Ontario COVID-19 Vaccine Administration and Outcomes Data

Government of Ontario data includes daily and total doses administered, individuals vaccinated by age and Public Health Unit, and COVID-19 cases and hospitalizations by vaccination status. The dataset is based on Statistics Canada's 2021 population estimates and reflects totals from 8 p.m. the previous day. This page was last updated on April 17, 2026, but notes that publication of certain status data ceased in 2022.

Use Cases

• Monitor vaccination campaign progress based on daily and total doses administered.
• Analyze vaccine uptake disparities based on data by age group and Public Health Unit.
• Assess vaccine effectiveness against severe outcomes based on hospitalization and ICU data by vaccination status.
• Calculate case rates per 100,000 population based on status and age group data.

Strengths

• Includes multiple granular breakdowns: by age group, Public Health Unit, and vaccination status.
• Population counts are based on Statistics Canada's 2021 estimates.
• Data reflects totals from 8 p.m. the previous day, suggesting daily updates.

Limitations

• Publication of cases, case rates, and hospitalizations by vaccination status ceased in June and July 2022.
• Data entry of vaccination records is still in progress, so dosage data may not be a full representation.
• Data does not include dosage data where consent was not provided, including records from some Indigenous communities.
