Unifor, Canada's private sector union, and the Aluminium Association of Canada have expressed serious concerns over the immediate impact of the tariffs.

Canada is going to wait before enacting any further retaliation against the U.S. over higher steel and aluminum tariffs because negotiators are in talks on a new bilateral economic-and-security deal,

Canada’s PM Mark Carney called Donald Trump’s new tariffs “illegal” and “unjustified,” but said he wants to see how ongoing trade negotiations with the U.S. play out.

Canadian Prime Minister Mark Carney and U.S. President Donald Trump are in direct communication as part of Ottawa's bid to persuade Washington to lift tariffs, Industry Minister Melanie Joly said on Thursday.

Prime Minister Mark Carney said Canada won’t respond immediately to the Trump administration’s doubling of steel and aluminum tariffs, and indicated that officials are in “intensive discussions” about the trade relationship between the countries.
