The Canadian Shield also called the Laurentian Plateau, is a massive geological shield covered by a thin layer of soil that forms the nucleus of the North American or Laurentia creation. It is an area mainly covered by igneous rock which relates to its long volcanic history. It has a deep, common, joined bedrock region in eastern and central Canada and stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada; it also extends south into the northern reaches of the United States. Population is scarce, and industrial development is minimal, although the region has a large hydroelectric power potential.
