Design and development
Canadair began work on the CL-28 in April 1954 and at the time it was the largest aircraft built in Canada. The hybrid design, initially referred to as the 'Britannia Maritime Reconnaissance', or 'Britannia MR', was derived from the Bristol Britannia transport, having the same wings, tail surfaces and landing gear except for being "Americanized" – meaning that it used the same general design, but changed the British materials and standard parts for North American ones.
The fuselage was completely redesigned by Canadair, going from the pressure cabin of the Britannia to an unpressurised one with bomb bays fore and aft of the wings. The powerplant was also changed from the Bristol Proteus turboprop engines to Wright R-3350 compound (piston) engines, which had lower fuel consumption necessary for extended missions at low level. At the design stage the other possible engine was the Napier Nomad, another turbo compound engine, although the Nomad was later cancelled.

The Argus replaced the RCAF Lancaster and Lockheed P-2 Neptune aircraft types previously flown in the maritime roles. One of the most effective anti-submarine warfare (ASW) aircraft of its day, the Argus was a mainstay for the RCAF. A large amount of equipment was carried, including: search radar, sonobuoys, electronic counter measures (ECM), explosive echo ranging (EER) and magnetic anomaly detector (MAD). Up to 8,000 lb (3,632 kg) of weapons could be carried in the bomb bays, including torpedoes, bombs, mines and depth charges.
