Canada maintains that its efforts to evade American tariffs on steel and aluminum, and threatened tariffs on cars, are on a "separate track" from the ongoing NAFTA talks. I don't think we're going to get a NAFTA deal any time soon. Would a renegotiated NAFTA lift damaging steel and aluminum tariffs and shut down threats of future car tariffs? In return, future car tariffs won't apply to shipments below the mutually-acceptable level. Otherwise, Canada might need Congress to ride to its rescue to block either the car tariffs or Trump's withdrawal from NAFTA altogether.
