How Canadian Hospitals Are Using AI for Early Autism Risk Detection
Canadian hospitals now use AI for early autism screening, enabling faster diagnosis and timely support for children.
Take a busy pediatrician and imagine him/her staring at a chart full of numbers: heart rate, blood tests, prenatal ultrasounds. Beneath such data points, there may lurk hints, like the tracks in the snow, that can guide us to the understanding that a child has an increased risk of getting autism.
Artificial intelligence (AI) is the new method that hospitals in Canada are relying on to identify those footprints sooner than ever. Doctors expect these new AI tools to indicate intimidation of warning signs instead of just waiting for symptoms to manifest themselves based on regular health data.
The prevalence of Autism spectrum disorder (ASD) in Canada is 1 in every 50 children and youth. It is a neurological disorder and may cause difficulties in social interaction, communication and learning. We understand that early detection is not in vain: the sooner autism is detected, the children can get speech therapy and behavioral support and other services when their brain is still developing and developing.
Early diagnosis is of great benefit to a developing child in that it offers the child the opportunity to access the supports at the earliest time possible. However, in Canada no screening program of autism is available universally, and many families have to wait and not know what to expect.
That is why the researchers are enthusiastic about AI. Suppose a computer was allowed to scan through the health history of a newborn - prenatal tests, ultrasound, hospital treatment, etc. - and indicate a potential patient requiring special care, such as toddlers. This is comparable to employing a data detective: the AI would scan through millions of data points in order to identify patterns that humans may not notice.
According to the words of CHEO pediatrician Dr. Christine Armour, AI can tease out very subtle differences in very large datasets. This is to say that machines are able to identify small signals that are embedded in the noise of health records.
How AI Analyzes Early Health Records to Predict Autism Risk in Children
But how does this do it practically? Scholars collect a significant quantity of health data about a substantial number of children and train machine-learning platforms to identify the latent risk factors. As an example, Dr. Armour and his team at the Children Hospital of Ottawa (CHEO) compiled a huge amount of data of 703,894 mother-baby health records in Ontario. This sample had more than 10,000 children who eventually developed ASD. Their AI model, a state of art deep learning transformer, was trained to study this data but was not informed of precisely what patterns to identify.
The AI was also tested on new cases after being trained on historical data. These findings were encouraging: the model had an approximate sensitivity of 71 percent of children who would develop ASD. In simple words, it was able to identify, half a decade beforehand, around 7 children out of 10 who were to be diagnosed with autism, in a proper way. This does not imply that AI presents a final diagnosis - not at all - but it is able to produce an enriched pool of kids at greater risk. (CHEO Research Institute)
Pediatricians can then monitor those children more conscientiously or can provide early support, instead of letting more serious symptoms manifest themselves.
Notably, this AI screening is a population-based one with privacy protection. All work was performed in excellent ethics and security regulations, and the computers only perceive coded data (no names or images). The Canadian health system is well-prepared to this: the country has abundant and standardized, inter-provincial data. With data on BORN Ontario, ICES and CIHI available, as CHEO researchers have pointed out, the AI is able to sort through 1.4 million cases to identify patterns that would not have been identified by a human eye.
According to Dr. Armour, AI is an influential instrument to study complicated associations within these huge data sets. With the health care data, particularly with the 1.4 million cases in our cohort, AI is capable of finding very slim differences. It is the sort of jump that creates hope again, an algorithm that functions as the second pair of eyes, baby records being scanned by it in search of those little footprints of autism danger.
CHEO’s AI Autism Prediction Study: How Canadian Hospitals Use Data to Identify ASD Early
In July 2025, CHEO made its first milestone: its scientists had mastered the ability of artificial intelligence to forecast the risk of autism. This was the initial large-scale research of this kind in North America. Results published by the team - comprising experts of both CHEO and Ottawa Hospital Research Institute - indicated that AI can, in fact, learn when health data are used, to identify children who are more likely to require ASD diagnosis in the future. They trained their model on Ontario integrated datasets (prenatal records, newborn screening outcomes, and hospital data) and ensured that it was able to identify risk indicators by the age of 5.
So what is the implication of this to families? Practically, the AI tool would be able to operate silently, by recording which small patients have similar medical histories to those who subsequently were diagnosed with autism.
