HMCS Halifax was a Royal Canadian Navy revised Flower-class corvette 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.

[5] During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design.

They also came with heavier secondary armament with 20-mm anti-aircraft guns carried on the extended bridge wings.

[9] In July 1942 she transferred to Halifax Force as an escort to tanker convoys leaving Aruba.

After workups in Bermuda, she briefly joined Halifax Force in January 1945 before transferring back to MOEF as a member of C-9.

[10] After the cessation of hostilities, Halifax was paid off from the RCN on 12 July 1945 at Sorel, Quebec.

She was transferred to the War Assets Corporation and sold later that year as the mercantile (salvage vessel) Halifax.
