Canada’s long-running softwood lumber dispute with the United States has entered another chapter, with revised American duties of up to 31.11% taking effect on October 19, 2026. The new rates affect major Canadian producers, including Canfor, West Fraser and Resolute, adding another layer of financial uncertainty to an industry already struggling with trade restrictions and weakening demand.
Although the latest anti-dumping and countervailing duties are lower than some previous rates, Canadian lumber remains subject to additional American tariffs that can push total border charges considerably higher.
For Canadian forestry communities, the consequences extend beyond corporate balance sheets. Mill employment, regional economies and future investment remain closely tied to a trade relationship that has become increasingly difficult to navigate.
New U.S. Lumber Duties Take Effect After Federal Review
The U.S. Department of Commerce’s latest softwood lumber duty rates officially took effect on October 19, 2026, following publication of the final results in the Federal Register. The decision concluded the seventh administrative reviews of anti-dumping and countervailing duty orders covering certain Canadian softwood lumber products. Those reviews examined trade activity during 2024 and established revised rates for affected producers.
Canfor faces a combined anti-dumping and countervailing duty rate of 31.11%, while Resolute’s rate is 25.55% and West Fraser’s is 20.02%. Other producers covered by the reviews generally face a combined rate of 24.75%. The calculations reflect separate findings about alleged below-market selling and government subsidies.
Importantly, the decision does not represent a universal increase in duties. The combined rate for many reviewed exporters has fallen from approximately 35.16% to 24.75%, providing some relief from the previous burden. Nevertheless, the duties remain substantial, particularly for companies operating on narrow margins. The latest decision also leaves the broader trade dispute unresolved, meaning Canadian producers still face considerable uncertainty about their long-term access to the American market.
The 31% Duty Is Only Part of the Total Tariff Burden
The headline duty rate does not tell the entire story of what Canadian lumber companies face when exporting to the United States. Since October 14, 2025, certain softwood lumber products have also been subject to a separate 10% American tariff imposed under Section 232 of the Trade Expansion Act. That measure followed a national security investigation into imported wood products and operates independently of the anti-dumping and countervailing duties.
For Canfor, the combined 31.11% trade-remedy rate and additional 10% tariff can produce a total charge of 41.11% on covered shipments. Other reviewed producers generally face lower combined amounts, including 34.75% for companies assigned the 24.75% trade-remedy rate. Actual obligations depend on the exporter, product classification and applicable trade measures.
These costs matter because lumber is traded in enormous volumes, often with relatively small differences between profitable and unprofitable shipments. On a hypothetical US$100,000 shipment subject to a combined 41.11% charge, the duties would amount to US$41,110. Although lower anti-dumping and countervailing rates offer some breathing room, the remaining tariff burden can still influence pricing decisions, purchasing contracts and whether shipments remain commercially viable.
Canadian Exporters Could Face Significant Cash Flow Pressure
One of the most important consequences of American lumber duties is the way they affect cash flow. Under U.S. trade rules, the importer of record must provide cash deposits covering estimated anti-dumping and countervailing duties when affected lumber enters the country. Global Affairs Canada notes that Canadian exporters frequently serve as importers of record themselves, meaning the financial burden can fall directly on Canadian producers rather than their American customers.
These requirements can tie up substantial amounts of working capital that companies might otherwise use for wages, equipment maintenance or expansion. A manufacturer shipping millions of dollars in lumber annually must account for duties long before the final financial consequences of those shipments become clear.
The latest administrative reviews also determine final duty assessments for covered 2024 imports. Depending on the difference between the original cash deposits and the final assessed duties, companies could eventually receive refunds or owe additional payments. That creates uncertainty even after lumber has been delivered and sold. For smaller producers, unpredictable liabilities and restricted cash flow can be particularly challenging when borrowing costs, transportation expenses and market conditions are already putting pressure on operations.
The Dispute Stems From Decades of Disagreement Over Canadian Timber
At the centre of the Canada-U.S. lumber conflict is a fundamental disagreement about how Canadian forestry companies obtain timber. Much of Canada’s commercial timber comes from publicly owned Crown land, with provincial governments establishing the charges companies pay to harvest trees. American lumber producers have long argued that these arrangements provide Canadian sawmills with timber at artificially low prices, effectively creating a subsidy that disadvantages U.S. competitors.
Canada disputes the broader allegation that its forestry system provides unfair advantages. Canadian authorities have argued that differences in land ownership, harvesting systems and resource management do not automatically establish unlawful subsidization. Anti-dumping investigations raise a separate question about whether lumber is sold in the American market below its normal value.
The disagreement has survived numerous governments and several attempts at negotiated settlements. The 2006 Canada-U.S. Softwood Lumber Agreement managed trade for nine years before expiring in October 2015. The current American anti-dumping and countervailing duty orders date to 2017. For American lumber producers, the duties represent protection against practices they consider unfair. For Canadian companies, the repeated investigations create a costly and unpredictable barrier to a market that has supported cross-border trade for generations.
British Columbia’s Forestry Communities Face Growing Economic Risks
British Columbia has considerable exposure to the continuing trade dispute because of its dependence on lumber manufacturing and exports. Statistics Canada reported that the country produced approximately 47.9 million cubic metres of softwood lumber in 2024 and exported nearly 27.9 million cubic metres to the United States. The B.C. Interior alone accounted for approximately 32% of Canadian softwood lumber exports to the American market.
