Ontario's premier, the leader of Canada’s most populous province, announced that effective Monday it is charging 25% more for electricity to 1.5 million Americans in response to U.S. President Donald Trump's trade war.

Polls show Carney is the preferred leader to negotiate with Trump, who has repeatedly threatened to annex Canada and make it the 51st state and to impose devastating tariffs.

Ontario’s premier said the tariff would remain in place despite the one-month reprieve from President Trump, noting a one-month pause means nothing but more uncertainty.

Ontario is imposing a 25 per cent surcharge on all U.S.-bound electricity, as part of its retaliatory measures against U.S. President Donald Trump’s tariffs on Canadian goods.
