The Centre for Addiction and Mental Health (CAMH) has reported a decrease in psychological distress among Ontario youth since the onset of the pandemic, although the levels remain high. According to CAMH’s recent Ontario Student Drug Use and Health Survey, 46% of students in Grades 7 to 12 indicated experiencing a “moderate to serious level” of psychological distress in 2025. This is a decrease from 51% in 2023.
Lead investigator Hayley Hamilton expressed optimism about the decline but noted that the current percentage of students facing mental health challenges is notably higher than over a decade ago. Factors such as social media influence and reduced stigma around mental health discussions may have contributed to the rising awareness of psychological distress among students.
CAMH observed a positive trend in students accessing mental health services within school settings, indicating a proactive approach to addressing youth mental health needs. Hamilton highlighted the significant efforts directed towards supporting young individuals through their mental health struggles amid various challenges.
Furthermore, the survey highlighted shifts in substance use behaviors among students, showing a decrease in alcohol and drug consumption over time. However, there was a concerning surge in online gambling activities, with one in 10 students reported engaging in sports betting in 2025, compared to one in 100 in 2017.
Hamilton, the co-director of CAMH’s Institute for Mental Health Policy Research, linked the increase in online gambling to regulatory changes in Ontario allowing private betting sites. Despite age restrictions, students have found ways to participate in online gambling activities, reflecting the need for continued monitoring and support in this area.
The 2025 Ontario Student Drug Use and Health Survey surveyed 11,108 students in Grades 7 to 12 across 42 school boards, providing valuable insights into youth behaviors and mental health trends. Conducted biennially since 1977, the survey serves as a crucial tool in understanding and addressing the evolving mental health landscape among Ontario’s youth.
