How did Canada’s response become dollar-for-dollar retaliation?
Canada first answered the IEEPA order with a C$155 billion retaliation plan and began its first C$30 billion tranche when the U.S. tariffs took effect. It matched later Section 232 metal duties and imposed vehicle counter-tariffs, but also showed restraint by dropping counter-tariffs on USMCA goods while retaining those on steel, aluminum and autos. After Section 338 duties began on roughly $20 billion of Canadian exports, Ottawa published a C$27.6 billion schedule explicitly set rate for rate against the United States and put it into force. The practical lesson is to track the product list and tariff authority: Canada’s response was targeted and changed with the U.S. measure, rather than remaining a single blanket counter-tariff.

President-elect Trump vows a 25 percent tariff on everything from Canada and Mexico
Three weeks after the election, Trump posted on Truth Social that one of his first-day executive orders would put a 25 percent tariff on all products from Canada and Mexico, to stay in place until the two countries stopped drugs, especially fentanyl, and migrants crossing into the United States. It was the opening move of a trade war with a partner that had a free-trade agreement Trump himself had signed in 2018.

President Trump promised in November to “sign all necessary documents to charge Mexico and Canada a 25% Tariff on ALL products coming into the United States, and its ridiculous Open Borders.”
Why it matters here. The threatened 25 percent tariff led to the IEEPA order in which Canada announced its C$155 billion response.

The tariffs take effect; Canada's first C$30 billion of counter-tariffs start the next morning
When the pause ran out, the 25 percent tariff and the 10 percent energy tariff took effect on March 4. Trudeau said less than 1 percent of fentanyl intercepted at the U.S. border came from Canada and that seizures had fallen 97 percent, and put the first C$30 billion tranche of counter-tariffs in place at 12:01 a.m. the next day, with the remaining C$125 billion to follow in 21 days.

Canada's 25 percent counter-tariffs on U.S. vehicles take effect
Six days after the U.S. auto tariffs began, Canada's mirror measure came into force: 25 percent on fully assembled vehicles from the United States that do not meet USMCA rules, and 25 percent on the non-Canadian, non-Mexican content of vehicles that do, with a remission framework for automakers that kept production in Canada. Carney had announced the response on April 3, the day the U.S. tariff started.

50 percent tariffs take effect on about $20 billion of Canadian goods; Carney: 'they asked too much and offered too little'
The Section 338 duties started at midnight on roughly $20 billion of exports including wine, furniture, dairy, cement, clothing and hockey equipment, about 4 percent of what Canada sells to the United States. At a press conference Carney promised dollar-for-dollar retaliation from September 8, concentrated in steel, dairy, appliances, farm equipment, pulp and paper and electronics, and when asked why it felt like going to war, said 'because we were attacked'. The Canadian dollar fell on Monday.

Carney drops the counter-tariffs on USMCA goods from September 1, keeping steel, aluminum and autos
After a call with Trump, Carney announced Canada would match the U.S. exemption by removing its tariffs on American goods covered by USMCA, saying the two countries had re-established free trade for the vast majority of goods and that Canada had the best deal of any U.S. partner. The steel, aluminum and auto counter-tariffs stayed. Critics asked whether 'elbows up' had become folding; the White House called the move long overdue.
