Pre-registration for COVID-19 Vaccination

Pre-registration is only available for provincially-prioritized groups. This includes healthcare workers (outlined here), high-risk congregate living settings (outlined here) and essential workers who cannot work from home (outlined here).

For a list of which groups are currently eligible to receive the COVID-19 vaccine, please click here.

Vaccine booking process in the London and Middlesex County region:

  1. Please have only one contact person submit the pre-registration survey for your organization. This contact person should have a leadership role within the organization (e.g. CEO, Lead professional) as they will receive all vaccine-related information and communication from the Middlesex-London Health Unit (MLHU). Please note that if you are self-employed, you are the leader of your organization.

  2. To pre-register, this contact person must submit the pre-registration survey found below. The survey asks you to indicate which group best describes the work done by your organization. Please select from the list at the end of this page. People who do not fit within one of the groups identified by the Ontario Ministry of Health are not eligible in Phase 2 and are not able to pre-register at this time.

  3. Eligible people will then follow the booking instructions. Please note that walk-ins will not be accepted at COVID-19 vaccination clinic locations.

For questions about eligibility, please contact

Provincially-prioritized groups

People who do not fit within one of the groups identified by the Ontario Ministry of Health are not eligible in Phase 2 and are not able to pre-register at this time.


Healthcare Workers

Please allow 3 business days to process your pre-registration. If eligible, the Middlesex-London Health Unit will send an email to the contact person, which will contain the appointment booking information (a username and password will be required) and can be shared confidentially with eligible staff members.

Where a health sector has been named in the priority group, all workers in that sector are included (e.g. including custodial, security and reception staff). Where a non-health sector setting has been identified (e.g., schools), only workers providing a health service or direct patient care in that setting are to be included.
