What Continent is Canada in?

Is Canada part of USA or not?

Canada occupies half of the North American continent and is the second largest country in the world, after Russia. It is bordered to the NORTH by the Arctic Ocean, to the NORTHWEST by Alaska(USA), to the SOUTH by the United States, to the EAST by the Atlantic Ocean, and to the WEST by the Pacific Ocean.

In addition to the Atlantic and Pacific coasts, Canada also faces the Arctic Ocean, making it the country with the longest coastline in the world. In the north, the Arctic islands are located 800 km from the North Pole. Due to the harsh climate of the north, only 12% of the land is arable. It follows that the population, consisting of 30 million inhabitants, lives mostly on the southern border of the country where the climate is milder, in a long and thin strip that runs from the Atlantic to the Pacific.
