ER Visits for Gambling Rise in Ontario Since Expansion of Online Betting: Study

Researchers logged 952 gambling-related emergency visits over 14 years, with men and boys making up 72% of cases.

  • A new study published Wednesday in The American Journal of Preventive Medicine links Ontario's online gambling expansion to a spike in emergency department visits for gambling disorders, with the largest increases among males aged 10 to 29.
  • In April 2022, Ontario permitted private companies to operate online gambling sites, rapidly expanding the market to over 80 websites that generated $82.7 billion in wagers during 2024-25.
  • Analysis by ICES of 952 emergency department visits showed a 99 per cent overall increase compared to pre-liberalization levels, with males aged 10 to 29 experiencing a 154 per cent surge in admissions.
  • Patients presenting to emergency departments often had suicide risk and substance use alongside gambling addiction, prompting Dr. Daniel Myran, University of Toronto associate professor, to warn of a "public-health crisis."
  • Experts urge policymakers in other provinces like Alberta to monitor Ontario's data as they consider gambling liberalization, describing the province as a "natural experiment" for evaluating public-health effects.
