OTTAWA, CANADA — Nearly 50,000 people in Canada died of an apparent opioid overdose from January 2016 to June 2024, with fentanyl playing an increasingly prominent role in fatalities, the national health agency said Monday. The prevalence of fentanyl in Canada has drawn additional attention after U.S. President-elect Donald Trump cited the drug as part of his justification to impose sweeping tariffs on Canadian imports. Trump has accused Ottawa of not doing enough to stem the flow of fentanyl into the United States and said his promised 25% tariff would remain in place until Canadian authorities address the problem.
