TORONTO — Canadian officials on Tuesday blasted President-elect Donald’s Trump’s threat to impose sweeping tariffs, as the leader of the country’s most populous province called Trump’s comparison of Canada to Mexico “the most insulting thing I’ve ever heard.”

President-elect Donald Trump has already begun to captivate financial markets with his unorthodox negotiating style, as evidenced by the reaction to his Tuesday night threat to impose 25% tariffs on Mexico and Canada and a surcharge tariff of 10% on China.
