The measures will affect around $12.6bn of US-made steel and $3bn of aluminium, as well as $14.2bn of other American goods such as computers, cast-iron products and sports equipment.
The duties, which cover $29.8bn of products, will come into effect from Thursday and follow a "dollar-for-dollar approach" in retaliation to Trump's launch of 25% additional tariffs on imported steel and aluminium.
According to the country's finance minister Dominic LeBlanc, the government was "do[ing] what we must to protect Canada's economy".
"The US administration is once again inserting disruption and disorder into an incredibly successful trading partnership and raising the costs of everyday goods for Canadian and American households alike," he said.
Meanwhile, foreign minister Mélanie Joly attacked Trump's recent comments about making Canada the "51st state", saying: “The only constant in this unjustified and unjustifiable trade war seems to be President Trump’s talks of annexing our country’s through economic coercion."
In a statement to the American public, Joly said: "Canada is not the one driving up the cost of your groceries or of your gasoline or any of your construction. Canada is not the one putting your jobs at risk. Canada is not the one that is ultimately starting this war. President Trump’s tariffs against you are causing that and there are no winners in a trade war."
