By the 1850s, the Province of Canada began to take an interest in its western extremity. Discovery of copper in the Keweenaw Peninsula of Michigan had prompted a national demand for mining locations on the Canadian shores of Lake Superior. In 1849, French-speaking Jesuits established the "Mission de l'Immaculée-Conception" (Mission of the Immaculate Conception) on the Kaministiquia to evangelize the Ojibwe. The Province of Canada negotiated the Robinson Treaty in 1850 with the Ojibwa of Lake Superior. As a result, an Indian reserve was set aside for them south of the Kaministiquia River. In 1859–60, the Department of Crown Lands surveyed two townships (Neebing and Paipoonge) and the Town Plot of Fort William for European-Canadian settlement.
