After the war, Swansea was twice recommissioned between April 1948 and November 1953 for training cadets.
In August–September 1949, Swansea sailed north to Baffin Island, making several port visits including Godthaab, capital city of Greenland.
This was the farthest north a Royal Canadian Naval ship had travelled.
On 15 September, while sailing south along the coast of Labrador, Swansea was ordered to the aid of the stricken supply vessel Malahat near Mansel Island in Hudson Bay.
Arriving on 18 September, Swansea took Malahat under tow and brought the supply vessel to Goose Bay, Newfoundland, nearly 1,200 nautical miles (2,200 km; 1,400 mi).
Swansea left the damaged ship there and proceeded to Halifax.
In May 1951, Crescent, La Hulloise and Swansea sailed to the United Kingdom on a training cruise.
In January 1952, the frigate made a three-week training cruise to the Caribbean Sea, visiting Nassau, Bahamas, and Groton, Connecticut.
In May 1952, with Crescent and La Hulloise, the frigate made a training cruise to Gibraltar and the French Riviera.
On 15 June 1953 she attended the Coronation of Queen Elizabeth II Fleet Review at Spithead.

From 1956 to 1957, Swansea underwent conversion to a Prestonian-class ocean escort.
This meant a flush-decked appearance, with a larger bridge and taller funnel.
Her hull forward was strengthened against ice and the quarterdeck was enclosed to contain two Squid anti-submarine mortars.
Swansea was recommissioned 14 November 1957 with pennant number 306.
She served primarily on the east coast.
In 1961, the frigate was a member of the Ninth Canadian Escort Squadron.
She was paid off 14 October 1966 and was sold for scrap and broken up at Savona, Italy, in 1967.
