COVID-19 Health Research Priorities Framework

Purpose of the Framework:

The COVID-19 Health Research Priorities Framework (Framework) provides guidance on the key research priorities needed to support Ontario’s COVID-19 response.

The Framework elevates to the forefront topics where evidence and research are needed to inform policy and planning, and to create a better, faster, and more efficient response to COVID-19 in order to protect the health of Ontarians. It also considers where Ontario has a particular strength in, or need for, this type of research and where results can be generated in the short-term (<2yrs) to support Ontario’s COVID-19 response.

The Framework will continue to evolve over time and be refined as new information, gaps and priorities emerge.

This tool can be used to:

  • Identify research/evidence projects of particular relevance for provincial funding;
  • Map existing provincial/federal funding projects against MOH priorities to identify gaps in evidence needs; opportunities for collaboration, rapid learning and duplication of effort;
  • Communicate ministry key priorities for research and consult key stakeholders on priority evidence needs;
  • Inform how other research across Ontario aligns to the research priorities of the Ministry of Health;
  • Understand how current research could support Ontario’s data infrastructure needs and inform internal ministry round tables, such as those related to the COVID-19 Health Data Platform; and
  • Inform pandemic research and partnerships with external ministry initiatives, such as the Ontario SPOR (Strategy for Patient-Oriented Research) SUPPORT Unit; and, opportunities to partner on new federal research calls for COVID-19 related research, such as CIHR’s research calls.

How it was developed:

The Framework reflects collective input over time from the Ministry of Health, Ontario Health, Public Health Ontario and the COVID-19 tables.
