Why Trump’s New Tariff Is Bigger Than Canada | Diving In
Trump's new 50% tariffs on Canada bypass USMCA — here's what it really means for you.
President Trump just hit a limited set of Canadian goods with 50% tariffs, and he did it by dusting off Section 338 of the Tariff Act of 1930 — a law last used when Herbert Hoover was in the building. Justin Wolfers walks you through what actually happened, why it's stranger than it sounds, and why the direct cost to the U.S. is smaller than the message behind it.
Here's the twist: throughout the earlier trade wars, being compliant with the USMCA free trade agreement was your escape hatch — roughly 90% of Canadian goods came in duty-free. These new proclamations ignore that agreement entirely. Justin's quick-and-dirty math says the tariffs cover a bit more than $20 billion of imports, about 5% of what we buy from Canada — meaning maybe $50 to $150 a year on your household, plus higher prices from American firms that now face less competition. For Canada it's a real hit: close to 1% of GDP.
But the bigger story is confidence. If a signed trade deal only holds until the next presidential mood swing, it's not really a rule. Justin argues Canada is the test case — a warning to the roughly 60 countries facing new tariffs any week now: retaliate, and your trade deal may not save you.

President Trump just hit Canada with a new set of tariffs in their big fifty percent. Look, this is a big deal. He's sending a message to every other country watching. They're waiting for the next round of the global trade war. The message is simple. It's not actually about Canada. It's this. It's if you retaliate, your trade deal may not save you. Canada was just the first one to find that out. So, yes, this is a story about a fifty percent tariff on Canadian goods. We'll get into that. But it's also a story about whether executive power can be used this way, about America's place in the world, about whether we the United States, is capable of coming to terms with and living up to a trade agreement, and about what the White House may be trying to signal to every other trading partner right now. Fundamentally, it's a story about the future of our economy. Now. It matters for American family because ultimately, what the President's doing is imposing taxes on Americans. He's imposing taxes on Americans who buy stuff from Canada, another way of saying you, you are paying these taxes. It also matters for Canada. My rough instant analysis, and it's very quick and dirty, says, this is a much bigger deal than the president's most recent volleys in our on again, off again trade war with our nearest neighbor. And it matters for the rest of the world and our relationship with the rest of that global economy because the next round of the trade war, it's just around the corner. Okay, So what actually happened yesterday? That was July twenty The White House posted three proclamations using what's called Section three hundred and thirty eight of the Tarifact of nineteen thirty And if you'd never heard of it before, don't worry. It was on no one's bingo card. This was a very surprising legal theory. Each one of these proclamations slaps an extra fifty percent tariff on a different list of Canadian goods, and those tariffs they're set to come into effect in a month's time. Given the President and he's on again, off again nature of all of this, when he says something's going to happen in thirty days time, that either means it will happen in thirty days time or it won't happen in thirty days time, or there'll be a lot of drama between now and thirty days time. Take your pick. These disputes, they have these labels. They're officially over motive vehicles, alcoholic beverages, and dairy. Look, there's going to be a lot of ink spilled over these disputes, and you might ask, what is our real beef with Canadian dairy, booze and cars. Let me save you the time. The dispute over dairy and boos they're economically tiny. They barely matter for the US economy at all. The motor vehicle thing, it's a bit bigger. But it's really about Canada having retaliated in response to Trump's trade wars. So he tried tariffs. They they send a few back, and the President's upset about here that Look, there's really not much here to these particular complaints other than a desire to punch Canada dressed up in a novel legal theory. But this punch, this set of punches, is different. The White House says that these tariffs hit the list of goods, whether or not they qualify under our existing free trade agreement with Canada, that free trade agreements called the USMCA. Let me put that in plain English. Even if a Canadian good ticks every box in order to deserve or warrant preferential treatment under our existing free trade agreement, the White House has said, we're not going to give you that preferential treatment the free trade agreement we signed. We're just going to ignore it. Now, why does that matter so much? He needs to know a bit of history. If the US Canada trade war of twenty twenty five and twenty twenty six, because there was a lot of tariff chaos early in Trump's second term, I'm sure you remember it, but having your goods be compliant with the existing US Canada Mexico free trade agreement was actually really important to skate patch. So throughout twenty twenty five, the White House was throwing around these tariff threats would reckless abandon, but would also quietly ad an asterisk, saying that these threats would apply to every country and every good, oh, except for those from Canada and Mexico that would qualify under our existing free trade agreement. It was a special deal for our nearest neighbors, I think, mainly to try and reduce some of the economic havoc that the trade wars were causing. Well, this turned out to be a really important eskate patch because almost all of the Canadian trade that was caught up in those earlier fights actually qualified