ABA uses learning principles to teach skills and reduce behaviours that get in a child's way. Plans should be individual and reviewed with the family. Suitability, evidence, availability, and expected outcomes depend on the individual service and provider. Confirm each claim before relying on it for a care decision.
Public coverage and private prices vary. Confirm current eligibility with the relevant program and request an itemized written quote from any private provider.
These are general process questions worth asking any aba provider — not claims about a specific provider's answers.

Ontario does not publish a current province-wide private ABA price. Ask each provider for an itemized written quote and confirm current OAP eligibility before committing funds.
Behaviour services may qualify under OAP when current program, provider, and service rules are met. Registration or an active funding agreement is not proof of service receipt.
Ontario does not publish a comparable province-wide average wait for ABA. Ask AccessOAP about program status and providers about their current intake timelines.
Ask who is accountable for the plan, verify current Ontario registration through the relevant public register, and ask how goals, data, consent, safety, and complaints are handled.
