Counter Surveillance
Detect whether someone is watching, following, or monitoring you — then help you change that picture.
Counter-surveillance answers a different question than bug sweeping. TSCM looks for devices. Counter-surveillance looks for people, vehicles, and patterns that mean you are being followed, watched, or boxed in. Executives, counsel, people in bitter family disputes, and anyone who has already found a tracker often need both. Investigations Plus runs route checks, static detection, and protective observation so you can move with a clearer picture.
When this service is the right file
- The same vehicle or face keeps appearing near your home, office, or child’s school.
- A tracker was found on a car and you need to know whether a live follow is still running.
- You are in a high-conflict dispute and want to know if you are being filmed for leverage.
- A public figure or executive wants a clean arrival to a meeting or residence.
- You feel watched and need a professional to confirm or disconfirm before you change your life around a fear.
How the investigation is done
We start with your routes, schedules, parking habits, and the incidents that triggered the concern. Investigators then run detection runs: varying your departure, using choke points, and watching who reacts. We log plates, make/model, and behaviour — pacing, leapfrogging, repeated passes. If a follow is confirmed, we document it and discuss whether to break it, ignore it, or involve police. If nothing is there, that finding still has value. Device sweeps are a sister service; we will recommend TSCM when the threat looks electronic rather than human.
What you receive
- Detection-run logs and maps
- Photographs of suspect vehicles or individuals from lawful positions
- A judgement on confirmed, possible, or unfounded coverage
- Practical changes to routes and habits
- Referral notes if the conduct appears criminal
Legal and ethical limits
We document watchers. We do not assault them, trap them, or impersonate police. If the other party is a licensed investigator on a lawful file, the answer may be that you are being observed legally. We will still tell you what we saw. Harassment and stalking are police matters when thresholds are met; we preserve evidence for that hand-off.
Who typically retains this work
Individuals in conflict, corporate principals, lawyers protecting a witness, and people who already found a device. We decline requests to counter-surveil someone as a way to interfere with a lawful investigation of your own conduct.
Where we handle these files
Detection runs are common in the GTA and throughout Ontario. Protective work for travel inside Canada is planned as an operation with start and end points.

If you keep seeing the same car, do not confront the driver. Call for a confidential counter-surveillance assessment and let licensed investigators test the pattern.

Questions about Counter Surveillance
No. Close protection is a different licence and skill set. We detect and document surveillance. We can coordinate with security if you already have it.
Then the report should say unfounded. That is still a useful outcome.
If devices are in play, combine this with TSCM. Habits, locks, and accounts are a package when the threat is serious.
