Provincial health officials say if nothing changes, we'll be seeing 1,000 cases of the virus a day, in early October.
New modelling data released today, shows the number of new cases is doubling every 10-12 days.
If the number of cases continues to grow, Ontario could see between 200 and 300 patients with COVID-19, in ICU every day.
The second wave started with younger people getting sick, but that's now expanding to those who are over the age of 40.
However, despite the increases, health officials say they have no intention of limiting non-emergency surgeries, and there's no intention yet to close down schools.
