COVID-19 Contact Tracing Initiative

Ontario’s local public health units (PHUs) are responsible for COVID-19 contact tracing and case management. Ontario residents who have COVID-19 are contacted by their local public health unit to identify persons they were in contact with and could have transmitted the virus to, and supported throughout their self-isolation period. Public health units also follow up with contacts of COVID-19 cases to check-in about symptoms and to provide additional supports as needed.

Visit our COVID-19 webpage for more information about COVID-19.

What is the COVID-19 Contact Tracing Initiative?

Contact tracing, notification, and follow up is a process that is used to identify, educate and support individuals who have had close contact with someone who has tested positive for an infection. These individuals are at a higher risk of testing positive for that infection. Contact tracing can help individuals who have been in contact with a case of COVID-19 understand their risk and limit further spread of the virus.

Please note:
Public Health Ontario does not contact individuals by email or text message about potential COVID-19 exposure or testing results.
A text message phishing scam to individuals’ cell phones is using PHO email addresses. Do not respond to any text message or email claiming to be from PHO or from an email address or phone number associated with our organization.

For more information about phishing see the Canadian Anti-Fraud Centre page.
