Best Times to Visit

🟢 Quieter times

Emergency departments are generally less busy during overnight hours (late night to early morning) and on weekday mornings before mid-morning. If your situation is not immediately life-threatening, these windows may mean shorter waits. Always call 911 or go directly to the ER for serious or life-threatening emergencies regardless of time.

🔴 Busier times

Emergency departments across Ontario tend to be busiest on weekday evenings (after work hours), weekend afternoons and evenings, and during cold and flu season (fall and winter). If your concern is urgent but non-life-threatening, checking real-time posted wait times before you leave can help you plan your visit.

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 using historical volumes, current patient counts, and staffing. Actual wait times may vary.
