Producer
Interfor Corporation
Canadian softwood lumber company (TSX: IFP, HQ Vancouver BC; ~C$3.5B revenue); produces SPF dimension lumber from sawmills in British Columbia, Alberta, and the US South and Pacific Northwest. Interfor has pursued an active US sawmill acquisition strategy since 2013, purchasing mills in Georgia, South Carolina, and North Carolina to diversify away from British Columbia's increasingly constrained timber supply (due to mountain pine beetle devastation, First Nations land title claims, and provincial timber harvest reductions). Interfor's geographic diversification from BC to US South reflects a broader Canadian lumber industry trend: BC's Interior timber supply is fundamentally declining due to pine beetle kill, making sustained growth dependent on US market access — which is simultaneously constrained by US softwood lumber duties.

Chokepoint2023
Interfor's US acquisition strategy from 2013 onward was driven by a structural supply crisis in British Columbia's Crown timber system. The mountain pine beetle epidemic killed an estimated 18.1 million hectares of BC Interior forest — more standing timber than exists in all of Germany's forests. BC's Annual Allowable Cut (the government-controlled maximum harvest volume) has been reduced multiple times since 2010 as beetle-killed timber became uneconomic to harvest. Combined with First Nations title claims reducing accessible harvest areas and provincial land-use decisions removing timber from the land base, BC's timber supply is on a long-term declining trajectory. The same US softwood lumber supply chain that US homebuilders depend on is thus structurally constrained by a Canadian forest ecosystem collapse driven by climate-related pine beetle expansion — a supply chain risk that housing construction cost forecasters rarely model explicitly.
Government of British Columbia ↗Origin2023
Interfor Corporation was established in 1963 in Vancouver as International Forest Products Limited, a BC Interior sawmill operator. For its first 50 years, Interfor was entirely dependent on BC Crown timber licenses — government-granted rights to harvest BC's publicly owned forests. The mountain pine beetle epidemic (which began devastating BC Interior forests in the 1990s and accelerated after 2000, ultimately killing ~50% of BC's lodgepole pine) fundamentally undermined Interfor's BC timber supply outlook. Beginning in 2013 under CEO Duncan Davies, Interfor aggressively acquired US South sawmills (Southern yellow pine) and US Pacific Northwest mills, transforming from a BC-dependent company to a geographically diversified North American producer. By 2023, US mills represented over 60% of Interfor's production capacity — a structural transformation driven entirely by BC's collapsing timber supply.
