Updates with comments from US utilities
Ontario is imposing a 25pc tariff on electricity exports to the US starting today, carrying through on its threatened retaliation for a trade war started by US president Donald Trump.
"We will apply maximum pressure to maximize our leverage, that's why today we're moving forward with a 25pc surcharge on electricity exports for the 1.5mn American homes and business that Ontario powers," Ontario premier Doug Ford said today in Toronto.
Ontario was the largest exporter of electricity to the US in 2023, sending 15.2 TWh to New York, Michigan and Minnesota. The neighbouring province of Quebec, which exported 13.4 TWh the same year to New York and New England, has said it is also considering its options amid the trade war.
Ford said he feels "terrible" because average consumers will pay when it is really Trump who is responsible. The surcharge will cost the US up to $400,000/d, amounting to an increase of $100 for consumers each month, according to Ford.
"I will not hesitate to increase this charge," said Ford. "If necessary, if the United States escalates, I will not hesitate to shut the electricity off completely."
Trump on 4 March imposed a 10pc tax on Canadian energy imports, a 25pc tariff on non-energy imports from Canada and a 25pc tariff on all imports from Mexico. But executive orders that he signed on 6 March exempted North American trade covered by the US-Mexico-Canada (USMCA) free trade agreement from new tariffs after 12:01am eastern time on 7 March.
Trump has said he is delaying the tariffs on Canada and Mexico until 2 April, but his executive orders make no mention of that restart date.
Minnesota Power, a subsidiary of Allete, imports "a small portion" of its electricity from Ontario but expects the impact to be "negligible", the utility said. Minnesota Power receives 11pc of its of its energy supply from Manitoba Hydro, but Manitoba has not followed Ontario's lead and imposed a surcharge.
Michigan's largest utility, Consumers Energy — which serves 6.8mn of the state's 10mn residents — does not purchase power from Ontario.
Xcel Energy, which serves customers in Minnesota and Michigan, also said it did not buy power from Ontario.
