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

[3][4][5] 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.

Her second major overhaul began in June 1943 at Liverpool, Nova Scotia, and was completed at Halifax in mid-September.

[11] After arriving at Halifax 23 May 1942, Woodstock was initially assigned to the Western Local Escort Force (WLEF).

While performing duties associated with Operation Torch, Woodstock sank the motor torpedo boat MTB 105 250 miles northwest of the Azores.

[11] Woodstock returned to Canada in March 1943 and in April joined the Mid-Ocean Escort Force (MOEF).

Late in June she was sent to join MOEF group C-4 for one round trip across the Atlantic before departing for a refit.

[11] After returning from refit Woodstock rejoined MOEF group C-4 until April 1944 when she was made part of Operation Neptune, the naval component of the Allied invasion of Normandy.

[11] After completing her refit, Woodstock departed for the west coast on 18 October 1944 and arrived at Esquimalt in November.
