Laid down as HMS Woolvesey Castle, she was transferred to the RCN and commissioned on June 6, 1944, on the Clyde. She worked up at Stornoway early in July and joined EG C-5 at Londonderry later that month, leaving on August 11 for ONS.248, her first convoy. In November Huntsville missed a convoy while under repair in Halifax and acted as local escort to one convoy from St. John's to New York - seemingly the only ship of her class to visit there. Rejoining the Atlantic convoy cycle in December, she left Londonderry for the last time on April 16, 1945, to meet ON.297. In May she commenced refit at Halifax, completed in August, and in September was placed in reserve. She was paid off for disposal on February 15, 1946, and sold that year, entering service in 1947 as SS Wellington Kent. Renamed Belle Isle II in 1951, she was sunk in a collision off Trois-Rivieres on August 19, 1940.
