The finding comes from a comprehensive survey conducted by the CAMH last year and published Monday.

“Taken together, about one-in-eight (12%) students report any type of online gambling (online sports betting, online poker, online casino games) at least once in the past year,” the CAMH’s Ontario Student Drug Use and Health Survey also noted.

That figure is a sharp increase from the last survey the CAMH conducted two years ago, where it reported that 8% of students reported any online gambling.

The report also noted that the percentage of students reporting online sports betting in the past year has “significantly increased” since 2017, the first year it began monitoring the issue, jumping from 1% to 10% in 2025.

Almost a quarter (23%) of students reported seeing or hearing advertising for online gambling sites daily.

Expert urges ‘stronger measures to reduce youth exposure’

“The rapid growth of online gambling among young people is really concerning,” said Dr. Peter Selby, principal investigator of CAMH’s INTREPID Lab, in a press release.

“The results raise important questions about how young people are able to access gambling products despite age restrictions, and about the influence that widespread gambling advertising and its normalization have on attitudes and behaviours,” said Selby, who is also a senior scientist and senior medical consultant at CAMH, and an expert in youth mental health and substance use.

“We need stronger measures to reduce youth exposure during a vulnerable time of brain development and better prevent the long-term impact of these trends,” Selby added.
