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

The engines produced a total of 2,400 indicated horsepower (1,800 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph).

[3] Chedabucto was armed with a single quick-firing (QF) 4-inch (102 mm)/40 caliber Mk IV gun mounted forward.

[3][5] Chedabucto was ordered on 23 February 1940[6] and her keel was laid down on 24 January 1941 by Burrard Dry Dock Co. Ltd. in Vancouver, British Columbia.

[8] After working up Chedabucto left Esquimalt, British Columbia on 11 November 1941 and arrived at Halifax, Nova Scotia on 17 December.

On 12 January 1942, Chedabucto rescued the crew of the merchant Independence Hall which had run aground on Sable Island.

[7][8] In October, Chedabucto was detailed to escort the cable ship SS Lord Kelvin through the Gulf of St. Lawrence.

[8] On 21 October 1943, Chedabucto was sailing down the Saint Lawrence River to rendezvous with the fire tugboat Citadelle when the minesweeper collided with the cable ship Lord Kelvin near Rimouski, Quebec.

The United States Coast Guard vessel Buttonwood was hailed and attempted to tow the stricken minesweeper closer to shore.
