Canadian federal agencies like the RCMP and CSIS use polygraph in vetting, and this guide explains how the lie detector test fits into government screening north of the border.
A comprehensive examination of how the RCMP, CSIS, CSE, Canadian Armed Forces, and police services across Canada use polygraph testing for pre-employment screening, criminal investigations, and national security clearances. From the landmark R. v. Béland ruling to the 2024 NSIRA watchdog review, this guide covers every aspect of polygraph use in Canada.
TL;DR — The Short Version
- Polygraph results are inadmissible in Canadian criminal courts under R. v. Béland (1987), but confessions made during polygraph sessions may be admissible under R. v. Oickle (2000).
- Every RCMP Regular Member applicant must pass a Pre-Employment Polygraph (PEP) as part of the multi-stage hiring process.
- All CSIS employees undergo polygraph testing at hiring and every five years during clearance renewals.
- CSE has administered polygraph examinations to employees hired since January 2006 who require top-secret clearance, with the overwhelming majority of employees subject to testing.
- The Canadian Armed Forces uses polygraph for both security clearance screening and criminal investigations through the CFNIS Polygraph Section.
- A 2014 Treasury Board Standard requires polygraph for Enhanced Top Secret clearances; the RCMP's non-compliance drew scrutiny after the Cameron Ortis case.
- The Canadian Police College in Ottawa is the primary training centre, accredited by the APA and recognized by both CAPP and AAPP.
- A 2024 NSIRA watchdog report raised concerns about CSE's polygraph practices, though both CSE and Treasury Board defended the tool as an important security measure.

Polygraph in Correctional & Parole Contexts
Sex Offender Management and Risk Assessment
In the correctional and parole context, polygraph testing intersects with actuarial risk assessment tools used across Canada. The Static-99R, the most widely used sexual recidivism risk assessment instrument in the world, has specific coding rules regarding polygraph-derived information [25]Verified Static-99R Coding Rules Revised — 2016
Confirms that polygraph-derived information is normally excluded from Static-99R scoring and the rationale for exclusion. The coding rules explicitly state that evaluators may use any credible information to score victim items "except polygraph examination" [25]Verified Static-99R Coding Rules Revised — 2016
Confirms that polygraph-derived information is normally excluded from Static-99R scoring and the rationale for exclusion.
Information derived solely from polygraph interviews or examinations is normally not used to score Static-99R because such information was not used in the development and validation of the instrument [25]Verified Static-99R Coding Rules Revised — 2016
Confirms that polygraph-derived information is normally excluded from Static-99R scoring and the rationale for exclusion. The coding rules further specify that where an admission is initially made during a polygraph examination — including during pre-polygraph interviews, post-polygraph interviews, or after testing deceptive — it would normally not be counted, regardless of whether it was subsequently repeated in treatment or interviews [25]Verified Static-99R Coding Rules Revised — 2016
Confirms that polygraph-derived information is normally excluded from Static-99R scoring and the rationale for exclusion. This reflects the careful calibration of how polygraph-derived disclosures are handled in Canadian correctional practice.

The Value of Polygraph Testing in Canada's Security Framework
Supporting Arguments
Polygraph testing plays a vital role in Canada's multi-layered security framework. The Treasury Board has affirmed the polygraph's "proven record of uncovering adverse information" in security screening [16]Verified CSE should make changes or stop using polygraphs: watchdog report
Confirms NSIRA findings on CSE polygraph practices, Charter concerns, and CSE/Treasury Board defence of continued use. CSIS has stated confidence in polygraph as part of its "robust internal security measures" to protect information that is "highly sought and strategically invaluable in the hands of Canada's adversaries" [10]Verified Federal government rethinking use of controversial polygraph test
Confirms CSIS's defence of polygraph as element of security measures and Treasury Board review of 2014 Standard.
The Cameron Ortis case powerfully demonstrated the real-world consequences when polygraph screening is absent from the security clearance process. As intelligence specialist Professor Wesley Wark noted, the RCMP's failure to polygraph employees with Enhanced Top Secret clearances created a critical gap that undermined the entire national security screening framework [8]Verified RCMP Shuns Lie Detector Tests For Top Security Clearances Despite Federal Rules
Confirms CSE polygraph since January 2006, RCMP non-compliance with 2014 standard, and Wesley Wark's criticism. The case served as a catalyst for strengthening security screening across government.
For pre-employment screening, the polygraph provides a unique capability to detect concealed information that background checks, interviews, and references may miss. International research confirms that approximately 25% of law enforcement applicants are rejected based on information uncovered specifically through polygraph examination [5]Verified A national survey of practices, policies and evaluative comments on the use of pre-employment polygraph screening in police agencies in the United States
Confirms that 62% of large U.S. police agencies use pre-employment polygraph screening, rejecting approximately 25% of applicants. The Treasury Board has specifically noted that the 2014 Standard "constituted a substantial improvement in consistency, transparency, and accountability" [24]Verified Response to NSIRA's review of CSE's use of the polygraph for security screening
Confirms CSE and Treasury Board's official response defending polygraph use and commitment to quality improvements.
Ongoing Debates and Considerations
Despite its widespread institutional use, polygraph testing in Canada remains subject to healthy debate and evolving oversight. The 2024 NSIRA review of CSE's polygraph practices raised important questions about privacy protections, examiner conduct, and the appropriate weight given to polygraph results in screening decisions [16]Verified CSE should make changes or stop using polygraphs: watchdog report
Confirms NSIRA findings on CSE polygraph practices, Charter concerns, and CSE/Treasury Board defence of continued use. NSIRA found instances of "repetitive and aggressive" questioning by examiners and recommended that the Treasury Board urgently remedy identified issues [16]Verified CSE should make changes or stop using polygraphs: watchdog report
Confirms NSIRA findings on CSE polygraph practices, Charter concerns, and CSE/Treasury Board defence of continued use.
These concerns are constructive for the profession. CSE acknowledged the findings and committed to implementing improved practices to ensure quality control of polygraph exams [16]Verified CSE should make changes or stop using polygraphs: watchdog report
Confirms NSIRA findings on CSE polygraph practices, Charter concerns, and CSE/Treasury Board defence of continued use. Such institutional accountability strengthens the overall credibility of polygraph programs and benefits both examiners and examinees.
Research continues to advance the science. Studies examining the relationship between cardiovascular arousal and polygraph testing are refining our understanding of physiological responses, while research into symptomatic questions and irrelevant questions in polygraph testing continues to improve test protocols. The work of researchers like Honts and Crawford (2010) on polygraph countermeasures highlights the importance of proper training and the need to protect innocent examinees from false positive risks [14]Verified Polygraph countermeasures cannot be detected from respiratory signatures: Government policy puts the innocent at risk
Demonstrates that polygraph examiners cannot reliably detect countermeasures from respiratory patterns, highlighting importance of examiner training. The international dimension of polygraph policy development is also explored by scholars like Chekunov, Shapoval, and Belykh-Silaev (2022), who have examined the psychological, organizational, and legal aspects of polygraph use for evaluating reliability of candidates to security and defence agencies Verified Psychological, Organizational and Legal Aspects of the Use of Polygraph for the Evaluation of Reliability of Candidates to Security, Defense and Law Enforcement Agencies

