With the new, more contagious variants continuing to pose significant risks, the Ontario government, in consultation with the Chief Medical Officer of Health, has extended the Stay-at-Home Order (O. Reg. 265/21) until at least June 2, 2021. All public health and workplace safety measures under the provincewide emergency brake will also remain in effect.

During this time, the government will prepare to administer the Pfizer vaccine to youth between the ages of 12 and 17, beginning the week May 31, 2021, as the province also finalizes plans to gradually and safely re-open the province.

With 2.2 million doses scheduled to arrive this week, the provincial government is extending booking eligibility at mass immunization clinics to individuals aged 18 and over. This high number of doses is due to an early delivery of the week of May 24 shipment, to accommodate the long weekend, and is an opportunity for the province to offer an appointment to receive the vaccine to more Ontarians ahead of schedule.

As of 8:00 a.m. on Tuesday, May 18, 2021, individuals aged 18 and over in 2021 across Ontario will be eligible to book a COVID-19 vaccine appointment through the provincial booking system and call centre, or directly through public health units that use their own booking system. Individuals who are 17 years old and are turning 18 in 2021 will also be eligible to book their COVID-19 vaccination appointment only for the Pfizer COVID-19 vaccine. The Pfizer vaccine is currently the only COVID-19 vaccine that has been authorized by Health Canada for use in youth aged 12 and over. The provincial booking system will note which clinics are not offering vaccines for those who are 17 years old.
