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.
