A

ABA (Applied Behavior Analysis)

ABA

Evidence-based therapy using behavioral principles to teach skills and reduce barriers to participation. Evidence-based and supported by ABA research (AAP, NCAEP) when delivered early and intensively, typically 20 to 40 hours weekly.

Note: ABA is the primary evidence-based intervention funded through OAP Core Clinical Services.

AccessOAP

Ontario government's central intake organization for the Ontario Autism Program. Handles registration, waitlist management, and intake coordination. Phone: 1-833-425-2445. Website: accessoap.ca.

Note: First point of contact for all OAP-registered families. Register immediately after autism diagnosis, waitlist position is based on registration date.

B

BCBA (Board Certified Behavior Analyst)

BCBA

A credentialed behavior analyst who designs and supervises ABA programs. BCBAs hold a graduate degree and pass a national certification exam. In Ontario, they are registered with the College of Psychologists and Behaviour Analysts of Ontario (CPBAO) as of July 2024.

Note: OAP Core Clinical Services funding can be used to hire a BCBA for program design and supervision.

Behaviour Therapist (BT)

BT

A frontline therapist who delivers ABA therapy sessions directly with an autistic child, under the clinical supervision of a BCBA. Also called Registered Behaviour Technician (RBT) in some contexts.

C

Core Clinical Services

The OAP-funded intensive therapy services families wait for. Includes ABA, IBI, speech-language pathology, and occupational therapy delivered at a clinically appropriate intensity. Currently have 5+ year waitlists.

Note: This is what the 91,974+ children on the OAP waitlist are waiting to access.

D

DON (Determination of Needs)

DON

An OAP assessment conducted by an independent clinical expert that evaluates a child's support needs and determines their annual funding level. Funding ranges from $6,600 to $65,000 per year.

Note: Families are invited for a DON assessment only after they reach the front of the waitlist, which currently takes 5+ years.

DSM-5

Diagnostic and Statistical Manual of Mental Disorders, 5th Edition. Published by the American Psychiatric Association, this is the standard diagnostic reference used by psychologists and physicians to diagnose autism in Canada. The DSM-5 unified Asperger's syndrome, PDD-NOS, and autistic disorder under the single diagnosis 'Autism Spectrum Disorder (ASD)'.

DTC (Disability Tax Credit)

DTC

A federal non-refundable tax credit for Canadians with disabilities, reducing income tax payable. Children with autism typically qualify. The 2025 disability amount is $10,138 (CRA), plus a supplement of $5,914 for children under 18. Also unlocks the RDSP.

Note: Apply using Form T2201, completed by a medical practitioner.

E

FAO (Financial Accountability Office of Ontario)

FAO

An independent office of the Legislative Assembly of Ontario that produces reports on government finances and programs. The FAO has published critical analyses of OAP waitlist data and funding levels used extensively as primary sources on this site.

FOI (Freedom of Information)

FOI

Formal requests submitted under Ontario's Freedom of Information and Protection of Privacy Act (FIPPA) to obtain government records not publicly available. FOI requests have been used by advocates and journalists to obtain OAP waitlist numbers, service delivery statistics, and internal correspondence.

Foundational Family Services (FFS)

FFS

OAP supports available to ALL registered families regardless of their waitlist position. Includes parent training, caregiver-mediated intervention workshops, and support navigation. No waitlist.

Note: FFS does NOT replace Core Clinical Services. A few hours of parent training per month is not equivalent to the 25+ weekly hours of intensive ABA therapy that evidence supports.

G

IBI (Intensive Behavioural Intervention)

IBI

A comprehensive, intensive application of ABA principles often delivered in the range of 20 to 40 hours weekly as individualized with a clinician. Most studied with young children (ages 2–5). Funded through OAP Core Clinical Services.

Note: Many children age past the commonly described early intervention window (0–6 years) while waiting for OAP Core Clinical Services.

IEP (Individual Education Plan)

IEP

A legal document created by a school for a student with identified special education needs. Details the student's current levels of achievement, annual program goals, specific accommodations, and any specialized equipment or services. Must be reviewed at least once per school year.

Note: Every Ontario student with an exceptionality is entitled to an IEP. Parents have the right to participate in IEP development.

Invitation System

The current OAP access model where families wait to be "invited" to apply for Core Clinical Services based on their registration date. Families cannot self-refer for funding, they must wait for the Ministry to contact them.

