COVID-19 Contact Tracing

Ontario’s local public health units are responsible for COVID-19 contact tracing and case management.

About COVID-19 Contact Tracing

Contact tracing, notification and follow up is a process that is used to identify, educate and monitor individuals who have had close contact with someone who is infected with the virus that causes COVID-19. These individuals are at a higher risk of becoming infected and sharing the virus with others. 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.
