Interfor Corporation plans to cut lumber production by approximately 250 million board feet in the fourth quarter of 2025, a 26% decrease from the 936 million board feet produced in the second quarter. The new figure increases the company's previously announced plan from which targeted a reduction of approximately 145 million board feet between September and December, representing a 12% decrease from normal operating levels.

The latest curtailments are evenly split between Canadian and U.S. operations and reflect the company's response to persistently weak market conditions and ongoing economic uncertainty. Interfor produced approximately 910 million board feet of lumber in the third quarter, slightly below second-quarter output.

The September plan anticipated production cuts of 12% across all operating regions in both Canada and the United States. Those temporary reductions were to be implemented through a mix of reduced operating hours, extended holiday breaks, reconfigured shifts, and prolonged maintenance shutdowns. The current update significantly increases the scale of curtailments for the fourth quarter alone.

"Lumber prices in all regions of North America have continued to weaken, from already unsustainably low levels," said Ian Fillinger, Interfor's President and CEO. He stated that the revised plans align production with demand, while acknowledging the impact on employees, contractors, suppliers, and communities.

Interfor has annual lumber production capacity of approximately 4.7 billion board feet. The company said it will continue monitoring conditions and adjust its production plans as needed.
