President Donald Trump's new tariff orders against Canada, Mexico and China all contain clauses suspending a duty-free exemption for low-value shipments below $800 that is widely seen as a loophole that has allowed shipments of fentanyl and its precursor chemicals into the United States.

Trump argues the tariffs are necessary to “protect Americans” and to curb the export of fentanyl. But for our North American neighbors, the move sparked an undeniable sense of betrayal.

U.S. President Donald Trump has declared a trade war on Canada, prompting the federal government, provinces and territories to launch their own countermeasures to hit back at the American economy.Trump imposed a 25 per cent tariff on virtually all goods from Canada and a lower 10 per cent tariff on Canadian energy products.
