Canada is a country occupying most of northern North America, extending from the Atlantic Ocean in the east to the Pacific Ocean in the west and northward into the Arctic Ocean. It is the world's second largest country by total area, and shares land borders with the United States to the south and northwest. It is a bilingual and multicultural country, with both English and French as official languages at the federal level. Technologically advanced and industrialized, Canada maintains a diversified economy that is heavily reliant upon its abundant natural resources and upon trade—particularly with the United States, with which Canada has had a long and complex relationship.
