Markham Stouffville Hospital Emergency Room

The Emergency Department at Markham Stouffville Hospital is an operational, hospital-based emergency room located at 381 Church St in Markham, Ontario, serving patients across the surrounding York Region communities. Whether you are dealing with a sudden illness, an unexpected injury, or a medical situation that cannot wait for a scheduled appointment, the emergency department is equipped to provide urgent and acute care around the clock.

When you arrive, your care begins with a triage assessment. A nurse evaluates your condition so that patients with the most serious or life-threatening needs are seen first. This process is standard across Canadian emergency departments and helps ensure that critical cases receive immediate attention. Wait times can vary depending on the volume of patients and the severity of cases being treated at any given time.

The department handles a wide range of urgent medical concerns, including chest pain, difficulty breathing, severe infections, head injuries, fractures, abdominal pain, and other conditions requiring prompt evaluation and treatment. Additional services are available on-site to support emergency care, which may include diagnostic imaging, laboratory testing, and specialist consultations depending on your needs.

Parking is available at the hospital for patients and visitors coming to the emergency department. If you are being discharged, the care team will walk you through follow-up instructions and next steps before you leave. For patients who have recently had surgery and are experiencing complications, the hospital provides guidance on where to direct those specific concerns.

Markham Stouffville Hospital is part of Oak Valley Health, a regional health network serving communities in and around Markham, Stouffville, and Uxbridge. The Church Street location is easily accessible for residents in Markham's central and east-end neighborhoods, as well as those coming from nearby areas in Durham and York Region.

If you are facing a medical emergency, call 911 or go directly to the emergency department. For non-urgent health concerns, a walk-in clinic or your family doctor may be a more appropriate first step. The emergency department is best suited for situations that are sudden, serious, or potentially life-threatening, and the care team there is prepared to support patients through those moments.
