Norampac Inc. has announced that it will permanently close one of two paper machines at its linerboard mill in Red Rock, Ontario, throwing 125 to 175 people out of work. The company blames the stronger Canadian dollar and an increase in energy and wood fibre costs in Northern Ontario for the closure at the 60-year-old mill. The machine that will close was used to manufacture some 150,000 tonnes a year of kraft linerboard, or brown paper. No decision has yet been made about the mill’s second, 300,000-tonne paper machine. The northern Ontario mill employs a total of 435 people. Norampac is a joint venture of Domtar Inc. and Cascades Inc.
