Starting Thursday, the Tofield Health Centre will close its emergency department overnight because of staffing shortages.
The department will close from 8 p.m. to 8 a.m., seven days a week.
Patients will be referred to emergency departments in surrounding communities, and ambulances will be diverted to Camrose or Viking for emergency care.
While AHS said the closure will be temporary, a reopening date has not been announced.
Residents are reminded to call Health Link 811, which is available 24 hours a day, seven days a week for health questions.
Patients should call 911 in a medical emergency.
Tofield is about 70 kilometres east of Edmonton.
