All applicants must be a minimum of three years clear of any detected or undetected criminal activity. This includes past drug use. Our selection process is very thorough and includes several in-depth interviews, a polygraph examination and a background security investigation. It does not include a drug test. However, one of the criteria we evaluate candidates on is life experience. If you disclose any illegal activity, we will discuss it with you and determine whether it will preclude you from becoming a police officer with the Calgary Police Service. Complete disclosure throughout the recruiting process is crucial to a successful application.
