Ontario Prepares to Accelerate Rollout as Vaccine Supply Increases

Published on April 29, 2021

In response to an expected increase in vaccine supply from the federal government, this government is preparing to ramp up our rollout of COVID-19 vaccines to deliver more doses to Ontarians, including further supporting our at-risk communities. This includes a targeted, time-limited commitment to allocate 50 per cent of upcoming vaccine shipments to hot spot communities as identified by postal code, to help decrease COVID-19 transmission and hospitalizations.


Due to a predictable and increased vaccine supply from the federal government, we will be able to further expand delivery channels in the coming weeks to vaccinate more Ontarians faster. To support this, the government has developed an anticipated schedule to expand eligibility to receive the COVID-19 vaccine throughout May, with individuals aged 18 and older eligible to book through the provincial booking system as early as the week of May 24, 2021.


Effective April 30, at 8:00 a.m., individuals aged 55 and over across the province are eligible to book a appointment through the provincial booking system. This same day, a pilot will launch through select pharmacy locations in hot spot communities to administer the Pfizer vaccine to individuals aged 55 and over. This is expected to expand to additional public health units later in May following evaluation of the program and as supply allows.


The following is an anticipated schedule to expand COVID-19 vaccine booking eligibility over the next month, to be further evaluated in advance of each age band drop.
