Our Polygraph Services
We offer a full range of lie detector tests for personal, corporate, and legal needs — each examination focused on a single, clearly defined issue, which is the format research supports most strongly.

- Theft allegations
- Pre-marital concerns
Commercial / Corporate Testing
For employers and organizations conducting internal reviews, we work strictly within the legal limits that apply to workplace testing in each province, and only ever on a voluntary basis:

Confirm Your FormatLie Detector Tests Across Canada — Including the Northwest Territories
We run lie detector tests right across Canada, in every province and major city. Even where we don't have an office — including many remote regions and communities — a mobile examiner who travels to you means you can still be tested. Below is where we work and the kinds of matters we most often handle in each region.
Ontario
Our largest market, covering the Greater Toronto Area and the rest of the province. Most requests here involve private and personal matters, family and relationship disputes, and support for legal or defence cases.
Quebec
A strong bilingual market: examinations are available in English or French. We commonly handle private, legal, and business matters across the Montréal region and beyond.
British Columbia
Active demand across Greater Vancouver and Vancouver Island, mainly for private and family matters alongside business cases.
Alberta
A strong corporate market, with frequent internal investigations and insurance- or finance-related cases, alongside private testing.
Manitoba & Saskatchewan
Steady demand across the Prairies for private and legal matters.
Atlantic Canada
Full coverage across the Atlantic provinces for private and legal matters.
Northern Territories
No local offices, so we test by a mobile examiner who travels to you, or the nearest certified examiner — including remote Indigenous and rural communities, keeping our coverage truly nationwide.
How Your Lie Detector Test Is Conducted — In-Office or Mobile
We offer two ways to take a lie detector test, so distance is never the reason you can't get an answer. Whichever you choose, the examination follows the same structured process and the same standards — only the setting changes.
There may be no physical office near you in the Northwest Territories, but you can still be tested. We arrange a polygraph examination through a mobile examiner who travels to you, or the nearest certified examiner — whichever reaches you fastest while keeping the process private and properly conducted.
Why People Take a Lie Detector Test
People come to us for all sorts of reasons, but most situations fall into three groups.
Relationship & Trust
Suspected infidelity, a need to rebuild trust after a breach, or a wish for objective evidence in a personal dispute. A test can replace circular arguments with a documented, third-party result.
Workplace & Theft
Suspected staff theft, internal misconduct, or corporate compliance concerns where an employer or employee wants an impartial assessment of a specific allegation.
Legal & False Accusations
Support for a defence, a response to a false accusation, custody-related disputes, or documentation a lawyer can use as part of a broader case strategy.
What Is a Lie Detector Test?
A lie detector test, properly called a polygraph examination, is a psychophysiological assessment. It records the small, involuntary physiological reactions that occur while a person answers a structured set of questions, then analyzes those patterns to evaluate truthfulness on a specific issue.
What a Polygraph Measures
A modern examination tracks several physiological channels at once:
Thoracic respiration — breathing movement in the chest.
Abdominal respiration — breathing movement in the diaphragm and abdomen.
Electrodermal activity — changes in skin conductance (sweat-gland response).
Cardiovascular activity — relative blood pressure and pulse changes.
Peripheral vasomotor response — blood-flow changes in the fingertips.
Today's computerized instruments record all of these channels simultaneously, producing a synchronized set of charts for the examiner to score.
How a Lie Detector Test Works
A polygraph examination follows a clear, repeatable sequence. Knowing each stage in advance helps you arrive prepared and reduces uncertainty on the day.
Correspondence & Suitability
You begin by submitting the appointment request form. We ask about the situation and relevant medical history, confirm that you are suitable to be examined, and agree on the exact wording of every question before anything is scheduled. Nothing is asked during the test that you have not seen and approved.
Pre-Test Interview
On the day, you review and sign a consent form, then discuss the situation in detail with your examiner. You go through each question word for word, and the examiner explains how the instrument works so you feel settled before recording begins.
The Examination
The examiner connects you to the instrument and records your physiological reactions as you answer. Each relevant question is repeated at least three times across the charts, because consistency across repetitions is what makes the result reliable.
Analysis & Written Results
The examiner scores the charts and reaches one of three conclusions: NDI (no deception indicated / truthful), DI (deception indicated), or INC (inconclusive). You receive a detailed written report. If a result is inconclusive, our policy includes one complimentary retest under the stated conditions.
A typical examination takes between 90 minutes and 2.5 hours, depending on the number of issues and the complexity of the case.
Lie Detector Test Accuracy
Accuracy depends heavily on the examiner's technique and the test format. The figures below reflect single-issue testing under proper conditions.

An honest note on accuracy:
These figures are research-supported in single-issue testing, not absolute guarantees. No examiner can promise "100% accuracy," and any provider who does is overstating what the method can do. A polygraph is a strong, structured tool that works best on one clearly defined issue — and that is exactly how we use it.

