Cockburn Island

Cockburn Island is an island and municipality in the Canadian province of Ontario, located in the Manitoulin District. It is separated from the westernmost point of Manitoulin Island by the Mississagi Strait, and from Michigan's Drummond Island by the False Detour Channel.The island is incorporated as and coterminous with the municipal Township of Cockburn Island. With an official population of zero in the Canada 2011 Census, and populations varying between zero and ten people in the previous three censuses, Cockburn Island is the least populated incorporated municipality in Canada. However, the population grows significantly in the summer, as an estimated two to three hundred people maintain cottages and summer homes on the island. Township offices are located on the mainland in Thessalon in Algoma District.Until 2010, a small portion of the north-west side of the island was taken up by the Cockburn Island 19 Indian reserve, which had no permanent population — this was heritage land belonging to a First Nation whose primary community is located on Manitoulin Island. On January 2, 2010, it was dissolved and added to Cockburn Island Township.
