Trump’s fight with Canada over NAFTA faces new hurdles: President Donald Trump’s effort to force Canada into signing on to a new NAFTA on his terms is facing new hurdles thanks to growing opposition at home to his threat to proceed without the U.S.’s northern neighbor. The president has threatened to leave Canada out of a new trade deal already negotiated with Mexico, but without congressional support he lacks leverage to force Ottawa to make concessions in talks that are due to resume Wednesday.
