Child immunization

Report your immunizations onlineImmunization helps protect your child against serious and potentially life-threatening illness.

In Ontario, children are eligible for free vaccinations for several communicable diseases. These include  polio, tetanus, diphtheria, pertussis, measles, mumps, rubella, influenza (“flu”), and numerous others. 

Required immunizations for school children 

All children attending school between ages 4 to 17 need to be immunized according to Ontario’s Immunization Schedule. Children must have proof of immunization against many diseases, including meningococcal disease, whooping cough and chickenpox* to attend school. Children who are not fully immunized may not be allowed to attend school unless an exemption form is provided. 

If your children are not vaccinated, they are at risk of contracting these diseases or spreading them to others   For more information about immunization, including a schedule of free vaccinations for children in Ontario, please see the parent resources below. 

If you have questions, please call 519 539-9800 (toll free: 1 800 755-0394) and ask to speak to a public health nurse about immunization.

* Chickenpox only applies if the child was born on or after January 1, 2010.
