The document discusses primary health care (PHC) and its importance in the Canadian health system. It outlines the key principles of PHC, including accessibility, public participation, health promotion, appropriate technology, and intersectoral cooperation. While primary care focuses on clinical services and treatment, PHC takes a more holistic approach to consider various social and environmental factors that influence health. The Canadian Nurses Association has advocated for a health system based on PHC and involved nurses in various initiatives to better integrate PHC in practice.
