Steam navigation on the Muskoka Lakes began in 1866, when the paddle vessel "Wenonah" went into service. Built at Gravenhurst, she was owned by A.P. Cockburn (1837-1905), who served as the federal member of parliament for Muskoka, 1872-82, and for North Ontario, 1882-87. The "Wenonah" was the first of a line of ships known after 1872 as the Northern Lakes Navigation Company, and after 1949 as the Muskoka Lakes Line. Its ships were among many which contributed to the early and rapid development of Muskoka as a lumbering and resort region. The steamboat gradually gave way to the automobile, and the last two, "Segwun" (1887) and "Sagamo" (1906) ceased operation in 1958.
