Immunization Side Effects

For children attending school in Ontario, a written immunization record or proof of immunization is required, by law, for diphtheria, tetanus, polio, measles, mumps and rubella unless there is a valid written exemption. Parents/guardians are required to provide this information to their local public health unit, and to update the information as necessary.

Children attending licensed childcare centres should be immunized according to their age and as recommended in the Publicly Funded Immunization Schedules for Ontario – 2009 or as current. You may contact your local public health unit for more information.

You may decide because of medical, religious or philosophical reasons not to immunize your child. In this case, you will need to provide a valid written exemption to your local public health unit. If the disease appears in your child’s school or childcare centre, your child may have to stay out of school/childcare until the disease is no longer present.
