HMCS Shediac was a Flower-class corvette of the Royal Canadian Navy during the Second World War.

[3][4][5] The "corvette" designation was created by the French for classes of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

She was laid down by Davie Shipbuilding & Repairing Co. Ltd. at Lauzon, Quebec on 5 October 1940 and launched on 29 April 1941.

Her second major overhaul began in mid-June 1944 and lasted until mid-August, taking place at Vancouver, British Columbia.

[12] Beginning in July 1942 Shediac was assigned to the Western Local Escort Force (WLEF).

[12] After returning from her first major refit, Shediac rejoined WLEF as a member of escort group W-8.
