Thunder Bay Pulp and Paper will permanently cease its newsprint mill operations in Thunder Bay in the Q1 2026, citing an insurmountable decline in market demand. The company will file closure notices with the Ontario Ministry of Labour, a decision that will directly impact up to 150 employees, according to Thunder Bay Pulp and Paper.
The company attributed the closure to a 40% decline in North American newsprint demand since 2022 and an 18% drop in 2025 alone, compounded by significant increases in input costs. It will continue operating its single-line Softwood Kraft pulp mill, which supports an estimated 7,000 jobs in the regional supply chain. The paper machine will be shut down in a condition that allows for potential future conversion.
The company stated it is working with unions and government bodies to provide transition supports and retraining for affected workers. It also plans to pursue new investment in the Softwood Kraft pulp mill with federal and provincial government support.
