The Globe and Mail reports in its Saturday edition that U.S. President Donald Trump vowed to increase his use of sector-based duties and others after the Supreme Court ruled against a swath of his existing tariffs on Friday, raising new risks for a Canadian economy. The Globe's Jason Kirby writes that before the administration can impose such tariffs, however, the Commerce Department must conduct a formal investigation and produce a report on its findings. Nine additional national security investigations have been launched, of which four were scheduled to have been completed, though no final reports or tariff announcements have been issued. They cover the semiconductor, pharmaceutical, critical minerals, and commercial aircraft and jet engine industries. The remaining investigations, still under way, cover polysilicon (used in the solar industry), drones, wind turbines, medical equipment and robotics and industrial machinery. The Trump administration has been waiting until after the court ruling "to deliver a barrage of new sectoral duties," wrote Michael Gregory, deputy chief economist at Bank of Montreal, in a note. "There are already reports of other industries seeking the cover of 'national security' tariffs."
