This paper is concerned with the impact of medical inadmissibility provisions in Canada’s immigration law on applicants with disabilities. The paper draws on key informant interviews, policy analysis, and Ministry of Immigration data on medical inadmissibility findings. We follow the lead of recent mobilities scholarship to examine how the immigration system is enacted, reproduced, and contested over time. From this perspective, we see that recent court challenges to the statutory provisions have created additional procedural space for applicants to contest findings of inadmissibility. However, the legitimacy of excessive demand as a basis for exclusion remains firmly in place, while recent immigration policy changes signal an intensification of measures to limit the social reproductive costs of immigration.
