Cayuga served a total of three tours of Korea, the last in 1954 after the conflict had ended. Cayuga was part of this initial first dispatch of three ships by Canada to Korea, departing Esquimalt on 5 July 1950. In 1952, Cayuga was reconstructed as a destroyer escort and given the new hull number 218. It was on this vessel that Ferdinand Demara, "the great impostor", served while impersonating a Canadian medical officer.
