MONTREAL, Quebec – Domtar announced a curtailment in its lumber production. Due to challenging market conditions, US tariffs, and ongoing economic uncertainty, the company will temporarily reduce its lumber production by 150 million board feet for the first quarter of 2026 across its facilities in Quebec, Ontario and the United States. “The demand for lumber in North America remains weak, requiring us to adjust our production levels in line with market conditions,” said Luc Thériault, CEO, Wood Products, and President – Canada, for Domtar. “While this decision is necessary, we are fully aware of the impact it will have on our employees, contractors, suppliers and the communities in which we operate.” Domtar will continue to monitor market conditions and adjust its production plans accordingly. Domtar has a workforce of nearly 14,000 employees in more than 60 locations across North America.
