Why did Samuel de Champlain sail?

He wanted to discover a water route across the American continent!

He was the founder of Quebec with out him there would be no Quebec LMAO

He was sent by King Henri IV and set up trading posts. He set up the posts Port Royal, and Kebec (Algonquin Word for Quebec, where the river narrows).

I think that he was sent mostly to make settlements for France, to gain more land.
