Commissioned at Sorel on June 5, 1941, Sorel arrived at Halifax on June 12. She joined Halifax Force later that month but transferred in September to Newfoundland Command and left Sydney on September 29 to escort convoy SC.47 as far as Iceland. After two round trips to Iceland, she left St. John's on January 14, 1942, to join SC.64, the first "Newfie-Derry" convoy, and was thereafter employed as an ocean escort on that run principally with EG C-4. She took part in two particularly hard-fought convoy battles: ON.127 (August, 1942); and HX.229 (March, 1943). Her westbound trip after the latter convoy was her last; after a major refit at Lunenburg from April to June, 1943, and work-ups at Pictou, she joined EG W-2 of WLEF, transferring in April, 1944, to W-7 and in October, 1944, to W-1. Late in May, 1944, she underwent a refit at Liverpool, N.S., that included fo'c's'le extension, followed by a month's repairs at Halifax and three weeks' workups in Bermuda in October. She was paid off at Sorel on June 28, 1945, and broken up at Hamilton in 1947.
