The Globe and Mail reports in its Saturday edition that the G7 meeting in Kananaskis, Alta., is happening against the backdrop of massive upheaval in international trade caused by U.S. President Donald Trump's combative tariffs. The Globe's Mark Rendell writes that experts do not expect the group meetings, which form the core of every G7 program, to focus much on the trade disputes Mr. Trump has with every other leader around the table. Canadian officials have already indicated there likely will not be a joint communiqué at the end of the meeting, perhaps to avoid exposing discord and antagonizing the U.S. President. Instead, the real action will take place on the sidelines of the summit. "The U.S. ... seems very hostile to attempts by other countries to band together or have some kind of collective agreement," said Queen's University's Nicolas Lamp. Canada avoided Mr. Trump's "reciprocal" tariffs and the baseline 10-per-cent tariff. But it is still being squeezed by levies on steel, aluminum, automobiles and other goods that do not meet the continental free-trade agreement's rules of origin. And the U.S. has continued to ratchet up the pressure doubling tariffs on steel and aluminum to 50 per cent last week.
