Manitoulin Island Manitoulin Island /ˌmænɪˈtuːlɪn/ (originally Ekaentouton) is a Canadian lake island in Lake Huron, in the province of Ontario. It is the largest freshwater lake island in the world.[1] In addition to the historic Anishinaabe and European settlement of the island, archeological discoveries at Sheguiandah have demonstrated Paleo-Indian and Archaic cultures dating from 10,000 BC to 2000 BC.[2]
