In 1909 the Government of Canada ordered an icebreaking passenger steamship for service in the Northumberland Strait to connect the ports of Charlottetown and Georgetown on Prince Edward Island with the mainland port of Pictou.  She was commissioned in 1910 by then Governor General, Albert Grey as CGS Earl Grey (Canadian Government Ship Earl Grey).  She was sold in 1914 to Imperial Russia, an ally during World War I. The ship, christened Kanada and later Fyodor Litke, operated in the Arctic until 1958.
