In the summer of 1977, Rick Hansen, working with the Canadian Wheelchair Sports Association, invited Fox to try out for his wheelchair basketball team. Although he was undergoing chemotherapy treatments at the time, Fox's energy impressed Hansen. Less than two months after learning how to play the sport, Fox was named a member of the team for the national championship in Edmonton. He won three national titles with the team, and was named an all-star by the North American Wheelchair Basketball Association in 1980.
