History of the Squadron Post-WWII (Aircraft: Harvard, Mustang, Silver Star, Tracker)

No. 420 Squadron reformed at London, Ontario on 15 September 1948, and flew North American Mustang and Harvard aircraft in a fighter role until the squadron disbanded on 1 September 1956. The squadron was re-formed as an Air Reserve squadron based initially at CFB Shearwater, Nova Scotia flying the de Havilland Canada Tracker aircraft that had once been the backbone of the Canadian Naval Air's anti-submarine program. As an Air Reserve Squadron it participated with regular fisheries patrols. It was one of the few active Air Reserve Squadrons in Canada and was paired with the Regular Force's 880 Squadron. The Squadron was rebased to CFB Summerside, Prince Edward Island when their base was downsized. No 420 Squadron was reduced to nil strength on 15 May 1995.
