WASHINGTON, D.C. — The Canada-U.S. softwood lumber trade relationship has dealt with ups and downs, disputes and resolutions, for decades. Anxiety for Canadian exporters is reaching a fever pitch again as the U.S. threatens to more than double softwood lumber duties and add even steeper tariffs under a national security investigation.

Canadian foresters, mills, and governments that enjoy taxes, economic spinoffs and stumpage fees from Crown land will feel the pain if they lose too much access to the massive U.S. market. But larger producers have been preparing for just this kind of contingency and have cleverly hedged their bets, building capacity in the U.S., where they can sell as much as they want to Americans, tariff-free.

Canadian firms will soon receive word from the U.S. Commerce Department's Sixth Administrative Review (AR6) of U.S. countervailing and anti-dumping duties on Canadian softwood lumber exports, with the rate expected to jump from around 14 per cent to roughly 34 per cent. For Canfor, the Vancouver-based lumber giant selected as a mandatory respondent in the AR6 review, it will be even worse. Its duties are calculated based on its own shipments and prices, not an industry average, like it is for other companies.

Then there's the threat of tariffs from President Donald Trump's ongoing national security investigation of Canadian lumber imports under Section 232 of the Trade Expansion Act, which he ordered in March and is due late this year. Currently, lumber shipments are exempted from Trump's baseline tariffs, because they're covered by the U.S.-Mexico-Canada trade deal (USMCA), but that could soon change based on the findings of the 232 probe.

What American producers want

The U.S. Lumber Coalition is playing for keeps. It backs higher anti-dumping duties and tariffs for what it sees as a subsidized domestic industry. It claims Canadian producers don't pay market rates for stumpage because their forests are publicly owned and provincial governments set the stumpage rates, while U.S. producers face higher market rates. But it doesn't stop there: the U.S. coalition also wants to see Canada's U.S. market share significantly chopped.

Today, Canada has a 25 per cent market share, with exports of 12 billion feet of softwood lumber to the U.S. each year, according to the coalition. Softwood lumber accounts for about 7.5 per cent of Canadian exports; in 2023, the U.S. was the destination for 68 per cent of those forestry products. The whole industry is worth about $33.4 billion in sales annually and employs more than 200,000 workers across Canada, according to a report this year from RBC.
