Most families worry about admission. Admission is a single conversation, and if it goes badly you find out immediately and keep looking.
That does not mean admission is unprotected. As the table above sets out, refusing a child because of their disability may itself be discrimination in the provision of a service, and is actionable.
But the harder problem is the exit. A private-school placement rests on a tuition contract, and a contract can end. If a school decides in November that your child’s needs have grown beyond what it can manage, there is no identification to revisit, no placement decision to appeal, no tribunal, and no obligation on any other private school to take your child instead. You return to your home board mid-year, and start the identification process you never began.
That is the asymmetry worth understanding: in the public system a bad decision is slow, procedural and appealable. In a private school it can be a phone call.
This is also why a funding entitlement, if Ontario ever created one, would not by itself help. Money that follows a child to a school which need not admit them, need not keep them, and need not write a plan for them is not a placement. It is a subsidy. We looked into who is proposing that, and what we found →
For context on scale: of roughly 1,445 independent schools in Ontario, 57 emphasize special education — about 3.9% of the sector, on the count published by an organization that supports funding them. Some of those 57 schools are excellent, and this page is not an argument against them. It is an argument about what a family can enforce.
