The Mk. IIIs were only three years old when supplanted by the Mk. IV in RCAF service, and the
Chilean Air Force happily purchased 30 ex-RCAF Mk. IIIs in 1955, ushering them into the jet age. The Canucks remained in service in Chile until 1969.

Another Latin American country to buy second-hand Mk. IIIs was the
Dominican Air Force who took 22, also in 1955. This was the island nation's first fighter jet, and the FAD operated them until 1972.

The
Indian Air Force purchased 50 new Canuck Mk. IIIs from Avro, along with a licence to manufacture them; they were designated "Kirpan" in IAF service. The 50 Canadian-built aircraft were operated by the IAF until 1964, and were replaced by a HAL-designed derivative.

Canada supplied the Kuomintang government on Taiwan with 58 new Canuck Mk. IIIs in 1953, which the
Republic of China Air Force operated as front-line interceptors until 1956, when they began to be replaced by Mk. Vs; the Mk. IIIs remained in service with reserve squadrons until 1972.

The
Royal Air Force purchased a small number of new Mk. IIIs from Avro Canada. The only front-line squadron to operate them was 5 Sqn, and they remained in service only 4 years before being withdrawn and returned to Canada. Several of the ex-RAF Clunks found new life with the RCAF as CEF-100s.
