Canada's most populous province has imposed a twenty-five percent surcharge on electricity exports to the United States in response to tariffs imposed by Washington. The premier of Ontario, Doug Ford, said he would be prepared to cut off power supplies altogether unless the US changed course. He said the surcharge would raise a total of up to four hundred thousand dollars a day from the states of New York, Michigan and Minnesota. On Sunday, Canada's next Prime Minister, Mark Carney, said the national government was right to retaliate against US tariffs. He said Canada would maintain its own duties on US goods until the Americans showed some respect. We hear from Yasir Naqvi, from Mr Carney's Liberal Party.
