The Globe and Mail reports in its Saturday edition that Donald Trump's threatened 35-per-cent tariffs on Canadian goods would most likely only apply to those traded outside the USMCA, currently subjected to 25-per-cent tariffs, a U.S. administration official says. A triple-bylined item led by Adrian Morrow says that higher tariffs, set to start on Aug. 1, are not expected to cover goods traded under USMCA or oil, gas and potash traded outside the deal, which have been hit with 10-per-cent tariffs. The official, however, cautioned that the President had not yet made a decision and no final paper had been drafted on the subject. The continuing uncertainty capped a week in which Mr. Trump failed to fulfill his promise of "90 deals in 90 days," and instead issued a flurry of largely formulaic letters -- containing capitalizations and some typos -- threatening a range of new tariffs against dozens of countries. The President set Aug. 1 as the new deadline for deals or else the higher tariffs will take effect. The President's letter complains about fentanyl entering the U.S. from Canada, retaliatory tariffs that Ottawa imposed earlier this year, and the Canadian supply management system for dairy and eggs.
