Senior Canadian official says tariffs will take effect on Tuesday

President Donald Trump launched a trade war against Canada on Saturday by imposing a 25 per cent tariff on virtually all goods from this country — an unprecedented strike against a longstanding ally that has the potential to throw the economy into a tailspin.

Trump’s long-threatened plan to inflict economic pain on Canada has materialized on the day he said it would, and it includes a 10 per cent tariff on Canadian energy products, according to a senior Canadian official who shared details of Trump’s plan with CBC News.

These potentially devastating tariffs will take effect on Tuesday and remain in place until Trump is satisfied Canada is doing enough to stop the flow of fentanyl into the U.S., the government official said.
