Drawing on the concept of policy feedback, this paper examines how people's experiences with the health care system affect their sense of political agency and their propensity to participate in political and civic life. The data are taken from a survey conducted in Canada's most diverse and populous province. The survey queried respondents about a variety of political and civic activities, as well as their health status and experiences when accessing care in public hospitals, medical clinics and doctors' offices. The sample included a large over-sample of low-income respondents.
