University Guidelines for COVID-19

Key Guidance:

The McMaster vaccination policy has been paused as of May 1, 2022.  All new hires to the University will still be required to be fully vaccinated.  Vaccination requirements for students, visitors, volunteers and contractors will be paused.

Individuals can significantly reduce their risks associated with COVID-19 by getting a booster vaccination.  For more information about scheduling your vaccine booster go to  Although not mandatory, COVID-19 booster rescripts can now be uploaded to MacCheck.

Masking indoors will continue to be required until at least the end of May due to this most recent increase in COVID-19 cases in Ontario.  Wearing masks indoors will provide an added layer of protection and will help to reduce risk of infection as well as spread throughout the McMaster community.  Individuals can reduce their risk by also continuing to mask outside of the workplace especially in high occupancy or high risk areas.  Level 3 surgical masks will continue to be provided by the University at no cost to individuals who wish to wear one.

Masking requirements may differ pending work and/or study location.  Individuals must follow the site-specific masking requirements.

Physical distancing is no longer mandatory in university settings with the exception of eating/drinking.  Where masks are removed for eating/drinking in work spaces such as meeting rooms, shared offices and lounges, physical distancing must be maintained.  Physical distancing is not required during eating/drinking in discretional spaces such as restaurants, eateries and at catered events.

As a best practice to help prevent the spread of COVID-19, consider physical distancing where possible and/or attempt to give space to others.


Basic hand hygiene practices are important in protecting our overall health.  Continue to follow good handwashing practices, washing your hands often with warm water and soap for at least 20 seconds or use hand sanitizer with at least 60% alcohol content when water is not available.

It’s especially important to wash your hands:

  • Before eating or preparing food.
  • Before touching your face.
  • After using the restroom.
  • After leaving a public place.
  • After blowing your nose, coughing, or sneezing.
  • After handling your mask.

Continue to keep high touch point areas clean.  Wipe down surfaces frequently including light switches, keyboards, mouse, phone, desk, etc.

Although daily MacCheck screening is no longer required, it is still important to monitor your health daily before arriving to your work or study location.  If you are feeling unwell stay home, not only to allow yourself to rest and recover but to prevent the spread to others.  This is a common courtesy we must extend to all members of our university community.  The university requires all individuals accessing campus to complete the Ontario COVID-19 Self-Assessment tool.  MacCheck will continue to be available for individuals who wish to use it but will no longer be mandatory for most settings.  Individuals working in FHS locations should continue to follow regular screening protocols as required which may include the use of MacCheck.

Be alert for symptoms.  Watch for fever, cough, shortness of breath, or other symptoms of COVID-19.

Reporting is not required for those that are working and learning remotely, and have not attended in-person activities within the last 14 days, and are not attending in-person activities in the next 14 days. This reporting tool is for those who are attending or planning to attend in-person McMaster activities, and for clinical learners who will need to report as per protocols at both their host hospital/placement and in the COVID-19 Reporting Tool in Mosaic.
