The closure will start at 5 p.m. on Sunday.

The health authority says that patients who arrive at the emergency department before that time will be seen by a physician by the end of their shift at 11 p.m.

The temporary closure is due to physician staffing challenges.

“During the service interruption, emergency-trained nurses will continue to be on site and available to support walk-in patients needing basic care, assist with re-direction of care, and/or transfer patients with urgent needs to a neighbouring hospital,” Fraser Health said in a written statement.

It advises people experiencing a life-threatening emergency to call 911.

Those patients “will be transported to the nearest available and appropriate facility.”

All other services at Mission Memorial Hospital remain available during the ER closure.

Earlier this month, the emergency department was operating on reduced hours, only accepting patients between 8 a.m. and 5 p.m.