Note: With 91,974+ children registered, the invitation system means most families wait 5+ years before receiving any funding.

IPRC (Identification, Placement, and Review Committee)

IPRC

A school committee process that formally identifies a student as having an exceptionality (such as autism) and determines their educational placement. IPRC decisions must be documented in writing. Parents have the right to be present, to disagree, and to appeal.

Note: Requesting an IPRC meeting is how families formally trigger school-board obligations for special education supports.

J

MCCSS (Ministry of Children, Community and Social Services)

MCCSS

Ontario government ministry responsible for administering the Ontario Autism Program (OAP), developmental services, children's aid, and social assistance programs. AccessOAP operates under MCCSS.

N

OAP (Ontario Autism Program)

OAP

The Ontario government program providing autism services and funding for children and youth under 18. Administered by the Ministry of Children, Community and Social Services (MCCSS) through AccessOAP.

Note: As of 2025, 91,974+ children are registered in the OAP. Fewer than 1 in 4 are receiving Core Clinical Services funding.

ODSP (Ontario Disability Support Program)

ODSP

Income and employment support program for adults (18+) in Ontario with disabilities. Relevant for autistic adults who have aged out of the OAP. Provides monthly income support and benefits coverage.

OHIP (Ontario Health Insurance Plan)

OHIP

Ontario's provincial health insurance plan. Covers OHIP-insured diagnostic assessments for autism by physicians and psychiatrists, as well as speech-language pathology and occupational therapy delivered in hospitals and community health centres.

Note: OHIP-covered autism assessments are free but may have long wait times (commonly reported at 12–24 months). Private assessments commonly cost roughly $2,500–$4,000 but are faster (confirm with providers).

Occupational Therapy (OT)

OT

Therapy addressing sensory processing, fine motor skills, daily living activities, and social participation. Commonly involved in autism support. Available through OHIP in hospitals, community health centres, and privately through OAP Core Clinical Services funding.

P

PPM 140

Ontario Ministry of Education Policy Program Memorandum 140 (2007). Directs school boards to support and fund Applied Behaviour Analysis (ABA) for students with autism. Establishes ABA as the evidence-based approach within the Ontario education system.

Note: Under PPM 140, school boards must have ABA professionals on staff to support students with autism.

Psychoeducational Assessment

A comprehensive evaluation by a registered psychologist that typically assesses cognitive abilities, academic achievement, and behavioral/emotional functioning. May include an autism diagnosis. Commonly required for IEP development and accommodations (e.g., EQAO exemptions, university accommodations). Cost: $3,000–$5,000 privately; available through school boards but wait times are 1–3 years.

RDSP (Registered Disability Savings Plan)

RDSP

A federal long-term savings plan for Canadians with disabilities who hold a valid Disability Tax Credit (DTC) certificate. Contributions attract federal Canada Disability Savings Grants (up to $3,500 annually) and Canada Disability Savings Bonds (up to $1,000 annually for lower-income families). Designed for long-term financial security.

Respite Care

Temporary care for a person with a disability, providing caregivers with a planned break from their caregiving responsibilities. In Ontario, respite care for families of children with autism can be funded through SSAH (Special Services at Home). Critical for preventing caregiver burnout.

S

SLP (Speech-Language Pathologist)

SLP

A regulated health professional addressing communication, language development, speech production, and (in some cases) feeding and swallowing. SLP services are among the most commonly needed by autistic children. Available through OHIP, school boards, community health centres, and privately through OAP Core Clinical Services funding.

SSAH (Special Services at Home)

SSAH

Ontario Ministry of Children, Community and Social Services program providing funding for families caring for a child or adult with a developmental disability or physical disability at home. Can fund respite workers, support workers, and life skills programs. Apply through your local DSSAB (District Social Services Administration Board).

T

WHO (World Health Organization)

WHO

The United Nations' global health authority. WHO guidelines on autism (2023) endorse early, intensive, evidence-based intervention as the standard of care. Advocates have noted that Ontario's 5+ year OAP waitlists fall significantly short of recommended by the WHO timelines for timely autism intervention.

Note: WHO guidelines are referenced throughout this site as the international benchmark advocates argue Ontario is not meeting.

How many hours of ABA therapy does a child need?

Verified

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.
