HMCS Lachine was a Bangor-class minesweeper of the Royal Canadian Navy that served during the Second World War.

Following the war a proposed transfer to the Royal Canadian Mounted Police as Starnes was cancelled, and the ship was instead sold for conversion to a salvage tug in 1945.

[3] This may have been due to all the additions made during the war with the installation of ASDIC, radar and depth charges.

Lachine was of the diesel-powered version, being equipped with a 9-cylinder diesel engine driving two shafts that produced 2,000 brake horsepower (1,500 kW).

[4] The Canadian diesel-powered Bangors were armed with a single quick-firing (QF) 12-pounder 12 cwt gun mounted forward.

Her keel was laid down by Davie Shipbuilding at Lauzon, Quebec on 27 December 1940, and launched on 20 June 1942.

Lachine was commissioned into the Royal Canadian Navy at Quebec City on 20 June 1942 with the pennant number J266.
