No. 431 Squadron formed on 11 November 1942, at RAF Burn (in North Yorkshire), flying Wellington B.X medium bombers with No. 4 Group RAF Bomber Command. The squadron moved to RAF Tholthorpe in mid-1943 as part of the move to bring all RCAF squadrons into one operational group – No. 6 Group RCAF – and converted to Halifax B.V four-engined heavy bombers. In December 1943 the squadron moved to RAF Croft where it was re-equipped with Halifax III's and later, Lancaster B.X aircraft. 
The squadron moved to RCAF Station Dartmouth, Nova Scotia after the war, disbanding there on 5 September 1945.No. 431 (Fighter) Squadron re-formed at RCAF Station Bagotville on 18 January 1954, using the new Canadair F-86 Sabre. The squadron was formed on a temporary basis until there were enough new CF-100s available to fulfill RCAF squadron needs. No. 431's duties included aerial combat training and displaying the capabilities of jet operations to the public at air shows, the largest being "Operation Prairie Pacific": a 50-minute exhibition that travelled to selected locations across western Canada. The team consisted of four Sabres and a solo aircraft. This was the first Sabre team to be authorized to perform formation aerobatics in Canada. The unit was disbanded on 1 October 1954.
