The ongoing trade dispute between the United States and Canada shows no signs of easing, as former President Donald Trump unveils his latest countermeasures.

Trump’s new tariffs come in response to increased electricity prices imposed by the provincial government of Ontario on power exported to the U.S. Having previously warned of retaliation, Trump is now making good on his promise.

Trump Announces Tariff Hikes on Canadian Imports

Taking to his social media platform, Truth Social, Trump outlined his plan to strike back against Canada.

He wrote: “Based on Ontario, Canada, placing a 25% Tariff on ‘Electricity’ coming into the United States, I have instructed my Secretary of Commerce to add an ADDITIONAL 25% Tariff, to 50%, on all STEEL and ALUMINUM COMING INTO THE UNITED STATES FROM CANADA, ONE OF THE HIGHEST TARIFFING NATIONS ANYWHERE IN THE WORLD.”

Trump also issued a demand for Canada to lower its tariffs on American agricultural products or face further consequences.

“This will go into effect TOMORROW MORNING, March 12th,” he continued. “Also, Canada must immediately drop their Anti-American Farmer Tariff of 250% to 390% on various U.S. dairy products, which has long been considered outrageous.”

Additionally, Trump announced that he would soon declare a National Emergency on Electricity in affected regions, allowing the U.S. government to take swift action against what he described as “this abusive threat from Canada.”
