The Responsible Gambling (RG) Check patron surveys provide the largest dataset on awareness of RG among patrons of casinos and racinos in Canada. The researchers analyzed data collected from 2011–2019, which included 18,580 patrons from 75 venues. However, data from 2011 were not used because there were fewer respondents in 2011 than in later years. The results suggested increases in awareness of RG information and behaviour over time, especially among patrons who gambled regularly. However, 13.4% of patrons said they had not seen any RG information at the venue. Even though many patrons were aware of some aspect of RG, considerably fewer patrons reported RG behaviour (i.e., asking staff about an RG information centre and visiting it).
