TORONTO -- Ontario health officials recorded more than 1,500 new infections in the province on Saturday, marking a new record in the daily-reported number of infections in the province.

Health officials confirmed 1,588 new cases of the novel coronavirus on Saturday. For the past week, the province logged numbers below the 1,500 mark. Most recently, the province added 1,418 new cases on Friday and 1,210 new cases on Thursday.

This is the 16th straight day in which Ontario has reported case counts in the quadruple digits.

Saturday’s single-day rise in new infections marks a new record for the province, surpassing last Saturday’s record-breaking number of 1,581 cases.

The province also reported that 21 more people have died due to COVID-19, marking an uptick in the number of deaths from the day before when health officials reported eight new deaths.

Seniors continue to be the age group hardest hit by the pandemic. According to the province’s epidemiology report, 13 of the 21 deaths recorded on Saturday were long-term care home residents.

Since the pandemic started, of the 3,472 people who have died in Ontario due to the disease, 2,409 were over the age of 80.

Provincial health officials deemed 1,363 more cases to be resolved as of Saturday, bringing the total number of recovered patients in Ontario to 86,079.

The total number of lab-confirmed cases of COVID-19 in Ontario now stands at 102,378, including the 3,472 deaths and the 86,079 recoveries.

There are at least 513 people currently in Ontario hospitals due to COVID-19, and 146 of those patients are in an intensive care unit. Eighty-seven of them are breathing with the assistance of a ventilator.

Last week, CTV News Toronto obtained a report by Critical Care Services Ontario that confirmed there were 150 patients in the province’s ICUs due to the novel coronavirus.

The province previously stated that once the number of COVID-19 patients in the ICU reaches 150, it becomes harder to support medical needs not related to the disease. Furthermore, once 350 COVID-19 patients are in the ICU in the province, it becomes “impossible” to handle other medical needs.

On Saturday, Peel Region reported 522 new cases, Toronto reported 450 new cases and York Region reported 153.

Most of the new cases of COVID-19 reported on Saturday involve people under the age of 80.
