First Voyage: 1603
In 1603 he went on his first voyage to Canada, as geographer on a fur-trading expedition. He travelled up the Saguenay, St. Lawrence, and Richelieu rivers and used the information he collected to make a very accurate map of Canada from Hudson Bay in the north down to the Great Lakes.
