Tuesday won't save Canada from Trump — and that's the point

More than 53 million Americans had already voted by Sunday morning, according to an analysis by the University of Florida's Election Lab, smashing the 2022 early-vote total of 45.9 million before Election Day had even arrived. That is not a footnote. It is the sound of a country that has decided this election matters, and Canadians should be listening closely — because Tuesday's vote will be read in Ottawa, fairly or not, as a verdict on the trade war strangling our exporters.

Here is the uncomfortable part, and it is worth saying plainly before the results roll in: Tuesday probably will not save Canada. It might help. It might change the temperature in Washington. But the tariffs crushing Canadian steel, autos and manufacturers are not set by Congress. They are set by a president who has made them the centrepiece of his economic policy, and no House majority can simply vote them away.

Start with what Tuesday can actually do. All 435 House seats are on the ballot, along with 35 of the 100 Senate seats, according to election trackers. Polling reported alongside the early-vote figures puts Democrats at 51.5 per cent nationally against 43.1 per cent for Republicans, and prediction-market reporting has Democrats as overwhelming favourites to take the House. A Democratic House could investigate, subpoena, embarrass and obstruct. It could refuse to fund parts of the tariff machinery. It could give Canadian diplomats allies with gavels instead of just sympathy.

What it cannot do is sign a trade deal, repeal duties by itself, or force a president to stop liking tariffs. The Senate is the harder wall. Republicans defend a 53–47 majority, and even optimistic Democratic scenarios run through a handful of knife-edge races. Texas is the most startling of them: more than seven million Texans had already voted early, about 1.5 million more than in the entire 2022 cycle, according to the Election Lab figures reported by The Guardian. The state's open Senate seat, held by Republican John Cornyn, has become a genuine toss-up, with Democrat James Talarico and Republican Ken Paxton separated by two points among likely voters in the Marist Poll's October survey, at 47 per cent to 45 per cent. Other surveys tell the same story of a dead heat: Emerson College had Talarico up 48 per cent to 46 per cent, while a Fox News poll had the two tied at 49 per cent apiece. Even if Democrats run the table in Texas, Maine, Alaska and Kansas, a Senate majority would still leave the White House in the hands of a man who treats tariffs as revenue, leverage and identity all at once.

Prime Minister Mark Carney has said this out loud, which is to his credit. He told Politico he would not sign a bad deal even if that meant waiting for a new president, answering, "if that's what it takes, yeah," when asked whether he would hold out until the next administration. In a separate interview with Montreal's La Presse, he said he did not expect Tuesday's results to significantly change Trump's trade policy, adding, "This administration has no agreement with any country that does not include tariffs. That's the reality. The question is how high the tariffs will be." That is a bleak sentence from a prime minister whose job depends on optimism. It is also, on the evidence, correct.

Consider the counter-argument, because it deserves a fair hearing. A Democratic Congress could matter at the margins that decide real business decisions. Tariff relief for steel and autos — the two files Ottawa and Washington have actually been discussing — does not require a grand treaty; it requires political permission inside the administration to grant exemptions. A House that spends 2027 hauling tariff policy into hearings, and a Senate map that forces Republicans in Maine, Michigan and Alaska to defend the costs their own voters are paying, changes the cost-benefit math for a White House that watches elections closely. Trump has already adjusted some Canadian tariffs to help Maine Republican Senator Susan Collins, who faces a difficult re-election fight after nearly three decades in the seat, according to reporting on the campaign. Politics moves this president. Congress is one of the few forces that can move his politics.

But note the limits of that hope. The same reporting shows the mechanism working in reverse: tariff tweaks as campaign favours, granted and withdrawn with the electoral calendar, are not a trade policy. They are patronage with a customs form. And Democrats, for all their opposition to Trump's methods, have not promised to dismantle the tariff edifice itself. Tariffs as industrial policy and revenue now have a constituency in both American parties, and Canada cannot build its future on the assumption that the next American government will be dramatically different from this one. That is the real lesson of Tuesday, whichever party wins: the United States has become an unreliable partner by choice, not by accident, and unreliability does not get fixed by one election night.

So what should Canada do with a result that helps but does not save? The answer is already visible in what Ottawa has done while waiting. Carney has pushed to make Canada the European Union's first associate member, launched a new alliance with the bloc, and set a goal of doubling exports outside the United States over the next decade. That diversification is not a consolation prize for a failed American relationship; it is the main event. A Democratic House, if it comes, should be treated as a useful tailwind for that project — more hearings, more pressure, more exemptions to pocket — not as a rescue that lets Canada stop diversifying.

There is also a domestic honesty test here. Canadian politics loves to outsource hope to American elections. It is comforting to believe that the right result in Texas or Maine will reopen the border to normal commerce. But the steelworker in Hamilton and the auto-parts maker in Windsor do not get paid in American polling averages. They get paid when Ottawa builds markets that do not depend on one man's mood, when it finishes the infrastructure that lets Canadian goods reach other oceans, and when it stops treating each tariff tweak as a breakthrough. Tuesday's vote matters enormously to Americans. For Canadians, its greatest value may be as a reminder: the cavalry is not coming, so we had better keep building our own way out.
