HMCS Champlain was a Thornycroft S-class destroyer, formerly HMS Torbay built for the Royal Navy in 1917-19. This ship, along with her sister Toreador, were donated by the British Government to Canada in March 1928 to replace their two existing destroyers, HMCS Patrician and HMCS Patriot. At the same time the Canadian Government commissioned the construction of two further destroyers, Saguenay and Skeena. During the 1930s the Champlain served on the east coast of Canada alongside the Saguenay. The ship and her sister HMCS Vancouver were paid off and broken up in 1937.
