A civil investigator is a licensed private investigator who gathers facts for non-criminal matters: family disputes, civil lawsuits, insurance claims, and other private disputes where police will not run a full investigation. In Ontario, that work is done under provincial licensing rules. Investigation Hotline supports civil files across the GTA with discreet documentation counsel can review. This page explains what civil investigators do. Deep guides for each specialty live on their own service pages.

How is a civil investigator different from a criminal investigator?

Criminal investigators (police or specialized units) work toward charges and public prosecution. Civil investigators work for private clients, lawyers, insurers, or employers on matters that usually end in family court, civil court, settlement, or internal decisions. Methods still must stay lawful. Illegal recording, hacking, or trespass can ruin evidence and create liability whether the file is civil or criminal.

Who hires: spouses, parents, counsel, insurers, and businesses that need verified facts outside a police file.

What you receive: scoped intake, lawful surveillance or research, written findings, and exhibits where appropriate.

What this is not: a substitute for emergency services when someone is in immediate danger.

What personal and family matters do civil investigators handle?

Many clients use “civil” or “domestic” for family-related work. Common files include suspected affairs, parenting disputes, domestic abuse documentation, stalking concerns, and caregiver or babysitter checks. Each of those has its own methods and legal limits. For affair documentation, see infidelity and cheating partner investigations. Parenting and domestic-violence related evidence is covered under child custody and domestic violence investigations. Abuse documentation is outlined in our domestic abuse investigation service. This article will not restate those full playbooks.

What does civil investigation look like day to day?

Work often mixes discreet surveillance in public places, open-source research, interviews where appropriate, and records work the client is entitled to request. Investigators document dates, times, locations, and photographs or video when lawful. Reports are written so a lawyer can assess usefulness. They do not invent guilt; they record what can be observed and verified.

Do civil investigators work on lawsuits and insurance files too?

Yes. Civil investigation is broader than family files. Claimants, defendants, and insurers hire investigators for activity checks, statements, scene documentation, and fraud concerns. Employers may need workplace fact-finding that is civil or administrative rather than criminal. Those tracks use different scopes and reporting standards than a custody file. Ask at intake which lane your case sits in so the plan matches court or claims requirements.

When should you hire a civil investigator instead of DIY research?

Hire when outcomes depend on evidence that must hold up under scrutiny: separation talks, custody motions, restraining-order support, caregiver hiring decisions, or civil discovery. DIY following, secret devices, or friends “helping” often tip subjects off and create biased or illegal material. Background screening of a caregiver or household worker is safer through structured background checks than informal online snooping alone.

Stalking concerns are another civil trigger. If you believe someone is following you or a relative, an investigator can document patterns in public places to support safety planning or counsel. Do not confront a suspected stalker alone. Preserve threatening messages and call police when there is an immediate threat.

Will civil investigation evidence hold up in court?

Lawful collection, clear notes, and proper chain of custody improve the chance counsel can use findings. Courts still decide weight and admissibility. For Ontario-focused guidance on that question, see will PI evidence hold up in court. Tell your investigator early if a hearing date or affidavit is planned so reporting matches that timeline.

Civil investigators also have limits. They are not lawyers, judges, or social workers. They document facts; they do not decide custody outcomes or guarantee a settlement. Expect a report and exhibits, not a verdict.

What should you prepare before the first call?

  • Write the decision you need to make (custody, separation, hiring, claim) in one sentence.
  • List names, photos, addresses, vehicles, and known schedules.
  • Preserve messages or documents you already have without altering them.
  • Note safety concerns so intake can flag urgency.
  • Ask whether your lawyer should join the kickoff call.

Frequently asked questions

Is a civil investigator the same as a private investigator?

In practice, yes: civil investigators are private investigators focused on non-criminal client matters. Licensing still applies in Ontario.

Can a civil investigator testify in family court?

Often they can be called as a witness to explain how facts were gathered. Your lawyer decides whether testimony helps.

How long does a civil investigation take?

It depends on scope. Narrow surveillance or a background check can finish in days; contested family or multi-party civil files can run longer.
