Non-emergency options
Quieter times: Southlake's ED serves over 120,000 patients annually, so some wait times are unavoidable. Generally, early morning hours on weekdays (before 9 a.m.) tend to be quieter. If your condition allows flexibility, mid-morning on a weekday is often a better time to visit than evenings or weekends.
Busier times: Emergency departments across Canada, including Southlake's, are typically busiest on Monday mornings, Friday evenings, and throughout the weekend, as well as during evenings after walk-in clinics close (usually after 8 p.m.). Avoid these peak times if your condition is non-urgent.
