The emergency room at the New Waterford Hospital will be closed on Tuesday, August 16.
It will reopen on the next day, Wednesday, August 17, at 7 a.m.
The Nova Scotia Health Authority says the closure is due to a lack of physicians to cover the shift.
They also say New Waterford-area residents who need emergency service should call 911 or go to the emergency room at the Cape Breton Regional Hospital in Sydney.
If you have a non-urgent health matter, call 811 to speak to a registered nurse.
