Canada-U.S. Border

The Canada-U.S. border is the longest international border in the world, spanning approximately 5,525 miles. It separates Canada's northern landmass from the United States, running from the Atlantic Ocean to the Pacific Ocean and inland to the Arctic. The border is characterized by various natural features like rivers and lakes, as well as man-made borders and checkpoints. It facilitates trade, travel, and security between the two nations. Despite being a secure boundary, it’s also highly accessible for citizens, businesses, and tourism, reflecting a close, cooperative relationship rooted in shared history and economic ties.
