Public health units also processed more than 34,200 tests yesterday, which is just shy of the provincial record of 40,127 tests completed on the weekend.

Health experts have been sounding the alarm for a while nowas cases have grown exponentiallyover the past 10 days or so, and many are calling for stricter government measures in order to avoid overwhelming the healthcare system with case numbers in the 1000s.

And while the provincial government did announce newstricter gathering limitsfor Ontario as a result of rising numbers this past weekend, Premier Doug Ford is expected to make another announcement related to the province's fall COVID-19 plan at his daily press briefing this afternoon.
