NOVA SCOTIA — The Northern Pulp mill, which has been under creditor protection after it shut down more than four years ago, is seeking its second extension on a stay of proceedings this year. Northern Pulp announced it filed documents requesting the extension under the Companies’ Creditors Arrangement until July 18. The company had previously requested an extension until early May, which Minister of Natural Resources Tory Rushton said the provincial government would approve. “The company will use this time to further advance preparations for a potential sale of its assets, should a new mill not be feasible,” the company said. “Additionally, Northern Pulp will continue discussions with various stakeholders and rights holders regarding the feasibility of establishing a new bioproducts hub in Liverpool, Nova Scotia.” The company previously said designing and building the bioproducts hub could cost more than $2.5 billion. …The hearing for the extension request is scheduled for Friday.
