General description. Covering most of the northern part of the North American continent and with an area larger than that of the United States

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.

Westward toward the Pacific, most of British Columbia, the Yukon, and part of western Alberta are covered by parallel mountain ranges, including the Rockies. The Pacific border of the coast range is ragged with fjords and channels. The highest point in Canada is Mount Logan (19,850 ft; 6,050 m), which is in the Yukon. The two principal river systems are the Mackenzie and the St. Lawrence. The St. Lawrence, with its tributaries, is navigable for over 1,900 mi (3,058 km).

Canada is a federation of ten provinces (Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, Quebec, and Saskatchewan) and three territories (Northwest Territories, Yukon, and Nunavut), each with its own capital city. Canada is the largest country (9.9 million square km) in the Western hemisphere and the second-largest country in the world.

Formally considered a constitutional monarchy that is also a parliamentary democracy and a federation, Canada is governed by its own House of Commons. While the governor-general is officially the representative of Queen Elizabeth II, in reality the governor-general acts only on the advice of the Canadian prime minister.

The capital city of Canada is Ottawa, Ontario. The national holiday in Canada is Canada Day which is on the 1^st of July. The national symbol of Canada is the maple leaf. Canada has two official languages, French and English. Toronto is the largest city of Canada. It is known for its cleanliness and low crime rate.

In recent years, Canada has introduced some of the world's most liberal social policies. Medical marijuana for the terminally or chronically ill was legalized in 2001; the country began legally dispensing marijuana by prescription in July 2003. In 2003, Ontario and British Columbia legalized same-sex marriage; and more provinces and territories followed in 2004. In July 2005, Canada legalized gay marriage throughout the country, becoming one of four nations (along with Belgium, the Netherlands, and Spain) to do so.
