KINGSEY FALLS, Que. (News release) -- Cascades Inc. is closing three facilities as part of changes to its containerboard operations that will affect 310 employees.

The paper and packaging company says its corrugated medium mill in Trenton, Ont., that is currently idled will not restart operations, while converting plants in Belleville, Ont., and Newtown, Conn., will close by May 31.

It says it decided to close the facilities due to a combination of market conditions, higher operating costs, aging technology and the need for significant capital investment.

Cascades will work with the impacted employees to mitigate, where possible, the effect of the closures.

Employees who cannot or do not wish to relocate to other plants will receive support in their search for other employment, the company says.

Cascades will record $61 million in impairment and environmental obligation charges associated with the closures in the fourth quarter of its 2023 financial results as well as about $35 million in additional restructuring charges in the coming years.

"I would like to assure our customers that we will work with them to ensure a smooth transition," said Charles Malo, President and Chief Operating Officer of Cascades Containerboard Packaging. "I would also like to sincerely thank the Cascaders affected by this announcement. We will stand by them through this process, and we will assist in the relocation of those employees wishing to continue working for Cascades at one of our other locations."
