Information on 2024/2025 enforcement of the Immunization of School Pupils Act (ISPA)
For the 2024/2025 school year, Halton Region Public Health is currently enforcing Ontario’s Immunization of School Pupils Act (ISPA) (external link) for students born 2011, 2012, and 2017 who are missing immunization records with Public Health.
The ISPA requires that all children and adolescents attending school be fully immunized against several designated diseases. Parents/guardians must review and report all vaccines their children receive to Public Health.
Students must have up to date immunization records (or a valid vaccine exemption) for the following ISPA designated diseases:
- Tetanus, Diphtheria, Pertussis, Polio;
- Measles, Mumps, Rubella;
- Meningococcal Disease; and
- Varicella (chickenpox) (required for children born in 2010 or later).
If your child is unable to be immunized for medical reasons, or if you choose not to immunize your child, you must submit a vaccine exemption to Halton Region Public Health. For more details about this process, please visit the Vaccine Exemption for Children page for more information.
Parents/guardians have been notified by mail if their 2011, 2012, and 2017-born child’s record is missing information.
Halton students born in 2011, 2012 and 2017, and whose immunization records are not up to date, have received a school suspension notice effective March 27, 2025. If you received a notice and have questions, please call 905-825-6000 or 311 within Halton Region to speak to a public health nurse.
Please note: If you have recently reported your child’s immunization record, we are currently prioritizing records submitted for students born 2011, 2012 and 2017.
There may be a delay in processing all other records. Thank you for your patience.
