Comments from U.S. President Donald Trump following his departure from the G7 summit in Kananaskis, Alta., are casting doubt on new progress in trade talks with Canada. Trump said Canada is 'going to have to pay a lot of tariffs on things.

Trump railed against former Prime Minister Justin Trudeau after that Group of Seven summit and threatened to yank the United States from a joint statement. The leaders fought over tariffs on steel and aluminum.

Donald Trump has signed a trade agreement with the UK that will slash tariffs on goods from both countries but does not include an agreement on steel.
