About Polygraph Testing
A polygraph examination — commonly known as a lie detector test — is a psychophysiological assessment that measures involuntary physiological responses while a person answers a series of questions. Modern digital polygraph instruments simultaneously monitor five channels: thoracic respiration, abdominal respiration, electrodermal activity (skin conductance), cardiovascular activity (blood pressure and pulse), and peripheral vasomotor responses.
When administered by a qualified, APA & CPA-accredited examiner using validated protocols, polygraph testing achieves 90–95% accuracy in specific-issue testing — supported by decades of peer-reviewed research. The polygraph remains the only scientifically validated technology for truth verification; alternatives such as voice stress analysers, mobile apps, and eye-tracking tools have not been validated by independent research.
A typical examination takes 90 minutes to 2 hours. This includes a pre-test interview (30–45 minutes) where every question is discussed and agreed in advance, the polygraph examination itself where questions are repeated a minimum of three times for accuracy, and a post-test review. A detailed written report with methodology, results, and professional conclusions is provided on the same day.

Why Examiner Accreditation Matters
The accuracy of a polygraph examination depends almost entirely on the skill, training, and ethical standards of the examiner. An unqualified examiner can produce unreliable results that are worthless — or worse, harmful — in legal, personal, or professional contexts. Accreditation is the only way to ensure your examination meets professional standards.
American Polygraph Association
The gold standard. Requires APA-accredited training, strict ethical standards, and ongoing continuing education.
British Polygraph Society
UK's professional body. Rigorous training and ethical requirements aligned with European standards.
European Polygraph Association
Sets standards across Europe for methodology, training, and quality assurance in psychophysiological detection.
Red Flags: What to Avoid
No APA, BPS, or EPA affiliation means no verified training or ethical oversight.
Short or online-only courses don't meet APA standards. Legitimate training requires 400+ hours.
Voice stress analysers, apps, and eye-tracking are not scientifically validated.
Professional examiners always provide a detailed written report. Verbal-only results are a red flag.
Polygraph Admissibility in Manitoba
Polygraph results are generally inadmissible in Manitoba courts, consistent with the Supreme Court of Canada ruling in R. v. Béland (1987). Law enforcement agencies, including the RCMP and Winnipeg Police Service, may use polygraph examinations as investigative tools.
Workplace Polygraph Law
Manitoba does not have specific legislation governing workplace polygraph use. The Manitoba Human Rights Code and Personal Health Information Act (PHIA) provide the framework within which any employment-related testing must operate.
