Summary of Public Health & Workplace Safety Measures

  • Stay home if you have any symptoms of illness, or test positive for COVID-19.
    • Stay home until symptoms have improved for 24 hours (or 48 hours if gastrointestinal symptoms), and you have no fever.
    • If you test positive, but have no symptoms, you do not need to stay home unless symptoms develop.
    • Following symptoms or a positive test, you should wear a mask in all public settings, not visit anyone who is at higher risk of illness, and avoid non-essential visits to high risk settings (e.g., hospitals, long-term care and retirement homes) for 10 days.
    • Individuals who live in a high risk setting, are immunocompromised, or have been hospitalized for COVID-19 related illness, should isolate for at least 10 days and until symptoms have been improving for 24 hours (or 48 hours if gastrointestinal symptoms), and you have no fever.
  • Staying up to date with your COVID-19 vaccinations is highly recommended to help us live with and manage COVID-19.
  • Businesses and organizations may choose to have passive screening signage and/or safety plans. Downloadable and printable signage is available here.
  • Wearing well-fitted masks in indoor public settings is still highly recommended and may be required in certain indoor settings, including:

Variants of Concern

Variants are viruses that have changed or mutated.

All viruses change over time and can lead to variants. While most variants have little impact on the properties of the virus and the impact it has on the community, some can have a larger impact.

Variants are common with coronaviruses, however, a variant becomes a VOC when its changes have a clinical or public health significance that affects one or more of the following:

  • transmissibility (spread)
  • virulence (severity of disease)
  • vaccine effectiveness
  • diagnostic testing

The latest information about variants of concern is available on Public Health Ontario’s website.
