St. John Ambulance is Canada's leading authority in First Aid since 1883. The mission of St. John Ambulance is to enable Canadians to improve their health, safety and quality of life by providing training and community service. As a charitable, humanitarian organization profits from first aid courses and product sales are reinvested into our volunteer community service programs such as medical first response, disaster response, search & rescue, car seat clinics, health and safety related youth & adult programs and therapy dog services.t John Ambulance
