Jul 02, 2008. /Lesprom.com/. Management of Norampac, a division of Cascades Canada Inc. announces the closure of its Toronto boxboard mill for an indefinite period of time, due to unfavourable factors. Nearly 140 employees will be affected by this closure, which will be effective at the latest on September 14, 2008. The Toronto mill has an annual production capacity of coated recycled boxboard (CRB) of approximately 180 thousand short tons. During the shutdown period, Norampac's East Angus (Quebec), Jonquiere (Jonquiere) and Versailles mills will ensure the supply of CRB to customers. "This decision was taken to mitigate the negative impacts of several factors such as high labour costs, growing fibre supply costs and rising energy costs. Unfortunately, we do not have any other choice at this point than to suspend the mill's operations," stated Marc-Andre Depin, President and CEO of Norampac. Norampac owns 7 containerboard mills, 4 boxboard mills, 27 corrugated products plants and 5 folding carton plants in the United States, Canada and France. Norampac is the largest containerboard producer in Canada and the third largest boxboard producer in North America. Norampac, which is also a major Canadian manufacturer of corrugated products and folding cartons, is a division of Cascades Canada Inc.
