Ontario Public Health Emergencies Science Advisory Committee (OPHESAC)
The Ontario Public Health Emergencies Science Advisory Committee (formerly the Ontario COVID-19 Science Advisory Table) is a group of independent, multi-disciplinary experts whose role is to enhance provincial capacity to respond to a spectrum of public health emergencies with the best available evidence. OPHESAC provides independent scientific advice to PHO, and where appropriate through PHO to Ministry of Health, to inform the management of public health emergencies, including COVID-19.
Health equity is a core component of OPHESAC scientific advice, consistent with PHO’s legislated objects. Populations which may be disproportionately affected by public health emergencies will be considered and addressed in OPHESAC’s scientific advice.
OPHESAC will produce important scientific reports and recommendations to support PHO and the province in its response to COVID-19 and future public health emergencies. All OPHESAC resources will be made publicly available on this webpage. Please see the Ontario COVID-19 Science Advisory Table website for resources published by the Table prior to the implementation of OPHESAC.
