Toronto Public Health is reminding families to check their children’s vaccination records for the 2026-2027 school year, with letters going to families of students in Grade 2 (born in 2019) and Grade 11 (born in 2010).
The point that catches most parents out: a child can be fully vaccinated and still be flagged. Public health only knows about a vaccination if it has been reported to them, and doctors’ offices do not report on a family’s behalf.
What the law requires
Under Ontario’s Immunization of School Pupils Act, students attending school must be vaccinated against nine designated diseases or hold a valid exemption. Those diseases are measles, mumps, rubella, diphtheria, tetanus, polio, pertussis and meningococcal disease, plus varicella for students born in 2010 or later.
Students whose records are incomplete by the deadline in their letter can be issued a suspension order. Toronto Public Health says active suspensions begin if the requirements are not met.
How to fix it
Records are reported through Immunization Connect Ontario, known as ICON. Families can check what public health currently has on file, add anything missing, and book any outstanding vaccines.
The practical sequence is: pull your child’s yellow immunization card or ask your family doctor for a record, compare it against what ICON shows, report anything missing, and book an appointment only for the vaccines that are genuinely outstanding.
Families who need help can email [email protected] or call 416-338-7600, Monday to Friday between 8:30 a.m. and 4:30 p.m. The city has posted guidance at toronto.ca/StudentVaccines.
What the city says
“Ensuring the health and safety of students in Toronto is at the heart of our work,” said Dr. Michelle Murti, Toronto’s Medical Officer of Health, in the city’s announcement.
