HMCS Weyburn was a Royal Canadian Navy Flower-class corvette which took part in convoy escort duties during the Second World War.

[4][5][6] 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.

During her time with the force, she rescued 42 survivors from the torpedoed British merchant Frederika Lensen in the Gulf of St.Lawrence near Anticosti Island.

En route across the Atlantic she picked up three survivors from the British tanker Athelsultan that had been torpedoed southeast of Cape Farewell.

[11] She arrived in the United Kingdom in October and went to Liverpool for a refit that involved adding extra anti-aircraft armaments.

[12] On 22 February 1943, Weyburn struck a mine east of Gibraltar which had been laid by the German submarine U-118 three weeks earlier.

[12] The mine ripped open the portside amidships, splitting the funnel from bottom to top, buckling the decks.
