Canadian University Society for Intercollegiate Debate

The Canadian University Society for Intercollegiate Debate (CUSID generally) is the national organization which governs all English language competitive university debating and public speaking in Canada. It sanctions several official annual tournaments and represents Canadian debating domestically and abroad. Its membership consists of student debating unions, sanctioned by their respective universities, from across Canada. CUSID has been described as "a student-run, parliamentary debate league with close ties to the American Parliamentary Debate Association".

Many prominent Canadians were university debaters, including Prime Ministers Justin Trudeau, Joe Clark and Brian Mulroney, MP John Godfrey, Canadian Supreme Court justices Ian Binnie and Morris Fish, songwriter Leonard Cohen, entrepreneur Moses Znaimer, environmentalist David Suzuki, and journalist Ian Hanomansing. CUSID debaters have gone on to notable careers in law, business, government and academia and the presidency of the organization is a highly sought-after position.
