Immunization of School Pupils Act (ISPA)

Halton Region Public Health is currently enforcing Ontario’s Immunization of School Pupils Act (ISPA) (external link).

Halton students born in 2007 to 2010, and whose immunization records are not up to date, have received a school suspension notice effective February 13, 2025. If you have a high school student who has been suspended, and have questions, please call 311 or 905-825-6000 to speak to a public health nurse.

Halton students born in 2011, 2012 and 2017, and whose immunization records are not up to date, are at risk of school suspension starting March 27, 2025, unless the required information is provided to Halton Region Public Health.

To avoid school suspension, Public Health is encouraging parents/guardians who have not updated their child’s records to complete the following actions as soon as possible:

  • Review the student’s record and submit any required information. For students who are 16 or older, or for those having trouble logging in to the online reporting system (ICON), please follow the instructions on our Report Your Immunizations webpage to access the online record.
  • Parents with questions about their child’s record are encouraged to have their 16/16+ student call 311 to speak to a public health nurse. Alternately, if consent is provided at the time of the call, the parent or guardian can speak on the student’s behalf.
  • If the student requires immunization, arrange to receive the vaccine dose(s) through their health care provider. If the student’s health care provider cannot provide the vaccine, check availability at a Public Health Community Immunization Clinic.

More information on immunizations required for school attendance

Please note:
  • All immunization records submitted to Public Health are reviewed and processed by staff. We are currently prioritizing records submitted for secondary students born 2007 to 2010.
  • Records submitted after 6 p.m. on February 12, 2025 may be processed on the following business day. If this is the case, the student may still be suspended.
  • Secondary students and/or parents/guardians are encouraged to login to Immunization Connect Ontario (ICON) to verify the online record has been updated and to make sure no additional vaccines are required.
  • Please continue to submit your records to Public Health. 
  •  If your child was born after 2010, outside of this secondary school enforcement cohort, there may be a delay in updating their immunization record. Records for elementary students born between 2011 and 2017 may take 2 to 3 weeks to process. Thank you for your patience during this time.
