Anyone in Ontario age 12 and older is now eligible for COVID-19 vaccine. To get your vaccine, visit the provincial booking system or call 1-833-943-3900 to make an appointment for first or second doses.

The Pfizer, Moderna and COVID-19 vaccines require you to have two doses to be fully vaccinated. NOTE: The National Advisory Committee on Immunization now recommends that the Pfizer and Moderna vaccines are the preferred ones to get for your first and second doses. Both Pfizer and Moderna can be used interchangeably with each other if needed. Currently, Ontario continues to offer all three of these vaccines (AstraZeneca included).

Timing for Second Dose

In Ontario, the second dose for vaccines is now given up to 112 days after the first dose. Due to increasing vaccine supply, the Province has announced updated timelines to further shorten the period for people to get a second dose of COVID-19 vaccines based on age and other criteria.

  • Starting June 21, anyone who received their first dose of the Pfizer or Moderna vaccines on or before May 9 will be eligible to book (or rebook) their second dose appointment at a shorter interval.
  • Starting the week of June 28, everyone in Ontario 18 years of age and older who received a first dose of the Pfizer or Moderna vaccines will be eligible to book a second dose appointment.
  • If you received the AstraZeneca vaccine as your first dose, you can now get your second dose after eight to 12 weeks. Your second dose can be AstraZeneca, Pfizer or Moderna, as Ontario is now allowing the mixing of vaccines if desired.

If you book a new second dose appointment at a shortened interval through the provincial booking system, you will receive an email confirming the cancellation of your original second dose appointment. This is normal.

If you book a new second dose appointment at a shortened interval through a pharmacy or primary health care provider, you must go into the provincial booking system to cancel your original second dose appointment.
