Direct answer
The RBT (Registered Behaviour Technician) delivers direct therapy with your child. The BCBA (Board Certified Behaviour Analyst) designs the program and supervises. Ontario regulates applied behaviour analysis through the College of Psychologists and Behaviour Analysts of Ontario (CPBAO). BACB credentials can still be checked at bacb.com/registry.
Role: Front-line therapy provider; implements the ABA program with the child.
Education: No degree required; 40-hour training curriculum, competency assessment, and written exam.
Credential: BACB RBT certification. RBTs should work under qualified clinical supervision.
Supervised by: BCBA at minimum 5% of billable hours per BACB standards.
Compensation: Typically $20–$35/hour employment rate; billed to families at $50–$80/hour.
Role: Clinical supervisor; designs, oversees, and adjusts the ABA program.
Education: Master's degree in behaviour analysis or related field; BCBA-D is doctoral-level.
Credential: BACB BCBA certification — 2,000 supervised fieldwork hours + BCBA examination.
Responsibilities: Assessment, program design, RBT supervision, family training, progress reviews.
Compensation: $60–$120/hour supervision; $100–$180/hour for direct assessment.
The BACB maintains a free, public registry at bacb.com/registry. Search by name or certificate number to confirm active certification and check disciplinary history. For Ontario regulation, also check whether the clinical supervisor is registered with CPBAO when applicable.
For OAP-funded services, ask your service provider to share the supervising BCBA's certificate number before services begin. This is a standard quality practice — not an unusual or confrontational request.
For private therapy, apply the same check. Ask providers which Ontario regulator or credentialing body applies to each staff role, and where complaints should go if care is unsafe or unethical.
Ontario now regulates applied behaviour analysis through the College of Psychologists and Behaviour Analysts of Ontario (CPBAO). This changes older advice that described ABA as having no Ontario regulator.
Technician roles still depend on supervision. Ask who is legally and clinically responsible for the program, whether that person is registered with CPBAO when applicable, and how concerns or complaints are handled.
Practical implication: verify BACB credentials when used, ask about supervision ratios, and request the supervisor's registration or certificate number before services start.

Compared regulatory bodies for SLP and OT (which DO have provincial colleges)
ABA therapy in Ontario typically costs $50–$80/hr for RBTs and $100–$180/hr for BCBAs. How OAP funding compares and what families pay privately.
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.
Give your current OAP provider 30 days notice, then select a new provider from the OAP-approved list. Contact your regional MCCSS office for the current approved provider registry.

How much does ABA therapy cost in Ontario?
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.

What is the difference between BCBA and RBT?
A BCBA (Board Certified Behavior Analyst) holds a master's degree and provides clinical supervision, program design, and oversight. An RBT (Registered Behavior Technician) delivers direct hands-on therapy under BCBA supervision. Both are essential roles in delivering effective ABA therapy programs in Ontario.

Is there a shortage of autism therapists in Ontario?
Ontario faces a critical shortage of Board Certified Behavior Analysts (BCBAs). Only a few thousand BCBAs are registered in Canada, with uneven geographic distribution leaving Northern Ontario with fewer than 20 BCBAs serving millions of residents. Even families with OAP funding often cannot find a qualified provider, turning approved funding into effectively unusable vouchers. The shortage compounds the 71,263 child waitlist crisis.
