Best Times to Visit

Quieter times: No historical wait time data is available for this location. Generally, emergency departments in Ontario tend to be less busy on weekday mornings (8am–11am) and early afternoons. If your situation is not life-threatening, consider whether a walk-in clinic or virtual care option may be appropriate before visiting the ED.

Busier times: Without specific wait time data, general patterns suggest evenings (5pm–10pm), weekends, and holidays typically see higher ED volumes at community hospitals. As a popular ambulance redirect destination from east-end Toronto hospitals, MSH may experience higher-than-average volumes during regional surge periods.

About ER Wait Times

Emergency departments use triage. Patients with more serious conditions are seen first, regardless of arrival time.

Wait times are estimates based on Ontario health data. Actual wait times may vary.

This hospital does not publish a live wait, so the figure above comes from our model rather than from its own feed. We publish how that model performs where it can be checked, at the hospitals that do publish. See the accuracy scorecard, or how we work the number out.

If you are experiencing a medical emergency, call 911 immediately.
