Cheating Spouse and Infidelity Investigations
When trust is in question, we help you find calm, factual answers — discreetly and lawfully.
Private Investigators for Cheating Cases
Suspecting that a partner is unfaithful is painful, and living with the uncertainty can be worse. We help you replace suspicion with facts. As private investigators for cheating cases, we approach every matter quietly and without judgement: we listen to what you have noticed, explain what we can lawfully establish, and agree a careful scope with you before we begin.
We are often the right next call when you have questions about a relationship — whether that leads to an investigation or simply to a clearer conversation about your options. If your matter later involves separation or custody questions, our family law investigations and investigations for lawyers can support your legal team as well.
Surveillance for Infidelity Investigations
Where surveillance is appropriate, we carry it out discreetly and lawfully, documenting what we observe with dates, times, and clear notes. We work in public places and within the same professional standards we apply to every file. You receive a plain-language report of our findings, and we talk it through with you — what it shows, what it does not show, and what you might do next.
Video Surveillance Laws in Canada
In Canada, investigators must respect privacy law and the rules that govern how evidence is gathered. We do not trespass, we do not record private conversations we are not part of, and we do not use tracking or access methods the law does not allow. Working within those limits protects you: findings gathered lawfully are findings you can rely on, including with a lawyer. We explain the limits that apply to your matter in our consultation, before any work begins.
What an investigation costs depends on scope, time, travel, and complexity — see how much a private investigator costs for the factors involved.

Yes. We handle your inquiry and case details privately from our first conversation onward. Share only what you are comfortable sharing at each stage, and we will not ask for more than we need.
We work within BC law and professional standards: careful observation in public places, documented fieldwork, and research we can stand behind. We explain what is and is not possible before we begin, so your expectations are realistic.
A clear report of our findings — what we observed, when, and what it means — so you can decide your next step with your family, your counsellor, or your lawyer, based on facts rather than suspicion.
Cost depends on the scope, time, travel, and complexity of your matter. We discuss the likely cost with you in a confidential consultation and agree an estimate before we begin. See our page on how much a private investigator costs for what affects the price.
No. Many people who reach out to us are not certain of anything — they simply know something does not add up. We listen first, and we will tell you honestly whether an investigation is likely to help in your situation.
