Four additional positive cases of COVID-19 were confirmed by Williams on Sunday.

The first, a Toronto man in his 50s, did not have any recent history of travel. His brother, however, had recently travelled to Iran and tested positive for the coronavirus last week.

A woman in her 70s from Newmarket also tested positive for the virus after travelling to Egypt with another confirmed Toronto coronavirus patient.
