TORONTO -- Nearly a year after the first infection was found in the province, Ontario reached a significant milestone in the fight against COVID-19 on Dec. 14, 2020.

On that date, the first dose of a vaccine against the novel coronavirus was administered in the province.

Now, as more doses become available and more needles go into arms across the province, many questions remain.



50 and older: The province launched an online booking system for mass immunizations. Anyone 50 years of age who lives in a region using this booking system can now sign up for a shot.

This age threshold is expected to drop every week through the month of May until everyone over the age of 18 is eligible.

40 and older: Residents who are 40 years of age and over can get the Oxford-AstraZeneca vaccine at pharmacies and doctor’s offices by appointment. Here is the full list of pharmacies.

60 and under with a health condition: The province says that hospitals and primary care providers will be contacting eligible patients with a high-risk condition to get a COVID-19 vaccine. These individuals will get the vaccine at their primary place of care, but officials say they will "shortly" be able to book through the provincial system.

Education workers: Education workers across Ontario who provide daily support to students with special education needs will be eligible for the COVID-19 vaccine. In addition, all education workers who live or work in high-risk neighbourhoods in Toronto and Peel Region will be able to get their vaccine.

Child-care workers: Ontario child-care workers in licensed facilities are now eligible to get the COVID-19 vaccine. Officials say that a letter will be provided to workers by their employer and that letter must be present at the vaccination appointment. Those in this group must book an appointment using the province's call centre.

People who cannot work from home - Group 1: This group became eligible to book a shot using the province's booking portal on May 6. Employees include elementary and secondary school workers, workers who respond to critical events, people in enforcement, inspection and compliance roles such as law enforcement, workers in childcare, foster care agency workers, agriculture and farm workers, and funeral, crematorium and cemetery workers.

18 and older in Ontario hot spots: All adults living in one of Ontario's 114 high-risk neighbourhoods can now schedule their COVID-19 vaccine appointment through the provincial booking system.

Adults in this demographic can also get the COVID-19 vaccine at mobile and pop-up clinics. These clinics will be organized by local community groups. Individuals should book an appointment through their local public health unit.

18 and older in Peel Region: Every person 18 and over in Peel Region is eligible to book a COVID-19 vaccine appointment using the region's website. For people unable to book an appointment online they should call 1-888-999-6488

35 and older in a York hot spot: York Region is using both the provincial system and has it's own booking portal for COVID-19 vaccines. Officials have said that adults aged 35 and older living in the following priority neighbourhoods are able to get the vaccine using the region's system: L4L, L6A, L4K, L4J and L3S.


The Ontario government has launched a web portal to help with booking appointments for the general population. The portal went live at 8 a.m. on March 15.

For those with a red and white health card, or anyone who is not comfortable using the online tool, the province has also launched a call centre. The Provincial Vaccine Information Line number is 1-888-999-6488.

As part of their individual strategies, each local public health unit will outline where residents can sign up to receive their vaccine. Residents in the regions of Durham, Halton and Peel will not be able to use the province’s web portal, as they have opted to stick with their own booking systems.

On March 15, the province released a list of which public health unit was using their portal.

Some individual hospitals are also using their own booking system, found on their websites.The University Health Network is allowing people between the ages of 18 and 49 who live in the M5V, M6E and M6H postal codes to register for their first dose of the vaccine.

Hamilton: Hamilton residents turning 70 years old this year or older can book an appointment using the province’s booking portal. Anyone in that age category unable to use the portal or who may not have a valid Ontario photo health card should call the public health unit’s COVID-19 hotline at 905-974-9848 and choosing option seven.

York Region: Residents in York Region will transition to using both the provincial online booking tool and the provincial call centre. More information can be found here. York Region has said that it is now vaccinated residents aged 70 and over.

Peel Region: Residents in Peel Region has opted to use their own online booking tool or phone line to book vaccinations. Officials said residents in the 50+ age category, or their caregiver, can book a COVID-19 vaccine appointment at the William Osler Health System Vaccine Clinic through an online booking tool or by phone at 905-494-2120, ext. 56685.

Halton Region: Officials said an online booking system is available or residents can call 311 if assistance is required. Halton has said that it is now vaccinated residents aged 70 and over.

Durham Region: Officials said an online booking system is available.

Toronto: Officials have set up a website that allows residents to pre-register or book a vaccine appointment, but will transfer to the provincial booking portal and call centre on March 15. Mass vaccination clinics in Toronto are scheduled to begin administering doses of the vaccine on March 17.

Initially, Ontario residents receiving the Pfizer-BioNTech COVID-19 vaccine were advised to receive their second dose 21 days after the first dose. As well, those receiving the Moderna vaccine were advised to receive their second dose within 28 days of their first.

On Feb. 14, the provincial government said all second dose appointments for the Pfizer-BioNTech vaccine will be conducted within 35 days and no later than 42 days of receiving the first dose to increase availability during a supply-limited time. This new messaging does not apply to residents of long-term care, high-risk retirement and First Nations elder care homes, as well as residents of other types of congregate care homes for seniors and those 80 years of age or older.


Residents of Ontario can contact their local public health unit for further information on vaccine rollout plans.
