Commissioned at Montreal on June 26, 1941, Prescott arrived at Halifax on July 4 and was attached briefly to Halifax Force before arriving at St. John's on August 31 to join Newfoundland Command. She spent the rest of the year escorting convoys between St. John's and Iceland, but early in 1942 experienced mechanical difficulties requiring two months' repairs at Liverpool, N.S. Resuming her mid-ocean duties on April 21, she made two round trips to Londonderry before being transferred to WLEF in July. IN September she was assigned to duties in connection with Operation "Torch", returning to Canada on April 4, 1943. Late that month she began a six-month refit at Liverpool, N.S., including extension of her fo'c's'le. After work-ups at Pictou she sailed from St. John's on December 19 for the U.K. to join EG 6, Londonderry. She served with the group, principally as escort to U.K.- Gibraltar/Freetown convoys, until April, 1944, when its corvettes were replaced with frigates, then joined Western Approaches Command, Greenock, for invasion duties. In September she returned to Liverpool, N.S., for another refit and, after working up, went back to the U.K. to serve with Nore Command until the end of the war. Returning to Halifax late in May, 1945, she was paid off at Sorel July 20 and broken up in 1951 at Hamilton.