Frequently Asked Questions
Are polygraph results admissible as evidence in Canadian criminal courts?
No. The Supreme Court of Canada ruled in R. v. Béland and Phillips (1987) that polygraph results are inadmissible in criminal proceedings. However, confessions or admissions made during or after a polygraph session may be admissible if they meet the standard tests for voluntariness, as established in R. v. Oickle (2000). The distinction is critical: the chart data cannot be shown to a jury, but what you say during the examination can be used against you.
Is it mandatory to take a polygraph when applying to the RCMP?
Yes. Every applicant seeking to become an RCMP Regular Member must undergo a Pre-Employment Polygraph (PEP) examination as part of the multi-stage selection process. The polygraph is one component of a comprehensive screening framework that also includes suitability interviews, psychological assessments, medical screenings, and background checks. Refusal to complete the polygraph will result in disqualification from the recruitment process.
How often does CSIS require polygraph testing for employees?
CSIS requires polygraph testing at two points: during the initial hiring process and every five years as part of mandatory security clearance renewals. All CSIS employees must undergo the test, regardless of their role, and even candidates who already hold security clearances from other government departments must complete CSIS's own full screening process including the polygraph.
Can a police officer force me to take a polygraph during a criminal investigation?
No. Taking a polygraph during a criminal investigation in Canada is always voluntary. Police cannot compel any individual — suspect, witness, or complainant — to submit to a polygraph. You have the right to decline, and legal aid organizations have publicly advised individuals to carefully consider such requests. If you are asked to take a polygraph in an investigation, you may wish to consult with a lawyer first.
Why didn't the RCMP polygraph Cameron Ortis before giving him top-secret clearance?
Despite a 2014 Treasury Board Standard requiring polygraph testing for Enhanced Top Secret clearances, the RCMP had not implemented the polygraph requirement for its security clearance process. The RCMP confirmed it had neither complied with the standard nor sought formal Treasury Board approval to waive it. This gap was exposed after Ortis's arrest in 2019 and became a major point of criticism from intelligence specialists. Ortis was subsequently sentenced to 14 years in prison in February 2024 for violating Canada's Security of Information Act.
Where can I train to become a polygraph examiner in Canada?
The primary training institution is the Canadian Police College (CPC) in Ottawa, which is accredited by the American Polygraph Association (APA) and recognized by both CAPP and AAPP. The CPC's Polygraph Examiners Course is offered to experienced investigators employed by recognized police, military, or intelligence agencies with established polygraph programs. The certification phase includes approximately nine months of practical application under indirect supervision. Our complete guide covers all the details for aspiring examiners.
Does CSE require polygraph testing for all employees?
The overwhelming majority of CSE employees are subject to polygraph testing. CSE administers polygraph examinations to employees hired since January 2006 who need top-secret clearance or a five-year update. Additionally, certain designated CSE positions require polygraph testing regardless of when the employee was hired. The entire screening and clearance process typically takes 12 to 18 months. Candidates must also abstain from illegal drug use for at least one year before applying.
What did the 2024 NSIRA watchdog report say about polygraph testing at CSE?
The September 2024 NSIRA report found that CSE's use of polygraph raised Charter concerns, including insufficient privacy protections and instances of repetitive or aggressive questioning. However, both CSE and Treasury Board strongly defended continued use of polygraph testing. The Treasury Board stated that the polygraph's proper use is consistent with Canadian law and values, and CSE committed to implementing improved quality control practices while continuing to use the technology as an important security screening measure.
Can military members refuse a polygraph when seconded to CSIS or CSE?
Yes. Under Canadian Armed Forces Military Personnel Instruction 01/13, CAF members who refuse to provide informed consent for a polygraph must stop processing for the targeted employment position. However, no adverse inference, administrative, or career actions may be taken against a CAF member who refuses or voluntarily withdraws consent. The policy emphasizes that CAF members must be fully informed of their rights before undergoing any polygraph examination.
