Over twenty years ago, Correctional Services Canada launched the Mother Child Program (MCP) to mitigate harms of separating incarcerated mothers from their babies. It has never been subjected to internal evaluation or independent study. The aim of the qualitative study was to explore the experiences of advocates employed by Elizabeth Fry Societies (EFS), community organizations dedicated to the support of incarcerated women, with respect to supporting people who were pregnant or had young children while federally incarcerated and did or did not participate in the MCP.
