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.

Sault Ste. Marie is a city in Ontario, Canada. The third-largest city in Northern Ontario after Sudbury and Thunder Bay, it is located on the St. Mary's River on the Canada–US border. To the southwest, across the river, is the United States and the Michigan city of the same name. The two cities are joined by the Sault Ste. Marie International Bridge, which connects Interstate 75 on the Michigan side to Huron Street on the Ontario side. Shipping traffic in the Great Lakes system bypasses the Saint Mary's Rapids via the American Soo Locks, the world's busiest canal in terms of tonnage that passes through it, while smaller recreational and tour boats use the Canadian Sault Ste. Marie Canal.
