The Globe and Mail reports in its Wednesday, Nov. 23, edition that U.S. exporters love Canada. The Globe's Barrie McKenna writes that it is the single largest market for U.S. goods and services, accounting for 15 per cent of everything the United States sells to the world. There is a high degree of integration within industries such as autos, aerospace and food products. Nearly 66 per cent of products and services that cross the Canada-U.S. border are inputs for final products. Car parts typically cross the border multiple times before a vehicle reaches the consumer. About 13 per cent of imports from Canada go into U.S. products sold to third countries. President-elect Donald Trump apparently wants to target Canadian lumber and livestock exports. Mr. McKenna notes that making Canada pay may not repatriate U.S. jobs. The United States has already effectively removed lumber from NAFTA, forcing Canada into a managed trade deal. The last thing the U.S. lumber industry wants is for lumber to be put back in NAFTA. Perpetuating or increasing those restrictions will also make lumber -- and U.S. homes -- more expensive. The same applies to livestock.
