ER visits for gambling rise in Ontario since expansion of online betting: study
TORONTO — A new study suggests emergency department visits for gambling disorders have doubled in Ontario since the expansion of online gambling and legalization of single-event sports betting a few years ago.
The Institute for Clinical Evaluative Sciences says it analyzed data from January 2012 to September 2025 and found an increase in gambling-related emergency department visits among boys and men between the ages of 10 to 44.
The researchers examined a total of 952 emergency department visits for gambling disorders made by 757 individuals during the study period and noted an overall increase of 99 per cent than what was expected before the relaxation of gambling rules.
The study found that by the end of the study period, the number of gambling-related ER visits was 154 per cent higher than expected among males aged 10 to 29, and 116 per cent higher among males aged 30 to 44.
