Confirmed Cases of COVID-19

Textsize
A+ A-

At HWDSB, we will inform students, families and staff about confirmed cases of COVID-19 in our schools, in alignment with Ministry of Education guidelines.

We will post information to this page when we receive Hamilton Public Health Services (PHS) confirmation of a confirmed COVID-19 case involving a student or staff member in a school setting. To protect their privacy, we will not identify the student or staff member that has tested positive for COVID-19.

If PHS advises HWDSB that a class, cohort or school should be temporarily closed, we will inform the school community immediately.

Find COVID-19 information and resources from Hamilton Public Health Services, the Province of Ontario and the Government of Canada.

*According to COVID-19 Guidance: School Outbreak Management, an outbreak in a school is defined as two or more lab-confirmed COVID-19 cases in students and/or staff (or other visitors) in a school with an epidemiological link, within a 14-day period, where at least one case could have reasonably acquired their infection in the school (including transportation and before/after school care).

**In some instances, the type of case has not been identified as either student/child or staff/provider/partner due to privacy considerations. These “individuals” only include unidentified students/children or staff/providers/partners and not visitors or parents. These cases will be tracked as “individuals” but not included in the “student/child” or “staff/provider” columns.

***Learn more about the outbreak designation placed as a result of confirmed cases at the Education Centre. The outbreak designation was declared over on December 29, 2020.

Confirmed Cases in Schools

The information here will be updated upon notification of confirmed cases by Hamilton Public Health Services (PHS).
