HMCS La Malbaie was a revised Flower-class corvette serving with the Royal Canadian Navy during the Second World War, primarily engaged in convoy escort duties in the Battle of the Atlantic. Named after La Malbaie, Quebec, and originally designated as Fort William, her name was changed before commissioning to reflect her Canadian community roots. Constructed by Marine Industries Ltd. in Sorel, La Malbaie was laid down on 22 March 1941, launched on 25 October 1941, and commissioned on 28 April 1942. As part of the revised 1940–41 Flower class, she featured significant design modifications: her water-tube boilers were housed in separate compartments for safety, her forecastle was extended to afford more crew berths, and her bow was given increased flare to improve seaworthiness in heavy seas. These modifications also included heavier armament, with additional depth charge throwers and 20-mm anti-aircraft guns on extended bridge wings, increasing her displacement, draught, and overall length. La Malbaie arrived in Halifax in May 1942 for deployment and soon joined the Western Local Escort Force (WLEF). After initial mechanical issues—though the specific nature of these problems is not detailed—she underwent her first refit at Halifax from August to December 1942. Subsequently, she transferred to the Mid-Ocean Escort Force, serving with Escort Group C-3 as a trans-Atlantic convoy escort from January 1943 until September, then again from after repairs until December 1944. Her service was marked by two significant refits: the first at Halifax and the second at Liverpool, Nova Scotia, to address ongoing mechanical troubles and enhance her operational capabilities. Notably, photographs of La Malbaie taken before her launch served as the model for a 1942 Canadian postage stamp. After the war ended, she was paid off at Sorel on 28 June 1945, transferred to the War Assets Corporation, and sold for scrapping in October 1945. Her hull was broken up in Hamilton, Ontario, in 1951. La Malbaie's service exemplifies the Canadian adaptation of the Flower-class corvette for convoy escort duties and highlights the vessel’s contribution to the Battle of the Atlantic.
