The COVID-19 pandemic has highlighted the many challenges that provincial health systems have experienced while scaling health services to protect Canadians from viral transmission and support care for those who get infected . Supply chain capacity makes it possible for health systems to deliver care and implement public health initiatives safely . In this paper, we present emerging findings from a national research study that documents the key features of the fragility of the health supply chain evident across the seven Canadian provinces . Results suggest that the fragility of the health supply chain contributes to substantive challenges across health systems, thus limiting or precluding proactive and comprehensive responses to pandemic management . These findings inform strategies to strengthen supply chain capacity and performance in order to enable health systems to effectively respond to pandemic events.
