You’ve probably heard a lot of noise lately about "trade wars" and massive border taxes. It feels like every headline is a fresh scream about some new levy. But honestly, if you look back at the relationship before the 2017 era, the story of canadian tariffs on us goods before trump wasn't exactly a blank slate of total free trade. People like to think of the pre-2017 days as this golden age of frictionless borders. It wasn't.
Sure, we had NAFTA. We had the 1989 Free Trade Agreement. But even with those massive deals in place, Canada wasn't just letting every single American product slide through the gates for free. There were walls. Some of them were small, and some were—frankly—huge. If you were an American farmer trying to sell milk or a chicken producer looking at the Ontario market, you weren't looking at "free trade." You were looking at a fortress.
The Fortress of Supply Management
The biggest thing most people get wrong about the history of canadian tariffs on us goods before trump is the idea that tariffs were zero. For most stuff, yeah, they were. But for dairy, poultry, and eggs? Not even close.
Canada has this system called "supply management." Basically, they limit how much their own farmers can produce to keep prices stable. To make that work, they have to stop a flood of cheap American milk from coming in. They do this through Tariff Rate Quotas (TRQs).
Basically, a tiny amount of US dairy could come in duty-free. Once you hit that limit, the hammer dropped. We’re talking tariffs of 200% to 300%. That isn't a typo. If an American dairy company wanted to sell butter past the quota, they were hit with a 298% tax. This wasn't a Trump-era invention; this was a cornerstone of Canadian policy for decades, protected fiercely under both Liberal and Conservative governments.
The Endless Softwood Lumber War
If dairy was the fortress, softwood lumber was the forever war. This dispute has been going on since roughly 1982. It’s the "Lumber III," "Lumber IV," "Lumber V" saga that never seems to end.
The US argued (and still argues) that Canada unfairly subsidizes its timber because the government owns most of the land and charges "stumpage fees" that are way below market value. In response, the US would slap duties on Canadian wood. Canada didn't just sit there. They fought back through the WTO and NAFTA panels.
While these were technically "countervailing duties" and not always standard tariffs, the effect was the same: a tax at the border that messed with the price of a 2x4. Before the 2017 shift, the 2006 Softwood Lumber Agreement actually managed to keep things quiet for about nine years. But once that expired in 2015—right before the political landscape shifted—the "war" started right back up.

Beyond the Big Three: What Else Was Taxed?
Most people think NAFTA wiped out every single duty. It didn't.
For one, there’s the "Most-Favored-Nation" (MFN) rate. Even before the trade flares of the late 2010s, Canada maintained a baseline tariff rate of about 35% for countries they didn't have a deal with. Because of NAFTA, the US usually avoided this. But "usually" doesn't mean "always."
If a product didn't meet the "Rules of Origin"—meaning it wasn't made with enough North American parts—it didn't get the NAFTA discount. You’ve got a pair of sneakers made in a US factory but using mostly overseas materials? Canada could, and would, tax those. In 2017, just as the era was changing, Canada was still collecting roughly $5.7 billion in duties. About 12% of that came specifically from motor vehicles that didn't meet the strict regional content rules.
The Breakdown of Pre-Trump Canadian Duties
- Dairy/Poultry: Massive (200%+ on over-quota goods).
- Softwood Lumber: Periodic duties depending on the current "war" status.
- Non-NAFTA Compliant Goods: Standard MFN rates (often around 5-18%).
- Wine and Spirits: Not always a "tariff" in name, but provincial liquor boards often applied "cost-of-service" markups that functioned exactly like a tax on American Napa Valley imports.
When Canada Actually Used Retaliatory Tariffs
We often think of Canada as the polite neighbor that only reacts, but they’ve used the tariff stick before. In the early 2010s, there was a huge fight over Country of Origin Labeling (COOL) for meat. The US wanted to label where every cow was born and slaughtered. Canada (and Mexico) said this was a hidden trade barrier that made their meat less attractive.

The WTO agreed with Canada. Armed with that legal win, Canada threatened to slap retaliatory tariffs on a massive list of US goods—everything from cherries to office furniture. The threat was so credible that the US Congress actually blinked and repealed the labeling law in late 2015 to avoid the taxes.
It shows that canadian tariffs on us goods before trump weren't just passive leftovers; they were active tools of diplomacy.
What This Means for You Now
If you’re a business owner or just someone trying to understand why your cross-border shipping costs are insane, you have to realize that the "zero tariff" world was always a bit of a myth. The rules have always been there; they just used to be more predictable.
Actionable Insights for Moving Forward
- Audit Your Rules of Origin: Don't assume a "Made in USA" sticker gets you into Canada tax-free. If your components are 60% Chinese, you might still face that 35% MFN rate. Verify your HS Codes and regional value content.
- Monitor the Quotas: If you're in ag-tech or food, the "within-quota" space is where the money is. Once Canada hits its yearly limit for a specific US product, the price of entry effectively triples.
- Watch Provincial Policies: Federal tariffs are only half the battle. Provincial "Buy Canadian" policies or liquor board markups can be just as expensive as a border tax.
- Expect Persistence: The dairy and lumber disputes are older than most of the people working in the trade offices. They aren't going away because of a new president or a new deal. They are structural parts of the Canadian economy.
The history of trade between these two giants is less of a straight line and more of a series of messy circles. Understanding that Canada has always protected its core industries helps make sense of the "surprises" we see in the news today. It's not a new game; the stakes just got higher.
