The escalating U.S.-Canada trade war threatens to unravel one of the world’s most important economic relationships. Experts warn that higher consumer prices could be just the beginning of the fallout.
After trade talks collapsed last weekend, President Donald Trump imposed 50% tariffs on roughly $20 billion of certain Canadian imports. Those tariffs went into effect Saturday.
On Tuesday, Canada announced that it will retaliate dollar for dollar and rate for rate, imposing tariffs of up to 50% on hundreds of U.S. products, including steel, aluminum, dairy, agricultural equipment, paper and electronics, beginning Sept. 8.
Trump threatened another escalation on Jan. 1, saying he would raise tariffs on cars, trucks, auto parts and steel produced in Canada to 50%.
The latest measures cover a relatively small slice of a vast trading relationship that totaled about $872.3 billion in goods and services last year, according to the U.S. Trade Representative. Canada is the second-largest trading partner to the U.S., behind Mexico.

But economists warn that focusing only on the specific products facing tariffs misses the larger risks.
“There is widespread agreement among economists that broad-based tariffs lead to higher inflation and weaker growth,” said Mark Zandi, chief economist at Moody’s Analytics, “particularly if they spark a trade war with tit-for-tat tariff increases.”
The magnitude of the “economic hit,” Zandi told Straight Arrow, “will depend on how wide-ranging the tariffs are and how long they remain in place.”
Short-term price tag
The direct effect of the latest U.S.-Canada tariffs on overall U.S. inflation could be modest.
Gary Clyde Hufbauer, a senior fellow at the Peterson Institute for International Economics and a longtime trade economist, estimated that the latest tariffs would raise the personal consumption expenditures price index, a key U.S. inflation measure, by less than 0.1%.
Still, Hufbauer told Straight Arrow that American consumers could soon pay more for cars, certain alcoholic beverages, cheese and ice cream.
Olu Sonola, head of U.S. economics at Fitch Ratings, offered a similar assessment.
The latest tariffs “are unlikely to materially alter the trajectory of U.S. inflation,” Sonola told Straight Arrow, but they “will likely raise prices meaningfully for consumers purchasing the affected goods.”
Sonola said the 50% tariff on Canadian cars, trucks and auto parts that Trump says will take effect on Jan. 1 would be far more consequential.
“Given the complexity and deep integration of the North American auto supply chain,” he said, “it will likely raise vehicle prices, disrupt production, and reduce the availability of affected brands and models.”
He noted there is still “considerable time for negotiation” before January.
In fact, these and other future tariffs may never take effect.
Trump has repeatedly threatened steep tariffs only to delay, scale back or drop them after securing concessions from trading partners. He has described tariffs as a bargaining tool that gives the U.S. “great power to negotiate.”
Supply-chain risks
The bigger economic threat may be less visible: higher input costs for U.S. manufacturers and disruptions to supply chains built across the border over decades.
Richard Stern, vice president of the Plymouth Institute for Free Enterprise at Advancing American Freedom, the conservative think tank founded by former Vice President Mike Pence, said many U.S. imports are not finished consumer goods. They are components, raw materials and equipment American businesses use to make other products.
Stern told Straight Arrow that an “American-made” car consists of thousands of parts made in the U.S. and abroad and that, for example, a $50,000 vehicle might rely on an imported $100 computer chip.
A tariff on that chip can raise the cost of the entire vehicle or disrupt its production.
The U.S. Commerce Department notes that materials and components can cross the U.S.-Canada border multiple times during the manufacturing process before the final product reaches consumers.
“While tariffs might directly cover $20 billion in goods,” Stern said, “those goods could be foundational to trillions of dollars of economic activity.”
‘Underappreciated risk’
Sonola said the “underappreciated risk” of the U.S.-Canada tariff battle “is to the U.S. labor market.”
Canada buys roughly 15% of all exported U.S. goods, he noted, and many American jobs depend directly or indirectly on that trade.
There is no reliable estimate of how many American jobs could be lost if the trade war widens. But the scale of the exposure is substantial: Data from the Commerce Department’s International Trade Administration indicate that U.S. exports to Canada supported about 1.4 million American jobs in 2023.
Stern claimed that if the current tariffs stayed in place and the announced tariffs took effect and became permanent — a “nightmare” scenario he believes is highly unlikely — the U.S. could lose millions of jobs and fall into a recession.
But if these tariffs were short-term, lasting about a week, he said businesses could probably “grin and get through it” without shedding workers.
Trump: Canada ‘ripping off’ the US
Asked for comment, the White House referred Straight Arrow to Trump’s posts Tuesday on Truth Social.
In one post, he claimed, in part, that “Canada has been ‘Ripping Off’ the U.S.A. for decades.” In another, the president wrote that “Over the last 10 years, the United States lost, on average, 60 Billion Dollars a year with Canada. No more!”
Trump’s characterization, however, conflates a trade deficit — which just means the value of a country’s imports exceeds that of its exports — with an economic loss.
Much of the trade imbalance, economists note, reflects U.S. purchases of Canadian energy, particularly crude oil, that supplies American refineries and helps power the U.S. economy.
Trump also appears to overstate the U.S. trade deficit with Canada. Census Bureau data show the U.S. goods deficit with its northern neighbor averaged roughly $40 billion a year over the past decade, not $60 billion.
In 2025, the U.S. ran a $48.3 billion goods deficit with Canada but a $27.7 billion surplus in services, according to Trump’s own U.S. Trade Representative. That services surplus is not reflected in the goods-only deficit figures Trump has cited.
As the trade conflict with Canada deepens, Trump and members of his administration have strongly criticized Canadian leaders, in particular Prime Minister Mark Carney.
Trump told Fox News on Sunday that the Canadians are “foolish” to engage in a trade war with the U.S. and accused Canada of wanting “the benefits of being a state, without being one.”
Trump has repeatedly spoken of acquiring Canada, rhetoric that has galvanized Canadian opposition to U.S. trade policies.
Loss of trust
The U.S.-Canada trade battle is putting generations of hard-earned trust on the line.
“It’s hard for me to accept that Trump is turning our closest ally, both economically and militarily, into an adversary,” said Hufbauer. “This makes no sense.”
Stern claimed that Trump’s tariff policies, and the uncertainty around them, have already driven investment out of the U.S. The U.S. is getting “boxed out“ of global trade, he said, and “that trickles out over the entire economy.”
Zandi added that “what is so striking is that the U.S.-Canada trade relationship was among the freest in the world, benefiting both countries.”
Now, he said, “it is among the most vexed, to everyone’s detriment.”
