The purpose of the study was to determine whether the presence of a new Canadian casino increased the rate at which criminally inadmissible persons sought entry to Canada. The impact of the casino was assessed by looking at trends in total bridge crossings before and after the opening of the casino, trends in the total number of criminals denied entry to Canada, and trends in the proportion of criminals who had convictions for offenses related to organized crime. Results showed the rate of denials of entry to Canada on grounds of criminal inadmissibility rose faster than border traffic in general, but there was a decline in the proportion of those with prior records for organized crime-related offenses. The authors conclude casinos may attract a disproportionate number of individuals who have low self-control and criminals may fall into this category. They note an important contribution of the study is the provision of systematic information to Canadian immigration officials about trends in the number of criminally inadmissible persons seeking admission to Canada and the precise points of entry most frequently used by these persons. 19 references and 3 figures
