Explanation:

Canada is a country in North America. Canada, with an area of 9,985 million square kilometers, is the world's second largest country on the surface, after Russia. With a population of about 37 million, it is one of the world's most sparsely populated countries.  

Canada borders the Pacific Ocean to the west and the Atlantic Ocean to the east and has land borders with the US to the west (Alaska) and south. In the northeast, the sea border goes to Greenland with only a few miles distance between the land masses at the nearest place. To the east, Canada has a sea border with the smaller French archipelago of Saint-Pierre and Miquelon. Northern Canada extends almost as far as the North Pole and forms part of the Arctic.
