The University of Toronto has traditionally been a decentralized institution, with governing authority shared among its central administration, academic faculties and colleges.  The Governing Council is the unicameral legislative organ of the central administration, overseeing general academic, business and institutional affairs.  Before 1971, the university was governed under a bicameral system composed of the board of governors and the university senate.  The chancellor, usually a former governor general , lieutenant governor , premier or diplomat, is the ceremonial head of the university. The president is appointed by the council as the chief executive.
