Sep 23, 2021 – Updated vaccination guidelines for Ontario


On September 14, the Ministry of Health released updated COVID-19 Guidance for Individuals Vaccinated outside of Ontario/Canada to align with Public Health Agency of Canada’s (PHAC) COVID-19: Recommendations for individuals who are living, working, or studying in Canada and who have received a non-Health Canada approved vaccine.  

The guidance states that in Ontario, an individual is considered fully vaccinated if they have received: 

  • The full series of a Health Canada-approved COVID-19 vaccine and any combination of such vaccines;
  • One or two doses of a COVID-19 vaccine that is not authorized by Health Canada, followed by one dose of a COVID-19 mRNA vaccine authorized by Health Canada; or
  • Three doses of a COVID-19 vaccine that is not authorized by Health Canada; and
  • It has been at least 14 days since their final dose of their COVID-19 vaccine. 

If you are considered fully vaccinated as described above, no further vaccination is required at this time. Please ensure you upload your proof of vaccination to YU Screen as soon as possible.

If you are not considered fully vaccinated as described above, we encourage you to get your remaining dose or doses as soon as you are eligible and to upload your proof of vaccination to YU Screen.  

All York community members who are coming to campus for classes or in-person activities must be fully vaccinated with the full series of an accepted COVID-19 vaccine or combination of vaccines and must upload proof of vaccination to YU Screen in order to continue accessing York’s campuses in person by October 18, 2021. York will directly communicate with the full community about the date by which those requiring a third dose will be required to provide proof of their third dose.

If you have received one or two doses of a COVID vaccine not yet approved by Health Canada, please review the guidelines from the Ministry of Health to determine your remaining course of vaccination.
