Ontario Student Survey Shows Mixed Trends in Youth Mental Health and Substance Use

However, girls and non-binary youth continued to report higher rates of emotional difficulties than their male peers

The Centre for Addiction and Mental Health released findings from the 2025 Ontario Student Drug Use and Health Survey on August 24, 2026, revealing that middle and high school students across the province have shown signs of recovery from pandemic-era mental health struggles, though substance use patterns remain a concern for certain groups. The survey, which collected data from over 10,000 students in grades 7 through 12, indicates a decline in reports of severe psychological distress compared to peak pandemic years, yet highlights persistent challenges related to anxiety, depression, and screen time, alongside varying trends in alcohol, cannabis, and vaping use among different age and demographic subgroups. Mental Health Indicators Show Gradual Improvement Students reported lower levels of suicidal ideation and self-harm behaviors in 2025 compared to 2021 and 2022, with 18 percent indicating serious psychological distress, down from 24 percent during the height of pandemic disruptions.

However, girls and non-binary youth continued to report higher rates of emotional difficulties than their male peers, suggesting ongoing disparities in mental health support access and outcomes. How Are Substance Use Patterns Changing Among Teens? Alcohol use remained stable, with about 40 percent of students reporting consumption in the past year, while cannabis use saw a slight decline among younger adolescents but held steady among older students. Vaping nicotine showed a modest decrease overall, though flavored product use remained popular, particularly among those who also reported using cannabis or experiencing high stress levels. Frequently Asked Questions What is the OSDUHS and why does it matter? The Ontario Student Drug Use and Health Survey is a long-running provincial study that tracks health behaviors, mental health, and substance use among students in grades 7 to 12, providing critical data for public health planning and school-based interventions.

Why did mental health indicators improve in 2025? Researchers suggest the improvement reflects a return to more stable school routines, increased access to counseling services, and reduced social isolation compared to the peak pandemic years, though systemic challenges remain. Are there any groups still at higher risk? Yes, female and non-binary students, as well as those identifying as LGBTQ2S+, continue to report elevated levels of anxiety, depression, and suicidal thoughts, highlighting the need for targeted support programs in schools and communities.
