Dr. Alix Carter of Emergency Health Services says the changes will help people stay at home rather than go into emergency rooms when they're experiencing pain.
Carter says paramedics will be trained to provide the palliative support a patient wants.
Otherwise, patients are often taken by ambulance to hospital.
The 1,400 ground-ambulance paramedics in the provinces will be able to manage such symptoms as pain, breathlessness, fear and anxiety.
The project will start in early May.
