This dissertation explores the role that feminist pro-choice activists have played in resisting and reshaping the social organization of abortion care in New Brunswick. Using political activist ethnography (PAE), my research demonstrates the ways in which activists may help to reveal the social relations organizing abortion access in order to ultimately transform them. Building on PAE and movement-relevant theories, I argue that movement spaces are key sites of knowledge production, and thus offer a useful starting point for research that aims to challenge and transform social relations of ruling.Contemporary research on abortion in Canada has largely centered on the unequal regional distribution of abortion services, the disproportionate impact of access barriers among marginalized women and communities, and the role of provincial governments and health authorities in allocating abortion services in the context of Canadian federalism. My dissertation extends these conversations by offering a case study into the unique access barriers imposed by the provincial government in New Brunswick, as mediated by the province's Medical Services Payment Act. Based on twenty-five in-depth semi-structured interviews, two years of participant observation with Reproductive Justice New Brunswick (RJNB), as well as archival research into the history of abortion regulation in the province, I trace how the closure of the Fredericton Morgentaler Clinic helped spark a grassroots movement to expand abortion access and repeal the province's public funding restrictions for clinic abortions.This dissertation would not have been possible without the support and care of my wonderful partner and husband, Scott Lewin.
