Learn Ontario’s immunization schedule from AboutKidsHealth

It is important for children to receive routine immunizations to protect them against many life-threatening infectious diseases.

Children get their vaccines based on a schedule determined for their province or territory. The following is a vaccine schedule for infants and children in Ontario. Provincial and territorial schedules change frequently — to see the current recommended vaccination schedules for the rest of Canada, consult the Public Health Agency of Canada’s comprehensive chart.

For more information on immunizations and how children who have not been fully immunized can “catch up”, visit www.aboutkidshealth.ca.

Before vaccinating, talk to your child’s doctor if your child has any of the following conditions:

  • If they have had an allergic reaction to a previous vaccination.
  • Seizures or a serious neurological disease.
  • If your child is immunocompromised. Live virus vaccines live and divide inside a person who is vaccinated, which means they can cause the disease if a child’s immune system is already very weak. As a result, children who are immunocompromised should not receive live virus vaccines such as chickenpox or MMR.
  • Children with an egg allergy can get all routine immunizations, but it is possible for certain types of flu vaccines to cause an allergic reaction in a child allergic to eggs.
