site of the defunct Defence Industries Limited Pickering Works munitions plant, which was leased by the federal government to the university for a nominal rent. The Ajax Division was set up to meet the increasing demand for engineering education from World War II veterans returning from the war theatre in Europe. The university's downtown Toronto campus accommodated 400 veterans who had completed at least 29 months of active service; the Ajax campus accommodated the rest of the engineering students, both veterans and non-veterans. The campus was active between January 1946 and April 1949, with approximately 6,000 students attending classes there. At its peak, during 1946–47, it had 3,312 students and 210 instructors. By 1949, the university had built new engineering facilities in downtown Toronto, and decided to move the classes back to Toronto, declining the government's offer to buy the Ajax site for cheap.
