The Emergency Departments at our Markham and Uxbridge sites provide treatment for people in our community who experience sudden illness or trauma. Our Emergency Departments are open 24/7. They are staffed by emergency medicine experts with access to state-of-the-art diagnostic assessment equipment and laboratory services. 

We are excited to be working with The Hospital for Sick Children (SickKids), Children’s Hospital of Eastern Ontario and Holland Bloorview Kids Rehabilitation Program as the first community member of Kids Health Alliance (KHA). This great partnership brings together some of the best resources for providing care to children and youth. The KHA will focus on the Emergency Department, inpatient paediatrics and the Neonatal Intensive Care Unit (NICU).

Coming to the Emergency Department 

Bring a list or samples of all your medications. In addition, let us know if you have any allergies. Many pharmacies will now prepare individualized information charts for you.

To ensure timely, quality care for the most serious conditions, we will triage you to determine the nature and severity of your condition. There are five triage levels with 1 being the most critical to 5 being non-urgent. Patients are seen in the order of their triage level, not based on their time of arrival. If your condition changes while you are waiting to see a doctor, let the nurse know immediately. 

Our Emergency Department at Markham Stouffville Hospital is divided into zones depending on the severity of health issues. These are called the green, yellow, orange and blue/red zones.

During your visit, you will be seen by a physician or nurse practitioner or physician assistant as well as a nurse. After initial assessment and treatment, you may be admitted to the hospital, transferred to a specialty hospital or discharged home.
