Ontario COVID-19 Data Tool

The Ontario COVID-19 Data Tool provides epidemiological information on COVID-19 activity in Ontario to-date. Explore the most recent COVID-19 data including: daily and weekly case counts by hospitalizations and deaths, vaccine uptake by age, sex and public health unit, outbreaks and laboratory testing.

Changes to the Ontario COVID-19 Data Tool as of September 30, 2022:

  • Summary: The number of Ontarians who have ‘completed their primary vaccine series and 2 booster doses’ and corresponding vaccination coverage estimates were added to the Summary tab
  • Summary, Vaccines and Vaccine Map: Current population projections for Ontario are now being used to calculate vaccination coverage estimates for Ontario and public health units, by age group and sex. This update could result in changes in vaccination coverage estimates. See the Technical Notes – Vaccines for more information.


  • Testing and case, contact, and outbreak management in Ontario was restricted to high-risk populations and settings in January 2022. As such, counts are an underestimate of the extent of COVID-19 activity in Ontario.

The COVID-19 Data Tool is updated Fridays at 11:30 a.m. Vaccine data is updated bi-weekly on Fridays.
