Demographics and Diagnosis

In Canada, boys are three times more likely to be diagnosed with ADHD than girls
The average age of diagnosis for ADHD in Canada is 7 years old
ADHD is often underdiagnosed in Indigenous communities across Canada
The average delay between onset of symptoms and diagnosis in Canada is approximately 3 years

Demographics and Diagnosis Interpretation

These statistics reveal that while Canadian boys are thrice as likely to be diagnosed with ADHD by age seven, marginalized communities often face a longer wait—highlighting a pressing need for equitable and timely recognition of this complex condition before missed opportunities for support become the true diagnosis.
