Postmedia has entered an agreement to purchase SaltWire, Atlantic Canada's largest newspaper chain, according to a news release issued Friday.

SaltWire has been under creditor protection since March. It publishes more than 20 papers in Atlantic Canada, including The Chronicle Herald in Halifax, The Guardian in Charlottetown, and The Telegram in St. John's, along with associated websites.

In the release, the Canadian news media company said the potential acquisition aligns with Postmedia's commitment to preserving local journalism and supporting communities.

"If the transaction can be completed, Postmedia intends to provide the necessary back office resources and operational infrastructure to ensure there continues to be reliable and high-quality local news provided to the affected communities," said Postmedia president and CEO Andrew MacLeod.