has been compliant with our existing free trade agreements. A Canadian Finance Department briefing said ninety seven percent of Canadian exports covered by those earlier tariffs were KUZMA compliant. Came in Judy three. KUZMA. What's that, Well, that's what the Canadians call the USMCA. It's not a French translation. They just have different laws up there, but it's the Canadian name. It's the same deal, different name. So look, the rough version is something like ninety percent of Canadian goods were exempt from all of the machinations of the Trump trade war. Our relationship with Canada. The rhetoric was bad, but the reality was that we were trading pretty well with Canada throughout the trade war. Basically, the message was that if you get your paperwork right, if you qualify your product, then you get shelter from the storm, the president, of course being the storm. Now the message is for this list of goods, the shelter doesn't work anymore. And that's why this is a much bigger deal than it might sound like at first. Now I probably need to give you a bit more history about what's going on here, And honestly, the history here is so absurd that the best thing I can do is just line the facts up and let them do the comedy for you. First of all, Trump spent his first term telling everyone that NAFTA was a disaster, and n after was the free trade agreement between the US, Canada and Mexico negotiated by President Clinton, passed by Congress. So the first president Trump renegotiated it. Then he announced the replacement that was called USMCA rhymes a bit with YMCA, one of his favorite songs, and he announced it like he discovered fire and fentted trade and personally rescued North America from him a deal that the United States had. This is the awkward bit, the embarrassing bit. We had noticeably already been in the free trade deal with remarkably similar rules for decades. The President, of course, held a whole new signing ceremony. There were flags, people applauded, there were sharpies, but nothing really changed except the branding. We now had new initials for our new free trade agreement with Canada, but it was basically the old one with a new dressing. President Trump got elected again, and so in the second term he decided he really hated that agreement that the first President Trump had struck with Canada, and he kept eating Canada with tariffs anyway, and then he adjusted them, and then he would carve out USMCA compliant goods. Then he slapped sectoral tariffs on other stuff, and then he kept telling everyone that the trade agreement that inherited from his incompetent predecessor that was President Trump wasn't very good anyway. And so now here we are again, same president reaching for a law from nineteen thirty to tariff Canadian goods even when they qualify under the trade agreement that replaced the trade agreement that he blew up in order to write this trade agreement. Look, this isn't really trade policy. This is a man negotiating with himself, with his ego and with his poor understanding of what's really going on. He wanted to write a deal to replace the deal that he blew up because he hated the deal that he'd been in. But effectively that original deal is still where we are it's all just NAFTA with another name, and this White House can't stop, won't stop. The White House recently said it's not going to agree to renew the USMCA, that's the one that President Trump renegotiated. They're not going to renew it in its current form. This is more nonsense and more misdirection, because if the three countries don't agree in the twenty twenty six review to extend the deal for another sixteen years, if they don't agree to a sixteen year renewal, then the agreement, which passed Congress and his law in the United States, it doesn't just vanish tomorrow. It stays in force. It shifts from look, we agreed to a sixteen year renewal to annual reviews. So every year now it's up for renewal. And if every year they fail to extend the agreement, guess what, it just continues. And it's going to continue this way until twenty thirty six. So when the President says he hasn't agreed to renew the deal, that just means he's not agreed. But he goes to his earlier agreement, which is that we automatically renew the deal and we're going to continue to do so for another teen year. So what's happening. In reality? We have a trade deal which keeps renewing, which past Congress, but also in a different reality, the President's does it off this nineteen thirty law to say, effectively, we reserve the right to treat the deal as purely optional whenever it gets inconvenient, even though Congress passed it. Yes, the courts are going to get involved. Look, I know that trade agreements are always a mix of rules and politics, and fair enough, I get that the whole point of signing one. Well, really, the whole point of signing one is to create and understanding you and your partner can rely on each other. A trade agreement's meant to be like a marriage vow. It's for better, for worse, for richer, for poorer, and sickness and in health. And when you marry someone you can invest more deeply in your relationship knowing that they're going to be there for you and with you under those terms in the future. But mate, if NAFTA or the UMCA or whatever we're calling it these days, as a marriage this has turned into an abusive marriage. Now it turns out that the latest renegotiation, by which I mean the President deciding he's going to issue literally dozens of pages of new tariffs ends up looking incredibly weird. And that's because we're going to need to talk about the novel legal theory behind our new trade war with Canada on a remind you, I'm not a lawyer, so I'm just going to sketch out the big details. Okay, big picture. Remember, the Constitution gives Congress, not the President, the power of a tariffs in the US was formed at a revolt over taxes. We thought the people's