Transferred to the Royal Canadian Navy before completion, the ship was renamed HMCS Copper Cliff and saw service as a convoy escort for the remainder of the war.

Though the Admiralty would have preferred Loch-class frigates, the inability of many small shipyards to construct the larger ships required them to come up with a smaller vessel.

This powered one vertical triple expansion engine that drove one shaft, giving the ships a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph).

[2] The ships carried 480 tons of oil giving them a range of 6,200 nautical miles (11,500 km; 7,100 mi) at 15 knots (28 km/h; 17 mph).

[4] The Type 147B was tied to the Squid anti-submarine mortar and would automatically set the depth on the fuses of the projectiles until the moment of firing.

[9] The corvette, renamed Copper Cliff after a suburb of Sudbury, Ontario, was commissioned into the Royal Canadian Navy on 25 February 1944 with the pennant number K495.

In June 1945, Copper Cliff returned to Canada, stopping in Halifax, before continuing on to her final destination of Esquimalt, British Columbia.
