Interfor Corporation will reduce lumber production by approximately 145 million board feet between September and December 2025, representing approximately 12% of its normal operating stance. The company has annual lumber production capacity of approximately 4.7 billion board feet.

The temporary curtailments will be through a combination of reduced operating hours, prolonged holiday breaks, reconfigured shifting schedules and extended maintenance shut-downs. The curtailments are expected to impact all of Interfor's operating regions, with both the Canadian and U.S. operations expected to reduce their production levels by approximately 12% each.

The curtailments are in response to persistently weak market conditions and ongoing economic uncertainty. Interfor said it will continue to monitor market conditions across all of its operations and adjust its production plans accordingly.
