The six physical regions of Canada are: the Cordillera, the Prairies or Plains, the North, the Shield, the Great Lakes and St. Lawrence River and the Atlantic. The Great Lakes and St. Lawrence River section is sometimes divided into two separate physical regions.
The Cordillera region is the western area of Canada that includes British Columbia and the Yukon. Mountains, valleys, plateaus and coastal islands are found in this region. Coastal areas and the southern section of the region are warmer than the northern and inland areas.
The Prairies or Plains region may be called by either name. This region is bordered by the Cordillera on the west, the Shield to the north and east, and the United States in the south. The geography includes flat lands, hills, river valleys and low mountains. The summers are mild, and the winters are very cold.
The North region is also called the Tundra. It is frozen all year. The North includes the northernmost part of the mainland and the islands towards the Arctic. Ice caps, plains and mountains are prevalent.
The Shield is in the center of the country surrounding the Hudson Bay. Most of Canada is in this region. The climate is varied, and the geography includes plains, hills, mountains, highlands, lowlands and numerous bodies of water.
The Great Lakes and St. Lawrence River region is mostly in Ontario and Quebec. It includes the lakes and rivers, hills, escarpments and plains in the southeastern part of Canada. The climate ranges from hot in the summer to cold in the winter.
The Atlantic region includes the islands and peninsulas of Newfoundland, Labrador, Prince Edward Island and Nova Scotia. The Atlantic Ocean greatly influences the weather in this region, and it is often more mild than other regions. Mountains and plains are found here.
