The Cold Lake Air Force Museum is a military aviation museum located in Cold Lake, Alberta. The museum preserves and exhibits the heritage and history of 4 Wing Cold Lake and 42 Radar Squadron. The Air Force Museum is actually one of four museums based on the old site of 42 Radar Squadron, who re-located to CFB Cold Lake in 1992. The Oil and Gas, Heritage and Aboriginal Museums are connected to the Air Force Museum through a covered hallway affectionately dubbed 'The Tunnel'. All together, the museums are referred to as the Cold Lake Museums or the Tri-City Museums. The old facility of 42 Radar Squadron was decommissioned in 1992 and the museum opened its doors for the first time on July 1, 1998.
