Surrender of Indian Lands
By treaties made in 1798, 1815 and 1818, the Indian tribes surrendered the ancient country of the Hurons lying north and west of Lake Simcoe. From this area grants were made, in fulfillment of earlier pledges to militia veterans, to children of Loyalists, and to many retired officers and discharged soldiers and seamen.
