US President Donald Trump on Tuesday escalated the trade war with Canada by doubling the tariff on steel and aluminum imports from that country. Trump announced the additional 25 per cent tariff on Canadian steel — taking it up to 50 per cent — in a long post on his social media platform Truth Social. The new tariff rates go into effect from Wednesday. Trump said further: \”Also, Canada must immediately drop their Anti-American Farmer Tariff of 250 per cent to 390 per cent on various US dairy products, which has long been considered outrageous. I will shortly be declaring a National Emergency on Electricity within the threatened area\” Trump also slammed Canada on its defence spending. \”Canada pays very little for National Security, relying on the United States for military protection. We are subsidizing Canada to the tune of more than 200 Billion Dollars a year. Why??? This cannot continue,\” he said. He doubled down on his threats to turn Canada into the 51st state of the US. \”The only thing that makes sense is for Canada to become our cherished Fifty First State. This would make all tariffs, and everything else, totally disappear,\” he added.
