Emergency Preparedness

At Michael Garron Hospital (MGH), protecting the health and safety of our patients and care partners, staff, physicians, students and volunteers is our top priority. We do this in many ways including preparing for possible emergencies that could occur at the hospital. 

Emergency Codes at Michael Garron Hospital  

MGH uses an emergency code system to notify necessary individuals of a potential or active emergency. This code system is standardized across the province of Ontario and uses different colours to signify various emergency situations. All MGH staff, physicians and volunteers understand what each code refers to and know how to respond accordingly. 

During your time at MGH, you may hear overhead announcements declaring an emergency code or see staff responding to an emergency. During any emergency situation, it is important to remain calm and follow all instructions provided by staff.  

Below, you will find a list of all the emergency codes you may hear while at the hospital, along with instructions about what to do if they are called during your visit. 

Please note: The purpose of the following list is to provide information for patients, families and care partners who wish to learn about emergency codes at MGH. We understand that this information may cause feelings of fear or nervousness. If you wish to learn more about Emergency Preparedness at MGH but do not wish to read this page, please email @email to speak to a member of our team. 

Quick tip:  If you see an emergency at MGH, please inform the nearest staff member or volunteer.
