Emergency Department

Lakeridge Health's Emergency Departments provide 24-hour access to care for people experiencing trauma or sudden illness. We have Emergency Departments at our Ajax Pickering, Bowmanville, Oshawa, and Port Perry hospitals.

When you arrive in the Emergency Department, you will visit the Triage Nurse who will assess your problem. Please be prepared with your health card, a list of medications and allergies, and emergency contact information.
