Which of the following would NOT make a person eligible for a security guard license?

Having a previous criminal record for assault with a weapon under the Criminal Code of Canada indeed makes a person ineligible for a security guard license. This is because the role of a security guard requires a certain level of trustworthiness and integrity, which is compromised if the individual has a history of violent behavior or criminal activities. Authorities prioritize the safety and security of the public, and a record of serious offenses such as assault indicates a potential risk to that safety.

In contrast, having more than three speeding offenses within a year under the Highway Traffic Act, being 18 years of age, and being legally allowed to work in Canada do not disqualify a person from obtaining a security guard license. Speeding offenses, while possibly indicative of reckless behavior, are not considered as severe as a criminal record involving violence. Age and legal work status are general eligibility criteria that simply ensure the individual can comply with job requirements and responsibilities.
