【正确答案】 Canada extends up north into the Arctic Circle to the North Pole. The north is a scarcely populated area of ice and oceans which is sometimes called "the Land of the Midnight Sun". This region is currently divided into three huge administrative territories—the Yukon, the Northwest Territories and Nunavat. And most of the inhabitants are aboriginal peoples. The traditional economy in this region was based on hunting and trapping animals for food and pelts, but now oil and gas deposits are also being developed.
