Built by Burrard Drydock Company and commissioned at Vancouver, British Columbia, on April 8, 1941, the Flower Class Corvette Chilliwack arrived at Halifax, Nova Scotia, on June 19, was assigned to Newfoundland Command in July, and for the rest of the year escorted convoys between St. John’s, Newfoundland, and Iceland. Early in February, she escorted convoy SC.67, her first transatlantic convoy, and was thereafter employed almost continuously as an ocean escort until November 1944. From June 1942 onward she was a member of Escort Group C-1, and during this period escorted 3 convoys around which epic battles were fought: SC.94 (August 1942); ONS.154 (December 1942); and ON.166 (February 1943). In addition, Chilliwack assisted in sinking 2 U-boats: U-356 (when escort to ONS.154, December 27, 1942); and U-744 (when escort to HX.280, March 6, 1944). In the course of a major refit from April to October 1943 at Dartmouth, Nova Scotia, she acquired her long forecastle. Assigned on December 4, to Escort Group W-8, Western Escort Force, she left for a month’s workups in Bermuda. Reassigned in April 1945 to Halifax Force, she was temporarily loaned to Escort Group C-1 the following month for 1 final round trip to Londonderry, North Ireland. Paid off July 14 and laid up at Sorel, Quebec, Chilliwack was broken up at Hamilton, Ontario in 1946.
