TORONTO -- Ontario has reached a grim milestone as the province reports the highest daily COVID-19 case count since the beginning of the pandemic.

Health officials reported 700 new infections on Monday, breaking the previous high of 624 cases on April 24.

One COVID-19-related death was recorded in the last 24-hour period and 331 cases of the disease are now considered to be resolved by the province.

Monday’s report brings the total number of infections in Ontario to 50,531, including 2,840 deaths and 43,127 recoveries.

Nearly half (317) of the new cases reported Monday are in people between the ages of 20 and 39. That age group accounts for most of Ontario’s lab-confirmed COVID-19 cases at 17,317.

183 cases were recorded in people between the ages of 40 and 59, while 101 new infections were reported in people 19 years of age and younger.

Eighty-seven new cases are in people between the ages of 60 and 79 and 15 new cases were documented in people 80 years of age and older.
