Although President Donald Trump has delayed most—but not all—of the tariffs imposed on Canada and Mexico, America’s northern neighbor is not holding back in its response.

Ontario Premier Doug Ford announced at a press conference that a 25% surcharge on electricity exports to three U.S. states will take effect starting Monday. He also issued a stern warning: if the U.S. imposes additional tariffs on Canadian goods, he would consider cutting off electricity access entirely.

“If the United States escalates, I won’t hesitate to shut off electricity completely,” Ford stated. “I take no pleasure in this, and I sympathize with the American people. They are not to blame for this trade war—one person is, and that’s President Trump.”

Ford emphasized that the 25% surcharge would have a financial impact on households and businesses in New York, Minnesota, and Michigan, increasing electricity bills by approximately $100 per month for many Americans. However, the move could also negatively affect Canada’s energy sector. Given its heavy reliance on U.S. exports, Canada risks falling into a recession if tensions escalate. As the saying goes, no one truly wins in a trade war.

In addition to his threat of an electricity cutoff, Ford hinted at the possibility of increasing the surcharge if U.S. tariffs continue to rise. Trump has already signaled such an escalation, warning on Friday that he might impose tariffs on Canadian dairy and lumber products, mirroring Canada’s duties on U.S. goods. On Sunday, Trump also suggested that tariffs on Canada and Mexico could exceed 25% if those nations fail to take stronger measures to curb fentanyl trafficking into the U.S.

Last week, Ford asserted that he would disconnect power to the U.S. “with a smile” if Trump persisted in imposing tariffs on Canadian exports.

A well-known political figure in Ontario, Ford has recently made multiple appearances on U.S. cable news, highlighting his firm stance against Trump’s trade policies.
