HMCS Arras was one of twelve Battle-class naval trawlers that saw service with the Royal Canadian Navy (RCN). The vessel entered service in 1918 near the end of the First World War and was used for patrolling and escort duties along the Atlantic Coast of Canada. Following the war, Arras was transferred to the Department of Marine and Fisheries where the ship was used as a fisheries patrol vessel. Following the outbreak of the Second World War, the ship re-entered RCN service as a gate vessel. In 1943, the ship was heavily damaged by fire and was broken up in 1957.
