How Canada could hit back to hurt the US economy amid the Canada-US trade war and 2026 tariffs
The relationship between Washington and Ottawa has entered its rockiest stretch in decades, and the latest escalation has made clear that Canada is no longer content to simply absorb blow after blow. After talks between American and Canadian negotiators collapsed in Washington last week, the United States pushed ahead with a 50 percent tariff on roughly 20 billion dollars worth of Canadian goods, hitting everything from wine and furniture to cement, clothing, fishing rods and hockey equipment. Prime Minister Mark Carney did not wait long to respond. He announced that Canada would match the move dollar for dollar, with new tariffs on American steel, dairy, appliances, farm equipment, pulp and paper, and electronics set to take effect on September 8.
“You’re at war when you get attacked. We got attacked,” Carney told reporters in Ottawa, a blunt characterization of a trade relationship that has been fraying since February 2025, when the first wave of sweeping American tariffs on Canadian imports triggered retaliatory duties that grew from an initial 30 billion dollars to 155 billion dollars within weeks. What is different this time is the tone. Carney, a former central banker not known for theatrics, called the new American levies “a miscalculation,” and President Donald Trump fired back on social media that Canada “wants the benefits of being a State, without being one.” The rhetoric has hardened, but so has the underlying economic calculus on both sides.
Tariffs alone, though, are only part of the story. The more consequential question circulating in Ottawa, in provincial capitals, and among economists who study North American trade is what happens if Canada decides to stop playing defense and start using the resources America genuinely cannot do without. That conversation has moved from the margins to the center of Canadian politics in recent weeks, and it centers on a handful of commodities where Canada holds outsized global leverage: uranium, potash, crude oil, natural gas, electricity, and critical minerals.
Consider the numbers. Canada supplies roughly 63 percent of all crude oil imported into the United States and close to 99 percent of its natural gas imports, according to figures widely cited by trade analysts tracking the dispute. It also produces close to a quarter of the world’s uranium supply, much of which travels from mines in Saskatchewan to refineries in Ontario before being enriched at American facilities that power dozens of nuclear reactors. Ontario Premier Doug Ford has been the most vocal advocate for using that dependency as a bargaining chip, warning that the province could cut off electricity and critical mineral shipments entirely if the trade fight worsens. “I’ll cut them off,” Ford said of critical minerals exports. “You won’t get a grain of sand out of Ontario.”
Potash occupies a similarly strategic position. Canada is the world’s largest producer of the fertilizer input, and American farmers depend heavily on it to keep crop yields where they need to be. Cutting or taxing that flow would not just squeeze industrial buyers, it would ripple directly into food prices and the agricultural sector that forms a core part of Trump’s political base, which is likely why some Canadian officials and former leaders see it as one of the sharpest tools available. Former Prime Minister Jean Chrétien has revived a proposal he first floated in 2025, arguing that Canada should impose an export levy on potash, oil, gas, aluminum and electricity specifically because Washington chose to exempt those goods from its own tariffs. His logic is straightforward: if the United States needs something badly enough to leave it off its own tariff list, that is precisely the leverage Canada should be applying pressure through, not protecting. Conservative leader Pierre Poilievre has made a related argument, calling for Canada to build a strategic reserve of oil and critical minerals reserved for trading partners willing to offer tariff-free access, a pointed signal to Washington that resource access is not unconditional.
Not everyone in Canada agrees this is the right path. Saskatchewan Premier Scott Moe, whose province produces the bulk of the country’s uranium and potash, has pushed back publicly, warning that turning resources into a weapon would be “counter-productive” and could damage the long-term commercial relationships that took decades to build. That tension between provinces that produce the resources and federal or opposition voices eager to use them as leverage reflects a genuine split in how Canada should proceed, and it is not yet resolved.
There is also a technology dimension that makes this dispute matter well beyond steel mills and dairy farms. Critical minerals like nickel, cobalt, graphite and rare earth elements are essential to batteries, semiconductors, and the data center buildout powering the artificial intelligence boom. China’s tightening grip on rare earth processing has already rattled manufacturers worldwide, and Washington has spent the past year trying to diversify away from Chinese supply chains. Canada represents one of the few politically aligned alternatives with the geology to make that diversification realistic. Squeezing Canada too hard, some trade analysts warn, risks pushing Ottawa toward deeper resource partnerships with Europe, Japan, or even China at the exact moment the United States is trying to build a non-China supply chain for the technologies that will define the next decade.
That is the paradox sitting underneath the current standoff. The White House has framed its tariffs as a tool to correct trade imbalances and protect American manufacturing, and the Office of the United States Trade Representative continues to defend the broader tariff strategy as necessary leverage in ongoing negotiations. But the commodities where Canada holds the most genuine power, energy, uranium, potash and critical minerals, are largely the ones Washington has been careful not to tax, precisely because American industry cannot easily replace them. That selective restraint is itself a tell. It suggests policymakers in Washington understand what Ottawa is only now beginning to seriously consider: that Canada’s real bargaining chip was never the dollar-for-dollar tariff match on hockey sticks and cement, but the resources sitting underground and in its power grid.
Whether Carney’s government actually pulls that lever remains uncertain. Doing so would mark a significant escalation beyond tit-for-tat tariffs and could invite retaliation that hits Canadian workers just as hard as American consumers. But the fact that former prime ministers, sitting premiers, and opposition leaders are now openly debating export levies on energy and critical minerals shows how far this dispute has traveled in a matter of months. What began as a fight over tariff schedules has turned into a broader argument about who actually holds the upper hand in the most economically intertwined relationship on the planet, and Canada appears increasingly willing to test that question directly.
