In January 1945, "Inch Arran" worked up at Bermuda and was assigned to escort group 28 upon her return in February. The ship spent the remainder of the Second World War on patrol and escort duties in Halifax. The most notable escort duty was alongside on 13 May 1945 approximately south-southeast of Sable Island, Nova Scotia. Here both vessels escorted the surrendered back to harbor. Before any of the three vessels were granted entry through the anti-submarine gates of Shelburne Harbor, "U-889" was boarded and thoroughly inspected. On 6 June 1945, "Inch Arran" began a tropicalization refit in preparation for service in the Pacific Ocean. This was suspended on 20 August due to the Surrender of Japan, and she was paid off on 28 November 1945.
