BDC Study Finds Higher ADHD Prevalence Among Canadian Entrepreneurs
New research from the Business Development Bank of Canada indicates that ADHD symptoms or diagnoses are present in up to one-quarter of Canadian entrepreneurs, with much higher rates among younger business owners.

A new study by the Business Development Bank of Canada (BDC), published in November 2025, reveals a higher prevalence of Attention Deficit Hyperactivity Disorder (ADHD) among Canadian entrepreneurs than previously understood.
The survey, which polled 1,463 entrepreneurs, asked about ADHD diagnoses and symptoms. Results showed that 7% of Canadian entrepreneurs had received a professional ADHD diagnosis. When including those with ADHD-related symptoms but without a formal diagnosis, the figure rose significantly to nearly one-quarter (24.8%) of all respondents.
The research identified a notable age disparity. A substantial 44% of entrepreneurs under 45 years old reported experiencing ADHD symptoms, compared to only 13% of those over 45. BDC suggests this difference may reflect lower diagnostic rates among older generations due to less awareness of ADHD in their formative years.
Indigenous entrepreneurs showed a particularly high prevalence, with 14% having received a formal ADHD diagnosis, and that number climbing to 38% when including those with symptoms. No significant gender differences in ADHD prevalence were observed in the study.
