Forward William “Bill” Colvin spent nearly his entire life, and hockey career, in the province of Ontario. A Toronto native, he began with the city’s junior St. Michaels Buzzers in 1951, before switching to the junior St. Michaels Majors for three seasons. At this point, in 1955, he was recruited by the Kitchener-Waterloo Dutchmen of the Ontario Hockey Association, his first senior level team, and joined them as they represented Canada at the 1956 Winter Olympics. At the tournament he played in four matches, but did not score any goals. After taking home an international bronze medal he continued his international sojourn by signing with the Toledo Mercurys of the International Hockey League for the 1956-1957 season. He spent his final two full seasons in the Eastern Ontario Senior Hockey League with two Kingston teams, the CKLC’s and the Merchants, prior to undertaking a one year hiatus from the sport. He returned in 1960 for three games with the Eastern Professional Hockey League’s Kingston Frontenacs and was signed with the Rouyn-Noranda Alouettes of the Northern Ontario Hockey Association in 1961, although it is unclear if he played in any matches with them. A graduate of Queen’s University, he had a career as a lawyer and continued to play hockey at the master’s level for the Huntsville, Ontario Oldtimers beyond his official retirement, in addition to helping raise funds for the team’s associated charities.
