Province Providing an Extra Layer of Protection Against COVID-19 and Variants


News Release

TORONTO — The Ontario government, in consultation with the Chief Medical Officer of Health, is accelerating COVID-19 vaccine booster dose eligibility to Ontarians aged 50 and over and additional high-risk individuals, providing an extra layer of protection against COVID-19 and its variants.

Starting on Monday, December 13, 2021 at 8:00 a.m., individuals aged 50 and over will be eligible to schedule their booster dose appointment through the COVID-19 vaccination portal, by calling the Provincial Vaccine Contact Centre, through Indigenous-led vaccination clinics, select pharmacies and primary care settings. Appointments will be booked for approximately six months (168 days) after a second dose.

In addition, due to a higher risk of severe illness from COVID-19, effective immediately individuals receiving dialysis (hemodialysis or peritoneal dialysis) are eligible to receive a third dose of the COVID-19 vaccine if it has been 56 days since their second dose. Also effective immediately, the province is recommending re-vaccination with a new COVID-19 vaccine primary series post-transplantation for individuals who receive hematopoietic stem cell transplants (HSCT), hematopoietic cell transplants (HCT) (autologous or allogeneic), and recipients of CAR-T-cell therapy, due to the loss of immunity following therapy or transplant.

Beginning in January, Ontario will further expand eligibility for booster doses based on age and risk, with an interval of six to eight months from the second dose.

“If you are eligible for a booster dose of the COVID-19 vaccine, please book your appointment as soon as you can to provide yourself with an extra layer of protection,” said Dr. Kieran Moore, Chief Medical Officer of Health. “If you have not yet received the vaccine, please do so today. This includes vaccinations for children aged five to 11. Achieving the highest vaccination rates possible remains our best tool to protect us, reduce the risk of COVID-19 transmission, and fight the significant surge of new cases and the new Omicron variant.”

While the best defence against the Omicron variant remains containing it at the border, Ontario has the infrastructure in place to rapidly identify, trace and isolate COVID-19 and its variants. In addition to accelerating booster doses the province is taking several other measures in the fight against COVID-19 and its variants, including:

  • Further expanding free PCR testing at all testing centres to asymptomatic individuals who have returned from, or travelled in, Nigeria, Malawi and Egypt between November 1st and December 6th, 2021, including family and other household contacts of travellers. The province is also distributing 11 million rapid antigen screening tests to all public schools and participating First Nation schools for each student to take home five tests to use over the holidays and throughout the return to in-person learning in January. The province will also launch a holiday testing blitz this month, with additional pop-up testing locations at high-traffic locations in higher-risk regions.
  • Releasing enhanced guidance on case, contact and outbreak management for individuals that may have been exposed to the Omicron variant to mitigate further transmission. This includes more frequent follow up calls to ensure adherence to isolation, not permitting a shortened duration of isolation for asymptomatic fully vaccinated individuals with a positive test, requiring isolation for all high-risk contacts regardless of vaccination status or previously positive status, and offering supports for isolation as needed.
  • Building unprecedented hospital capacity by investing $5.1 billion to add 3,100 beds to the system across the province. This significant increase in capacity has helped ensure that hospital and intensive care capacity continues to remain stable.

“Regardless of what we learn about the Omicron variant, Ontario is prepared to quickly respond to any scenario to protect the health and safety of Ontarians,” said Christine Elliott, Deputy Premier and Minister of Health. “Vaccines continue to be our best protection against COVID-19, and I encourage everyone to book their first, second or booster dose as soon as you are eligible.”

As part of the province’s efforts to vaccinate as many eligible individuals as possible, a limited supply of the single dose Johnson & Johnson COVID-19 vaccine will also be available starting today. The Johnson & Johnson vaccine will be available to individuals aged 18 and over who have an allergy or contraindication to mRNA vaccines or at the request of an individual who has not yet been vaccinated by contacting their public health unit.

In addition to vaccines, clinical trials for molnupiravir, an investigational oral therapy for the treatment of COVID-19 began on October 19, 2020 and is currently in progress at the University Health Network in Toronto and Juravinski Hospital in Hamilton. If approved, molnupiravir will be a five-day oral treatment for high-risk unvaccinated patients with mild to moderate COVID-19 and could be the first such treatment that can be taken outside of a health care facility. Ontario is preparing a strategy for the deployment of approved treatments, ensuring access where it is most needed in the province.

“Getting vaccinated is the best way to protect ourselves, our families and our communities from COVID-19 which is why we’re expanding vaccine eligibility for booster shots while also providing Ontarians aged 18 or older who have not yet been vaccinated, with the option to request the Johnson & Johnson COVID-19 vaccine,” said Solicitor General Sylvia Jones. “With every first, second, third or booster dose administered, we’re increasing Ontario’s immunity and taking another step forward in this battle against the COVID-19 virus.”


Quick Facts

  • As of December 2, 2021, Ontario has administered more than 23 million doses of the COVID-19 vaccine, with 90 per cent of Ontarians aged 12 and over having received at least one dose and more than 87 per cent having received a second dose. Ontario has more than 133,000 doses of the paediatric COVID-19 vaccine.
  • With this expansion approximately 4.6 million additional Ontarians are now eligible to receive a booster dose of the vaccine, for a total of about 5.7 million.
  • Ontario was the first jurisdiction in Canada to begin offering third/booster doses to select vulnerable populations. To date, Ontario has administered more than 696,000 third/booster doses to Ontarians, including to 20 per cent of individuals aged 70 and over.
  • Public health units continue to conduct thorough case and contact management, with the provincial average for contacts reached within 24 hours from November 12 to November 18 at over 94 per cent.
  • Ontario continues to maintain significant testing capacity with results available quickly. As of December 1, 83.4 per cent of tests were processed within 24 hours and 94.6 per cent within 48 hours, well above provincial targets. The province continues to report one of the lowest rates of active cases in the country.
  • The third and booster doses do not change the definition of who is fully vaccinated against COVID-19.
