When will I be eligible for a second dose?

According to the government of Ontario, as of May 28, 2021, second doses are already being offered to certain groups, including high-risk health care workers, individuals with certain health conditions and First Nations, Inuit and Métis individuals.

In addition, the AstraZeneca COVID-19 vaccine is being offered at an accelerated pace with a 10-week interval for individuals who received their first dose between March 10 to March 19, 2021. Acceleration of AstraZeneca second doses will proceed on a 12-week interval, with booking eligibility based on date of first dose.

How can I book my second dose appointment?

There are several vaccination clinic options available across Ontario’s public health regions: mass immunization clinics, pop-up / mobile clinics, hospital and pharmacy clinics. Please note that not all clinic types are available in every region, and are dependant on local planning done by public health unit.

Second dose appointments can be rebooked through the provincial booking system, and through your local pharmacies. For those in public health units who use their own booking system, or if you received your first dose from your primary care provider or through a pop-up clinic, more information will follow on how and when second dose booking and rebooking will be available.
