This article describes the emergence of imprisonment as part of the collection of child-support debt in Alberta, Canada. This approach to child poverty arose in the context of political conservatism, a shift in the feminist movement, and changes in the legal environment. Findings indicate that incarceration for support debt is increasing and that Blacks, Aboriginals, the unemployed, and those without post-secondary education are over-represented among those imprisoned for support debt. It is argued that child-support enforcement as an implement of social policy has limits, especially among low-income payors.
