The legal existence of Concordia dates from August 24, 1974. The integration of the various faculties of the two institutions into a coherent whole took several years. The five faculties of the new university were a combination of existing faculties and departments prior to the merger. There was a Faculty of Commerce, Faculty of Science and Faculty of Arts at Sir George Williams University. Additionally, there was a Faculty of Arts and Science at Loyola College. The Faculty of Engineering of both institutions had previously been combined.
