Important News
York Region opening additional vaccine appointment King Clinic Inc.
Jul 12, 2021

On Tuesday, July 13, 2021 at 8:00 a.m., approximately 58,000 COVID-19 vaccine appointments will be available to anyone age 12+ who lives, works or goes to school in York Region who:

  • Wants to book a first dose appointment
  • Has received their first dose of a COVID-19 vaccine and wants to book a second dose appointment
  • Wants to book an earlier second dose appointment

New appointments can be booked online or by phone by visiting or by calling Access York at 1-877-464-9675.

Previously booked second dose appointments will be honoured and will not be cancelled unless a new and earlier appointment is confirmed.

Walk-ins available for first doses 

To remove barriers for those who have been unable to receive a first dose of a COVID-19 vaccine, York Region will now accept walk-ins for first doses at the following clinics:

  • Aaniin Community Centre in the City of Markham (12+)
  • Maple Community Centre in the City of Vaughan (12+)
  • Georgina Ice Palace in the Town of Georgina (12+)
  • Ray Twinney Complex in the Town of Newmarket (12+)
  • Richmond Green Centre in the City of Richmond Hill (12+)
  • SoccerCity Drive Thru in the Town of Whitchurch-Stouffville (18+)
  • Trisan Centre in the Township of King (12+)

The Cornell Community Centre in the City of Markham will begin accepting walk-ins for first doses as of Tuesday, July 13, 2021. All other vaccination clinics, including pop-up clinics, remain by appointment only.

If you haven’t received your first dose of a COVID-19 vaccine, visit a York Region clinic as soon as you are able and get your shot.

York Region is exploring options for additional walk-in clinics for first doses. Information on when and where these clinics will operate will be communicated through, on social media and through trusted media partners.

Due to the increasing circulation of the Delta variant throughout the province, it remains critically important for all those who have not received a first dose to get one.

Closure of COVID-19 vaccine clinic at Cortellucci Vaughan Hospital

The vaccine clinic located at Cortellucci Vaughan Hospital closed at end of day Sunday, July 11, 2021. The closure of the vaccine clinic will allow Mackenzie Health to focus its efforts on providing hospital care to residents throughout York Region now that Cortellucci Vaughan Hospital has opened as a full-service hospital. Individuals who already have a previously booked appointment between Monday, July 12, 2021 and Saturday, July 31, 2021 will have their second dose appointment automatically rebooked to the vaccine clinic at Maple Community Centre. To the greatest extent possible, appointments will be rebooked for the same date and time, with some exceptions. All residents impacted by the change will be notified by e-mail.

New drive-thru clinic at Emily Carr Secondary School

York Region has opened a new drive-thru COVID-19 vaccination clinic at Emily Carr Secondary School in the City of Vaughan. The clinic will run weekly Sunday to Wednesday until August 18, 2021 and is available for individuals age 12+ who live, work or go to school in York Region and want to receive their first or second dose of a COVID-19 vaccine. Appointments are required; visit to book an appointment.

mRNA Vaccines (Pfizer-BioNTech and Moderna)

Due to limited supplies of Pfizer-BioNTech vaccine, Moderna vaccine will be used for all first and second doses appointments for individuals age 18+ at all York Region Public Health-run clinics through to at least Sunday, July 18, 2021. Individuals age 12 to 17 will receive Pfizer-BioNTech vaccine, as it is the only vaccine currently authorized by Health Canada for use in this age group.

Both the Pfizer-BioNTech and Moderna mRNA vaccines are over 90% effective at preventing serious illness and death due to COVID-19. The National Advisory Committee on Immunization (NACI) considers these mRNA vaccines to be interchangeable, if the same product is not readily available.

If the vaccine you received for your first dose is not available at your second dose appointment, it is recommended you receive the mRNA that is available rather than delaying your second dose. Individuals who received their first dose of an mRNA COVID-19 vaccine can receive their second dose at a shortened interval of no less than 28 days.

York Region Public Health is working with our local health care partners to provide COVID-19 vaccines at various locations across York Region. Clinic dates and times vary for each location. Please visit for specific clinic details.

New appointments will be released as vaccine supply becomes available. We encourage individuals to check back regularly. To ensure appointments are available to everyone, we encourage residents to book only one appointment per person.

Contact Public Health if you have questions about COVID-19 vaccines

Residents have questions about COVID-19 vaccines, and it helps to speak with someone you can trust. You can call York Region’s Health Connection at 1-800-361-5653 to speak with a public health nurse about COVID-19 vaccination to help you make an informed decision.

Given the expected high volume of web activity and telephone support associated with each appointment release, wait times may be longer than usual and service disruptions on york.camay occur. We thank you for your patience and ask you continue to be kind to one another and our staff.
