HMCS Sans Peur was an armed yacht that served with the Royal Canadian Navy (RCN) during World War II on both coasts. The vessel was constructed as a yacht in 1933 for Ernest G. Stanley at the John I. Thornycroft & Company yard in Woolston, Southampton, United Kingdom and initially named Trenora. It was sold in the 1930s to George Sutherland-Leveson-Gower, 5th Duke of Sutherland who renamed it Sans Peur. The yacht was taken over by the RCN in 1939 and used for anti-submarine patrols and training duties on the British Columbia Coast. In 1944, Sans Peur was brought east to Nova Scotia as a training ship.
