It was barely a year ago when the first headlines hit, and honestly, the shock still hasn't quite worn off for business owners from Windsor to Winnipeg. You’ve probably seen the news clips: "Trade War 2.0," "The End of CUSMA," or "Border Chaos." But if you actually dig into the numbers, the reality of USA tariffs on Canada is way more tangled than a simple "us vs. them" narrative.
Last March, the world tilted. The Trump administration dropped a hammer in the form of a 25% baseline tariff on basically everything crossing the border. Energy got a bit of a "break" at 10%. Since then, it’s been a rollercoaster of exemptions, retaliations, and legal bickering that has left supply chains looking like a bowl of tangled spaghetti.
We aren't just talking about abstract policy here. We’re talking about your neighbor’s construction company paying 50% more for steel beams. We're talking about the price of a Ford F-150 jumping because a specific aluminum part crossed the Detroit-Windsor bridge four times before the truck was even finished.
The 50% Club: Steel and Aluminum
If you want to understand the real sting of USA tariffs on Canada, you have to look at the metals. This isn't just a tax; it’s a total reshaping of the North American industrial heartland.
Starting in mid-2025, the U.S. cranked the Section 232 tariffs on Canadian steel and aluminum up to a staggering 50%. Yeah, you read that right. Half the value. While most "CUSMA-compliant" goods eventually found a way to stay tariff-free—roughly 85% of total trade—steel and aluminum were pointedly left out in the cold.
Why? Washington claims it's a national security issue. Ottawa calls it a violation of the free trade agreement. The result is that Canadian-origin carbon steel imports into the U.S. dropped by 32% last year. It’s a mess.
But here’s the kicker: the U.S. still needs that steel. Domestic mills can’t produce everything the construction and auto sectors require. So, American builders are often just paying the 50% markup and passing that cost straight to you, the consumer.
Softwood Lumber: The Forever War
If steel is the new headache, softwood lumber is the old, chronic back pain that just won’t go away.
- October 2024: U.S. hits Canadian lumber with a 35% total tariff.
- January 2026: New rules keep a 25% tariff on upholstered furniture and kitchen cabinets steady, rather than the feared jump to 30%.
- The "Vanity" Tax: If you're remodeling a bathroom this year, that Canadian-made vanity is likely 25% more expensive because of these specific trade actions.
It feels personal. Especially for the 100,000+ Canadians whose livelihoods depend on the forestry sector.
Prime Minister Carney’s Pivot to the East
While Washington was tightening the screws, Ottawa didn't just sit on its hands. Prime Minister Mark Carney—who stepped in with a "fixer" reputation—has been playing a very different game.
Just this week, in mid-January 2026, Carney was in Beijing. He basically said, "If the U.S. is going to be unpredictable, we’re going elsewhere."

It’s a massive gamble. Canada just slashed tariffs on Chinese electric vehicles (EVs) from 100% down to 6.1% for a specific quota of cars. In exchange, China is dropping its tariffs on Canadian canola to around 15% by March.
You can imagine how this is going over in Washington.
The U.S. trade office isn't thrilled about Chinese EVs "backdooring" into North America through Canada. This "policy divergence," as the suits call it, is putting the upcoming July 2026 CUSMA review on a collision course. Honestly, it feels like we’re watching a slow-motion car crash between three different trade strategies.
What This Means for Your Wallet
Let’s be real: tariffs are just a sales tax with a fancier name.
When the U.S. imposes USA tariffs on Canada, the Canadian exporter doesn't usually just "pay" it. They raise their prices. Or they stop selling to the U.S. entirely.
- Groceries: Canada retaliated last year with 25% tariffs on things like orange juice, peanut butter, and wine. While most of those were lifted in September 2025 to "de-escalate," the underlying instability keeps prices high.
- Cars: If your vehicle wasn't built in North America with a high percentage of local parts, it’s facing a 25% tariff.
- Housing: Between 50% steel tariffs and 35% lumber tariffs, the cost of building a new home has surged. The Canadian Real Estate Association (CREA) noted a "tariff-induced slowdown" in the market through 2025.
Expert Note: Keep an eye on the U.S. Supreme Court. They are currently reviewing whether the President actually has the power to use the International Emergency Economic Powers Act (IEEPA) to slap these tariffs on allies. If they rule against it, we could see billions in refunds—but don't hold your breath.
Actionable Steps for Businesses and Consumers
Navigation is the name of the game now. You can't just "wait for it to blow over" anymore. This is the new normal.
For Small Business Owners
- Audit Your Supply Chain: You need to know exactly where every component comes from. If your "Canadian" product uses 40% Chinese steel, you might get hit with the "transshipment" penalty of 40% when you try to export it to the U.S.
- Check De Minimis Changes: The U.S. basically killed the $800 "tax-free" threshold for low-value shipments. Every package counts now. Factor in those duties before you ship.
- Diversify, Diversify, Diversify: Follow the government’s lead. Look at the UK or Southeast Asian markets. Relying 100% on U.S. buyers is currently a high-risk strategy.
For Everyday Consumers
- Buy "CUSMA Compliant": Look for goods clearly labeled as made in Canada, the U.S., or Mexico with high regional content. These are the most likely to stay at "normal" prices.
- Delay Major Renovations: If you can wait until after the July 2026 trade review, do it. There’s a slim chance the 50% steel and 35% lumber tariffs get negotiated down as part of the broader deal.
- Watch the Loonie: Trade wars usually beat up the Canadian Dollar. If you’re planning a trip south or buying U.S. tech, keep an eye on the exchange rate, which is being dragged down by the tariff uncertainty.
The trade relationship between the U.S. and Canada used to be the most boring, stable thing in the world. Those days are gone. Whether it’s fentanyl politics, border security, or just old-fashioned protectionism, USA tariffs on Canada are the lever being used to move the world.
Prepare for a bumpy ride through the 2026 CUSMA review. The "special relationship" is currently in the middle of a very expensive therapy session.
Next Steps to Protect Your Interests:
- Review your import/export HTS codes to ensure you aren't being overcharged under the new June 4th metal surcharges.
- Consult a trade lawyer if you are importing "derivative" steel products, as the "stacking" rules (where you might pay two different tariffs on one item) are notoriously easy to mess up.
- Monitor the February 6, 2026 transition to electronic refunds by U.S. Customs (CBP) if you have pending tariff drawback claims.
