We don't necessarily have any studies that could indicate, at the time of enrolment, who should or should not enlist in the Canadian Forces, who is more at risk. No such studies have been done. We know that recruiting centres do not test candidates for various factors, such as drug addictions. The same is true for alcohol abuse and various personality traits. Recruiting centres admit a broad range of people; however, some screening could be done there in order to retain the ideal candidates. Currently, we would need to conduct studies in this regard, in order not to discriminate against individuals who wish to enlist in the Canadian Forces.
