A number of Sir James Dunn's Canadian investments were in Northern Ontario mining ventures and he began a business relationship with Algoma Steel, a company in Sault Ste. Marie, Ontario. Founded by Francis Clergue, Algoma Steel had been taken over by Philadelphia, Pennsylvania investors after its 1903 bankruptcy. Overly dependent on the production of rail tracks, the steel company suffered through numerous problems and in 1908 Dunn had partnered with a British group of investors who included Robert Fleming to cooperate with an American consortium to form the Lake Superior Investment Co. to acquire Algoma Steel. Although Dunn's role at the time was important, he was still only a minority player and the American investors had control.
