Canadian Prime Minister Justin Trudeau on Tuesday highlighted the adverse effects of the U.S. steel and aluminum tariffs and warned of a strong response if required. What Happened: Trudeau criticized the recent tariffs calling them “Unacceptable” and said “Canadians will stand up strongly and firmly if we need to,

Canadian Prime Minister Justin Trudeau said on Tuesday that Canada would seek to highlight the negative impact of the United States' steel and aluminium tariffs and that - if needed - the response from Canada would be firm and clear.

Trudeau, who is in Paris for a global AI (artificial intelligence) conference, was reacting to the news Monday that US President Donald Trump had instituted tariffs on all imports of the two products, including those from Canada. The tariffs take effect March 4.

Trump says he will levy a 25% import tax on all steel and aluminium products entering the US from 12 March, meaning both sides have a month to negotiate. Canada is the top exporter of both metals to the US.

Canadian Prime Minister Justin Trudeau said Canada and the U.S. should be working together but that the country will stand up for itself if needbe.

As U.S. President Donald Trump threatens to hit Canada with steep tariffs, several former prime ministers are calling on Canadians to express their national pride and "show the flag."
