The Unit Ops Lab has been the central teaching facility for Chemical Engineering at the University of Toronto since 1949, with a tradition of providing students with training in technologies and processes that are directly relevant to the wide range of chemical engineering industries.
The photos below give a glimpse of the lab through the decades.

Canada’s first subcritical teaching reactor
In 1958, the Unit Ops Lab became the home of Canada’s first subcritical nuclear reactor for teaching purposes. This addition to chemical engineering training addressed the increasing need for nuclear engineers in this rapidly-growing sector.
