Emergency department visits for gambling disorders nearly doubled after Ontario expanded its online gambling market

Emergency department visits for gambling‑related disorders have surged since Ontario opened its market to single‑event sports betting and broadened online gambling options, a new analysis by the Institute for Clinical Evaluative Sciences (ICES) shows. The study, which compared health‑system data before and after the regulatory changes, found that the number of ED presentations coded for gambling problems roughly doubled, with the most pronounced rise occurring among men aged 18‑34.

Researchers attribute the spike to increased accessibility and the appeal of rapid, high‑stakes wagering introduced by the single‑event betting model. While the overall incidence remains low relative to other emergency presentations, the upward trend signals a potential public‑health concern as the province expands its gambling infrastructure. Health officials and policymakers are urged to monitor the pattern and consider targeted prevention and treatment resources for the demographic most affected.
