The imbalance in President Trump’s treatment of America’s closest trading partners may come from his desire to make Canada the 51st state, some Canadians believe.

Recent pacts with Britain, Europe and Japan mean that autos exported from those countries and regions face lower U.S. tariffs than Canadian vehicles do.

Canada faces a 35 percent tariff on its exports to the United States if it does not reach a trade deal with the Trump administration by Friday.
