A friend borrows a significant sum and promises to return it after a contract clears. A relative takes a deposit for a car that never arrives. Two people split the cost of a renovation and later disagree about who paid what. None of it was written down, because writing it down would have implied distrust. Months later the money is gone, the relationship is damaged, and there is nothing to bring to a lawyer except two conflicting accounts of the same conversation.
Why these disputes are so hard to close
Civil action needs documents, and informal agreements rarely produce any. Bank transfers show that money moved but not what it was for. Messages are usually ambiguous, because people discuss money in person and confirm it with a sentence like “sorted, thanks”. Distance makes everything slower: one party is in another province, visits are rare, and each conversation restarts the argument from the beginning.
There is also a social cost that keeps people stuck. Pursuing a cousin or a long standing friend through the courts over a sum that is painful but not enormous feels disproportionate, so the dispute simply stays open for years. A polygraph examination is often chosen at exactly this point, not as a legal weapon but as a way to establish which version of events holds up.
Turning a dispute into testable statements
| Works as a test topic | Does not work |
| Did you receive a cash payment of a stated amount in a stated month | Do you intend to pay me back |
| Was the money described as a loan at the time it was handed over | Was it fair to keep it |
| Did you pass the funds to a third party | Are you financially responsible |
| Did you spend the deposit on something other than the agreed purchase | Did you mean well |
| Was there a second agreement that was not disclosed | Who was more reasonable in the argument |
The pattern is consistent: a single named action, a defined window of time, and an answer that can only be affirmative or negative. Intentions, fairness and character are outside the method entirely. A useful side effect of this discipline is that it forces both parties to name specific events, and some disagreements dissolve at that stage because the facts turn out not to be in dispute at all.
Why both sides often take the test
When only one person is asked to be examined, the proposal reads as an accusation and the conversation usually ends there. When both parties agree to the same topic list, the framing changes completely. Instead of “prove you did not take it”, the exercise becomes “let us take credibility out of this and look at the numbers”.
In practice this symmetry does three things. It removes the insult of being singled out, it shortens the list of contested points very quickly, and it produces something concrete to negotiate with, which matters when the realistic outcome is a repayment schedule rather than a court judgment.
How a session is structured
- Consent and topic. Signed in advance, with excluded subjects listed explicitly
- Pre-test interview, 30 to 40 minutes. Each question is read out and reworded until both sides understand it identically
- Recording, 40 to 60 minutes. Breathing, electrodermal activity, cardiovascular response and movement are tracked across several presentations
- Result. Explained the same day, with a written report available where a dispute may continue
Formats and costs in Canada
| Format | Price | Typical use |
| Standard examination, one person, one topic | C$760 | Most private money disputes |
| Online format session | C$285 | Preparatory and remote work |
| Testing in a language other than the working language | +C$130 | Multilingual households and partners |
| Multi topic or corporate examination | Quoted individually | Several separate episodes |
Each additional episode is effectively a separate examination with its own preparation and its own presentations, which is why multi topic work is priced on request rather than added as extra minutes to one session. Coverage, examiner details and the full service list for Toronto, Vancouver, Montreal, Calgary, Edmonton, Ottawa, Winnipeg, Hamilton, Halifax and other cities are set out on the union’s lie detector test Canada page.
What the result is worth, and where its limits are
A polygraph report is not decisive evidence. Courts are not obliged to accept one, and where it is considered at all it is weighed alongside documents, messages and testimony. Its real value sits earlier in the process: in pre-action negotiation, in mediation, and in family decisions about whether to pursue a claim at all.
Employment is a separate matter with its own boundaries. In some provinces employment standards legislation gives employees an explicit right to refuse a lie detector test and prevents an employer from requiring one, so workplace screening is only ever a voluntary arrangement agreed in advance. For private disputes between individuals the governing rule is simpler: both parties participate because they choose to.
When a test will not help
- The amounts and dates are already visible in bank records, where an accountant or lawyer is a better first step
- The disagreement concerns the interpretation of a written contract rather than hidden actions
- The other party refuses all contact, since an examination cannot proceed without consent
- The sum in dispute is comparable to the combined cost of the examination and the advice
- One side has already decided what to do and wants validation
Can a written agreement be built from the result
Frequently, yes, and this is the most common practical outcome. Once the contested facts are narrowed, the parties sign a repayment schedule or a settlement that reflects them. The report is attached as background rather than treated as a finding of liability.
What if the other person agrees only to an informal result
That is a workable option. A verbal outcome delivered on the day suits private decisions, while a written report with charts is ordered when the matter may reach lawyers or a tribunal.
How soon can an examination be arranged
Preparation usually takes one to three short conversations, after which the session itself is a single appointment. Collecting dates, amounts and the sequence of events in advance shortens that preparation considerably and keeps the quote predictable.
