How a Windsor P300 EEG Test Actually Runs

The practical detail clients ask about most: how do we get to Windsor, where does the test happen, what does the day look like, what does the written report include. Everything below is the same whether you book a single test, a two-person visit, or a dedicated visit.

Travel to Windsor

UK-qualified examiner inbound to Windsor International (YQG) or Detroit (DTW) — 9 hours via Toronto or Detroit. Medical-grade 8-channel BrainBit EEG kit travels as cabin baggage in cushioned cases. Examiner arrives the day before to clear time-zone fatigue and any travel delay.

Venue in Windsor

reserved suite at a downtown Windsor, riverside or Devonshire-area hotel. Corporate premises also accepted for workplace investigations. Venue is booked in advance and confirmed in writing once payment clears — strict confidentiality from the front desk.

The Windsor Day

30-minute pre-test interview, 30 mins P300 EEG examination, 30-minute post-test debrief, then waveform analysis on-site. Total venue time: around 3.5 hours. Written report handed to the paying client within 2 hours of the test ending.

The Report

8-page forensic report — raw waveform data, P300 spike analysis per probe question, deception score breakdown, methodology summary, signed certificate of examination. Issued only to the paying client; never copied or shared.

Confidentiality

The Windsor venue is booked under our company name, not yours. The examiner arrives in plain clothes with unmarked equipment cases. Nobody at the venue is told what the booking is for. Records are held under UK GDPR standards, fully compatible with PIPEDA (and Quebec Law 25, BC PIPA or Alberta PIPA where the test takes place in those provinces).

Payment from Windsor

CAD or GBP via international bank transfer, Wise, or major credit card. Invoiced by DadLink Technologies Limited (UK). Full payment confirms the booking — this is how we hold your trans-Atlantic travel slot. No deposits on international bookings.

Why P300 EEG in Windsor

Brain-Wave Testing. Not Sweat & Heart Rate.

In Windsor, plenty of polygraph operators are available — but they all rely on technology that has not fundamentally changed since the Cold War. The P300 EEG is a brain-wave test — it measures the involuntary recognition spike that fires 300 milliseconds after your brain spots a familiar detail. It is faster, harder to fool and considerably more accurate. And our examiner has no Canadian agency ties — fully independent of the local market.

Traditional Polygraph

  • Measures anxiety symptoms — not truth directly
  • Heavily affected by nerves, anger, stress
  • Countermeasures documented widely online
  • Accuracy ~85-89% on single-issue tests
  • Subjective chart interpretation
  • Local providers may have agency ties

P300 EEG (What We Do)

  • Measures brain recognition — not emotional state
  • Involuntary neural response — hard to suppress
  • Countermeasures don't block P300 spikes
  • 95% accuracy on guilty-knowledge protocols
  • Objective waveform analysis
  • Fully independent UK examiner flown to Windsor
Who Books This in Windsor

Built for Windsor's Most Common Cases

Most Windsor clients are in a similar position when they first call: they have asked the question directly, not got the answer they trusted, and tried everything short of formal investigation. Below are the six contexts where a P300 EEG test consistently breaks the deadlock for Windsor clients.Most Windsor clients are in a similar position when they first call: they have asked the question directly, not got the answer they trusted, and tried everything short of formal investigation. Below are the six contexts where a P300 EEG test consistently breaks the deadlock for clients.

Relationship & Infidelity

Private, discreet testing for cheating allegations, emotional affairs, messaging history disputes, or to verify a partner's statements before trust is rebuilt. Confidential venue, written report within 2 hours. Test both partners on the same visit for just £2,299 — saves £1,299.

Family & Household

Theft in the home, inheritance disputes, adult children under suspicion, sibling disagreements, or accusations within blended families. Clear, objective answers without police involvement.

Business & Workplace

Specific-incident investigations with employee consent — missing stock, data leaks, suspected fraud, internal misconduct allegations. Test multiple suspects on one visit for significantly lower per-test cost.

False Accusations

If you've been accused of theft, dishonesty or misconduct at work or in your personal life, a passed P300 EEG test provides objective brain-wave evidence that you're telling the truth — far more robust than your word alone.

Pre-Relationship / New Partner

Past behaviour verification, dating-profile honesty, discrete checks before a serious commitment. Used quietly by many Windsor clients before getting engaged, buying property together, or introducing someone to children.

Second Opinion

Previously failed a polygraph elsewhere and want an independent P300 EEG test on the same facts? P300 measures brain recognition, not anxiety — so a nervous polygraph result doesn't predict a P300 result. Clean slate, different technology.

What Windsor Clients Say

★ 4.9 / 5 · based on 499 verified reviews across Deception Detection UK

★★★★★

Resolved a contested accusation cleanly and quickly

"We had a household theft accusation between two adult family members that had been simmering for months. One session resolved it. The relationship was repaired. Best money I have spent in a long time."

Lucas D. · Windsor · Apr 2026
★★★★★

Second-opinion test after a polygraph fail

"My polygraph result came back deceptive and I knew it was wrong. I had been nervous on the day but had nothing to hide. The P300 test cleared me cleanly. Different science, different result, and finally the truth on paper."

Léa M. · Windsor · Mar 2026
★★★★★

Examiner travelled to a corporate venue in central business district

"We did not want staff at our office knowing the test was happening so the examiner came to a serviced office we hired for the day. The whole thing was invisible to the wider team. Exactly what we needed."

Henry K. · Windsor · Feb 2026
★★★★☆

Multi-person test for a family-business accusation

"Five family members all working in the same family business, all under suspicion for a missing sum. The grouped visit tested all five in one day. Four passed, one did not. Hard conversation afterwards but at least we had certainty."

Eleanor S. · Windsor · Jan 2026
★★★★★

First definitive answer I have had in two years

"I had been carrying a question about my partner for nearly two years. The test gave me a definitive answer in a single session and I am finally able to move forward. There is no price I would not have paid for that."

Connor R. · Windsor · Dec 2025

Windsor FAQ

Common Questions From Windsor Clients

For a Windsor booking, dedicated turnaround is 14 days from full payment via Windsor International (YQG) or Detroit (DTW) (9 hours via Toronto or Detroit). Scheduled-visit turnaround depends on the next Canada trip we have planned — usually 4-6 weeks out. Faster Windsor visits are sometimes possible if there is already a booking nearby on a date you can match — call us and we will check the diary.

Yes — and it's our most popular option in Windsor. 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 Windsor 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.

Important: Our service is for private, voluntary, consenting-parties use — personal resolution, relationship and family matters, specific-incident internal investigations with written consent, and matters of private dispute resolution. All examinations require written consent from the person being tested. Reports are issued only to the paying client. Accuracy figures refer to published P300 EEG research performance on guilty-knowledge test protocols. We do not present P300 results as formal trial evidence; consult qualified Canadian counsel if your matter involves litigation. All testing in Canada is conducted in compliance with PIPEDA and any applicable provincial privacy regime (Quebec Law 25, BC PIPA, Alberta PIPA).
