One of the province's top doctors is warning that the list of Ontario's essential workers needs to be limited to help stop the spread of COVID-19.

In a press conference on Thursday, Dr. Adalsteinn Brown, co-chair of the Ontario COVID-19 Science Advisory Table, stated that while the mobility of retail and transit has dropped, workplace mobility remains high.

"Workplace mobility is too high. Limiting essential workplaces and keeping sick workers at home will help control cases," Brown said.

A graph showing how COVID-19 cases will look in the next few months, predicts Ontario will only see cases dip under 2,000 a day if best-case assumptions are followed.

This means that creating a shorter list of essential workplaces, lowering mobility and having effective sick days needs to be put in place.
