Three-time Olympian Harry Geris was found dead on Thursday in London, Ont. He was 60.
A construction worker found his body on Thursday behind a high school where Geris was delivering wrestling mats for a tournament.
Police said foul play is not suspected but an autopsy will be performed to determine the cause of death.
Known as the gentle giant of Canadian wrestling, Geris competed as a heavyweight wrestler for Canada at the Olympics in Mexico City in 1968, Munich in 1972 and Montreal in 1976.
He was a 10-time national champion.
Glynn Leyshon, a former University of Western Ontario wrestling coach who took Geris to his first international match in 1964, said Geris will be "sorely missed."
He said Geris "did an awful lot for the sport and, as a friend, he'd do anything for you."
