The Chesley emergency department will be closed Monday because of staffing shortages.
It will re-open Tuesday morning at 7 a.m.
The South Bruce Grey Health Centre said ambulance by-pass has been undertaken and patients will be diverted to the closest emergency department.
"Anyone requiring immediate medical attention should call 911to be taken to the nearest emergency department," the media release said.
SBGHC is also advising patients with non- urgent health care needs that Health Connect Ontario is available 24/7 for non- emergency health care needs.
