Idaho sends nearly 40 percent of its total foreign exports to Canada, making the U.S.-Canada trade dispute that took effect August 22 a more immediate economic concern for the Gem State than for most others. With billions in two-way trade now subject to new tariffs, Idaho businesses and agriculture producers face rising costs and uncertain market access.

Idaho’s Deep Trade Ties with Canada

Canada is Idaho’s largest foreign trading partner by a significant margin. The state shipped $1.8 billion in goods to Canada in 2025, accounting for 39 percent of all Idaho foreign exports. Traffic flows the other direction too — Idaho imported roughly $1.2 billion in Canadian goods over the same period.

Robert Spendlove, an economist with Zions Bank, described the relationship as unusually robust. “We annually export $1.8 billion in goods to Canada, and then we import $1.2 billion in goods from Canada,” he told the Idaho Press. “It’s a really strong trading relationship.”

Agricultural products make up about a quarter of Idaho’s Canadian exports. Through the first half of this year, the state had already sent $256 million in food and agricultural goods north of the border, including $119 million in live cattle exports alone. Canadian commodity receipts from Idaho reached $444 million in 2024 and climbed to $455 million in 2025.

What the Tariffs Cover

The federal government imposed tariffs as high as 50 percent on $27.6 billion worth of Canadian goods, with those measures taking effect August 22. Canada responded with its own counter-tariffs ranging from 15 to 50 percent on the same dollar value of U.S. imports.

For Idaho, the import side of the ledger is also significant. Among the state’s top goods brought in from Canada are animal feed and industrial residues — valued at $86 million annually — along with softwood lumber at $86 million and fertilizers at $56 million. Increased costs on those inputs ripple through Idaho’s farming, ranching, and construction sectors.

Spendlove outlined the two possible economic outcomes in straightforward terms. “Either we see higher inflation,” he said, as reported by the Idaho Press, “or we see decreased economic activity.” July’s Personal Consumption Expenditures price index already showed annual U.S. inflation at 3.7 percent, a data point that economists say could worsen if tariff-driven cost pressures persist.

A Border State’s Perspective

Few Idaho officials feel the Canada relationship more acutely than those in the northern panhandle. State Sen. Jim Woodward, a Republican from Sagle who represents the Bonners Ferry area just south of the international border, represents constituents whose daily lives and livelihoods are intertwined with cross-border commerce.

The geographic reality of northern Idaho means that economic disruption to the south — and pressure on Canadian counter-tariffs — isn’t an abstraction. Communities there rely on Canadian timber, agricultural inputs, and trade corridors that have developed over decades.

Columbia River Treaty Adds Complexity

Trade tensions are not the only friction point between the U.S. and Canada affecting Idaho. Negotiations over a revised Columbia River Treaty have been on hold since March 2025, when British Columbia’s Energy Ministry confirmed the American side had paused talks. An in-principle agreement for an updated treaty had been reached as recently as July 2024, making the subsequent stall a setback for both countries.

The Columbia River system is central to water management, hydropower, and flood control across the Pacific Northwest. The International Kootenay Lake Board of Control, which governs water levels on Kootenay Lake and the Kootenai River, operates within the broader cross-border framework that the treaty governs. A prolonged negotiation breakdown adds another layer of uncertainty to U.S.-Canada relations that already affect Idaho directly.

What Comes Next

The durability of the current tariff structure remains unclear. Federal negotiations could modify or lift the levies, though no timeline has been announced. Idaho’s congressional delegation, including Rep. Mike Simpson, who has worked to direct federal resources toward Idaho’s agricultural sector, will face pressure from industry groups to advocate for relief or exemptions on goods critical to the state’s economy.

For now, Idaho exporters — particularly in agriculture and livestock — are watching commodity prices, Canadian buyer behavior, and any signals from Washington about the direction of trade policy with the country that buys more Idaho goods than any other.
