Initially, the base served as a winter home for units that operated across northern Manitoba. During World War II, the base played an expanded role, participating in the British Commonwealth Air Training Plan (BCATP). During that time, they trained more than 130,000 personnel from across Canada ranging from pilots, navigators, observers and wireless operators. RCAF Station Winnipeg also became an important supply and repair depot and base to ferry and inspect units for the air force.
Following the war, RCAF Station Winnipeg continued to provide training for pilots and navigators from many allied countries, as well as base active RCAF squadrons. The formation of No.2 Air Observer School & Central Navigation School was created from the increased training activities which graduated over 5,000 aircrew from foreign countries.
The February 1, 1968 unification of the RCAF with the Royal Canadian Navy and Canadian Army formed the Canadian Forces. As a result, RCAF Station Winnipeg was renamed as Canadian Forces Base Winnipeg (North).
The Canadian Army camp Fort Osborne Barracks, later renamed Kapyong Barracks, home of the 2nd Battalion, Princess Patricia's Canadian Light Infantry (PPCLI), was merged with the RCAF base, becoming Canadian Forces Base Winnipeg (South). Kapyong Barracks closed in June 2004 and 2PPCLI re-located to CFB Shilo near Brandon. The Kapyong Barracks name was also transferred to the new garrison facility in CFB Shilo.
CFB Winnipeg became home to several transport and utility squadrons, as well as headquarters for Air Command, which was formed in 1975. A realignment of the Canadian Forces in the mid-1990s saw Air Command HQ move to National Defence Headquarters. As with other AIRCOM bases across Canada, CFB Winnipeg's squadrons were grouped under a wing system, in this case 17 Wing Winnipeg, which is the highest-level unit at the base.
The base is home to the Air Force Heritage Museum and Air Park . The Air Park is located on Air Force Way and contains 10 historic aircraft. The museum is located in the 1 Canadian Air Division Headquarters.[5]
