Requirements for Attending School

Requirements for Attending School in Ontario

  • All pupils (kindergarten to Grade 12) entering school in Ontario must be immunized against Diphtheria, Tetanus, Pertussis, Polio, Meningitis, Varicella (chicken pox), Measles, Mumps and Rubella according to the Immunization of School Pupils Act, 1990
  • Parents are required to provide immunization records to their local public health unit. The Health Unit does not automatically receive immunization records from family doctors/community health centres.
  • Not all provinces in Canada or other countries follow the same immunization schedules. Our staff will review the submitted records and advise parents/caregivers if there are missing doses or vaccines and how to go about filling the gaps.
  • A Parent’s Guide to Vaccination

Throughout January 2024, notification letters will be mailed directly to parents of children with missing doses or missing immunization records.

If you need to book an appointment at a Health Unit Immunization clinic, go to our Immunization Clinics section.

Please provide the missing proof of immunization using one of the options listed here:
