He later assisted in founding the Northwestern Ontario Curling Association, became its inaugural president in 1947, and sought for recognition as its own branch within the DCA to compete for The Brier national championship.

[2][9] Sargent led a group of five investors in 1928, who sought a junior hockey team based in Port Arthur to compete for the Memorial Cup.

The Thunder Bay Amateur Hockey Association (TBAHA) feared that the plan to group the best players on one team would weaken the local junior league and did not approve the endeavour.

[15] He also served on the CAHA committee to negotiate professional-amateur agreements with the National Hockey League (NHL) from 1938 to 1955, along with W. G. Hardy and George Dudley.

[16] Sargent accompanied the Port Arthur Bearcats to the 1939 Allan Cup championship, which they won versus the Montreal Royals in four games.

[28] The CAHA reached a new agreement with the NHL in November 1940, which included payments to junior or senior clubs for developing players signed by professional teams.

The new agreement also stipulated that players and teams would be suspended for improper transfers, and gave Sargent an $800 honorarium to cover expenses as an executive.

[32] He stated that the CAHA would take measures to ensure faster and cleaner hockey, and that proposals would be forthcoming at the upcoming meeting with the NHL to eliminate high-sticking, boarding and body checking injuries.

[34] The CAHA adopted new rules in 1941, to assist in finding replacement players during wartime conditions;[35] and sought for temporary reinstatement of professionals as amateurs, who were unable to travel to the United States during the war.

[43] In August 1942, the CAHA was requested to submit a brief to military service selection officials with the Government of Canada, to summarize the current participation numbers and its future plans.

[50] He stated that his first term as president had been the most financially successful for the CAHA to date, with a profit near $60,000 and the ability to put $10,500 towards minor hockey grants.

The CAHA also approved a recommendation for a centre ice red line which would allow forward passes to open up the play, instead of the existing offside rule.

[56][57] Sargent advised CAHA teams that a junior-aged player who enlisted would be required to return to his previous club after completing military service.

[58] Canadian Army teams later withdrew from CAHA national playoffs, but were permitted to play in local and intramural sports leagues with other garrisons.

[60] Sargent attended a meeting between the CAHA and the NHL in September 1943, and accepted a proposal from a group in Kingston, Ontario, to establish a Hockey Hall of Fame.

[64] The CAHA gave approval for a new international senior hockey league to include teams in British Columbia, Washington and Oregon.

[69] The Pacific Coast Hockey League began operating in the 1944–45 season, and Sargent received complaints about junior-aged players being offered contracts.

He sought to follow proper international transfers to limit the number of junior-aged players leaving Canada; and for an AHAUS decision on its affiliation, professional status and whether the existing professional-amateur agreement applied.

[70] The CAHA was also faced with limited growth prospects of junior hockey in Western Canada due to the number of rinks available and not enough ice time.

[72] He cautioned that the western branches of the CAHA would be fighting to have the clause removed from the constitution which allowed exemptions for preparatory school transfers.

[74] While there was ample support for senior hockey in Vancouver, he was concerned about the reluctance teams from Quebec to travel west for the Allan Cup during wartime conditions.

The Montreal Royals and Valleyfield Braves who appeared to be the strongest teams in Eastern Canada, and both declined to travel across the country due to their players' need to make a living rather than play hockey.

[89] Sargent supported the practice of allowing less-populated districts in the CAHA to add players from other teams for the playoffs, to make them more competitive.

After the Port Arthur Bruins from the TBAHA won the 1948 Memorial Cup, the more-populated Ontario and Manitoba associations wanted to reverse the practice.

[92] Sargent represented the CAHA at 1951 general meeting of the IIHF in Paris, and accompanied the Lethbridge Maple Leafs on their European tour and victory at the 1951 Ice Hockey World Championships.

He expressed a growing dislike for the physical style of hockey being played, and had hoped to reintroduce rules for less contact and to prevent injuries.

[3][4] Sargent played second on the rink skipped by Grant Watson which won the 1953 Northern Ontario Men's Provincial Curling Championship.

[108] Sargent was elected third vice-president of the DCA in March 1962, which enacted residency rules for its curlers in the Brier to prevent teams switching associations in its playoffs.

Proposals limited the top bonspiel prize to $800 per rink or $200 per curler, which would have allowed only the independently wealthy to take time off and travel to the national events.

[121][122] In March 1973, Sargent sat on the nomination committee to select the first group of inductees into the Canadian Curling Hall of Fame to be established in Winnipeg.
