In Canada, links between social determinants and household food insecurity (HFI) are well-documented, but the influence of political parties remains unclear. This study examines whether political parties predict HFI rates across Canadian provinces and explores the mediating roles of low income and social assistance. Panel data from 2005 to 2014 were obtained from Statistics Canada, with political party strength categorized as left, center, or right. Linear regressions with Driscoll and Kraay standard errors reveal that left-leaning parties are associated with lower HFI rates, right-leaning parties with higher rates, and center parties show no significant effect, controlling for demographic and economic factors. Low income and social assistance fully mediate the effect of left parties but only partially mediate the effect of right parties. These findings provide insights into the politics of food insecurity, with implications for social work in the context of COVID-19.
