Vaccine Schedule

Vaccines trigger a child's immune system to make antibodies to fight disease. Vaccines work best when received on time according to the Ontario Immunization Schedule. The vaccines on the immunization schedule are free, made available by the Ontario government.

If you do not have a health care provider, contact Public Health to discuss your options to ensure your child receives their vaccines. If you have a question about your child's immunization, contact:

  • A public health nurse by calling 519-575-4400 between 9 a.m. and 4 p.m., Monday to Friday
  • Your health care provider

Older children may be eligible for new vaccines now available in Ontario. Check with your health care provider or Public Health to see if your older child qualifies.

Vaccines used in Canada are very safe. They are developed in accordance with the highest standards and are continually monitored for safety and effectiveness.

Minor side-effects from vaccines are common but go away quickly. These can include mild fever and some redness, swelling or tenderness at the spot where the vaccine was administered.
