where is the canadian shield on the map
Canadian Shield The Canadian Shield, also called the Laurentian Plateau, or Bouclier canadien (French), is a large area of exposed Precambrian igneous and high-grade metamorphic rocks (geological shield) that forms the ancient geological core of the North American continent (the North American Craton or Laurentia). Composed of igneous rock resulting from its long volcanic history, the area is covered by a thin layer of soil.[3] With a deep, common, joined bedrock region in eastern and central Canada, it 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. Human population is sparse, and industrial development is minimal,[4] while mining is prevalent.
Military history of Canada Operation Impact is the name of Canada's contribution to the military intervention against the Islamic State of Iraq and the Levant that began in September 2014.[312] The first Canadian airstrike against an Islamic State target occurred on 2 November. It was reported that CF-18s successfully destroyed heavy engineering equipment used to divert the Euphrates River near the city of Fallujah.[313] In October, then Prime Minister designate Justin Trudeau informed President Barack Obama that Canada intended to withdraw its fighter aircraft, while keeping its ground forces in Iraq and Syria.[314]
