President Donald Trump’s latest escalation with Canada is running into substantial resistance at home. A Reuters/Ipsos poll released September 1 found that only 20% of Americans support higher tariffs on Canadian goods, while 57% oppose them and 21% are unsure where they stand.
The numbers arrive at an unusually sensitive moment. New 50% U.S. tariffs have taken effect on billions of dollars of Canadian imports after trade negotiations collapsed, Canada is preparing its own counter-tariffs, and additional duties threaten the deeply integrated North American auto industry. With Americans already focused heavily on living costs, the findings suggest the administration’s argument for tougher economic pressure on Canada has yet to win broad public support.
The Opposition Is Nearly Three Times the Support
The headline numbers leave relatively little ambiguity about the national mood. Only one in five respondents supported raising tariffs on Canadian goods, compared with 57% who opposed the move. Another 21% could not say where they stood. In other words, opposition exceeded support by 37 percentage points and was nearly three times as common. About one in five respondents also had not heard about the latest tariff development, showing that attitudes are being measured while the dispute is still evolving.
The Reuters/Ipsos poll was conducted online nationwide over three days and concluded on August 30. It included 1,023 U.S. adults and carried a margin of error of four percentage points. That margin means the exact percentages should not be treated as perfectly precise, but the distance between support and opposition is considerably larger than the stated uncertainty. The result therefore points to a substantial public-opinion problem for an administration trying to portray additional tariffs as necessary economic protection.
Trump’s Latest Tariffs Are Steep but Targeted
The administration’s latest move is not a blanket 50% duty on everything Canada sells to the United States. The new Section 338 tariffs apply to selected Canadian products and took effect August 22 after a brief three-day postponement. Washington says the measures are intended to respond to what it considers discriminatory Canadian treatment of American alcohol, dairy products and motor vehicles. Covered products range from wine and dairy-related goods to furniture, cement, clothing, fishing equipment and hockey-related products.
The 50% rate is nevertheless striking. Reuters reported that the latest round covers roughly US$20 billion of Canadian imports, equivalent to about C$27.6 billion according to Canadian government calculations. That represents only a little over 5% of Canada’s exports to the United States, meaning the immediate economic damage is concentrated rather than universal. The White House argues the duties can create opportunities for American producers while pushing Canada to change policies Washington considers unfair. Canada strongly disputes that characterization and suspended negotiations rather than accept the latest U.S. terms.
Canada Is Too Large a Trading Partner for the Fight to Feel Remote
Even a targeted tariff battle with Canada takes place inside one of the world’s largest bilateral commercial relationships. U.S. Trade Representative data show that total U.S. trade in goods and services with Canada was estimated at approximately US$872.3 billion in 2025. Goods alone accounted for roughly US$715.5 billion, including US$333.6 billion of American exports to Canada and US$381.9 billion of Canadian goods entering the United States.
Those figures help explain why trade friction with Canada can look different to American households and businesses than a dispute with a comparatively small trading partner. Canada was the second-largest U.S. goods export market in 2025, meaning Canadian buyers are also customers for American factories, farms and other businesses. During the first half of 2026 alone, U.S. Census Bureau figures show more than US$175 billion in American goods were exported to Canada. Tariffs may protect individual producers from foreign competition, but retaliation and disrupted supply chains can expose other American industries to new costs at the same time.
The Cost-of-Living Backdrop Makes Tariffs Harder to Sell
The public reaction is arriving when household finances are already politically sensitive. The latest available U.S. Consumer Price Index showed prices were 3.4% higher in July 2026 than one year earlier. The Federal Reserve’s preferred personal consumption expenditures price measure was up 3.7% over the same period. Those readings do not prove that the latest Canadian tariffs caused current inflation; the newest duties had not even been in effect long enough to do so.
They do, however, demonstrate the environment in which Americans are judging the policy. A separate Reuters/Ipsos poll released August 31 found that 71% of Americans disapproved of Trump’s handling of the cost of living, including four in ten Republicans. Reuters reported that living costs were the leading issue shaping how voters said they would approach the November midterms. When households are already paying close attention to grocery bills, transportation and other recurring expenses, policies that could raise some imported-goods prices face a more difficult political test than they might during a period of low inflation.
Economic Research Shows Why Consumers Worry About Tariffs
Tariffs are legally collected from importers, and decades of political debate have revolved around how much of that cost ultimately reaches consumers. Research from the 2018-2019 U.S. trade war found that American tariffs were passed almost completely into prices paid by U.S. importers. A major National Bureau of Economic Research study by Mary Amiti, Stephen Redding and David Weinstein estimated that the earlier tariff episode reduced U.S. real income by about US$1.4 billion per month by the end of 2018.
