Construction of the railway began in June 1875, Fort William began to grow, but very slowly. It would take the federal Department of Public Works, and later the Department of Railways and Canals, seven years 1875-1882 to build the Thunder Bay Branch from Fort William to Winnipeg.By 1883-84 it was clear to all but the residents of Port Arthur that the Montreal-based Canadian Pacific Railway syndicate, in collaboration with the Hudson's Bay Company, preferred the low lying lands along the lower Kaministiquia River to the rocky shores of Port Arthur, and the Company subsequently consolidated all its operations there, erecting rail yards, coal handling facilities, grain elevators and a machine shop.
