A paramedic is a healthcare professional trained to provide emergency medical care, typically working in ambulance services responding to 911 calls. Paramedics assess patients, provide life-saving interventions, administer medications, and transport people to hospitals. Different paramedic levels (Primary Care, Advanced Care, Critical Care) have varying training and capabilities. In many provinces, municipalities operate land ambulance services with paramedics as employees, while some provinces have provincial services. Paramedics increasingly provide community paramedicine, visiting patients at home to reduce emergency room visits. The role has expanded beyond emergency response to include non-emergency medical transportation and preventive care programs.
