Lionel Fleury was a Canadian ice hockey administrator who served as president of the Canadian Amateur Hockey Association from 1964 to 1966. Under his leadership, the Canada men's national ice hockey team transitioned from student athletes coached by Father David Bauer into a year-round national team program. Fleury welcomed the Newfoundland Amateur Hockey Association as a new branch member of the national association in 1966, and changed the format of the Memorial Cup playoffs in Eastern Canada from an elimination bracket into a round-robin format to reduce travel costs and address concerns of imbalanced competition. He sought an end to the National Hockey League system of sponsoring amateur teams by replacing it with a draft of players who had graduated from junior ice hockey, and negotiated for a new agreement that was realized after his term as president concluded.
