William "Billy" MacMillan has achieved a level of sport success that few other Islanders have. He was a player on several provincial, regional, and national championship hockey teams, and is the owner of the coveted Olympic scroll and Stanley Cup ring. After being recruited to play at St. Michael's College and enjoying a highly successful junior "A" career, MacMillan returned to Charlottetown to pursue his academic studies, leading the Saint Dunstan's Saints to the conference title and winning the scoring crown and the MVP award. After participating in four World Hockey Championships and winning bronze at the 1968 Olympic Winter Games, he was signed to the Toronto Maple Leafs, scoring 22 goals in his rookie season. He later was on the coaching staff of several NHL teams and then returned home to coach the UPEI Panthers, guiding UPEI to its last conference title in 1990-91.
