Commissioned at Kingston on October 19, 1944, she visited the Ontario port for which she was named before leaving for Halifax, where she arrived early in November. Belleville continued fitting out at Halifax until Mid-January, then sailed to Bermuda for a month's working-up. Further repairs followed on her return, after which she was allocated to EG C-5, leaving St. John's on March 28 to join her first convoy, HX.346. She made three Atlantic crossing before the war's end, leaving Londonderry for the last time at the beginning of June, 1945. She was paid off on July 5, 1945, and placed in reserve at Sorel until 1947, when she was sold to the Dominican Republic and re-named Juan Bautista Combiaso. She was broken up in 1972.