Our Certified Examiners
The accuracy of any examination depends almost entirely on the training, qualifications, and ethics of the person running it. Our examiners are certified, work to recognized international standards, and use validated, industry-standard computerized polygraph instruments.
American Polygraph Association (APA)
The APA sets a widely recognized international benchmark for accredited training and ethical standards in the field.
Canadian Professional Standards
In Canada, recognized professional bodies — such as the Canadian Association of Police Polygraphists (CAPP) — reflect the training and ethics expected of examiners working in this country, and Canadian examiners typically follow APA-aligned methodology.
European Polygraph Association (EPA)
The EPA contributes to methodology and quality standards recognized internationally among practitioners.
How to Choose a Polygraph Examiner
The examiner matters far more than the machine. Be wary if you notice any of these red flags when searching for polygraph services.
No professional membership — no recognized affiliation such as APA, CAPP, or EPA.
Non-accredited or online-only training with no verifiable credentials.
Unvalidated 'technology' — voice-stress analyzers, phone apps, or eye-tracking marketed as lie detection.
'Over-the-phone' or same-day-only 'testing' offers, which are common scam formats.
Suspiciously cheap 'discount' polygraphs that undercut the real cost of a proper examination.
No detailed written report — verbal-only results with nothing documented.

Fill out the appointment request form.

Legal Admissibility & Regional Rules
Understanding where and how polygraph results can be used in Canada, from criminal courts to private workplaces.
Is a Lie Detector Test Admissible in Court?
Polygraph results are generally not accepted as direct evidence in Canadian criminal courts. The leading authority is the Supreme Court of Canada's decision in R. v. Béland (1987), which held polygraph evidence inadmissible because it conflicts with established rules of evidence. That said, polygraph testing is widely used as an investigative tool — by police services, in insurance matters, and in civil disputes — and remains valuable for private and corporate purposes. Testing is always voluntary: no one can be forced to take a polygraph.
Polygraph in the Workplace
Workplace rules differ by province. In Ontario, Part XVI of the Employment Standards Act, 2000 prohibits an employer from requiring, requesting, enabling, or influencing an employee or applicant to take a lie detector test. Alberta and British Columbia have no equivalent employment-standards ban, but their private-sector privacy laws (PIPA) and human-rights and common-law privacy protections still apply. In every province, voluntary testing remains lawful when the person genuinely consents.
Polygraph in the Northwest Territories
The Northwest Territories has no specific legislation on workplace polygraph testing. General human-rights protections and applicable privacy rules (including PIPEDA, in the commercial contexts it covers) provide the relevant framework, and any testing must be voluntary.

Frequently Asked Questions
Here are the questions we hear most often before an examination. If yours isn't covered, ask us through the form and we'll answer before you book.
How long does a lie detector test take?
Most examinations take between 90 minutes and 2.5 hours. Single-issue tests sit at the shorter end; multi-issue or screening sessions take longer.
How accurate is a lie detector test?
Single-issue testing is research-supported at roughly 85–90% accuracy under proper conditions. No examination is 100% accurate, and we never present it that way — accuracy depends on the examiner's skill and a clearly defined question.
Can nervousness affect the results?
Nervousness alone does not produce a 'deception indicated' result. The examiner establishes your baseline first, and scoring looks at reactions tied to specific relevant questions, not general anxiety.
Can I choose the questions that are asked?
Yes. You review and agree on every question during the pre-test stage. Nothing is asked that you have not seen and approved in advance.
Can someone be forced to take a polygraph test?
No. Polygraph testing is always voluntary, and you provide written consent before any examination begins.
Can someone 'beat' the polygraph?
Attempts to manipulate results do occur, and trained examiners are alert to them. A properly structured, professionally scored examination is designed to identify unreliable charts rather than be fooled by them.
How much does a lie detector test cost?
Pricing starts from $400 for a single-issue examination and rises with the number of issues and the complexity of the case. You receive a clear quote before booking, and your first consultation is free.
Can I take the test while pregnant or on medication?
Possibly — it depends on your circumstances. Tell us during the suitability stage so the examiner can assess whether testing is appropriate for you at this time.
Will a health condition (e.g. high blood pressure) affect the result?
Certain conditions can affect suitability. Disclose any relevant health information beforehand so the examiner can decide whether to proceed or adjust the approach.
Does a lie detector test hurt?
No. The sensors are attached externally and are non-invasive. The process is comfortable, with no needles and nothing under the skin.
Can someone accompany me during the examination?
A support person may attend the building with you, but the examination itself is conducted privately between you and the examiner to keep the recording clean.
How and when are results delivered?
You receive a detailed written report once the examiner has scored the charts, within the timeframe we confirm at booking.
