Set within the determinants of health framework and drawing upon Statistics Canada's longitudinal National Population Health Survey, this paper explores the self-assessed health of Canada's immigrant population. Using both descriptive and multivariate techniques, including logistic regression and survival analysis, the intent is to identify differences in self-assessed health between the immigrant and native-born populations, the factors that contribute to immigrant self-assessed health, and the factors associated with declining self-assessed health status. In each case, the key questions are whether differences in health status exist between the native- and foreign-born. Results indicate mixed support for the Healthy Immigrant Effect, with the native- and foreign-born neither more nor less likely to rank their health as fair or poor. However, results from the proportional hazards model indicated that the native-born were at lower risk to transition to poor health.
