In the early 1960s, the City of Windsor's growth and demands for higher education led to further restructuring. A petition was made to the Province of Ontario for the creation of a non-denominational University of Windsor by the board of governors and regents of Assumption University and the board of directors of Essex College. The University of Windsor came into existence through its incorporation under an Act of the Legislative Assembly of Ontario on December 19, 1962. The transition from an historic Roman Catholic university to a non-denominational provincial university was an unprecedented development.