More recent research examining the 2025 U.S. tariff increases provides additional context. A July 2026 NBER paper estimated that about 26% of a tariff increase passed through to consumer prices, with effects extending beyond imported products. Researchers found that higher input costs could raise prices for domestically produced goods as well, while reduced foreign competition gave some U.S. producers more room to increase markups. Those findings do not predict the precise effect of the new Canada duties, but they help explain why voters may associate higher tariffs with higher household costs.
Canada’s Retaliation Creates a Second Risk for U.S. Businesses
The economic effect does not stop at the U.S. border. Ottawa has announced that it will match the latest American measures dollar for dollar and, where applicable, rate for rate. Beginning September 8, Canada plans additional tariffs of 15%, 25% and 50% covering C$27.6 billion worth of U.S. imports. The official Canadian list includes products connected to steel, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics.
That matters because retaliatory tariffs shift part of the trade dispute onto American exporters rather than American importers. Canadian Industry Minister Mélanie Joly said Ottawa selected some products with an eye toward putting political pressure on specific U.S. states ahead of the November elections. Canada has simultaneously announced C$7.5 billion in new and enhanced support for affected workers and businesses. This is a familiar pattern in trade conflicts: one government tries to shield favored domestic industries, the other answers with targeted retaliation, and companies that had little role in the original disagreement suddenly find themselves paying for it.
The Auto Industry Could Turn a Limited Fight Into a Much Bigger One
The most consequential escalation may still be ahead. Trump has announced 50% tariffs on Canadian cars, trucks and automotive parts beginning January 1, 2027 if the dispute is not resolved. Automotive trade is particularly sensitive because production is distributed across the continent. Vehicles and components routinely move through supply chains involving plants and suppliers on both sides of the border rather than being manufactured entirely inside one country.
Canadian officials have made clear that preserving the country’s auto assembly and parts sector is a central condition for any eventual agreement. Canada’s ambassador to Washington, Mark Wiseman, told Reuters that maintaining those capabilities and jobs was critical, particularly in Ontario and Quebec. The current 50% tariff package is relatively narrow, but bringing broader automotive products under a rate that high would substantially increase the economic stakes. That looming possibility may also help explain why public attitudes toward escalation matter now: Americans are being asked about tariffs while the dispute still has room to become considerably more disruptive.
The Poll Lands at a Difficult Moment for Trump and Republicans
Public resistance to the Canada tariffs would be less politically important if the administration were entering the midterms from a position of overwhelming strength. Instead, a separate Reuters/Ipsos poll concluded August 31 with Trump’s approval rating at 33%, which Reuters described as the lowest level of his political career and the third consecutive reading at that level. Republicans are preparing to defend narrow congressional majorities in the November 3 elections.
Other numbers from the same polling add to the pressure. Forty-six percent of self-identified Democrats said they were very enthusiastic about voting, compared with 31% of Republicans. Among independents, 36% said they would vote Democratic if congressional elections were held immediately, while 22% selected Republicans. None of that establishes that Canada tariffs will determine control of Congress. Midterm elections turn on numerous issues. But an unpopular trade escalation adds another potential vulnerability when dissatisfaction with economic management and household costs is already prominent.
The Lake Ontario Fight Suggests the Discomfort Goes Beyond Economics
The same Reuters/Ipsos polling found even stronger opposition to one of the dispute’s symbolic elements. Trump signed an order on August 27 directing U.S. federal agencies to refer to Lake Ontario as “Lake America.” Only 14% of Americans supported the change, while 63% opposed it. The order governs U.S. federal terminology; it does not dictate the terminology used by Canada, international organizations or other institutions.
That finding matters because the Canada confrontation has increasingly blended economic policy with rhetoric about national identity and sovereignty. Trump has previously spoken about Canada potentially becoming a 51st state and began his second term by directing the U.S. government to use “Gulf of America” for the Gulf of Mexico. The Lake Ontario episode produced immediate resistance in Canada and among some American political leaders. Viewed alongside the tariff numbers, the polling indicates that the public’s hesitation is not confined to technical disagreements over duty rates. The more confrontational tone of the relationship itself appears to have limited appeal.
The Numbers Increase Pressure for a Deal, but They Do Not Guarantee One
The Reuters/Ipsos findings should not be read as proof that Americans oppose every tariff or every effort to confront Canadian trade practices. The question dealt specifically with higher tariffs on Canadian goods amid the current dispute. Earlier polling has shown that Americans can be more receptive to tariffs when they are presented as protecting strategic industries or strengthening domestic production. Public opinion can also shift as economic conditions, negotiations and political messaging change.
For now, however, the numbers give both governments another factor to consider. Trump can point to his administration’s stated objective of protecting American producers and challenging Canadian policies it considers discriminatory. Ottawa can point to the scale of opposition inside the United States as evidence that escalation carries American political costs as well. The immediate question is whether that pressure helps restart negotiations before Canadian counter-tariffs take effect September 8 or before the threatened January auto duties arrive. With just 20% backing higher Canada tariffs today, widening the fight would mean asking Americans to support a policy they currently reject by a substantial margin.
