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.
