Immunization of School Pupils Act

The Immunization of School Pupils Act is a law in Ontario, Canada, that requires children and adolescents under the age of 18 to receive certain vaccinations to attend primary and secondary school unless a valid exemption is provided, which includes medical, religious, and conscience exemptions. The law applies to both private and public schools. ISPA was adopted in 1990 and was last amended in 2017.
