In Ontario, school age is determined by specific age requirements set by the Ministry of Education. These requirements help ensure children are developmentally ready for school when they start.

Kindergarten Eligibility

Children are eligible for kindergarten in Ontario if they will be 5 years old on or before December 31 of the school year. The exact cutoff date varies by school board, but most use December 31 as the reference point.

Kindergarten Eligibility Formula:

If (Child's Age on December 31 ≥ 5 years) then eligible for kindergarten.

Some school boards may have slightly different requirements, so it's always a good idea to check with your local school board for specific information.