house, rather than the king, should handle taxes. So the Constitution gives all the default powers over tarifts to Congress, which means if the President is going to do something without Congress, and that's his determination he's decided to do, none of the Trump trade war has gone through Congress. Means he has to pretend that somewhere along the line Congress gave him the power to host tariffs. Now, the courts have really forced President Trump to pay attention to this, and the Supreme Court ruled many of his existing tariffs unconstitutional and illegal because they didn't come from Congress. So these new anti Canada proclamations. They learn on what's called section three hundred and thirty eight of the Tariff Act of nineteen thirty. This isn't normal trade law plumbing. This is the White House heading down into the basement to find an old wrench. It's a dusty, old trade war wrench from nineteen thirty. It was last years when Herbert Hoover was still in the building. Section three hundred and thirty eight, let's the president slap additional duties on a country of up to fifty percent if he finds that another country discriminates against US commerce, or if it piles an unreasonable unequal burden on the United States, and the law says that the tariff should offset that burden or disadvantage. So the statute reads at least a bit like it's a retaliation tool, but it's not a free floating smash whatever you want button. And the modern analysts that I've looked at they read it the same way. There was a February twenty twenty sixth briefing from my friends that the Peterson is for International Economics, which called section three thirty eight quote an untested retaliatory tool and said that it had never been used to apply to a tariff, although it has been threatened that way over the years. It does sound like though it's meant to invoke some degree of proportionality in the response. So look this law. It is weird. It's a weird way of moving forward. And that weird law is where you get a weird list of the things that the United States now is going to taraf Again, I want to remind you, let's go back the proclamations from the President say we've got a complaint because we've got dispirites around cars, around alcohol, and around dairy. Now, it doesn't mean that in return, we're going to put tariffs on cars, booze, and milk or cheese. But what we're actually going to do is hit a random rab bag of goods that the US imports from Canada. So there's a long annex, many pages that tells you what goods we're going to hit. Now, the White House has carved out a bunch of stuff that it says we really want from Canada. We're not going to tariff those things. That's energy, pittash, critical minerals, certain aircraft goods, and everything that's already under Section two thirty two tariffs. So what you end up with, for instance, is a proclamation about our complaints about how the Canadians are treating American cars, and then we're going to impost tariffs on all sorts of things that have nothing to do with cars, so honey and flowers and cement and plastics and furniture and telecom gear. Basically, US tariff policy has discovered the US Canadian junk draw and that really is the explanation for what's going on here. Okay, what about the economic effects, I think mostly relatively small direct effects for the United States, real money for Canada. And what really matters is what it's going to do to the Americans, America's place in the world. So let's do some arithmetic. And I want to show you a little bit of modesty here. I don't have a polished, huge quantitative model of what's going on here. I've just got a day one snap instant analysis which I'm just going to try to get the orders of magnitude right. What's going on here? My raugh estimate is that the tariffs that are listed o but literally dozens of pages of a presidential proclamation. I want to note to you, by the way, the White House never says anything about what they think the economic consequences will be. That apparently is a secret. Maybe they did their homework and they aren't telling us. Maybe they never did any homework and they don't care. But my analysis says that these tariffs will probably cover a bit more than twenty billion dollars of goods that come from Canada into the United States. That's maybe round about five percent of what we import from Canada. So it's meaningful without being huge, that five percent big plus or minus around it. So for the United States, my reader is basically feeling modest macro canomic effect with very real microeconomic consequences. Roughly speaking, it might cost the typical American household fifty bucks, maybe one hundred bucks, maybe one hundred and fifty bucks a year. All that's going to depend on what you want to your economic assumptions about pass through substitutions. And they think, importantly, when we have less competition from Canada, it doesn't just hurt Americans who buy stuff from Canada, because that means less competition for American firms. And so some American firms now face less competition and they might jack up their prices too, So the effects here are meaningful, but not giganty. My friends in Canada, and yes, you are still my friends. I have a brother who lives in Canada. I love him very much, but I love all my Canadian friends. This surreal hit. It's not because it covers all exports. It doesn't. But roughly speaking, this is going to apply to something like three percent of Canada's total exports across all countries. It's nearly one percent of GDP the export of these goods to the United States, and all of a sudden, there's a fifty percent tariff wall. Look, that is the sort of thing the businesses are going to notice, exporters are going to notice, the provinces are going to notice. So all of this is going to create uncertainty above and beyond the specific tariffs that the President is listed. I want you to realize, though, that