After the reorganization of legal education in Ontario in the mid-1950s, Queen's Faculty of Law opened in 1957 in the new John A. Macdonald Hall. Other construction projects at Queen's in the 1950s included the construction of Richardson Hall to house Queen's administrative offices and Dunning Hall. By the end of the 1960s, like many other Canadian universities, Queen's tripled its enrolment and greatly expanded its faculty, staff, and facilities, as a result of the baby boom and generous support from the public sector. By the mid-1970s, the university had 10,000 full-time students. Among the new facilities were three more residences and separate buildings for the Departments of Mathematics, Physics, Biology and Psychology, Social Sciences and the Humanities.
