NORTH BAY, Ontario –GreenFirst Forest Products announced adjustments to its operating schedule in response to continued challenging market conditions in the softwood lumber sector. Given current market conditions, GreenFirst will extend its holiday curtailment at three of its four sawmills — Hearst, Kapuskasing, and Cochrane — resulting in a three-week shutdown from December 22, 2025 to January 9, 2026 “Softwood lumber markets remain under significant pressure, and extending our holiday curtailment is a prudent step to better align production with current demand,” said Joël Fournier, Chief Executive Officer of GreenFirst. …These pressures have led to curtailments across the industry as producers work to balance supply with demand. GreenFirst will continue to closely monitor market dynamics and will adjust production plans as necessary.
