US Lumber Coalition Calls on Trump Administration to Enforce Strict Tariffs on Canadian Imports

WASHINGTON, August 11, 2026 — It turns out that flying provincial delegates across the globe to pitch Canadian timber to non-U.S. buyers does not actually work if the math is fundamentally broken from the start.

Statistics Canada recently confirmed what trade watchdogs have suspected for a while now: Canada’s heavily promoted market diversification scheme is falling flat on its face.

Over the last six months, Canadian lumber shipments to non-U.S. markets have slipped yet again, proving that northern mills are more hooked than ever on unloading their massive, subsidized excess into American yards.

So, the math here—if you really sit down and look at the actual numbers—it just does not add up for Canadian exporters. Canada has built an absurdly over-engineered forestry machine. The country produces roughly 27 billion board feet of softwood lumber annually, yet its domestic market only consumes about 7 billion.

That leaves a massive, structural surplus of 20 billion board feet that has to go somewhere. Since they cannot find alternative buyers, nearly 90 percent of that excess capacity gets dumped straight into the United States, effectively undercutting American mills that do not enjoy the same government safety nets.

That safety net is not exactly pocket change.

According to the U.S. Lumber Coalition, Canadian provincial governments have dished out an estimated C$2.57 billion in forestry-specific subsidies, alongside a staggering C$9.9 billion in broader sector aid since August 2025 alone.

It is a massive war chest that allows Canadian producers to keep operating even when market prices dictate they should probably be scaling back.

“President Trump holds the key to addressing Canada’s massive excess lumber capacity,” says Zoltan van Heyningen, Executive Director of the Coalition, in the group’s latest trade update.

He argues that the solution lies in a mix of aggressive antidumping enforcement, countervailing duties, and the administration’s Section 232 tariff measures.

The real kicker is that Canadian producers have seemingly become addicted to the U.S. market, and they expect American builders to absorb their overproduction indefinitely.

The U.S. domestic industry is finally starting to claw back some ground.

Thanks to the heavy duties slapped on imports over the past year, we are starting to see the very early stages of what economists call a “right-sizing” of the Canadian timber sector.

If the Trump administration maintains its current aggressive stance, domestic producers argue they can fully supply the U.S. market using American-grown trees, rather than relying on subsidized imports to build American homes.

Whether the domestic industry can scale up fast enough to prevent a spike in home construction costs is still a matter of fierce debate among builders.

But for now, the U.S. Lumber Coalition is making it clear that they expect Washington to keep the trade screws tight, regardless of how loud Ottawa complains about the tariffs.
