Emergency Rooms in Mississauga

Mississauga has 2 emergency departments — 2 open 24 hours a day, 7 days a week. 2 of 2 currently have live wait time data. Right now, 94 people are waiting across Mississauga emergency departments.

Wait time data for Mississauga 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 Mississauga 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.
