On 1 November 1952 No 414 Fighter Squadron reformed at RCAF Station Bagotville. The following summer on 24 August 1953 as part of "Leap Frog IV" the squadron moved to 4 Wing Baden-Soellingen flying the Canadair Mark.4 Sabre. Four years later on 14 July 1957 the squadron disbanded to make room for the arrival of 419 Squadron flying the Avro Canada CF-100.

On 5 August 1957, the squadron reformed at RCAF Station North Bay where it operated as an all-weather fighter squadron flying the CF-100 Canuck and the McDonnell CF-101 Voodoo until 30 June 1964 when it was disbanded once more.

The squadron then reformed on 15 September 1967 at RCAF Station St Hubert in its new role as an electronic warfare squadron flying the CF-100. In August 1972 the squadron moved to CFB North Bay where it remained for the next twenty years flying the CF-100, Dassault CC-117 Falcon and McDonnell EF-101B "Electric Voodoo". In 1992 the squadron was split into two parts with one part going to CFB Comox as No 414 Composite Squadron and the other part going to CFB Greenwood as 434 Composite Squadron. In 1993 the squadron changed its name to No 414 Combat Support Squadron when it was equipped with the Canadair CT-133 Silver Star. The squadron was disbanded in 2002 when its duties were contracted out to a civilian company.

On 7 December 2007 approval was received for the squadron to stand up once more, this time as 414 EWS (Electronic Warfare Support) Squadron. Belonging to the RCAF Aerospace Warfare Centre, the squadron is based in Ottawa and is composed of military Electronic Warfare Officers who fulfill the combat support role, flying on civilian contracted aircraft.^[2]
