Transcona 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).

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

[7] After commissioning, Transcona escorted HMCS Provider to Halifax, Nova Scotia and remained at the shipyard there from 22 December 1942 to 6 March 1943 due to engine defects.

Once those were repaired, the minesweeper performed her workups and was assigned to the Western Local Escort Force (WLEF) in April.

On 23 December, with sister ship Clayoquot and the frigate Kirkland Lake, Transcona sailed from Halifax on a pre-convoy escort submarine sweep of the swept channel near the Sambro Light Vessel.

[7] On 1 September 1945, Transcona was transferred to the Royal Canadian Mounted Police Marine Division and renamed French.

[9] The vessel was turned over to the Crown Assets Corporation, sold for scrap on 2 February 1961 and broken up at LaHave, Nova Scotia later that year.
