Canada is the second largest country by area in the world (after Russia), and the largest in North America. Its only land border is with the United States, which remains the longest undefended land border in the world. This U.S. border is situated at Canada's southern edge, the 49th parallel (or 49 degrees N latitude), though there is also a shorter one with Alaska in the Northwest. Canada is a popular tourist destination, and is one of the world's wealthiest countries. Canada’s landscape is vast and unspoiled, beautiful yet rugged, and contributes to the country’s strong individualistic culture.
