Our staff are the driving force behind our success. We recruit and assign personnel who are exceptionally motivated to manage day-to-day security operations as well as crisis situations. Our highly qualified personnel are capable of performing a variety of tasks and managing complex issues, and roles and responsibilities often extend far beyond established security and policing duties.
In many cases, their past military or RCMP service provides them with well-developed skills and knowledge that enhances the execution of their day-to-day duties. Our personnel are service-oriented, dedicated and professional.
They possess an unmatched work ethic, are exceedingly loyal and they bring the highest degree of discipline and maturity to each assignment. We are committed to the highest standards of training, which includes the Commissionaires Security Guard Course and Supervisor Program, both of which meet Canadian General Standards Board Criteria and the Alberta Security Services Act. On-going specialized training courses also ensure our personnel not only maintain but improve the essential skills needed to manage any workplace challenge.
