The Vikings were the first Europeans known to land in what is now called Canada, in what is now Newfoundland, led by the Viking explorer Leif Erikson. They did not stay long, however. In the early 16th century, Europeans started exploring Canada's eastern coast, beginning with John Cabot from England in 1497, and later Jacques Cartier in 1534 from France. Alexander Mackenzie later reached the Pacific coast over land, where captains James Cook and George Vancouver went by sea. The Europeans also traded beaver furs to the First Nations.
