The Globe and Mail reports in its Friday, Jan. 31, edition that U.S. President Donald Trump announced plans to impose 25-per-cent tariffs on goods from Canada and Mexico, effective Saturday. The Globe's Steven Chase writes that Canadian oil, however, may be exempt, with a decision expected by the end of Thursday, as Canada supplies about 60 per cent of U.S. oil imports. Mr. Trump has been griping about illegal migration and smuggling of fentanyl into the United States from Canada and Mexico, as well as imbalances in trade. Mr. Trump said the tariffs may rise over time. Natural Resources Minister Jonathan Wilkinson warned an American audience Wednesday that tariffs on Canadian oil would drive up gasoline prices in the U.S. Midwest by up to 75 cents a gallon -- an example of how heavily the United States relies on its northern neighbour for energy and critical minerals. The Canadian government says the U.S. trade deficit with Canada -- where Americans buy more from Canada than vice-versa -- is the result of large petroleum exports to the U.S. Were Mr. Trump to include Canadian oil in his tariff action, it would drive up gasoline prices in the United States despite his campaign pledge to lower them.
