UNDERSTANDING SLP
What is Speech-Language Pathology?
A regulated health profession focused on communication and swallowing disorders
SLP is a Regulated Health Profession
In Ontario, Speech-Language Pathologists are regulated by the College of Audiologists and Speech-Language Pathologists of Ontario (CASLPO). This means they must meet strict education, training, and competency standards to practice. Unlike some therapy providers, SLPs must be registered to call themselves "Speech-Language Pathologists."
Education Requirements
- • Master's degree in SLP (minimum 2 years)
- • Clinical practicum hours (300-400+ hours)
- • National certification exam
- • Ongoing professional development
CASLPO Registration
- • Public registry verification
- • Professional liability insurance
- • Complaints process for consumers
- • Standards of practice enforcement
BENEFITS
How SLP Helps Autistic Children
Communication areas where Speech-Language Pathology makes a difference
| Communication area | Focus | Includes |
|---|---|---|
Expressive Language | Helping children communicate their wants, needs, thoughts, and ideas |
|
Receptive Language | Understanding what others communicate to the child |
|
Social Communication | The back-and-forth of interaction with others |
|
Play Skills | Using play to develop communication naturally |
|
AAC: Augmentative and Alternative Communication
AAC includes all the ways we communicate besides talking. For autistic children, AAC can reduce frustration, support language development, and provide a reliable way to communicate while speech skills develop.
- Low-Tech AAC
- Picture cards, communication boards, picture exchange systems (PECS), and simple sign language
- Mid-Tech AAC
- Simple button devices with recorded messages, basic switches, and single-message communicators
- High-Tech AAC
- Speech-generating devices, tablet apps (Proloquo2Go, TouchChat), and computer-based communication systems
Important: AAC does NOT prevent speech development. Research shows AAC supports speech development by reducing frustration and providing a model for communication.
The services gap
Services exist, but access remains rationed by a waitlist measured in years.
THE PROCESS
What to Expect from SLP Services
From assessment to therapy: what each step involves
- 1
Initial Assessment
The SLP will evaluate your child's communication strengths and challenges through:
- • Parent interview about concerns and goals
- • Structured play observation
- • Standardized tests (if appropriate)
- • Review of previous assessments
Duration: 1-2 hours, often split across sessions - 2
Goal Setting
Based on assessment results, the SLP will collaborate with you to set functional, measurable goals. Good goals are:
- • Specific (clear behavior identified)
- • Measurable (you can see progress)
- • Functional (matters for daily life)
- • Family-centered (aligned with your priorities)
Example Goal: "Child will use 10 different words or pictures to request items across daily routines by [date]." - 3
Therapy Sessions
Regular therapy sessions work on goals through play-based activities and structured practice:
- • Direct therapy with child (30-60 minutes)
- • Parent coaching and home strategies
- • Practice opportunities in natural contexts
- • Regular progress monitoring
Frequency: Typically 1-2 times per week, intensity varies by needs - 4
Progress Review & Discharge
Ongoing evaluation determines whether to continue, adjust, or complete services:
- • Regular progress reports (usually every 3-6 months)
- • Goal revisions as child progresses
- • Transition planning when goals are met
- • Home program recommendations for maintenance
Duration: Varies widely, from 6 months to several years depending on goals

Step 1: Check the OAP Provider List
If you have OAP funding or are on the waitlist, start with the OAP Provider Directory:
- • Visit the OAP website provider directory
- • Search by "Speech-Language Pathology"
- • Filter by your region
- • Note provider names and contact information
Step 2: Verify CASLPO Registration
Before contacting any provider, verify their credentials:
- • Search the provider's name on the CASLPO public registry

Frequently Asked Questions
Common questions about SLP services for autistic children in Ontario
Speech-Language Pathology (SLP) is the professional field, while speech therapy refers to the treatment provided. An SLP is a regulated health professional who assesses and treats communication disorders. Speech therapy is one of the many interventions an SLP may provide. Think of SLP as the medical specialty (like cardiology) and speech therapy as the treatment (like cardiac rehabilitation).
Yes, the Ontario Autism Program (OAP) can cover SLP services as part of your child's core clinical services budget. However, OAP funding must be used with an OAP-approved SLP provider. Coverage amounts depend on your child's needs assessment and available funding. Many families also use extended health benefits to supplement OAP funding for SLP services.
Private SLP services in Ontario commonly run in the low-to-mid hundreds of dollars per hour for individual therapy (rates vary). Initial assessments typically cost a few hundred dollars. Group sessions are less expensive, commonly priced well below the individual rate. Depending on therapy frequency, monthly costs can reach into the thousands of dollars. Always confirm costs upfront and ask about sliding scale options if needed.
As early as possible. Research shows that early intervention during the 0-6 neuroplasticity window produces the best outcomes for communication development. Many SLPs work with children as young as 18-24 months. Early SLP can help establish foundational communication skills before school age and support AAC (Augmentative and Alternative Communication) implementation when needed.
AAC (Augmentative and Alternative Communication) includes tools and strategies that support or replace speech. This ranges from picture exchange systems to speech-generating devices and tablet apps. AAC is often recommended when an autistic child has limited verbal communication or is highly frustrated by communication barriers. Modern SLP practice emphasizes AAC as a support for communication development, not a barrier to speech.
OAP maintains a list of approved providers on their website. You can search for "speech-language pathology" in the OAP Provider List. You can also check the College of Audiologists and Speech-Language Pathologists of Ontario (CASLPO) registry to verify credentials. When contacting providers, ask specifically about their OAP approval status and experience working with autistic children.
Duration varies widely based on the child's needs. Some children benefit from short-term interventions (6-12 months) targeting specific skills. Others may require ongoing support for several years. SLP services are often episodic, intensive periods followed by breaks for practice and reassessment. Your SLP should provide progress updates and recommendations for service duration based on measurable goals.
In Ontario, look for an SLP registered with the College of Audiologists and Speech-Language Pathologists of Ontario (CASLPO). Essential qualifications include: a Master's degree in Speech-Language Pathology, CASLPO registration (verifiable on their public registry), and specific experience or training in autism. Additional valuable qualifications include Hanen certification, PROMPT training, or AAC device expertise. Always verify credentials through CASLPO.
