Saugeen Tract Agreement, registered as Crown Treaty Number 451⁄2, was signed August 9, 1836 between the Saugeen Ojibwa and Ottawa and the government of Upper Canada. Conducted on the Manitoulin Island, Sir Francis Bond Head used this occasion for the provincial government's annual distribution of gifts to the Ojibwa and Ottawa of the Saugeen Peninsula (Bruce Peninsula) to negotiate the treaty. In exchange for 1.5 million acres (6,070 km²) of land, the Ojibwa and Ottawa of Saugeen received only a promise to assist and protect Indians who took up residence on the Bruce Peninsula.
