G. Sydney Halter’s career in sport management included involvement at the provincial and national levels. In 1924, Halter first became involved in sports administration as the manager of the University of Manitoba hockey team. Halter was the president of the Winnipeg Amateur Athletic Association Track & Field Club and later took the positions of secretary and president of the Manitoba Athletic Union which introduced him to executive duties with the Amateur Athletic Union of Canada. In 1938, Halter became President of the A.A.U.C. and held that position until 1946. Locally, Halter assumed the post of First Treasurer with the Winnipeg Football Club in 1935 and his service on the Blue Bombers executive culminated in his becoming President in 1942.

During WWII, Halter joined the R.C.A.F. and following his discharge from the military he became involved in football once again. In 1952, Halter was appointed Deputy Commissioner of the Western Interprovincial Football Union (W.I.F.U.) and was named President the following year. Halter was also a member of the Canada Football Council and Registrar for both the Eastern and Western Football Conferences. In 1958, the W.I.F.U. and the Eastern Football Conference amalgamated into the Canadian Football League and Halter was appointed as its first Commissioner. During his five year tenure, the foundation for the operation of today’s C.F.L. was developed.

In 1966, the C.F.L. established the G.S. Halter Trust Fund to benefit the Canadian Olympic Association.

In 1968, Halter was elected to the Board of Trustees of the Canadian Schenley Football Awards. Syd Halter was named to the Order of Canada and was inducted into Canada’s Sports Hall of Fame and the C.F.L. Hall of Fame.
