Autism is a widely recognized neurodevelopmental difference affecting roughly 1-2% of Canadians.
Yet, getting an autism diagnosis can feel complicated, and many people, especially women, BIPOC, and LGBTQ+ adults, go undiagnosed until later in life.
If you suspect you might be autistic, you may begin to explore the possibility of a diagnosis as an adult. This can be especially true as you start to consider if autism runs in your family, and reflect on whether autism may be a contributing factor in your challenges.
Pursuing an adult autism assessment in Canada can unlock several benefits, including accommodations, neurodiversity-affirming therapy, and community supports.
However, the decision to pursue a diagnosis is entirely up to you and what fits your needs.
Below you'll find what autism looks like in adults, who can diagnose it, the costs to expect, and a clear roadmap for getting evaluated.
Autism is a lifelong neurodivergence where individuals process information and interact with the world differently, which can present unique strengths alongside challenges.
Classified as chronic, autism may impact day-to-day functioning and impact school, interpersonal relationships, and home life. Adults, in particular, may experience difficulties in the workplace, often related to navigating a world that was not built for neurodivergence.
Key Traits of autism in Adults
Autism manifests through various traits and affects social communication, sensory processing, and patterns of interest.
These autistic traits exist on a "spectrum, ” meaning no two autistic individuals have the same combination of traits or intensity within these traits.
Common adult presentations include:
Social-Communication & Emotional Traits
Difficulty reading social cues or maintaining eye contact
Scripted speech or literal interpretation of language
Challenges in forming or sustaining friendships
Rejection Sensitive Dysphoria (RSD) or fear of criticism
Difficulty understanding or interpreting emotions
Repetitive Interests & Behaviours
Being focused on one or more “special interests” makes redirecting attention difficult.
Stimming (hand-flapping, rocking, hair twisting, etc.)
Arranging things in a particular order
Sensory & Executive-Function Challenges
Sensory sensitivities or sensitivity to light, sound, or texture.
Executive dysfunction or difficulty with planning, memory, and task initiation
Autistic inertia or difficulty initiating or changing tasks
Low motivation due to having to navigate a world that is not built for neurodivergence.
Masking or hiding your autistic traits to match social norms.
Autism is also linked with higher rates of anxiety, bipolar disorder, and depression.
Why Many Adults Miss an Autism Diagnosis
There are stereotypes that autism affects only cisgender white boys
Girls, women, and gender-diverse folks often mask traits.
Healthcare providers may lack neurodiversity-affirming training.
Cultural stigma deters BIPOC communities from seeking assessment.
Benefits of an Adult Autism Diagnosis in Canada
Legal accommodations at work or school under provincial and federal law
Access to neurodiversity-affirming coaching and therapy
Greater self-understanding and community connection
Potential eligibility for disability grants, tax credits, and bursaries
How to Get Diagnosed as Autistic as an Adult in Canada
Step 1: Seek Out a Healthcare Professional
Start with your family doctor or nurse practitioner as your first point of contact to begin your assessment process.
If they have experience diagnosing autism, they may be able to provide you with a diagnosis that could be covered by your provincial health insurance.
But if they do not feel competent enough in diagnosing autism, they may refer you to a psychiatrist (covered by provincial health) or a registered psychologist (private fee).
Step 2: Estimate Cost
Psychiatric assessment: covered by provincial plans, but with long wait-lists.
Private psychological assessment: faster, but $1,500 – $4,000+.
Explore funding (e.g., Bursary for Students with Disabilities).
Step 3: Book an Appointment
Once you have determined the cost and have chosen a practitioner, schedule your appointment via phone, email, or an online booking system, depending on the provider's preferences.
Step 4: Gather All Relevant Information
Now that your appointment is booked, prepare:
List of current challenges & how they affect daily life
Medical and mental-health history
Childhood report cards or developmental notes
Family history of neurodivergence
Past cognitive or psychological tests
Bringing comprehensive documentation can greatly assist the provider in making an informed diagnosis.
