The COVID-19 crisis has tested principles of universal health-care like never before. Even in nations with publicly-insured healthcare, access is formally and practically conditional on citizenship and immigration status. The COVID-19 crisis has prompted a small set of national and sub-national governments to temporarily waive citizenship-based restrictions, either through changes directly to health care policies, or laterally through the issuance of temporary designated status for non-status and precarious status migrants. This paper examines changes to health care policies in the provinces of Ontario and Québec, which effectively bypass tightening immigration policies at the federal level. It focuses on barriers to implementation, which include lack of clarity in provincial policy, inconsistent practices on the front-line, collateral effects of exclusion from social assistance, and the sharing of health information with border officials.
