COVID-19 Immunity Task Force

Launched by the Government of Canada in late April 2020, the COVID-19 Immunity Task Force (CITF) has the mandate to determine the extent of SARS-CoV-2 infection in Canada (in the general population as well as in specific communities and high-risk populations) and understand the nature of immunity following infection. Its goal is to support, harmonize and rapidly implement research studies, ensuring the right studies are done quickly – to inform federal, provincial, and territorial decision-makers as they manage the COVID-19 pandemic.

The Task Force Leadership Group includes leading Canadian scientists and experts from universities and hospitals across the country. It works closely with federal, provincial and territorial public health officials, as well as researchers, implementing partners, communities and stakeholders in order to best serve all Canadians.

The Task Force’s Secretariat is housed at McGill University’s School of Population and Global Health and is led by SPGH’s Director, Dr. Timothy Evans. One of the Task Force’s two co-chairs, Dr. Catherine Hankins, is a Professor of Public and Population Health, in the Department of Epidemiology and Biostatistics at McGill University. The Secretariat is charged with developing and implementing the Task Force’s scientific strategy and ensuring research results are synthesized and disseminated to government stakeholders and to Canadians. The Secretariat welcomes staff from McGill University and beyond. To learn more about the CITF, visit
