Commissioned at Quebec City on June 5, 1941, Buctouche arrived at Halifax on June 12. After working up, she joined Newfoundland Force at St. John's on July 28. On August 26 she left St. John's for Iceland with convoy SC.41, and thereafter escorted convoys to and from Iceland until January, 1942, when Londonderry became the eastern terminus. In June, 1942, she was transferred to WLEF, with which she was to remain until the end of the war except for two months in the summer of 1944, when she was attached to Quebec Force. On June 28, 1944, she was damaged by grounding in Hamilton Inlet, Labrador, but made Pictou on her own for two months' repairs. After the formation of escort groups by WLEF in June 1943, Buctouche served principally with EG W-1. In October, 1943, she commenced a fourth-month refit at Saint John, in the process acquiring an extended fo'c's'le. She was paid off at Sorel on June 15, 1945, and broken up at Hamilton, Ont., in 1949.

Buctouche appeared in a feature length Hollywood war movie titled CORVETTE K225, starring Randolph Scott as the Commanding Officer. She was only filmed from her Starboard side which carried the K225 number for the movie. Her port side carried her actual number K179 as she was still an active duty warship.
