Commissioned at Montreal on June 29, 1941, Kenogami arrived at Halifax on July 4. She served briefly with Halifax Force before arriving at St. John's on August 24 to join convoy all the way to the U.K., as it lost 18 ships in what proved to be one of the worst convoy battles of the war. In February, 1942, after five months' ocean escort duty between St. John's and Iceland, she made her first tip to Londonderry, joining WLEF on her return. She received an extensive refit at Halifax through June and July, and in October resumed her ocean escort duties with EG C-1. The following month she took part in another fierce convoy battle, that of ONS.154, which lost 14 ships. In March, 1943, she made one round trip to Gibraltar, escorting follow-up convoys to the invasion of North Africa. ON May 11 she left 'Derry for the last time, attached to EG B-4 (RN) with convoy ON.183. After a two-month refit at Liverpool, N.S., and workups at Pictou, she joined WLEF's EG W-8. In April, 1944, she transferred to W-4, but in December rejoined W-8 for the balance of the war. During this period she underwent a major refit at Liverpool, N.S., between June and October, 1944, including fo'c's'le extension, followed by three weeks' workups in Bermuda. She was paid off on July 9, 1945 at Sydney and broken up at Hamilton in 1950.
