You may have to self-isolate depending on which of the three scenarios below applies to you:

a. If you have symptoms of COVID-19, you must self-isolate – go to our symptoms page to find out if you have COVID-19.

    • Previously tested positive for COVID-19 (including a Rapid Antigen Test) in the last 90 days
    • 18 years or older and boosted dose
      • Boosted means received a COVID-19 vaccine booster dose 3 months or more after a primary vaccine series. For most people, the booster dose is their 3rd dose
    • 17 years and younger and are fully vaccinated

c. If you do not live with a person with COVID-19, you do not need to self-isolate, unless you develop symptoms. You must self-monitor for 10 days after your last exposure to the person with COVID-19.

Self-Isolation Information

  • Self-isolation means that you must stay home, keep away from others, wash your hands often with soap and water, cover your coughs and sneezes, and wear a well-fitted mask.
  • Read the how to self-isolate fact sheet for more information.
  • If you cannot isolate at home, you may qualify to stay at the Toronto Voluntary Isolation Centre (TVIC). You can refer yourself to TVIC by calling 416-338-7600.

  • Self-monitor for symptoms for 10 days after you last had close contact with the person with COVID-19.
    • If you do not know the last day you had contact with the person with COVID-19, check for symptoms every day for 10 days from receiving this text.

 4. Tell Others

  • Tell your employer that you have been exposed to someone with COVID-19 and advise them that you need to self-isolate or self-monitor (whichever applies to you).
    • Follow any restrictions from work, as specified by your employer.
  • If you develop symptoms, tell the people you live with that they may need to self-isolate.
  • If you need in-person medical care, tell them that you are a close contact.

 5. Protecting Others

  • For the 10 days after your last exposure to the person with COVID-19, even if you do not need to isolate, you must:
    • Self-monitor for symptoms
    • Wear a well-fitted mask in all public places, including while exercising or playing sports. Avoid activities that require mask removal (e.g. dining out).
    • NOT visit or attend work at high-risk settings (e.g., hospitals, long-term care homes, or congregate living settings) and NOT visit individuals who may be at higher risk for illness (I.e., older adults, those that have a weak immune system).
