Machine number 7 will run for two to three months beginning July 17.
CEP National Rep Stephen Boon says about 40 people, laid off earlier this year, will be asked to return.
He says the return will be voluntary and former workers who refuse won't be in fear of losing their severance or recall rights.
Boon says many workers who might be called back may have found new jobs and won't be able to return.
Boon says they are still hoping for some feedback from Resolute on what the long range plans are for the mill.
