HMCS Longueuil (K672)

HMCS Longueuil was a River-class frigate that served in the Royal Canadian Navy from 1944-1945.

Named after Longueuil, Quebec, she was built by Canadian Vickers Ltd., Montreal. She was commissioned into the RCN at Quebec City on 18 May 1944 with the pennant K672.

She arrived at her homeport of Halifax, Nova Scotia and undertook work up training at Bermuda under the command of Lt. Cdr. M.J. Woods, RCNVR, her only commanding officer.

Her first convoy escort took place with Convoy HX.302 which departed New York City on 4 August 1944 and arrived at Liverpool on 17 August. Longueuil was deployed with the convoy from 8 August until 13 August.

With victory in Europe seemingly imminent, the RCN deployed Longueuil to Esquimalt in June 1945 in preparation for Operation Downfall, the Allied invasion of Japan. Longueuil joined the RCN's Pacific Fleet only weeks before the Surrender of Japan following the atomic bombings of Hiroshima and Nagasaki.

She was paid off from the RCN on 31 December 1946 and the decision was made to dismantle her armaments and scuttle her to form a breakwater in Kelsey Bay, British Columbia in 1947.
