Pre-hospital emergency medical services and emergency ambulance transport, like all other health care in Canada, is the responsibility of the provincial government. The City of Winnipeg operates the WEMS as a "service purchase agreement" to provide these services for the Winnipeg Regional Health Authority (WRHA) and Shared Health. WEMS is also responsible for providing interfacility patient transport for patients requiring specialty services not offered at the hospital at which they are being treated and repatriate patients to community hospitals. They are assisted by the WRHA Transport Team: Respiratory Therapists with specialized training for transporting ventilated patients or those receiving certain medication infusions. All stable patients not requiring interventions, advanced skills or being repatriated to a Personal Care Home are not transported by WEMS but by Stretcher Service of Manitoba who operate under contract. WEMS also transports patients coming to the city via air ambulance to hospital.