The consequences of declining exports are becoming increasingly visible. The Bank of Canada reported in April 2026 that Canadian lumber exports had fallen to roughly 20% below their 2024 average by February. Employment was also declining broadly alongside production, reflecting difficulties that extend beyond the latest tariff announcement.
For smaller communities, a mill closure can affect much more than the employees directly involved. In 100 Mile House, British Columbia, a sawmill that closed permanently in December 2025 eliminated approximately 165 jobs. Mayor Maureen Pinkney described how the departure of one mill worker and their spouse, who worked as a nurse, created losses for both the local economy and health services. The example illustrates how forestry downturns can spread through communities, affecting households, businesses and essential services even when those services have no direct connection to lumber production.
American Lumber Producers and Homebuilders Are Divided Over the Duties
The American lumber industry is far from united on whether tariffs are helping or hurting the country. The U.S. Lumber Coalition, which represents domestic producers and woodland owners, supports continued trade restrictions. Its position is that Canadian imports have historically disadvantaged American mills through practices it considers unfair. The coalition welcomed an October 2026 binational panel ruling that upheld an earlier U.S. countervailing duty determination.
The organization has also argued that trade protection encourages domestic investment. In May 2026, it reported that American producers had added approximately 8.6 billion board feet of softwood lumber production capacity since 2016, crediting trade enforcement as an important contributor. That represents the coalition’s assessment rather than proof that tariffs alone produced the expansion.
American homebuilders see the situation differently. The National Association of Home Builders warned on October 16 that the newly reduced duties still leave many Canadian lumber imports facing combined charges of 34.75%. The organization argues that these costs undermine housing affordability by increasing building expenses. It has called for the removal of lumber tariffs and a new agreement with Canada, illustrating how policies intended to protect one American industry can create financial pressure for another.
Ottawa and Ontario Push Back as Canada Expands Forestry Support
Canadian governments have rejected the argument that reduced American duty rates resolve the dispute. On October 14, Ontario officials described the duties as unjustified and maintained that they hurt workers, businesses and consumers on both sides of the border. The province acknowledged that the reduction to 24.75% offered some relief, but continued calling for the elimination of softwood lumber duties and a lasting bilateral agreement.
Ottawa has also introduced substantial financial assistance to help the forestry industry withstand trade disruptions. By December 2025, the federal government had announced more than $2.35 billion in measures supporting the sector. These included $1.2 billion in available loan guarantees through the Business Development Bank of Canada and $500 million earmarked for larger forestry companies experiencing liquidity pressures.
Other initiatives focus on protecting workers and reducing dependence on traditional lumber exports. Federal measures include $50 million for training and employment support for more than 6,000 affected softwood lumber workers, alongside $500 million for forest-sector transformation programs. Ottawa has also promoted greater use of Canadian wood in domestic construction and infrastructure. These initiatives may help companies adapt, but financing and new investment cannot immediately replace the commercial opportunities provided by unrestricted access to the American market.
Recent Trade Panel Decisions Show the Legal Battle Is Far From Settled
The latest duties arrive amid another series of legal developments involving the long-running lumber dispute. On October 5, 2026, a binational panel established under the former North American Free Trade Agreement upheld the U.S. Department of Commerce’s second redetermination concerning its original countervailing duty findings. The decision effectively concluded that particular Canadian challenge, representing a significant outcome for American producers supporting the duties.
However, a separate panel operating under the Canada-United States-Mexico Agreement reached a more mixed decision on October 8. Reviewing an earlier countervailing duty administrative determination covering 2017 and 2018, the panel upheld some aspects of Washington’s findings while sending others back for reconsideration. Neither ruling directly determines the new rates effective October 19.
The distinction matters because several generations of duty assessments and legal proceedings can remain active simultaneously. A successful challenge involving one review does not necessarily overturn duties established through another. Canadian producers therefore face overlapping legal, financial and commercial questions, with decisions involving older shipments continuing alongside newly calculated obligations. Until both countries establish a more predictable arrangement, companies may have to make investment decisions without knowing what future annual reviews or legal challenges will ultimately mean for their costs.
Canada’s Lumber Industry Faces Difficult Choices Beyond the Latest Tariffs
The longer-term challenge is reducing Canada’s exposure to a single export market without abandoning customers who remain essential to the industry’s survival. American demand has shaped Canadian lumber production for decades, particularly in British Columbia. Markets such as Japan, China and South Korea offer alternatives, but reaching distant customers involves additional transportation expenses, competition and differences in construction requirements.
Industry leaders acknowledge that expanding overseas sales will not be easy. In October, the BC Lumber Trade Council highlighted how domestic operating costs and regulatory pressures were making Canadian lumber less competitive internationally. The Bank of Canada has similarly identified high transportation costs as an obstacle to businesses trying to diversify away from the United States.
A stronger domestic market could provide another opportunity, particularly through increased housing construction and more advanced wood products such as mass timber and engineered building components. However, developing new markets and manufacturing capacity requires time and sustained investment.
Meanwhile, the next round of American administrative reviews is already underway, leaving the prospect of further duty changes in 2027. Although the latest reductions provide some financial relief, they do not resolve the fundamental disagreements between the two countries. For Canadian producers, the central issue remains whether North America’s integrated lumber market can regain the stability needed to support investment, competitive prices and long-term employment.
