Autumn arrival of Maison Canada in Ottawa to promote increased local timber procurement
==============================================================================
In a significant escalation of trade tensions, tariffs on Canadian lumber imports into the United States have risen significantly. As of August 2025, the combined duties now exceed 35%, following increases in anti-dumping and countervailing duties [1][3][5].
The U.S. Commerce Department raised anti-dumping duties from 7.66% to about 20.56%, added countervailing duties increasing from 6.74% to a probable 14.38%, and the total combined rate is expected to be around 35% once final reviews concluded on August 8, 2025.
These duties apply on top of preferential treatments under USMCA, which may exempt some goods. The U.S. initiated an investigation under Section 232 of the Trade Expansion Act to determine whether Canadian lumber imports pose a national security risk, which could lead to even higher tariffs [1][3].
The dispute stems from the U.S. view that Canadian “stumpage rates” (fees for harvesting timber) are artificially low, though Canada and the WTO have largely disputed this claim [3]. In response, Canada has announced a $1.2 billion aid package for its softwood lumber industry to counterbalance the U.S. duties [5].
About two-thirds of Canada's lumber production goes to the United States, making this industry a significant player in the Canada-U.S. trade relationship. However, lumber is an exception to most Canadian goods that can avoid these tariffs [2].
The broader Canada-U.S. trade environment has also seen tariffs on steel and aluminum imports (25% tariffs imposed by the U.S. starting March 2025), with retaliatory tariffs announced by Canada, creating overall trade tensions [2].
Prime Minister Mark Carney has indicated specific aid programs would be put in place for sectors most affected by these new American tariffs, including softwood lumber and the automobile industry. The Quebec government has invested over $1.6 billion to support the wood industry [4].
The Liberal platform proposes $25 billion in financing for innovative prefabricated house builders in Canada, using Canadian technologies and resources such as mass timber and lumber [2]. Canada is the second largest producer of lumber in the world [2].
The ongoing Section 232 investigation outcomes and possible further escalations in tariffs or trade restrictions by the U.S. could potentially lead to future changes in this situation. Meanwhile, Canada is pursuing diversification of markets, homebuilding programs prioritizing Canadian materials, and worker retraining to mitigate the impact [3].
| Tariff Type | Previous Rate | New/Expected Rate (2025) | |---------------------------|---------------|---------------------------| | Anti-dumping Duty | 7.66% | ~20.56% | | Countervailing Duty | 6.74% | ~14.38% | | Combined Total Duty Rate | ~14.4% | ~35% |
These changes reflect ongoing trade tensions and the U.S. government's aggressive enforcement approach on Canadian lumber imports [1][3][5]. The St-Michel sawmill in Lanaudière temporarily closed due to the lumber tariffs, resulting in the layoff of over 250 workers for three months [6].
The Canadian government is promising $700 million in loans to liquidity-strapped businesses in the wood industry [4]. Quebec Minister of Natural Resources and Forests, Maitreé Blanchette Vezina, has stated that the wood industry supports over 200,000 jobs across Canada [7].
Canadian Prime Minister Mark Carney announced measures to aid the lumber industry on Tuesday [7]. The Quebec Forest Industry Council praised the government's willingness to provide liquidity to companies awaiting tax refunds and a resolution to the conflict with the United States [8].
The Canadian government is providing $500 million in subsidies to diversify the wood market, including development of low-carbon wood and transformation into new construction materials [8]. Ottawa has already announced a plan to help the steel industry and has promised another for the automobile industry [9].
The Canadian government has imposed a 25% surtax on the import of various American consumer products since March 4 [9]. Ottawa has collected additional revenues of $617 million in March, $828 million in April, and $686 million in May due to these new tariffs [9].
