Lie Detector Test Montreal — P300 EEG Examiner in Montreal

Yes. Most Montreal bookings are exactly that — a single test that justifies a single international visit. The economics work because we charge the dedicated-visit rate (£2,999) for that scenario. If you can wait for our next scheduled Canada visit (we run rolling trans-Atlantic trips via Montreal Trudeau (YUL) — 7 hours direct from London Heathrow) the price drops to £1,799 single and we share the flight cost across multiple cases on the same trip.

Yes — and it's our most popular option in Montreal. Two tests on the same day cost £2,299 instead of £3,598 if booked separately — that's a £1,299 saving. For corporate investigations we offer 3-test packages at £2,999, 5-test at £4,499, and 10-test at £7,999 (£799 per test — see the Canada hub for the full corporate tiers). Ideal for couples, business partners, family members in a dispute, or staff in a specific-incident investigation.

Traditional polygraph measures anxiety — breathing, heart rate, sweat. P300 EEG measures a specific brain-wave that fires involuntarily when your brain recognises a detail you've seen or done before. It's measurably more accurate (95% vs ~85%), not defeated by common countermeasures, and not distorted by nervousness. Crucially, a guilty person's brain still recognises the crime even if they're calm — and an innocent person's brain won't recognise details they've never seen, no matter how anxious they are. And because our examiner is UK-based, there are no ties to any Canadian polygraph firm, police service or adversarial party.

Strictly confidential. Tests in Montreal take place in private booked venues. Reports are issued only to the paying client. We operate under UK GDPR standards, which are fully compatible with PIPEDA — and with the province-level regimes that may also apply (Quebec Law 25, BC PIPA, Alberta PIPA). We do not share, store or disclose any case information to third parties without written instruction. Nothing is filed with any authority, employer or family member unless you explicitly ask us to.

Very common reason for booking us. Traditional polygraph results can be distorted by nerves, medication, medical conditions, or poor question design — a genuinely truthful person can fail simply by being anxious. P300 EEG measures something different: brain recognition, not anxiety. A P300 test on the same underlying facts can provide a clear, independent second result.

Yes — and Canada is actually easier than the US for this. There's no Canadian equivalent of the US Employee Polygraph Protection Act (EPPA), so consent-based internal investigations have more flexibility. That said, testing must be genuinely voluntary, with written employee consent, and compliant with PIPEDA plus any relevant provincial privacy law (notably Quebec's Law 25, and separate BC/Alberta regimes). Our Corporate Packages (3, 5 and 10-test) are designed exactly for this — per-test rates drop to £799 on the 10-pack.

We accept CAD or GBP via international bank transfer, Wise, or major credit cards. All invoices are issued by DadLink Technologies Limited (UK). Full payment is required to confirm the booking — we don't take deposits on international bookings because the trans-Atlantic flight slot has to be paid up front. This protects both parties and secures examiner travel arrangements.

Tests are conducted in English. For visits in Quebec and New Brunswick where French is preferred, we can arrange a qualified French interpreter locally — just raise this at the enquiry stage so we can factor it into scheduling. Other languages (Mandarin, Cantonese, Punjabi etc.) can also be accommodated with sufficient notice.
