One Society Network


The One Society Network was funded by the Public Health Agency of Canada (PHAC) and the Natural Sciences and Engineering Research Council of Canada (NSERC) under their Emerging Infectious Disease Modeling (EIDM) Initiative ( ).


The Network connected researchers across Canada, working to understand the broad impacts of infectious diseases, like COVID-19, and related public health policies.   It operated between 2021 and 2024. It is one of five (5) new, interconnected research networks announced by PHAC and NSERC on April 9th, 2021, in order to build Canada’s capacity to understand and manage pandemic threats, inform public health measures and complement PHAC’s existing modelling initiatives, by allowing for vital information sharing in a timely manner. 

While other networks focus on building Canada’s epidemiological modeling capacity, the One Society Network complements their efforts by providing connections with leading academic researchers in other sectors, including those specializing in economics, education, the environment, Indigenous populations, marginalized communities, and other areas of health.

Leadership: The Network was led by Vic Adamowitz, Ph.D. (University of Alberta) and Chris Cotton, Ph.D. (John Deutsch Institute for the Study of Economic Policy, Queen’s University), and Chris McCabe, Ph.D, former CEO of the Institute of Health Economics and managed by Ellen Rafferty, Ph.D. (Institute of Health Economics). The Network grew out of previous cross-sectoral collaborations among network members to assess COVID-19 policy, including the Royal Society of Canada’s COVID-19 working group on economic recovery, Global Canada’s COVID Strategic Choices Group, and Canada’s Digital Technology Supercluster Looking Glass project.

Scientific committee and partners: The One Society Network brings together researchers with expertise in health, macroeconomics, the environment, education, agriculture, transportation, marginalized communities and labour markets, as well as epidemiologists, mathematicians and health policy experts from universities and organizations across the country. Our core team includes researchers from: Institute of Health Economics; Queen’s University; University of Victoria; Simon Fraser University;University of Alberta; Alberta Health Services;University of Saskatchewan; University of Manitoba; York University; University of Ottawa; Limestone Analytics

The three (3) main goals of the One Society Network were:

  1. To develop methods and modelling products to allow for the comprehensive evaluation of alternative policy responses during pandemics for all sectors of the economy and all aspects of society, including marginalized groups. This will be achieved  by capturing the dynamic feedback loops between policies, individual behaviours, social and economic impacts and the long-term effectiveness of those policies.
  2. To create multi-disciplinary training programmes in collaboration with mathematical modelers, epidemiologists, health economic modelers, and micro and macro-economic modelers. These training programmes will support the development of a cohort of Highly Qualified Personnel who can provide One Society analyses to support public policy making in future pandemics.
  3. To establish a One Society community of practice that shares knowledge, methods and outcomes across disciplines, enhancing Canada’s ability to respond to future pandemics by building capacity in interdisciplinary research.
