Flows of migrants and seizures of drugs at the two countries’ border are vastly different. U.S. customs agents seized 43 pounds of fentanyl at the Canadian border during the last fiscal year, compared with 21,100 pounds at the Mexican border.

Canada is the top export destination for 36 U.S. states. Nearly $3.6 billion Canadian (US$2.7 billion) worth of goods and services cross the border each day. About 60% of U.S. crude oil imports are from Canada, and 85% of U.S. electricity imports as well.

Canada is also the largest foreign supplier of steel, aluminum and uranium to the U.S. and has 34 critical minerals and metals that the Pentagon is eager for and investing for national security.
