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.

As of June 1, McMaster’s masking mandate is paused, but masking is strongly encouraged especially in indoor settings. 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 are required to follow site-specific masking requirements.

Physical distancing is no longer mandatory in university settings. As a best practice to help prevent the spread of COVID-19, consider physical distancing where possible and/or attempt to give others space.


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.

MacCheck is no longer required for university locations. Individuals are required to complete screening using the Provincial COVID-19 self-assessment tool prior to attending university locations.

Active screening may still be required in specific FHS locations. MacCheck will continue to be available for those who are required to use it as part of their screening processes.

McMaster staff and faculty members are required to report positive COVID-19 cases, as confirmed through a Rapid Antigen or PCR test, through the Mosaic COVID-19 reporting tool. Students are no longer required to report cases. Learners in health profession programs should check with their program offices for instructions on reporting to placement locations.

Public reporting of COVID-19 cases on the Back to Mac website will be paused.
