Security Investigators play a vital role in protecting Department of National Defence assets, personnel, and sensitive information. As a Security Investigator, you will conduct thorough background investigations, security clearance assessments, and inquiries related to personnel security matters. Your work helps maintain the integrity and trustworthiness of the DND civilian workforce and supports national security objectives.
Your day-to-day responsibilities include interviewing witnesses and subjects, reviewing documentation, analyzing investigative findings, and preparing detailed reports. You will work with various government agencies, law enforcement partners, and international security organizations. Security Investigators must exercise sound judgment, maintain confidentiality, and follow strict security protocols while gathering and handling sensitive information.
You will work in a professional office environment, with occasional travel required for interviews and investigations. This role demands attention to detail, strong interpersonal skills, and the ability to work independently while meeting tight deadlines. Most positions are located in major Canadian cities with DND facilities, though some flexibility may exist depending on operational needs.

Training
To qualify as a Security Investigator, you typically need a secondary school diploma or equivalent. Many successful candidates hold a post-secondary credential such as a college diploma or university degree in criminal justice, security studies, public administration, or a related field. These educational backgrounds provide valuable foundational knowledge in investigative procedures and security principles.
Once hired, you will receive comprehensive on-the-job training covering investigative techniques, interview methods, security legislation, and DND-specific policies. You may be required to obtain or maintain a Top Secret security clearance, depending on the specific position. The department offers professional development opportunities including courses in investigation methodologies, report writing, interviewing techniques, and security management. Some positions may require or support certifications through recognized security or investigation associations.
Entry Plans
Entry into the Security Investigator career stream typically occurs through public competitions advertised on the Public Service Commission (PSC) website and the Government of Canada Job Bank. DND regularly posts Security Investigator positions at various experience levels, from entry-level to more senior roles.
You may also enter this career through lateral moves if you currently work in related DND civilian positions, such as security or administrative roles. The department occasionally operates recruitment pools for Security Investigators to fill multiple positions efficiently. Students and recent graduates should monitor PSC postings for bridging programs or student employment opportunities that could lead to permanent positions.
To be considered, you must be a Canadian citizen, pass a security clearance process, and meet the specific education and experience requirements outlined in each competition. Some competitions may include written assessments, interviews, and reference checks as part of the selection process.
Part-Time Options
Part-time and flexible work arrangements for Security Investigators are typically limited due to the investigative nature of the work and security clearance requirements. Most positions are full-time, as investigations require continuity and sustained commitment to case management.
However, DND is committed to supporting work-life balance where operationally feasible. Remote work options may be available for specific administrative or report-writing tasks, though investigative activities such as interviews and site visits must occur on-site. Flexible scheduling arrangements may be negotiable on a case-by-case basis, subject to operational requirements and management approval.
When considering this career, discuss specific flexible work options during the recruitment process or with your manager after hire. The security-sensitive nature of this role means arrangements must maintain investigative integrity and protect classified information.
