Ontario predicts daily counts of COVID-19 could hit 1,000 new cases by the first half of October.
The stark new forecasting comes in updated modelling released today by the provincial government.
The projections say the province has seen an upward trajectory in COVID-19 in recent weeks, with cases currently doubling every 10 to 12 days.
Officials say the modelling doesn't take into account new rules introduced by the government in recent days, such as closing strip clubs and limiting hours of operation for bars and restaurants.
The modelling also warns about the risks of increasing occupancy in hospital intensive care units.
Normal hospital operations cannot be maintained if more than 350 patients are in ICUs across the province.
