Étienne Brûlé
Born in France in 1595, arrived in Quebec in 1608. With a genius for exploration, Brûlé, from Lake Huron, thence to Lake Simcoe and southward made the Humber his route to Lake Ontario in 1615. This tablet commemorates his journey of discovery by the pathway of the Humber, and honours the name of Étienne Brûlé, the first white man to see Lake Ontario.
