COVID-19 Rapid Evidence Service


The National Collaborating Centre for Methods and Tools’ (NCCMT) Rapid Evidence Service supports the public health sector’s response to the COVID-19 pandemic. The Service answers priority COVID-19 questions from public health professionals with rapid reviews.

The NCCMT has answered questions from the Pan-Canadian Public Health Network’s Special Advisory Committee and Technical Advisory Committee on COVID-19 and the Public Health Agency of Canada (PHAC). We have also supported other organizations at international, federal, provincial, territorial and local levels.

The Rapid Evidence Service team applies an internationally accepted rapid review methodology. The team begins by conducting a comprehensive search to find relevant evidence. Two raters then independently appraise the evidence for methodological quality and weigh the findings by quality. Finally, the team synthesizes the findings in plain language.

Priority topics are updated as capacity allows.
