THUNDER BAY—  Citing plunging demand and rising costs, Thunder Bay Pulp and Paper announced Thursday it plans to end the production of newsprint, putting 150 people out of work.The company said it will file notices with the Ontario Ministry of Labour to cease newsprint operations in the first quarter of this year. “This decision was made only after significant efforts to reposition the company within the evolving and rapidly declining newsprint market were fully explored,” the company said. The impacts of declining market demand were further compounded by significant increases in input costs.This production shift and potential job loss mark another hit to Canada’s forestry sector, long targeted by the U.S. trade measures. Demand for newsprint in North America declined 18 per cent in 2025 alone. Demand decline is the most insurmountable factor in the decision to cease newsprint production in Thunder Bay.
