Geography

Covering most of the northern part of the North American continent and with an area larger than that of the United States, Canada has an extremely varied topography. In the east the mountainous maritime provinces have an irregular coastline on the Gulf of St. Lawrence and the Atlantic. The St. Lawrence plain, covering most of southern Quebec and Ontario, and the interior continental plain, covering southern Manitoba and Saskatchewan and most of Alberta, are the principal cultivable areas. They are separated by a forested plateau rising from Lakes Superior and Huron.
