One of the critical problems facing the health system is inequitable access to health promotion, treatment and other services; especially for those facing language and other systemic barriers. A very promising innovation developed in recent years by Community Health Centres, public health and other community-based providers is the idea of peer health ambassadors. These are people from particular communities — whether a neighbourhood, cultural community, drug users or others often marginalized by mainstream services — who are trained and supported to provide services and support to their peers. These models have proven effective in helping people navigate the complex healthcare maze, in increasing access to screening and other preventative services, in well-baby care and in many other areas. These are notes from a talk we gave at the Canadian Public Health Association annual meeting.
