Admission standards or specific child:guardian ratios for public pools have been endorsed and promoted by the Ontario Ministry of Health and Long Term Care (MOHLTC) to prevent recreational water injuries and fatalities. However, the voluntary adoption of these admission standards in Ontario has not been evaluated. Therefore, the aim of this study was to explore the implementation of these admission standards in Class A public pools. An online survey was developed and disseminated to Class A public pool operators in Ontario. Frequency distributions were used to describe the results. All respondents have some form of admission standards integrated into their operations, with 68% using child:parent ratios that exceed the minimum MOHLTC's recommendations. The majority of operators (87%) felt that admission standards have a positive impact and there were no known increases in water-related incidents post-implementation. Many owners/operators (78%) would support their enactment into the pool regulations. The findings from this study highlight the promise of utilizing admission standards to prevent or, at the least reduce, the burden of injury related to recreational water use in Ontario. While the results are encouraging, it is recommended that further research be conducted as this was an exploratory study only.
