Ontario is reporting a record 4,183 people in hospital with COVID-19, including 580 people in intensive care.
That's up from 3,887 in hospitals on Monday, though not all hospitals report data from the weekends.
There are 37 new COVID-19 deaths being reported today.
Ontario is reporting 7,086 new cases of COVID-19, though Public Health Ontario has said the number is likely higher because of a current policy restricting who can access tests.
Eighty-two per cent of Ontario residents aged five and older have received two doses of a COVID-19 vaccine and 88 per cent have at least one dose.
About 56 per cent of long-term care homes in the province have active COVID-19 outbreaks.
