Private Investigation Services in Toronto
Whether you're dealing with suspected infidelity, a child custody concern, workplace misconduct, a questionable insurance claim or the possibility of hidden surveillance, the right approach starts with understanding what needs to be established. Our licensed investigators use surveillance, background research, online investigations and technical surveillance countermeasures (TSCM) where appropriate to uncover and document facts. Explore our four areas of practice below to find the investigation services that fit your situation.
Personal & Family Investigations
Personal and family investigations help individuals establish facts when concerns involve a spouse or partner, parenting arrangements, a person's background or a missing loved one. Our licensed private investigators work on suspected infidelity, divorce and separation, child custody matters, premarital background checks and missing-person enquiries. Depending on the circumstances, fact-finding may involve discreet surveillance, documented observations, lawfully available public records, background verification or interviews. The objective is to establish what can be verified, rather than rely on assumptions—particularly in sensitive matters involving children, domestic abuse or personal safety.
Surveillance & Specialist Investigations
Surveillance and specialist investigations establish facts about activities, online identities or suspected unauthorized monitoring. Physical surveillance can document a person's movements and observable behaviour through time-stamped notes, photographs and video. Social media and internet investigations examine lawfully accessible profiles, public posts and digital connections; Technical Surveillance Countermeasures (TSCM) assess concerns involving hidden cameras, listening devices and trackers. These capabilities may support infidelity enquiries, insurance claims, employee investigations and corporate security. The method depends on the question being investigated and the lawful information available—not every matter requires surveillance or a technical sweep.
Corporate & Workplace Investigations
Corporate and workplace investigations help employers, executives and business advisers assess suspected fraud, employee misconduct, undisclosed conflicts and commercial risk. Internal enquiries may examine theft, misuse of company information or irregular relationships between employees and outside parties. Investigative due diligence and pre-employment screening verify relevant business affiliations, identity, work history and professional credentials before important hiring or commercial decisions. Depending on the assignment, investigators may review available records, interview relevant people, establish timelines and document lawful observations. Findings help organizations distinguish supported facts from allegations and decide what warrants further action or legal advice.
Legal & Insurance Investigations
Legal and insurance investigations provide independent fact-finding for law firms, insurers, claims professionals and businesses when events or accounts are disputed. Insurance claims investigations may examine suspected staged accidents, injury or disability claims and claimant activity through records review and lawful surveillance. Litigation support can help verify background information, establish timelines and locate people relevant to family, civil or commercial matters. Skip tracing develops and cross-checks leads to locate witnesses, debtors, beneficiaries or claimants. The resulting documentation helps advisers evaluate evidence and next steps; investigators do not determine liability, coverage or whether evidence will be admitted in court.
