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.
Notice: Weapons Detection Pilot at Oshawa Hospital
From July 9 to 23, 2025, Lakeridge Health will be piloting a weapons detection system at the Emergency Department entrance at the Oshawa Hospital. This short-term demonstration is part of our ongoing efforts to maintain a safe and respectful environment for patients, visitors, and staff.
About the Demonstration
During this demonstration, we will test the Xtract One SmartGateway, a weapons detection system designed specifically for high-traffic environments like hospitals. Unlike traditional metal detectors, this technology uses advanced sensors and artificial intelligence to detect potential weapons without the need for people to empty their pockets or bags.
Here’s what you can expect:
-
Fast and respectful screening – No need to remove phones, keys, water bottles, or other personal items.
-
Mobility-friendly – The system accommodates mobility devices and assistive equipment.
-
Privacy-focused – No personal or facial recognition data is collected.
-
Inclusive options – Alternative screening paths will be available for individuals with medical devices, mobility concerns, or other needs.
Spiritual and cultural practices will continue to be respected during this pilot.
We appreciate your cooperation as we continue to build a safer health-care environment.
