Jüni is originally from Switzerland and will work in Oxford, England to be closer to his family.
He has been in charge of the Ontario COVID-19 Science Advisory Table since its inception in the summer of 2020.
“He has accepted a new position in Oxford UK that commences July 1,” a spokesperson for Jüni told Global News.
The doctor also works at St. Michael’s Hospital in Toronto and at the University of Toronto, where he is a professor of medicine and epidemiology.
During the third wave of the COVID-19 pandemic, Jüni admitted he considered stepping down over the government’s handling of the situation.
“It really pains me. I was desperate. I see something that is perfectly avoidable happening anyway and it’s absolutely unclear to me why,” he said last year.
A spokesperson said Jüni is stepping down “to be closer to family in Europe” and not for any reason relating to policy.
