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.

How is OAP funding determined?
OAP Core Clinical Services funding is determined by a "Determination of Needs" interview. Based on age and support intensity, annual funding ranges from $6,600 to $65,000. This envelope must cover all eligible therapies (ABA, Speech, OT) and technology for the year.

What are the out-of-pocket costs for autism therapy?
Private ABA therapy costs $100-$150/hour (BCBA supervised). Intensive programs of 20+ hours/week can cost up to $95,000 USD/year (2020 US cost estimate cited in FAO 2020 report; Canadian costs vary). Speech and OT cost $120-$160/hour. These costs are often prohibitive while families wait 5+ years for OAP funding.
Beyond hourly rates: BCBA supervision, initial assessments, parent coaching, and materials add $15,000–$25,000+ to the real annual cost of ABA in Ontario.
Direct answer
Beyond the RBT hourly rate, a full intensive ABA program involves BCBA supervision (10–20% of total therapy hours at $100–$180/hour), initial assessment ($1,500–$3,000), annual reassessment ($1,000–$2,500/year), parent coaching (typically 2 hrs/month at BCBA rates), curriculum materials, and possibly travel time. These add-ons can increase the true annual cost of a 20-hour/week program by $15,000–$25,000 above base RBT rates. With 69,166 children waiting for OAP, families paying privately need the full picture.

Full cost breakdown for a 20-hour/week program
Direct therapy (RBT hours): $50–$80/hr — approximately $52,000–$83,000/year. The visible number. Not the full picture. BCBA supervision (10–20% of therapy hours): $100–$180/hr — approximately $5,200–$18,700/year. Required for ethical, high-quality programs.
Initial BCBA assessment plus program design: $1,500–$3,000 one-time, before therapy begins. Ask if included. Annual reassessment: $1,000–$2,500/year, every 6–12 months. Parent coaching sessions: $100–$180/hr at BCBA rates — approximately $2,400–$4,320/year (2 hrs/month). Strongly affects outcomes. Materials, reinforcers, curriculum: $200–$800/year. Visual aids, token boards, edible reinforcers. Clinical reports and written updates: $150–$500/report. Check whether reports are included. Therapist travel time (home-based programs): varies by agency — may add $50–$150/week. Some agencies bill travel at a reduced rate.
Why these costs are often missed
ABA providers typically quote an hourly rate for direct therapy. That is the cost of the RBT sitting with your child — the most visible component. It is also the lowest-cost professional in the program. What is rarely in the headline quote: the BCBA supervising the RBT, the assessment and program design that starts before the first therapy session, the parent coaching that makes the program work at home, and the ongoing reporting.
A 30-hour/week program at $60/hr for RBT time looks like $93,600/year. Add BCBA supervision at 15% of those hours at $140/hr, an initial assessment, 2 parent coaching hours per month, annual reassessment, and materials — and the real cost is closer to $110,000–$125,000 per year. This is not unusual. It is normal for high-quality programs. The Ontario Autism Program funds all of these components within Core Clinical Services for enrolled children. The problem is that 69,166 children are waiting for that enrollment — paying these full costs privately in the meantime.
What to ask before signing a contract
What is the total monthly cost, all-in? Ask for an itemized estimate covering therapy hours, BCBA supervision, assessments, parent coaching, reports, and any other charges. How are BCBA hours billed? Are they included in the therapy rate or invoiced separately? How many BCBA hours per week are provided?
Is the initial assessment included or additional? When does it happen and what does the cost include? What is your cancellation policy? Is there a charge for cancellations within 24 or 48 hours? What is the policy if the therapist cancels? Are progress reports included? How often are they produced? Is there a per-report charge? Do you charge travel time? What is the travel billing policy for home-based programs? What happens if my RBT leaves? What is the typical timeline to assign a new therapist? Get the contract reviewed by someone familiar with ABA services before committing.

Frequently asked questions
Beyond the direct therapy (RBT) hourly rate, a full intensive ABA program typically involves several separately-billed components: BCBA supervision hours (10–20% of total therapy hours at $100–$180/hour), an initial BCBA assessment and program design ($1,500–$3,000), annual or semi-annual reassessments ($1,000–$2,500/year), parent coaching sessions, curriculum materials and reinforcers ($200–$800/year), and possibly therapist travel time. These add-ons can increase the true annual cost of a 20-hour/week program by $15,000–$25,000 above the base RBT rate.
BCBA supervision is a professional and ethical requirement for ABA programs. BCBA stands for Board Certified Behaviour Analyst. The BCBA designs the treatment program, trains and supervises the RBT(s), reviews data, adjusts goals, and ensures the program remains evidence-based. If an agency tells you BCBA supervision is included in the RBT hourly rate, ask for written clarification of how many BCBA hours are provided per week.
Initial BCBA assessment and program design typically costs $1,500–$3,000 and happens before therapy begins. Annual or semi-annual reassessments typically cost $1,000–$2,500. These assessments include standardized tests, skills assessments, direct observation of your child, and the production of a written treatment plan and progress report. Some agencies bundle assessment costs into a monthly or annual program fee; others bill them separately.
Yes, in most programs. Parent coaching — sessions where the BCBA teaches the parent to implement ABA strategies at home — is generally billed at BCBA rates ($100–$180/hour) and is separate from your child's direct therapy hours. A typical program involves 2 parent coaching hours per month, adding approximately $2,400–$4,320 per year to program cost. Parent involvement is strongly associated with better outcomes — so this is not a cost to skip; it is a cost to budget for.
Before signing any ABA therapy contract, ask about: billing for therapist travel time; cancellation policy (some clinics charge 50–100% for cancellations with less than 24–48 hours notice); whether clinical reports and progress reports are included or billed separately ($150–$500 per report); how staff turnover is handled; what happens if the BCBA changes; and how rate increases are communicated.
