The Chatham-Kent Health Alliance (CKHA) telephone system will be down for maintenance on Monday, August 20 at 10 p.m.
The system plans to be back in use by 3 a.m.
Hospital officials say this will affect both sites in Chatham and Wallaceburg.
“If patient families need to reach a loved one, we ask that they make arrangements with the department the patient is in prior to the downtime occurring,” CKHA officials say.
“Thank you for your patience and understanding.”
