Before being completed, the ship was transferred to the Royal Canadian Navy, renamed HMCS Orangeville and used as a convoy escort for the rest 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.

[8] Renamed Orangeville for the town in Ontario, the corvette was commissioned into the Royal Canadian Navy on 24 April 1944 with the pennant number K491.

[9] In June 1951, Hsi Lin was taken over by the Nationalist Chinese government, rearmed and renamed Te An and remained in service until being discarded in 1967.
