Autism in Canada: key statistics (2026)

About these figures

This page brings together published figures on autism in Canada, each with its date and a link to its source. Most national figures come from the Public Health Agency of Canada (PHAC). Assessment and support programs are run by the provinces and territories, which publish very different amounts of data, so we say which province each figure covers. Where a figure is an estimate, a single clinic's price, a news report or from outside Canada, we say so. This page does not yet cover programs that exist only in Quebec. All figures were checked on September 29, 2026. If you quote a figure, please cite the original source.

How common is autism in Canada?

About 1 in 44 children and youth in Canada have an autism diagnosis in their health records, and parents report a diagnosis for 3 in 100. These figures come from two different national sources, so they do not match exactly (the next section explains why).

PHAC says the rise in diagnoses may reflect more awareness, broader diagnostic criteria and guidelines that encourage early detection, and that exactly which factors are involved, and how much each matters, is not known (PHAC). It also notes that the health records miss some diagnoses made in private clinics, through schools or in research programs, so the 1 in 44 figure may be an underestimate. PHAC relies mainly on the parent survey to estimate how many children have a diagnosis, and on health records to track trends over time.

Why do Canadian figures say 1 in 66, 1 in 50 or 1 in 44?

They come from different sources, ages and years. Each one counts children with a diagnosis, measured in a different way, so the older figures are out of date rather than wrong.

The Canadian Paediatric Society's 2019 statement on early detection still quotes 1 in 66 (CPS), and many websites repeat it or 1 in 50. PHAC says figures from the survey and from health records are expected to differ, because one relies on what parents report and the other on diagnoses recorded by doctors and hospitals. Both sources agree that diagnoses have increased over time, vary between provinces, are more common in boys and are less common in 1 to 4 year olds than in older children (PHAC).

Are boys more likely to be diagnosed than girls?

Yes. Boys are diagnosed more often, but the gap has narrowed, which PHAC says suggests girls are increasingly being recognized and diagnosed.

At what age are children diagnosed?

Many Canadian children are diagnosed before age 5, and new diagnoses are now most common in the youngest age group.

How long is the wait for an autism assessment?

There is no national figure. The Canadian Paediatric Society says a wait of no more than 3 to 6 months has been recommended, but getting from referral to a team assessment commonly takes more than a year in many Canadian communities (CPS, October 2019).

Waiting often continues after a diagnosis. In Ontario, children are invited to Ontario Autism Program core clinical services in the order they registered (Government of Ontario), and a 2025 survey by the Ontario Autism Coalition found parents had waited at least five years for funding (CBC News, March 2026). In Alberta, provincial caseworkers told their union that families wait three or more years to be assigned an FSCD caseworker (CBC News, June 2026).

If you are waiting now, our guide to waiting for an autism assessment covers help you can get without a diagnosis.

How much does a private autism assessment cost?

There is no official source on typical private costs in Canada. At the clinics we checked in September 2026, published prices ranged from about $2,500 to $5,000. Listing a price is not a recommendation.

Public assessments are free but often take longer, for example through the BC Autism Assessment Network, or with a developmental pediatrician, which provincial health insurance usually covers (CASE Psychology; Autism Calgary). Before paying, check that the report will be accepted for the support you need. Until B.C. Autism Funding ends in March 2027, a private diagnosis used to apply for it must include both the ADOS-2 and the ADI-R, done by a regulated B.C. professional (Government of British Columbia, June 2026). The Ontario Autism Program accepts a written diagnosis from a qualified professional that includes set details, such as the date of the assessment and the professional's name and credentials (Government of Ontario). PHAC notes that private diagnoses may not appear in the health records behind the national 1 in 44 figure.

Provincial autism programs in numbers

Each province runs its own programs, and these figures change often. They are dated; check the official page before you rely on one.

Federal benefits in numbers

Most federal disability money for children depends on the Disability Tax Credit (DTC). Autism does not qualify automatically: the Canada Revenue Agency looks at how much the impairment limits everyday life, for at least 12 months (CRA).

What do we know about autistic students?

School data on autistic students are limited, and each province publishes them differently.

How common are co-occurring conditions?

Many autistic children have another condition as well. Pain or illness can show up as a change in behaviour, so it is worth asking your family doctor or pediatrician to check.

How we keep these figures up to date

We check each source when it publishes new data and update this page. The date at the top of the page shows when the figures were last checked.

If you need support now, our where to get help page lists Canadian helplines and services, including the 9-8-8 Suicide Crisis Helpline and Kids Help Phone.
