This webinar was intended to share results from the research project, Upstream determinants of effective COVID-19 response: learning from comparisons across Canada’s provinces, funded by CIHR, in which the NCCHPP is a collaborator. While research on global public health responses to COVID-19 has primarily focused on the virus’ epidemiology, transmission interventions, and their outcomes, there remains a significant gap in situating these findings within the institutional, political, and organizational contexts of different jurisdictions.
