HMCS Vancouver was a Flower-class corvette that served with the Royal Canadian Navy 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.

Notably, the 1940–41 program featured water-tube boilers, which, while less responsive, offered greater reliability in maintaining a consistent supply of steam.

On 20 June 1942, she escorted SS Fort Camosun to Victoria after she had been torpedoed by the Japanese submarine I-25.

After returning to Canada she remained with Esquimalt Force until 24 February 1943 when she was placed again under American control as part of D-Force until the end of May.

[10] She arrived at Halifax, Nova Scotia 25 March, having made the journey with HMCS Dawson.

After workups in Bermuda she returned to service with WLEF as part of group W-1 and remained with them until the end of the war.
