MS Norgoma was a Canadian package freighter and passenger ferry, that could also transport automobiles on a limited basis. Originally constructed as a steam-powered ship in 1950, SS Norgoma primarily sailed the route from her home port of Owen Sound to Sault Ste. Marie, providing a five-day round trip, once a week, serving isolated communities along the north shore of Lake Huron. After conversion to a motor ship, Norgoma was transferred to the popular Manitoulin Island ferry route between Tobermory and South Baymouth along with her sister ship SS Norisle, replacing the smaller ferry, MS Normac, on that route.Norgoma, owned by Owen Sound Transportation Company Limited, was built at the Collingwood shipyards in 1950. She replaced the SS Manitoulin, which was retired in 1949.Norgoma travelled mainly on the North Channel route until 1963. Improvements to Ontario's highways, such as the Trans-Canada Highway (Georgian Bay Route) completed in 1962, brought about stiff competition for the company. In that year a 60-kilometer road was constructed to Killarney, the first port of call for the steamer. At the same, increased traffic on the Manitoulin Island - Tobermory route demanded a greater automobile capacity than her sister ships SS Norisle and MS Normac could handle.
