HMCS Chilliwack was a Flower-class corvette who served with the Royal Canadian Navy during the Second World War.

[3][4][5] The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

At Burrard Dry Dock in North Vancouver, British Columbia she was laid down on 3 July 1940.

She was assigned to Newfoundland Command in July and spent the rest of the year escorting convoys between St. John's and Iceland.

In February 1942 she began work as an ocean escort, a position she continued with few interruptions until November 1944.

[11] Chilliwack participated in the battle for convoy SC 67 before assignment to Mid-Ocean Escort Force (MOEF) group C1 in June 1942.
