Learn what the priorities for Ontario’s covid 19 vaccination plan are based on.

Why get vaccinated

Safe and reliable vaccines can help protect you and your family from covid 19. They are an important tool to help stop the spread of the virus, build immunity in Ontario and allow us to safely resume normal life.

When a large percentage of the population becomes immune to covid 19, the spread of the virus will slow down or stop.

The vaccines approved for use in Canada:

  • will help prevent death and serious illness due to covid 19
  • are anticipated to be effective against the original strain of the virus and the identified variants

Until vaccines are widely available and enough people have been fully vaccinated to stop the spread of the virus, we all must:

How we set vaccination priorities

Ontario’s plan prioritizes vaccines for those at greatest risk of severe illness and those who care for them.

Our strategy to vaccinate the population is based on:

  • age
  • risk due to:
    • health conditions
    • congregate settings
    • hot spots (areas with higher rates of death, hospitalization and transmission)
    • not being able to work from home

This is because evidence shows that vaccinating primarily based on age, with some adjustment for high risk groups, will prevent more:

  • deaths
  • hospitalizations
  • ICU admissions
  • cases of covid 19

To make sure Ontario’s vaccine program is equitable and fair, decisions about priority are guided by:

Collecting sociodemographic data

As part of our commitment to building safe and healthy communities, Ontario is collecting sociodemographic data on a voluntary basis from individuals who get the covid 19 vaccines. We are collecting this data to:

  • get a more complete picture of who is being vaccinated across the province
  • make sure vaccines are provided in a way that is equitable
  • show us where we need to provide more information to address any gaps
  • help ensure that we are reaching everyone who wants to be vaccinated

When you get the vaccine, you may be asked to share information about your:

  • race
  • ethnicity
  • language
  • income
  • household size

Providing this information will be completely voluntary, and safeguards will be in place to protect your privacy.

You will be able to receive the vaccine whether you provide the information or not.

If you change your mind about allowing your information to be used, you can contact the Ministry of Health at If you withdraw your consent, we will stop using your sociodemographic data in the future.

This email is only for questions about sociodemographic data. If you have questions about covid 19 vaccines, read more online or call 1-888-999-6488.
