ABA therapy in Ontario costs $50-$150 per hour depending on provider credentials. Monthly costs for intensive programs (20-40 hours/week) range from $4,000 to $24,000. OAP funding covers a portion, but families typically face significant out-of-pocket expenses during the sensitive early intervention period.

Research indicates optimal early behavioral intervention for young children typically requires 25-40 hours per week for 2-3 years to achieve maximum developmental gains. EIBI (Early Intensive Behavioral Intervention) is one evidence-based approach supported by meta-analyses (Reichow et al., Cochrane 2018). The Early Start Denver Model (ESDM), studied by Dawson et al. (2010) in toddlers aged 18–30 months, is a related naturalistic developmental behavioral intervention showing significant IQ and adaptive behaviour gains.

The OAP includes: 1) Core Clinical Services (needs-based therapy funding), 2) Foundational Family Services (free webinars/coaching), 3) Caregiver-Mediated Early Years (parent coaching for toddlers), 4) Entry to School (school readiness), and 5) Urgent Response Services (short-term crisis intervention).
