Critical and feminist ageing scholarship has drawn attention to how dominant discourses of ageing negatively impact older women’s identities and social lives. While research intersecting migration and ageing has broadly focused on older immigrants’ settlement experiences, very little is known about the discursive influences over older immigrant women’s sense of agency and social relations. To address this knowledge gap, this study explores the subjectivity-formations of older South Asian Muslim women engaged in transnational migration. Narrative and discourse analysis principles were used to conduct and analyse life story-based interviews with 15 South Asian Muslim older women who recently migrated to Toronto, Canada. Findings indicate that participant subjectivity-formations are shaped by: (a) discourses of ageing; (b) socio-cultural–religious discourses; and (c) discourses of transnational migration. In response, participants engaged in dynamic strategies including conforming, negotiating, creating alternative narratives and/or resisting these discourses to organise their lives. These findings reinforce the continued need to trace the governmentality of structural conditions over ageing migrant women’s lives and their responsive strategies to manage these impacts.
