Report Your Immunizations

Every time your child gets an immunization from their healthcare provider, you need to update the Health Department. Learn about reporting your immunizations to the Halton Region Health Department.

Important Information

  • Health care providers do not automatically report immunizations to their local public health units. We may not have an immunization record if:
    1. you or your parent/guardian did not report the immunizations to Halton Region Public Health. Under the Immunization of School Pupils Act, parent(s)/legal guardian(s) are responsible for updating Public Health every time their child receives an immunization;
    2. you recently moved to Ontario;
    3. you received your immunization from a health care provider or pharmacist (health care providers do not report immunizations to Halton Region Public Health); or
    4. you were born before 1980.
    Contact your family physician or previous clinics where you have been immunized. When physicians retire or relocate to another practice, you may be able to get help locating records by contacting the Advisory Services Department with the College of Physicians and Surgeons at 1-800-268-7096, ext. 603.
  • If you are using our online immunization reporting tool (external link) to report immunizations, please note it may take up to 15 business days to view your child’s updated immunization record. Our Public Health team is experiencing a higher than usual number of records being submitted at this time. We thank residents for their patience and understanding.
    • Please note: It is not necessary to report COVID-19 vaccines received in Ontario, as it is already recorded in the province’s COVID-19 immunization data base.
