Understanding the public health impact of gambling regulation requires systematic data on problem gambling prevalence — data that is expensive to collect rigorously, complex to interpret, and often subject to significant methodological debate. Canada has a relatively mature tradition of gambling prevalence research, with the Canadian Community Health Survey and various provincial-level surveys providing longitudinal data that can be analyzed against major policy changes such as the legalization of single-event sports betting and Ontario's launch of a competitive multi-operator iGaming market.
Measurement Tools and Methodological Considerations
The most widely used tool for measuring problem gambling severity in Canadian research is the Problem Gambling Severity Index (PGSI), a nine-item screening instrument developed in Canada and validated across multiple population samples. The PGSI categorizes respondents as non-problem gamblers, low-risk gamblers, moderate-risk gamblers, or problem gamblers based on their responses to questions about gambling-related financial, social, and emotional harms over the past 12 months.
Canadian prevalence surveys have historically reported problem gambling (PGSI score of 8 or higher) rates in the range of 0.4 to 1.0 percent of the adult population, with moderate-risk gambling (PGSI 3-7) rates of approximately 1.5 to 3.0 percent. These figures are consistent with comparable estimates from other regulated gambling jurisdictions including the UK, Australia, and Nordic countries, suggesting that Canada's regulatory frameworks have historically been associated with prevalence rates in the moderate range internationally.
Impact of Online Market Expansion
The central research question following Ontario's 2022 market opening is whether the expansion of regulated online gambling access — combined with the heavy marketing investment by competing operators — has changed problem gambling prevalence rates in the province. This question is methodologically difficult to answer because: (1) longitudinal survey data with pre- and post-liberalization observations takes years to accumulate; (2) problem gambling prevalence rates can change for reasons unrelated to market regulation; and (3) any observed increase in help-seeking or treatment utilization could reflect either more harm or more effective identification and response.
Preliminary data from CAMH (Centre for Addiction and Mental Health) and the Responsible Gambling Council's Canadian surveys indicates that online gambling participation has increased in Ontario since 2022, consistent with the market data showing growth in registered player accounts. Whether this increased participation is concentrated in the general population (low individual risk) or disproportionately among at-risk individuals is the key policy variable, and the data available as of mid-2024 does not yet provide a definitive answer.
ConnexOntario, the provincial helpline that includes problem gambling referral services, has reported increased call volumes related to online gambling since 2022, which could reflect either increased harm, increased awareness of available services, or both. Distinguishing between these interpretations requires comparison with control groups and longer observation periods than are currently available.
Self-Exclusion Program Participation
Ontario's iGaming market requires all registered operators to participate in the provincial self-exclusion system, which allows players to exclude themselves from all registered Ontario iGaming platforms through a single registration. The number of self-exclusions registered since the market launched has grown year-over-year, reaching over 30,000 cumulative registrations by early 2024 according to iGaming Ontario's disclosures.
Self-exclusion registration rates are a partial proxy for problem gambling engagement with available tools, though they systematically undercount the problem gambling population because many individuals with gambling problems do not seek formal intervention. The self-exclusion figures from Ontario are nonetheless encouraging as an indicator that the mandatory inclusion of self-exclusion in all registered operator platforms is reaching players who wish to use it — a significant improvement over the pre-2022 environment in which a player self-excluding from OLG's platform had no restriction on accessing offshore alternatives.
Provincial Comparison of Help-Seeking Rates
British Columbia's GameSense program, operated by BCLC at casino facilities and through an online platform, has been cited as a model for consumer-facing responsible gambling communications. BC maintains data on the utilization of GameSense advisors and online self-assessment tools, which provides a measure of help-seeking engagement that can be compared across provinces and over time.
Quebec's Jeu: aide et référence helpline data shows relatively stable call volumes in recent years, which Loto-Québec interprets as consistent with stable problem gambling prevalence under the monopoly model. Critics note that the absence of competitive market growth in Quebec makes it difficult to determine whether flat help-seeking rates reflect genuinely stable prevalence or simply the absence of the stimulus that an expanded online market creates.
Alberta's ARC (Alberta's Recovery Community) and the AGLC's player protection programs provide additional provincial data points. Alberta's per-capita problem gambling rates have historically been slightly above the national average, potentially reflecting the province's higher rate of gambling participation overall and the density of VLT locations in Alberta communities.
Responsible Gambling Funding Levels
CAMH receives approximately $50 million annually from Ontario's combined OLG and iGaming Ontario responsible gambling fund contributions for research, treatment programming, and the Problem Gambling Institute of Ontario (PGIO). This funding level is among the highest of any provincial responsible gambling program in Canada in absolute terms, though Ontario's population size means per-capita funding is comparable to, rather than clearly superior to, comparable provincial programs.
The Responsible Gambling Council (RGC), which operates nationally and provides the RG Check certification program for gambling venues and platforms, reports that its assessment pipeline has grown substantially since Ontario's market expansion, as new iGaming Ontario operators seek RG Check certification to demonstrate compliance with industry responsible gambling standards. As of 2024, over 40 Ontario-registered operators had engaged with the RGC's assessment process.
Research Priorities for 2024-25
Regulatory and research bodies have identified several priority areas for problem gambling research in the 2024-25 period. These include: longitudinal studies tracking problem gambling prevalence in Ontario pre- and post-iGaming market launch; research on the specific responsible gambling effectiveness of Ontario's mandatory deposit limit and self-exclusion systems; and comparative studies examining whether the competitive market's higher marketing investment is associated with measurable changes in gambling attitudes among non-gamblers, a potential leading indicator of future prevalence changes.
The federal government's Public Health Agency of Canada has indicated interest in supporting national-level surveillance of gambling-related harms as part of its broader substance use and addictions monitoring framework, which could provide more consistent and comparable data across provinces than the current patchwork of provincial surveys with varying methodologies and timing.
