Ontario Premier Doug Ford has warned of potential retaliatory measures, including halting energy exports to the U.S., if President-elect Trump imposes a 25% tariff on Canadian goods. Trump proposed the tariff to address illegal immigration and drug trafficking. Ford suggested Ontario could cut off energy supplies to Michigan, New York, and Wisconsin, and mentioned other officials are exploring ways to impact U.S. exports, including restricting critical minerals and metals. While Ontario's oil production is minimal, it's a significant producer of hydro and nuclear power. Canada was the primary source of U.S. energy imports in 2019. Ford also hinted at potentially banning American-made alcohol sales in Ontario. However, a political science professor noted that Ford might need federal approval to halt energy exports. Trump, responding to the threats, stated the U.S. shouldn't subsidize Canada and that he has numerous Canadian friends. Despite the tension, Prime Minister Justin Trudeau met with Trump, which the latter described as "very productive."
