Wait time data for Hamilton is sourced from individual hospital websites and updates as frequently as every 15–30 minutes. ERstat displays the estimated time from triage registration to being seen by a physician.
All emergency departments in Hamilton use the Canadian Triage and Acuity Scale (CTAS) to prioritize patients. Patients with more serious conditions are always seen first, regardless of arrival time or displayed wait. A shorter posted wait does not guarantee a shorter visit — it depends on the severity of your condition relative to other patients in the department.
Check wait times on this page before leaving. ERstat updates every 5 minutes and shows all Hamilton ERs sorted from shortest to longest wait. Each hospital page includes a 12-hour forecast chart and a “Best Time to Visit” pattern based on historical data.
If your condition is not life-threatening, consider whether a walk-in clinic, urgent care centre, or pharmacist could help instead. Ontario pharmacists can assess and prescribe for many common conditions with no appointment needed. See what your pharmacist can treat →
