RMS Empress of Britain was a transatlantic ocean liner built by Fairfield Shipbuilding at Govan on the Clyde in Scotland in 1955–1956[1] for Canadian Pacific Steamships (CP). This ship – the third of three CP vessels to be named Empress of Britain[2] – regularly traversed the trans-Atlantic route between Canada and Europe until 1964, completing 123 voyages under the Canadian Pacific flag.
