The Globe and Mail reports in its Saturday edition that U.S. President Donald Trump says he is ending trade talks with Canada and will impose more tariffs within a week in retaliation for Ottawa's digital services tax. The Globe's Adrian Morrow and Robert Fife write that Mr. Trump abruptly announced on Friday that he was walking away from the bargaining table in a seeming bid to increase pressure in the negotiations as the clock ticks down to his and Prime Minister Mark Carney's self-imposed mid-July deadline for a trade deal. "Based on this egregious Tax, we are hereby terminating ALL discussions on Trade with Canada, effective immediately," the President wrote on Truth Social. Canada passed the digital services tax last year with the first payments due on Monday. The tax, modelled on similar levies by European countries, places a 3-per-cent charge on services provided by major technology companies in Canada. U.S. giants such as Amazon, Google, Facebook, Uber and Airbnb are expected to be affected. Mr. Trump claimed in his post that he had "just been informed" about the tax. He said Canada is already "a very difficult Country to TRADE with" because of its protected dairy industry. "We have all the cards," he added.
