When It Works, When It Doesn’t, and How It’s Used
What Is Surveillance?
At Kusic & Kusic, surveillance is one of the most valuable investigative tools we use. In simple terms, surveillance is the careful observation of a person, activity, or location for the purpose of gathering information. Our role is usually to remain discreet, observe what happens in public, and document relevant activity without becoming part of the situation. That is very different from overt security, where cameras, guards, or visible patrols are meant to be noticed and deter unwanted behaviour.
Surveillance vs. Stalking
We are often asked about the difference between professional surveillance and stalking. The distinction is important. Stalking involves harassment, threats, repeated unwanted contact, or monitoring for an illegitimate purpose. Professional surveillance is conducted for a legitimate investigative objective and within the limits of Canadian and British Columbia law. At Kusic & Kusic, we work under clear client instructions and lawful authority, and our investigators are properly licensed in British Columbia. We do not trespass, impersonate others, or unlawfully record private conversations.
Why a Clear Objective Matters
Surveillance works best when there is a specific question to answer. Most clients come to us because they have a reasonable concern but lack objective proof. A focused surveillance plan can help confirm patterns, identify inconsistencies, establish timelines, or document activity. In many cases, short and well-timed periods of observation are more effective than prolonged surveillance without a clear purpose.
When Is Surveillance Most Effective?
We use surveillance in a wide range of investigations throughout British Columbia, from Metro Vancouver and the Fraser Valley to the Kelowna-Penticton corridor, Southern Vancouver Island, the Interior, and Northern BC. The location changes, but the basic objective remains the same: observe and document relevant activity as accurately and discreetly as possible.

Insurance Fraud and Workplace Injury Claims
Insurers and employers often contact us when reported physical limitations appear inconsistent with an individual’s activities. A person may claim they cannot work because of an injury while also participating in cycling, golf, soccer, hockey, rugby, martial arts, or other physically demanding activities. Our job is not to decide whether a claim is fraudulent. We document what is observable so the client can compare the evidence with the limitations that have been reported.
Child Custody and Family Law Investigations
Surveillance can also assist in family law and parenting matters. A parent, family member, or legal professional may have concerns about activities taking place during parenting time, substance use, work activity, or other behaviour relevant to a dispute. Whether the matter is in Vancouver, Surrey, Victoria, Nanaimo, Kelowna, or another BC community, properly gathered and documented evidence can be important when information may later be used in legal proceedings.
Infidelity and Relationship Investigations
Relationship investigations are another common use of surveillance. Clients may be dealing with rumours, unexplained late nights, unusual phone activity, changes in routine, or a general sense that something is not adding up. In these cases, our role is to document observable behaviour and provide objective information. That may include meetings, restaurant visits, hotels, bars, or public displays of affection. The client can then make decisions based on facts rather than assumptions.
Executive Protection and Personal Security
Surveillance can also be used proactively to identify security concerns involving executives, professionals, public figures, or high-net-worth individuals. Online exposure can make personal routines, residences, workplaces, and travel patterns easier to identify. We may assess suspicious activity around a residence, office, vehicle, or predictable route, whether the concern arises in downtown Vancouver, the Okanagan, Vancouver Island, or elsewhere in BC.
When Surveillance May Not Be the Right Tool
Surveillance is not appropriate for every investigation. If the issue depends mainly on historical records, documents, online information, or past events, another investigative method may be more useful. Surveillance can only document what can lawfully be observed; it cannot determine intent or recreate events that have already happened.
Is Surveillance Right for Your Situation?
Surveillance does not guarantee a particular result. There may be periods when nothing relevant occurs, and some findings may remain inconclusive. When used with a clear objective, however, surveillance can provide valuable real-world evidence and help clients make better-informed decisions.

Frequently Asked Questions About Infidelity Investigations
Private investigator surveillance can be lawful in British Columbia when it is conducted for a legitimate investigative purpose and in accordance with applicable laws and privacy requirements. Licensed investigators must operate within the requirements that apply to private investigation and security work in BC. Surveillance should be conducted without unlawful trespassing, harassment, or unreasonable interference with a person’s privacy.
Surveillance is most effective when there is a clear investigative objective and a specific question that needs to be answered. Well-timed surveillance can help establish patterns, verify reported activities, identify inconsistencies, or document events that occur in observable circumstances. The length of an investigation depends on the circumstances and what needs to be established.
Depending on the circumstances, an investigator may document observable activities, movements, locations, interactions, timelines, and other relevant events. Investigators may also use photographs, video, written observations, and detailed activity logs where appropriate and lawful. Surveillance does not establish someone’s intent by itself; it documents observable facts that can then be assessed by the client or their legal representative.
Surveillance may not be the best approach when the investigation primarily depends on historical records, documents, online information, financial records, or events that have already occurred. In those situations, other investigative methods may be more appropriate. A private investigator can help determine which approach is most suitable before surveillance begins.
There is no standard duration for every surveillance investigation. The timeframe depends on the investigative objective, the subject’s routine, location, available information, and how frequently relevant activity occurs. Some investigations may require only a short period of observation, while others may require multiple surveillance sessions.
