In this study, the researchers looked at how the number of contacts made to Ontario’s gambling helpline might have changed following policy changes that expanded the online gambling market in the province. They used data from people who contacted ConnexOntario with gambling-related concerns between January 2012 and September 2025. Gambling-related contacts to ConnexOntario increased by about 95% following the launch of the government-run online gambling platform (PlayOLG) in 2015 and expansion to allow private companies to offer online gambling, including sports betting, in 2022. The largest increases were seen among adolescent boys and men between 15 and 44 years old. These findings suggest that the expansion of online gambling in Ontario is related to increased problem gambling, help-seeking, or both.
