Juckes joined the
Canadian Amateur Hockey Association (CAHA) executive in 1955, serving as second vice-president until 1957. In this role, he was also the chairman of
minor ice hockey in Canada, and organized the first "Young Canada Hockey Week" held from February 4 to 11, 1957. The event was supported by the CAHA and its affiliate branches, and served to promote participation in minor ice hockey with expanded newspaper, radio, television coverage. The event gained recognition for Juckes' efforts in a letter from prime minister
Louis St. Laurent. Juckes served as president of the CAHA for one year from 1959 to 1960, succeeding
Robert Lebel. Juckes was named secretary-manager of CAHA on May 24, 1960, after the death of
George Dudley, becoming the first western Canadian to hold the post. Changes were proposed to the constitution at the same time to give broader powers to the secretary-manager position, which was already considered the most powerful position within the CAHA.
Jack Roxburgh was named the new president of the CAHA on May 27 to fill the vacant position. Juckes worked mostly by himself doing CAHA administration, with only a part-time secretary assisting with correspondence. The dual roles of registrar-treasurer, and secretary-manager were formally combined into the title of executive director in 1968, which he held until 1977. He was the CAHA delegate to the
International Ice Hockey Federation from 1960 to 1977, and was an IIHF director from 1966 to 1972. Juckes authored a report for the CAHA after Canada's
1960 Winter Olympics results, arguing for more coherence and continuity in its international representatives, as opposed to sending amateur club teams. In 1962,
Father David Bauer made his proposal to start a
Canadian national team in a meeting with Juckes and CAHA president Art Potter. He helped set up the national team with Father Bauer in 1962, then established the first CAHA office in Winnipeg in 1964. Juckes later facilitated the joint effort between Bauer's national team with the
Winnipeg Maroons to perpetuate the national team program by bringing in more coaches and players, effectively merging the two teams. He also supported creating a second national squad prior to the
1968 Winter Olympics, to have more players with the same type of training and experiences to increase the talent pool, also to reduce the workload of extensive exhibitions tours through Europe. Juckes was chosen to be part of the Canadian delegation to the meetings in 1969, which aimed to negotiate the use of professionals in IIHF competitions, before Canada ultimately withdrew from international competition in 1970. Later the same year, he and the CAHA offices relocated to
Ottawa. Juckes is also credited with the efforts that established the
World Junior Championship. He used his position as an IIHF director to negotiate an upper age limit of 20 for the juniors, which had been a main point of contention with European delegates, and prevented any previous agreement for sanctioned events. The first official tournament was the
1977 World Junior Ice Hockey Championships. During his tenure with the CAHA, Juckes supported having rules to limit body contact in minor hockey, and he was responsible to implement helmet safety rules. In an interview he gave in May 1979, Juckes said that Canada's withdrawal from international competition in 1970 was the toughest decision he had been involved with, and was something he opposed. He felt it more effective to host the
1970 World Ice Hockey Championships under protest, then withdraw if necessary. Juckes also mentioned that the withdrawal of the
Western Canadian Hockey League teams from the CAHA was one of his biggest regrets. ==Hockey honours and awards==
