Three-Phase Provincial Distribution Plan

We are currently in Phase 2 of Ontario’s COVID-19 Vaccine Distribution Plan.

The Government of Ontario has developed a three-phase vaccine distribution plan which sets the order and priorities for distribution for local public health units to follow. The groups selected in each phase are based on an ethical framework established by the province. The Government of Ontario has committed to distributing COVID-19 vaccines to priority populations in the highest risk areas as shipments are received from federal government suppliers.

The Role of the Ministry of Health and Long-Term Care is to:

  • Source the supply of vaccines.
  • Identify priority groups.
  • Allocate and monitor vaccine supply across Ontario.
  • Distribute the vaccine supply to public health units.

The Role of the Windsor-Essex County Health Unit (WECHU) is to:

  • Securely store local vaccine supply and ensure cold chain is maintained.
  • Coordinate and/or administer the vaccine to identified priority groups.
  • Monitor and report local data on vaccine distribution and uptake.
  • Coordinate, oversee, and/or hold vaccination clinics to administer the vaccines to Windsor-Essex County residents.

Local COVID-19 Vaccine Rollout Plan:

The WECHU’s local COVID-19 Vaccine Rollout Plan builds off the 3-phase provincial distribution plan, but is broken down into three stages based on vaccine supply. We are currently in Stage 2 of our local COVID-19 Vaccine Rollout Plan.

Priority Populations for COVID-19 Vaccination

The vaccine prioritization described on this website is intended to provide an overview of the groups involved in each phase of the Provincial Vaccine Distribution Plan. Specific sectors identified within the phases will be notified directly by the Windsor-Essex County Health Unit (WECHU) or another agency or organization when they are eligible to receive the vaccine. The WECHU is committed to timely communication on vaccine availability and will communicate broadly when there are opportunities to register for the vaccine.

The following populations will receive the COVID-19 vaccine in the first phase of distribution:

  • Residents, employees and staff, and essential caregivers of congregate living settings that provide care for seniors,
  • Health care workers in accordance with the Ministry of Health’s guidance on Health Care Worker Prioritization (see live registration forms and more information for health care workers),
  • Adults in First Nations, Métis, and Inuit populations,
  • Adult recipients of chronic home health care, and
  • Adults 80 years of age and older.

Please note that individuals from Phase 1 who have not yet been vaccinated will continue to be prioritized and eligible for vaccination in Phase 2.

Individuals may be eligible in more than one Phase 2 group. When there is overlap, please follow the earliest vaccination opportunity that is presented. Please note that individuals from Phase 1 who have not yet been vaccinated will continue to be prioritized and eligible for vaccination in Phase 2.
