Asked upon his arrival for the second and final day of the Artificial Intelligence (AI) Action Summit in Paris about the issue of tariffs on Canadian steel and aluminium, Canadian Prime Minister Justin Trudeau stated that such tariffs would be "entirely unjustified" and that "Canadians will resist strongly and firmly if necessary," after US President Donald Trump signed an executive order setting March 12 as the date for the implementation of new 25% tariffs on "all imports of aluminium articles and derivative aluminium articles from Argentina, Australia, Canada, Mexico, EU countries, and the UK."
