Montréal, Quebec – Domtar Wood Products announced today a curtailment in its lumber production. Due to challenging market conditions and ongoing economic uncertainty, Domtar will temporarily reduce its lumber production by 100 million board feet for the fourth quarter of 2025, including additional curtailments for the holiday season, at its facilities in Quebec, Ontario, and the United States. “Demand for lumber continues to stagnate in North America, exacerbating an already difficult market,” said Luc Thériault, President of Domtar Wood Products. Domtar will continue to monitor market conditions and adjust its production plans accordingly. [END]
