To protect Ontario’s progress in the fight against COVID-19 and safeguard the province’s hospitals and intensive care units (ICUs) in the face of the rapidly-spreading Omicron variant, the Ontario government is:

• Rapidly accelerating its booster dose rollout by expanding eligibility to all individuals aged 18 and over starting on Monday December 20 at 8AM
• Shortening the interval to get your third dose to three months following an individual’s second dose 

Starting Monday, December 20, 2021, individuals aged 18 and over will be eligible to schedule their booster dose appointment through the Ontario’s booking portal, by calling the Provincial Vaccine Contact Centre, through Indigenous-led vaccination clinics, participating pharmacies and primary care settings. Appointments will be booked three months (84 days) after a second dose as the province urgently expands booster eligibility to millions more individuals. Additionally, pharmacies and other channels may provide boosters for 18 and over at the three-month interval starting Friday, December 17, 2021 for walk-ins.

In addition, starting today, individuals aged 50 and over as well as all those currently eligible who have already booked their appointment at an interval of six months (168 days) can call the Provincial Vaccine Contact Centre to re-book for an earlier date at the three-month interval and can change their appointment through Ontario’s booking portal starting on Monday.
