In 1613 he explored the Ottawa river as far as Allumette Island; in 1615, starting from Montreal, he reached the Georgian Bay by way of the Ottawa river, Lake Nipissing and French river, and then by way of Lakes Couchiching and Simcoe and the Trent river system of lakes and streams made his way to Lake Ontario, called by him Entouhoronon.
