Alpha Delta Pi's first chapter to be colonized in Canada, Beta Zeta originated with 14 girls as members of local sorority Upsilon Tau. The chapter was installed in 1929 with 25 members, and met in chapter rooms conveniently located on College Street with several members "living in." The chapter moved to a new house in 1935 and again in 1940. They were active in student government, campus organizations and athletics. Jessie Gray, M.D., was the first woman to be elected to the Royal Academy of Surgeons of Canada. Beta Zeta became a casualty during World War II and chapter functions ceased by 1943.
