lol the mexico border wall would be stupid expensive, just imagine how much a canadian border wall would cost. not even remotely feasible
from wikipedia: The Canada–United States border, officially known as the International Boundary, is the longest international border in the world, shared between Canada and the United States of America, the second and third largest countries by area respectively. The terrestrial boundary (including small portions of maritime boundaries on the Atlantic, Pacific, and Arctic coasts, as well as the Great Lakes) is 8,891 kilometres (5,525 mi) long, including 2,475 kilometres (1,538 mi) shared with Alaska. Eight Canadian provinces and territories (Yukon, British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, and New Brunswick), and thirteen U.S. states (Alaska, Washington, Idaho, Montana, North Dakota, Minnesota, Michigan, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine) are located along the border.
