Ontario reported 1,023 new cases of COVID-19 on Monday, a slight drop from 1,062 cases recorded the previous day.
Another six people have died due to the virus, bringing the provincial death toll to 6,986.
It is the sixth day in a row that cases have topped 1,000.
Health Minister Christine Elliott said there were 280 new cases in Toronto, 182 in Peel Region and 72 in Ottawa.
The province tested 35,015 people in the last 24-hour period and administered an additional 17,424 doses of the vaccine.
According to provincial data, 659 people are being treated in hospital with 280 of them in ICU.
Another seven cases of variants of concern were reported by provincial officials, bringing the total number to 565.
The latest update came as Thunder Bay and Muskoka Simcoe moved back in the lockdown stage of the province’s pandemic response plan on Monday.
The move was made because of rising COVID case numbers in the two regions and rising concern about the spread of new variants of the virus.
But seven other regions are relaxing some public health restrictions amid declining COVID numbers. They include Niagara Region, Chatham-Kent, Middlesex-London, Southwestern, Haldimand-Norfolk, Huron Perth, and Grey Bruce.
