Interfor announced plans to temporarily curtail its lumber production by approximately 145 million board feet between September and December 2025.

The reduction represents about 12% of its normal operating capacity.

The curtailments will apply to all of Interfor’s Canadian and U.S. operations, each expected to reduce output by roughly 12%. Measures include fewer operating hours, extended holiday breaks, reconfigured shift schedules, and longer maintenance shutdowns.

The company said the move comes in response to persistently weak market conditions and ongoing economic uncertainty. Interfor noted it will continue to monitor market trends and adjust production as needed.

With an annual capacity of about 4.7 billion board feet, Interfor is among North America’s largest lumber producers, supplying a broad range of products to customers worldwide.
