After arriving in St. John’s, Newfoundland in 1969, and finding no club to play for, Luke established the St. John’s club and was co-founder of the Newfoundland Rugby Union and its first president.
Luke played 16 test matches for Canada, making his debut in 1974 against Tonga and bowing out against the USA in 1982. Luke captained Canada on eight occasions. He also represented the Barbarians on three occasions and was a member of the Overseas XV that played against Wales as part of the Welsh Rugby Union Centenary celebrations. He also played for the Meralomas in Canada and for the Pirates R.F.C. and Harlequins F.C. in the UK.
He was the coach and manager of Canada’s sevens team in the 1981 Hong Kong Sevens and also coached Canada’s U21 team from 1987-1989. He was an assistant coach and manager of the Canadian squad that reached the quarterfinals of the 1991 Rugby World Cup.
Luke served on the Board of Rugby Canada and was a member and then Chair of the Rugby Canada National Coaching Committee for over 20 years. He became a Master Coach in Canada's National Coaching Certification Program before being elected Chair of the National Coaching Certification Council in 1993.
In 1999, Luke was the recipient of the 3M Coaching Association of Canada Coaching Award for Sport Development and in 2006 received the IRB Development Award for his contributions to the growth of rugby in Canada.
