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

[2][3][4] 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.

As SS West York, she was towing the decommissioned HMCS Assiniboine when the towline parted and the destroyer was wrecked on 7 November 1945 off Prince Edward Island.

[11] By 1947, she had her steam reciprocating engine replaced by diesel power and sailed under Moroccan registry as the Moulay Bouchaib.

Holed and with her mooring lines carried away, Federal Express careened into the Danish Hilda Maersk and sank in 30 minutes.
