HMCS Chignecto (hull number MCB 160) was a Bay-class minesweeper operated by the Royal Canadian Navy during the Cold War era. Constructed primarily of wood planking and aluminum framing, the vessel was designed to replace older minesweepers from World War II and shared similarities with the Ton-class minesweepers. The keel was laid down on October 25, 1955, by George T. Davie & Sons Ltd. in Lauzon, Quebec. Launched on November 17, 1956, and commissioned on August 1, 1957, Chignecto was named after a bay situated between Nova Scotia and New Brunswick. The ship measured 152 feet (46 meters) in length, with a beam of 28 feet (8.5 meters) and a draught of 8 feet (2.4 meters). It displaced 390 long tons (approximately 400 tonnes) at standard load, increasing to 412 long tons (around 419 tonnes) at deep load. The vessel's crew complement consisted of 38 officers and ratings. Power was provided by two General Motors 12-cylinder diesel engines driving two shafts, producing 2,400 brake horsepower, which allowed the minesweeper to reach a maximum speed of 16 knots (about 30 km/h). Its operational range was 3,290 nautical miles (around 6,090 km) at a cruising speed of 12 knots. Armament on HMCS Chignecto included a single 40 mm Bofors gun, and it was equipped with minesweeping gear suitable for its role. After commissioning, the vessel was transferred to Canada's Pacific coast, where it served as part of Training Group Pacific. In 1972, the class designation was changed to patrol escorts, reflecting a broader scope of duties. Chignecto remained active until it was paid off on December 19, 1998. The vessel was subsequently sold for scrap to Budget Steel in Victoria, British Columbia, and was dismantled in 1999. Throughout its service, HMCS Chignecto played a vital role in training and patrol operations, contributing to Canada's naval readiness during the Cold War period.
