An Asiatic people, the Inuits arrived in Canada during the last Ice Age, but some time after the Indians. Until quite recently, they led a nomadic existence, sheltering in igloos, the ice-block domes that are peculiar to northern-central Canada, and structures made of stones, bones, driftwood, sods and skins.
