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

Ontario Premier Doug Ford responds to President Donald Trump's higher steel and aluminum tariffs that went into effect Wednesday, doubling from 25% to 50%.

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,

The increase in U.S. metals tariffs applies to all trading partners except Britain, the only country so far to strike a preliminary trade agreement with America during a 90-day pause on a wider array of Trump tariffs.

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.

Another is that tariffs on “intermediate” goods, such as raw materials used to make other things, affect consumer prices indirectly. Even service industries depend on imported goods—think of lawyers using smartphones or computers made abroad.

President Donald Trump is hiking tariffs on aluminum and steel as his administration presses countries to speed up trade talks, amid legal battles.

The Congressional Budget Office projected President Trump's tariffs could raise trillions of dollars over the next decade — but they could also lead to higher inflation and slower economic growth.
