ER visits for gambling disorders doubled after expanded online gambling market
Surge in Emergency Room Visits Linked to Ontario's Expanded Online Gambling Market
A recent investigation conducted by researchers at the University of Toronto reveals a startling trend: emergency department (ED) visits related to gambling disorders nearly doubled following the expansion of Ontario's online gambling landscape and the legalization of single-event sports betting.
The Market Shift
In a restricted environment April 2022, Ontario transitioned to a new model, becoming the first Canadian province to permit private corporations to operate within a regulated online gambling framework alongside the government's own platform.
Current Market Statistics (2024)
The scale of this expansion is illustrated in the table below:
| Metric | Detail |
|---|---|
| Private Operators | 43 Companies |
| Active Betting Sites | 83 Platforms |
| Total Wagers | $82.7 Billion CAD |
| User Base | 2.6 Million Accounts |
Study Methodology & Findings
Researchers tracked Ontarians across a vast age spectrum—from 10 to 105 years old—over a 14-year window to determine how the shift to private online gambling affected health outcomes.
The Data Pipeline
Key Statistics:
- Total Volume: 757 unique individuals accounted for 952 total ED visits where gambling disorders were a primary or contributing factor.
- Demographic Spikes: The increase was most pronounced among males.
- Males aged 10–29: above expected levels.
- Males aged 30–44: above expected levels.
- Co-occurring Issues: Over of these patients presented with heavy substance use or additional mental health conditions.
- Severity: Approximately of all visits resulted in full hospital admission.
The full study was published in The American Journal of Preventive Medicine.
Expert Analysis
The researchers emphasize that the targeting of young men through aggressive digital marketing is a primary driver of these trends.
"The concentration of the increase among younger males is particularly concerning given the rapid growth and promotion of online sports betting, which target this demographic," explains Ryan Forrest, a doctoral student at the Dalla Lana School of Public Health.
Forrest further notes that the damage extends beyond the individual, creating a ripple effect of harm across families and entire communities.
Validating the Evidence
The team had previously noted a spike in calls to ConnexOntario (the provincial addiction helpline). However, they acknowledge a potential bias:
- Helpline Data: Could be skewed by mandatory ads on betting sites promoting the helpline.
- ED Data: Provides "cleaner" evidence because hospitals are not advertised on gambling platforms.
Daniel Myran, an associate professor at the Temerty Faculty of Medicine and scientist at ICES, warns that the ER data is likely just the tip of the iceberg:
"Most people experiencing gambling problems will never seek care, so the concern is that the increases in emergency department visits... may be revealing much larger increases in gambling-related harm."
Future Implications & Policy
With Alberta following Ontario's lead in July 2026, and other provinces facing pressure to deregulate, Myran urges a cautious approach. He suggests that jurisdictions should not simply open the doors to private operators without rigorous protections.
Recommended Safeguards

The researchers conclude that the Ontario experience serves as a critical warning: the rapid expansion of private online gambling must be balanced with robust safeguards to prevent a public health crisis.
