William Victor Mahony (born September 16, 1949) is a former breaststroke swimmer who represented Canada in multiple international championships from 1966 to 1974, including two Summer Olympics, the Pan American Games, and two Commonwealth Games.[1]
Mahony began his international career at the 1966 Commonwealth Games in Jamaica, with a bronze medal in the 220-yard breaststroke. In Mexico City for the 1968 Summer Olympics, he competed in the semifinals of the 100-metre breaststroke, the preliminary heats of the 200-metre breaststroke, and the finals of the men's 4×100-metre medley relay.[1]
After taking a year off, in his final international event at the 1974 Commonwealth Games in Auckland, New Zealand, he won another gold medal swimming his lifetime fastest Breastroke leg for the Canadian team in the 4×100-metre medley relay, alongside Brian Phillips, Bruce Robertson and Steve Pickell.
From 1977 to 1987 he developed the Adapted Aquatics program at Variety's Treatment Centre in Surrey, British Columbia, and helped to form the British Columbia Branch of the Cerebral Palsy Sports Association. Later, while coaching paraplegic and blind swimmers, he was selected to coach the Canadian swimmers at the 1980 Olympics for the Disabled in the Netherlands. He was awarded Athlete of the Year in New Westminster, and inducted into the BC Swimming Hall of Fame, Canadian Swimming Hall of Fame, and BC Sports Hall of Fame.[1]
