U.S. President Donald Trump's successive announcements of deals setting baseline tariffs on the European Union and Japan are prompting questions about whether they're a road map for Canada to follow in trade talks.

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.

The United States may not reach a negotiated trade deal with Canada, U.S. President Donald Trump said on Friday, suggesting his administration could set a tariff rate unilaterally.
