On 1 April 1949, No. 11 Group, which had been formed with headquarters at Winnipeg on 1 March 1947, was designated Tactical Group in keeping with the R.C.A.F.'s transition in organization from a geographical to a functional basis. Two years later, on 1 August 1951, Tactical Group became autonomous, under the direct control of Air Force Headquarters, and was moved to Edmonton where it was merged with North-West Air Command as Tactical Air Group. It was elevated to Command status as No. 1 Tactical Air Command on 1 June 1953. The prefix "1" was later dropped.
