At the World Dairy Expo, Canadian and American farmers kept competing like always — even as some in the crowd called the trade war "needless" and "childish."

At the World Dairy Expo in Madison, Wisconsin — the most prestigious stage in competitive dairy farming — a Canadian teenager's cow was named Supreme Junior Show Champion in late September, a win that, by the standards of that world, is genuinely significant: a prize like it can add tens of thousands of dollars to an animal's value and raise the value of its future offspring. Alyson Doiron, from Cap-Santé, Que., cheered and cried as the honour was announced for her cow, Ella, calling it proof that "in Quebec, the [cow] show is really, really strong."

A rare space where the trade war takes a back seat

The Expo draws competitors from both sides of the border, and under health and safety rules, the actual judged competitions are specifically contests between Canadian and American animals. That's notable given the state of U.S.-Canada relations: with 50% tariffs on a broad range of Canadian goods, matching Canadian countermeasures, and now outright import bans on Canadian dairy, alcohol and vehicles all in effect, the dairy sector has been squarely in the crossfire of the dispute for months. At the Expo itself, CBC News reported the political tension was "more or less" set aside, with farmers from both countries focused on their animals rather than the headlines.

But not entirely set aside

CBC News still found Americans in the crowd willing to criticize the Trump administration's approach. One retired farmer, Gary Craugh, described both countries' conduct in the dispute as "childish." Brian Carscadden, part owner of the Quebec-based dairy genetics company Blondin Sires, said there had been "jokes here and there" about the trade war from his American friends at the event, and separately called the dispute "needless, pointless and childish" — notable, coming from someone whose business depends on calm cross-border relationships for its milk production and artificial insemination operations. Carscadden said his business hasn't been materially affected by the trade war yet, and that it doesn't come up often in daily conversation at the Expo — a sign that, at least for now, personal and professional relationships in the dairy world are proving more durable than the political relationship between the two countries.

The bigger picture it sits inside

The timing isn't incidental. Canadian dairy carries a 25% tariff under Ottawa's countermeasures, and outright U.S. bans on Canadian dairy products took effect in late September under Section 338 of the Tariff Act — meaning the same industry represented by farmers competing amicably in Wisconsin is, at the policy level, one of the most directly affected by the dispute. White House trade adviser Peter Navarro has warned Canada not to "interfere" with U.S. agricultural interests, saying Canada would "pay even more dearly" if it did — a considerably sharper tone than anything on display at the Expo itself.

For businesses on both sides of the dairy trade, the Expo is a reminder that personal and commercial relationships built over years don't necessarily track the political temperature in Ottawa and Washington — but it's also a reminder that those relationships exist inside a policy environment that's gotten measurably more hostile this year, regardless of how farmers themselves choose to treat each other at a cattle show.
