Surveillance is one of the most powerful tools in private investigations, offering concrete, irrefutable evidence in a range of cases. Whether you’re dealing with a cheating spouse, fraudulent employees, or insurance scams, private surveillance services can uncover the truth and provide the documentation you need to take action.


But how does surveillance work? What are the legal boundaries in Ontario? And when should you hire a Niagara private investigator for surveillance?

At Cat Claw Investigations, we specialize in discreet, professional surveillance services tailored to your specific needs. In this guide, we’ll break down the ins and outs of private surveillance investigations, including techniques, legal considerations, and real-life case studies.


What Is Private Surveillance?


Private surveillance involves the covert monitoring of individuals, locations, or activities to gather evidence for legal, personal, or business matters. Unlike casual observation, professional surveillance is conducted systematically and ethically, ensuring the collected evidence is both accurate and legally admissible.


Surveillance can be used to:
  • Document infidelity in divorce cases

  • Expose fraudulent insurance claims

  • Monitor workplace misconduct and employee theft

  • Locate missing persons and runaways

  • Uncover theft or fraud in businesses


A professional private investigator in Niagara uses a combination of physical surveillance, digital intelligence, and detailed documentation to gather the crucial evidence you need.

Types of Private Surveillance Services


  1. Infidelity & Cheating Spouse Surveillance

Suspect your partner is being unfaithful? Private surveillance can provide definitive proof with photos, videos, and timestamps, giving you clarity and legal leverage.


Case Example:

A woman in Fonthill suspected her husband of infidelity. A PI conducted evening surveillance and captured evidence of her husband meeting another woman at a secluded restaurant in Port Dalhousie. This evidence was later used in her divorce case to support her claims.


  1. Insurance Fraud Investigations

Fraudulent insurance claims cost businesses millions every year. Private investigators can conduct surveillance to determine whether a claimant is exaggerating injuries or engaging in activities inconsistent with their claims.


Case Example:

A man in St. Catharines claimed he had a severe back injury that prevented him from working. However, surveillance footage captured him lifting heavy boxes. The evidence saved the insurance company thousands in

fraudulent payouts.


  1. Workplace & Employee Surveillance

Employers often hire private investigators to monitor employees suspected of theft, fraud, or misconduct. Surveillance helps protect businesses from financial losses and legal liabilities.


Case Example:

A business in Niagara Falls hired a PI to investigate an employee suspected of stealing. Surveillance caught the employee pocketing goods and returning them for a refund at another location. The evidence led to their termination and subsequent legal action.


  1. Child Custody & Family Law Investigations

In contentious child custody cases, surveillance can verify whether a parent is following court-ordered visitation rules and providing a safe, stable environment for the child.


Case Example:

A father in Grimsby suspected his ex-partner of leaving their child unsupervised while she went out at night. Surveillance revealed she was frequently leaving the child home alone, which led to a modification in the custody arrangement.


  1. Missing Persons & Skip Tracing

Private investigators use surveillance, public records, and witness interviews to locate missing persons, including runaways, estranged family members, and debtors.


Case Example:

A family in Niagara-on-the-Lake hired a PI to find a long-lost relative who had disappeared 10 years earlier. Through surveillance and investigative work, the relative was found living under a new identity in the GTA.


Surveillance Techniques Used by Private Investigators


  1. Physical Surveillance (Stakeouts & Fieldwork)

  2. Observation from a distance using high-powered cameras.

  3. Tracking the subject’s movements without detection.

  4. Documenting behaviour with time-stamped photos and video.

  5. Vehicle Surveillance

  6. Following a target in traffic discreetly.

  7. Using multiple investigators to prevent detection.

  8. GPS Tracking (When Legal)

    • Note: GPS tracking can only be used if the tracker is placed on a company-owned vehicle or with legal consent.

  9. Public Record & OSINT (Open-Source Intelligence)

  10. Social media monitoring to detect hidden relationships or financial activities.

  11. Checking court records, business filings, and past addresses for additional context.


Legal Considerations for Private Surveillance in Ontario

Ontario has strict regulations governing what private investigators can and cannot do during surveillance. Understanding these laws is essential to ensure that evidence remains admissible in court.


  1. Trespassing Laws

Private investigators cannot enter private property without explicit permission. All surveillance must be conducted from public spaces or legally accessible areas.


  1. Privacy & Audio Recording

It is illegal in Ontario to record private conversations unless at least one party involved gives consent. Private investigators must follow strict guidelines to ensure evidence collection is legal and ethical.


  1. GPS Tracking Laws

Private investigators cannot place GPS trackers on a subject’s vehicle unless the vehicle is owned by the client or proper legal consent has been obtained.


  1. Admissibility of Evidence in Court

For surveillance evidence to be admissible in court, it must be:

  • Collected legally and ethically.

  • Properly documented with clear timestamps and supporting data.

  • Authenticated by a licensed professional investigator.


Hiring a licensed private investigator in Niagara ensures that all evidence is gathered legally and can be used to support your case in court.
