The S.S. "Manitoulin" continued to navigate the Turkey Trail of the North Channel from Owen Sound until its honorable and well-deserved retirement in 1949. "Turkey Trail" was by then the affectionate term for the North Channel route, some say because a large number of turkeys were transported from Manitoulin's island ports along the north shore during the years immediately following World War II, and others because the ships serving the isolated ports of the North Channel wandered across the channel like turkeys. In 1950, the 60-year-old S.S. "Manitoulin" was replaced by the S.S. "Norgoma"—the name being derived from "North (District of) Algoma"—again designed and built by the Collingwood Shipyards Limited. Unlike the "Norisle", the S.S. "Norgoma" was designed primarily as a package freighter and passenger steamship, specifically for the Georgian Bay and North Channel route—but, reflecting the practicality of its Grey County ownership, like its predecessors the "Norgoma" could also transport cars (if only a limited number of them).
