To reduce the spread of all respiratory viruses, including COVID-19, anyone who feels sick should stay home and complete the self-assessment tool to learn more about what to do next. Find out if you are eligible for COVID-19 treatment, continue to follow public health measures and stay up-to-date with your vaccinations including a COVID-19 booster for the best protection.

The Ministry of Health has shifted the focus of case and contact management to residents who are most vulnerable, including those associated with high-risk settings (e.g. hospitals, long term care). You are considered a close contact of COVID-19 if any of the following apply:

  • You live with, or are a close contact of, someone who has tested positive on a PCR, Rapid Molecular, or Rapid Antigen test
  • You live with, or are a close contact of, someone who has been told by Toronto Public Health that they are a “probable case” of COVID-19
  • You live with, or are a close contact of, someone who is not eligible for testing but likely has COVID-19 based on their symptoms

For directions on what to do if you are a close contact or have been exposed to COVID-19, take the Ontario Ministry of Health’s COVID-19 Self-Assessment.

Are you a parent or caregiver of a child who may be a close contact of someone with COVID-19? Refer to Respiratory Viruses: Information for Parents & Caregivers for more information.

If you have been told that you are a close contact, you do not need to self-isolate (stay home), unless you develop symptoms. For a total of 10 days from the last day you saw the person with COVID-19 you should:

  • Self-monitor for symptoms of COVID-19. If you develop any symptoms, self-isolate (stay at home) and you may seek testing and treatment, if eligible. Learn more on when to seek medical attention.
  • Wear a well-fitted, high quality mask when in public settings, especially if they are crowded or have poor ventilation
  • Avoid non-essential visits to vulnerable individuals (e.g. seniors) and highest risk settings (e.g., hospitals, long-term care).

If you are a close contact who lives in a high-risk setting (e.g. long-term care, or other congregate setting), you may need to self-isolate. 

If you are a close contact who works/volunteers/attends a high-risk setting, and do not have any symptoms of COVID-19, you can continue to work while self-monitoring for symptoms for 10 days from your last exposure to the person with COVID-19. Speak to your employer and follow any additional workplace measures.

To find out if you are eligible for publicly-funded COVID-19 testing, visit the provincial website.

If you have a Rapid Antigen Test (RAT) at home, you can take it yourself. Visit our Testing page for details about what to do after completing a RAT or PCR test.

The provincial government is distributing RAT kits for use at home.


After your self-monitoring period, Toronto Public Health recommends that you continue to practice prevention measures. These include hand washing and physical distancing, where possible. Toronto Public Health also recommends wearing a well-fitted, high quality mask when in indoor public settings, especially if they are crowded or have poor ventilation or if you are around people who are at higher risk (such as seniors or those with a weak immune system). Masks are especially recommended for people at higher risk of getting seriously sick from COVID-19. Masks are still required in some settings.

If you have questions about self-monitoring and how to stop the spread of COVID-19, call Toronto Public Health at 416-338-7600.