this is a slice. It's a meaningful slice, and compared to a lot of what was happening earlier in Trump's second term, where there was the escape patch, that escape patch has gone. There's a very real and very genuine escalation from the United States here. And let me tell you beyond just the spreadsheet lines and the numbers and the industries that are affected. I've been talking with my Canadian family, with my Canadian friends, Canadian journals, have been reading the Canadian media, and let me tell your folks, they are mad. They are hopping mad. It's not just that they see this as unfair. It's not just that they see that their free trade agreement has been breached again rebreached. Is that they see themselves as being treated poorly, as a horn in the game, as President Trump not taking the relationship remotely seriously. They, let me tell you, are sick of this. I've talked to Canadians have said they will never come to the United States again, They will never buy an American made product again. None of that is stuff you can deal with in a trade agreement. This is a population who are sick and tired of the United States, and individually they want to retaliate. And many of them are saying to me, why Canada, Why now? And I think this is an important question on both sides of the border. Look, some part of what the administration is saying as plause will a lot of it as not the dairy dispute. It's probably the cleanest rationale on its own. The US has been whining about the way Canada runs its dairy tariff quotas for years. The Americans don't like it. Here's the flip side. The other side is, this is a tremendously powerful political lobby in Canada. Here's the real dirty work of how trade deals work. The Americans are meant to get in a room with the Canadians and they meant to say, let's try and free up trade. And basically that's how both NAFTA and USMCA works. And then both sides sort of said, you know what, I've got a few political problems at home. I can get most trade freed up and we can have a pretty good relationship. You're gonna have to give me a couple of mulligans here because there's a few industries it's not worth the political headache. And the Americans list, there's the Canadians list, there's and what you end up with is never perfectly free trade, but mostly free trade. The US dairy industry is one of those areas where it's just going to be too hard for the Canadians to get it done. I think they should. I wish they would, but if I were in charge, of US trade policy. I would understand this as part of Look, they're most of the way there. Here's a tiny, economically insignificant industry to the United States, which is politically very important in Canada. And so this is the sort of thing where you know, it's just good grace in a trade agreement to just quietly admit there's a little bit of politics that makes us difficult to get to the perfect economic agreement, and so you know, having a trade agreement doesn't make those politics disappear. The alcohol dis it's smaller and it's more provincial. It's basically dug Ford doesn't like Americans buying Canadian wine. He wants to punch back, and some of the other provinces have done that as well. It's not coming from the national government. The motor vehicle fight. It's all tied up with earlier rounds of tariff from the United States and retaliation and retaliation from retaliation. I think the point here is, though, is if you step back from the legal labels and the novel legal theory here and ask what's the broader play that we're seeing here, I think the answer is it's bigger and dairy. It's bigger and booze, it's bigger in cars. In fact, my interpretation, I want to be clear, this is an interpretation. It's mine. It could be wrong, it's probably right. That's why I'm telling it with Yeah. My interpretation is that actually it's not about Canada. That Canada is the test case. It's the punching dummy that we're going to beat up. See, the White House has gone out of its way to point out that the only two countries that retaliated against the United States were Canada and China, and that it went out of its way to note that that's not just a complaint, that's a message, and I think you've got to hear that message in the context of whatever's coming next in your global trade war. The administration is really right on the cusp of imposing a whole new set of tariffs on all of its major trading partners, sixty countries. I've made another video about they'll try and link that below. But basically, it's got another legal theory. It's all about forced labor. I don't believe it's got anything to do with force labor, but it's got another legal theory where it thinks it can reimpose tariff's on the rest of the world. Those new tariffs are coming any week now, which means that any week now other countries around the world are facing a moment of truth should they retaliate against the United States. And I think the answer is that the United States is trying to say, Hey, look out, if you retaliate against US, boom, We're coming right back at you. So by this view, these tariffs, they're not about Canada. They're actually about the next round of the global trade war. Hey, I want us to slow down, step back, and really see the big picture here. Because the big picture and the lesson I really want you to take away from this is the value of a trade agreement isn't in what the text says, just like the value of a marriage agreement is beyond the precise promise you say it out loud on your wedding day. It's more about whether the institutions actually hold the people in charge to what they say they've agreed to. If a deal only protects you until the next presidential mood swing, then what you've got isn't really a rule. It's just a junk drawer. It's a junk draw full of old wrenchers and honey and hockey sticks and whatever else. Someone decided to grab that moment and tariff that afternoon
