Commissioned at Collingwood, Ont., on October 6, 1944, West York arrived at Halifax in mid-November and left a month later for Bermuda to work up. In February, 1945, she joined EG C-5 at St. John's, leaving February 16 to rendezvous with her maiden convoy, HX.338. She made three round trips across the Atlantic before the end of her career, the last one as escort to ON.305, which she joined from Londonderry at the end of May, 1945. Paid off on July 9, and laid up at Sorel, she was sold later that yearr for commercial use. As SS West York, she was towing the decommissioned HMCS Assiniboine when the towline parted and the destroyer was wrecked on Prince Edward Island, November 7, 1945. The former West York sailed under a variety of names and flags, returning to Canadian registry in 1960 as Federal Express. She sank at Montreal on May 5, 1960, after being in collision, and her after section was raised and broken up later that year.
