Interfor Corp. plans to permanently close its Hammond sawmill in Maple Ridge, B.C., affecting more than 100 workers. The Vancouver-based company says the closure is part of a reorganization of its forestry and woodlands operations amid tight supplies of logs for processing. It says the shutdown will be complete by the end of 2019, after the mill’s remaining log and lumber inventories have been processed and shipped. Interfor chief executive Duncan Davies says the company, which has 18 mills across North America, will seek jobs for the affected workers at its other operations or at outside mills.