Doctors may tell the parent, Let's keep an extra eye on this one when the profile of the child reaches a particular risk level. They will be able to offer resources or assessments sooner, then. This would save years of waiting to parents. The explanation of Christine Armour is simple: early diagnosis of ASD would enable us to foresee better what the needs are and what resources are needed to provide the necessary help to children and youth and their families.

The results of the CHEO study are sufficiently accurate in real-world applications, which is good considering it is the first attempt. Their combination model posted a reported sensitivity of about 70.9% and specificity of 56.9% or it identifies most true cases and false alarms at a distance. This is why they refer to it as a promising candidate of ASD screening in population. It should be more accurate over time, as the data and refinements will be improved (the team is already developing a follow-up project).
How Canadian Pediatric Hospitals Are Using AI for Early Autism Screening
CHEO’s work is leading the way, but it’s part of a bigger movement. Across Canada, pediatric hospitals and research centers are embracing AI in children’s health. For instance, Toronto’s Hospital for Sick Children (SickKids) has launched a program called AI in Medicine for Kids (AIM), which aims to “reimagine the future of pediatric care through automation, prediction and early detection.” Although SickKids’ AI projects range from detecting heart arrhythmias to predicting kidney issues, the same underlying approach applies: using data to spot trouble before symptoms scream for attention.
Even in fields not yet focused on autism, SickKids and others are building the infrastructure. As SickKids reports, their teams are using machine learning to streamline emergency-room tests and to foresee life-threatening events moments before they happen. These efforts train the next generation of data tools that could eventually analyze developmental data and videos, just as some research outside Canada is doing. The bottom line is that Canadian hospitals are preparing to use AI whenever it can safely improve care. (SickKids)
Building Trust in AI Autism Screening: How Families and Doctors Work Together
Naturally, the idea of AI ranks the questions: How can we ensure that it is used responsibly? Will the parents take the word of a computer? These issues are being thought over by Canadian researchers. The CHEO team in fact, focuses on family and professional input throughout each process. They have questioned parents: "Assuming we can create this [screening tool], what do you imagine will be useful to your family? They determine that the technology addresses issues of concern and they can earn the trust of the people.
Ethics and privacy are also pointed out in the communication in the project. One public podcast and news posts frequently have Dr. Armour saying that the team is adhering to the framework of responsible AI by CHEO, and they are also contemplating how to safeguard privacy and how to notify families about any risk discoveries. Indicatively, BORN Ontario clarifies how AI analysis of prenatal ultrasound data can indicate ASD risk but it always comes together with a reminder that it is doing it in a responsible manner This transparency - openly discussing the boundaries and protection of the technology - is gaining parents and clinicians confidence in doing so.
Future of AI-Based Autism Detection: Earlier Support and Better Outcomes for Children
What is the tangible positive impact on children and families then? It is hoped that such early warning signs are visited by earlier support services. Provided that AI can notify doctors when a baby is one or two years old, the therapies can be initiated months or years earlier than they would be with the previous model. Intervention at the age of 2 is likely to have a beneficial impact on the language and social skills of a child and even alter the course of their life.
The researchers will also extend their tools and share them. The next grant that CHEO will work on is the PILLAR project, which will introduce additional sources of data and will test the AI on more heterogeneous communities. They also see the doctors in Canada having access to such a risk calculator one day. At the same time, projects such as the 17.5 million AI-health coalition in Canada (with SickKids and others) are developing the data structures and models that would be used to support AI in several pediatric applications.
Artificial intelligence-powered screening could become a reality by the time the current toddlers get to school. At least, pilot projects help clinicians to understand how they can incorporate AI in a compassionate manner. This is what must be achieved: no child should be left behind because the manifestation of their specific symptoms was a bit later. According to Dr. Armour and colleagues, the application of AI on our high-quality health information is a potential path to universal ASD screening that would enable families to connect with each other in a faster way.
Why AI-Driven Autism Prediction Brings New Hope for Families in Canada
For parents wondering about autism risk, these developments bring real hope. The data shows that Canadian pediatric centers are applying expertise and new technology to support families. Researchers and doctors aren’t replacing the human touch – they’re enhancing it. AI becomes another tool for pediatricians, alongside their experience and compassion.
Thanks to collaborative efforts at places like CHEO and SickKids, a future arrives where spotting autism risk early is less a matter of luck and more a matter of smart science. That means children get the support they need during critical early years. As one researcher noted, AI doesn’t change the goal — it accelerates it: improving outcomes and quality of life for children on the autism spectrum and their families.
