Canada announced $ 21 billion in new rates on Wednesday at the import of American computers and sports equipment.
It is the last escalation of the increasingly bitter and expensive trade war that Washington and Ottawa flood.
The last step comes hours after the 25 percent rates of President Donald Trump on Canadian Staal and Aluminum were put into operation.
Canada is the largest foreign supplier of both metals to the US
Dominic Leblanc, the Canadian Finance Minister, said on Wednesday that the list of products that are affected by the new rates includes computers, sports equipment and cast iron products.
Leblanc said: “Today I announce that the Government of Canada, after a dollar-for-dollar approach, will impose, from 12:01 pm tomorrow, March 13, 2025, 25 percent mutual rates for an extra C $ 29.8 billion ($ 20.7 billion) of imports from the United States.”
He added: “This includes steel products worth C $ 12.6 billion and aluminum products worth C $ 3 billion and extra imported American goods worth C $ 14.2 billion.”

The trade war between the US and Canada will take place after the northern neighbors have announced a new wave of mutual rates after the 25 percent fine on the steel of Canada and aluminum came into effect
Canada folded to Trump on Tuesday after he promised that the nation would pay a historically large 'financial price' for the electricity rate that imposed the US parts
Ontario Prime Minister Doug Ford returned the course and said that he would cancel the 25 percent rate on Canadian electricity that was delivered to the northern states of Michigan, New York and Minnesota.
Trump agreed, after Canada had withdrawn, not to double the rates on Canadian steel and aluminum to 50 percent, which means that they stay at 25 percent.
The electricity rates of Canada that were implemented on Monday were an escalation in the trade war and came in response to previous rates from Trump.
The Prime Minister said he spoke with Commerce Secretary Howard Lutnick about the situation and they agreed on Thursday to discuss mutual rates that Trump wants to set up on 2 April.
“Ontario agreed to suspend his 25 percent surcharge in the export of electricity to Michigan, New York and Minnesota,” said Ford.
In the midst of the intensifying trade war, the president repeated his call to the US to bring Canada into the fold.
“Canada must be honestly our 51st state. We would not have a northern border problem. We would not have a tariff problem, “said Trump.
“Canada would be great if our cherished 51st state. You would not have border problems. You would have nothing. '
Earlier Tuesday, Trump explained a national emergency situation in the United States and doubled the rates on aluminum and steel from Canada after Ford had introduced his electricity rate.
