St. Michael's Hospital says it is unable to accept walk-in patients at its emergency room through the weekend after a burst pipe caused flooding earlier this week.

The downtown hospital can only take patients arriving by ambulance and Ornge.

The hospital encouraged those needing emergency care to call 911 or visit another nearby hospital's emergency room.

A second-floor pipe burst around 1 a.m. Tuesday, causing flooding and forcing the hospital to close its emergency room. 

Around 30 people were in the emergency department at the time. Some patients were admitted while less urgent cases were sent to other hospitals.

It partially reopened Wednesday after over 36 hours of diverting patients while repairs were underway.
