She was allocated in February to EG C-9, and made the crossing to the group’s Londonderry base as an escort to SC.168. She spent the rest of the war as a mid-ocean escort, returning to Canada in Jun 1945, to be employed as a troop carrier between St. John’s, Newfoundland, and Quebec City. One of the few frigates not taken in hand for tropicalization, she was paid off on 10 Nov 1945 and laid up at Shelburne, NS. She was sold in Dec 1945 to Marine Industries Ltd., but later re-acquired and converted to a Prestonian class ocean escort (316), and re-commissioned on 1 Jun 1954 .
