RMS Empress of Canada was an ocean liner built in 1920 for the Canadian Pacific Steamships (CP) by Fairfield Shipbuilding & Engineering Company at Govan on the Clyde in Scotland.

In 1920, Canadian Pacific Steamships ordered a new ship to be built by Fairfield Shipbuilding & Engineering Company at Govan near Glasgow in Scotland.

The ship was launched on 18 August 1920 with a notable speech by the general manager of the Canadian Pacific Ocean Services, Ltd., Sir Thomas Fisher, who noted the approximately $6,800,000 price compared to a pre-war cost of about $2,200,000 and cost of operation that had risen at least 350 per cent, which had forced first class fares from $76 to $202 (based on a $4 to the pound sterling) and predicted dire consequences for shipping and the British Empire.

[6][7] On 5 June 1931, as the Empress of Canada sailed in the Pacific Ocean between Honolulu and Yokohama, 42-year-old Filipino passenger Graciano Bilas killed two people and wounded 29 others in a mass stabbing aboard the ship.

[9] On 14 June 1940 the ship was part of the troop convoy US.3 consisting of the liners Andes, Aquitania, Empress of Britain, Mauretania and Queen Mary, which sailed from Australia en route to the Clyde and was met to the west of Gibraltar by a naval force led by the battlecruiser HMS Hood.

On 14 March 1943 at 01.00 am, while en route from Durban, South Africa to Takoradi carrying Italian prisoners of war along with Polish and Greek refugees,[10] Empress of Canada was torpedoed at midnight and sunk by the Italian submarine Leonardo da Vinci approximately 400 miles (640 km) south of Cape Palmas off the coast of Africa.
