Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres (3.85 million square miles), making it the world’s second-largest country by total area and the fourth-largest country by land area. Canada’s southern border with the United States is the world’s longest bi-national land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Its capital is Ottawa, and its largest metropolitan areas are Toronto, Montreal and Vancouver.
Canada is a federal parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II being the head of state. The country is officially bilingual at the federal level. It is one of the world’s most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Its advanced economy is the tenth-largest in the world, relying chiefly upon its abundant natural resources and well-developed international trade networks. Canada’s long and complex relationship with the United States has had a significant impact on its economy and culture.
