Ontario’s reported the largest single day rise in COVID-19 cases since the start of the pandemic on Sunday, according to the Star’s count of public tallies and press releases posted by the province’s 34 regional health units.

As of 9 p.m., with several health units still to post their daily updates, Sunday had seen more than 450 new confirmed or probable cases reported, representing a day-over-day rise of 11.3 per cent.

The regional units have reported a total of 144 deaths among 4,538 cases.

Many of those came after Toronto announced its own largest one-day increase of 206 new cases. The city has so far reported 1,438 confirmed or probable COVID-19 cases, including 27 deaths, with 140 people hospitalized, and 58 in intensive care.

In its daily report Sunday morning, the province reported that a total of 1,449 patients have recovered after being infected with COVID-19.

The province says its data is accurate to 4 p.m. the previous day. The province also cautions its latest count of deaths — 119 — may be incomplete or out of date due to delays in its reporting system.

The local health units post new information to their websites throughout the day. The Star’s count includes some patients reported as “probable” COVID-19 cases, meaning they have symptoms and contacts or travel history that indicate they very likely have the disease, but have not yet received a positive lab test.
