Private investigators and police officers can share information in limited situations, but they are not the same job and they do not share police powers. In Ontario, a licensed private investigator works for a private client under provincial licensing rules, while police investigate offences under public authority. Investigation Hotline is a licensed firm serving Toronto, the GTA, and province-wide. For hiring process basics, see our Ontario hiring guide. This page explains when PIs and police interact, when they do not, and how to choose the right path for your situation.
Do private investigators work with the police?
Sometimes, yes, in practical ways. A PI may provide a report, timeline, or lead that a client later shares with counsel or law enforcement. In other files, police and investigators never speak. Most civil and personal investigations never become criminal files.
What does not happen is the TV version: a PI flashing a badge, running joint raids, or replacing detectives. Licensed investigators cannot impersonate police. They cannot claim arrest powers as officers. They must follow municipal, provincial, and federal law, including Ontario’s private security and investigative licensing framework.
Confirm licensing using Government of Ontario guidance on security guard or private investigator licences.
How are private investigators different from police?
- Authority: Police act for the public. Investigators act for a paying client within legal limits.
- Trigger: Police prioritize public safety and criminal offences. Investigators often handle civil, family, corporate, and locate needs police will not open or cannot prioritize.
- Methods: Both must obey the law. Investigators do not get special exemptions for trespass, illegal recording, or hacking.
- Outcome: Police files can lead to charges. PI files usually produce documentation for personal decisions, HR, insurers, or counsel.
If you need emergency help, call police. A private investigator is not a 911 substitute.
When do PIs and police interact?
Client-driven information sharing
The most common path is indirect. A client receives a professional report and, with counsel, decides whether to involve police. The investigator’s role is documentation, not deciding charges.
Leads that support a police file
In some cases, lawful observation or research produces information a client wants police to review. Quality matters: dates, locations, notes, and media that can be explained. Weak or illegally obtained “proof” can hurt more than help.
Parallel tracks on different questions
A family may speak with police about safety while hiring an investigator for a civil timeline. A business may report theft while also documenting internal patterns for HR or insurers. Parallel does not mean joint command.
What “working with police” is not
It is not a standing partnership that lets a PI open locked doors, demand records with police authority, or detain people. Any firm that markets itself as having police powers is a red flag.
When should you call police instead of a PI?
- Immediate danger, assault, stalking with urgent risk, or active threats
- A crime in progress
- Situations where only police can compel evidence with lawful authority
- Child endangerment or emergencies that need public responders now
After safety is handled, a licensed investigator may still help with civil documentation, locate work, or workplace fact-finding that sits outside a criminal process. Timing and roles should stay clear.
When a private investigator may help when police will not
Police resources are limited. Many civil questions never become active criminal investigations. Common private-investigation lanes include relationship documentation, custody-related observations directed by counsel, workplace misconduct fact-finding, due diligence before a hire or deal, insurance-related observation, and locate work for civil needs.

What can a licensed PI do lawfully?
Typical lawful work includes open-source and records research within legal limits, surveillance in places where observation is lawful, interviews with consent where appropriate, documentation of patterns, and written reporting for clients or counsel.
Hard limits include trespass, breaking into property, impersonating a police officer, unlawful interception of private communications, and illegal access to accounts or devices. Tracking and recording methods also have strict legal boundaries. A professional firm will refuse illegal requests rather than “work around” them.
Investigation Hotline has served Ontario clients since 1988 under founder Mitchell Dubros. In intakes, clear boundaries protect both the client and the file.
Does a PI report everything to police?
No. Private investigations are confidential business for the client, subject to law. Investigators are not a public reporting desk. If a situation involves imminent harm, professionals still prioritize safety and lawful obligations. For most civil files, the client and counsel decide what, if anything, goes to police.
Ask about confidentiality, file storage, and who can access notes and media. Those details matter as much as fieldwork skill.
Also ask whether the firm will speak directly with police if your counsel requests it, or whether communication stays client-mediated. Preferences differ by file. Clarity up front prevents awkward mid-case surprises.
Can private investigators arrest people?
Do not hire a PI expecting police-style arrests. Investigators do not have police arrest authority. Limited civilian arrest concepts exist in Canadian law in narrow circumstances, but they are high-risk, fact-specific, and not a service product. Ethical firms focus on documentation, not detention theatrics.
Impersonating police, flashing fake credentials, or claiming special arrest powers is illegal and a reason to walk away.
How should clients talk about police and PI work in intake?
Be honest about what you already told police, whether a file number exists, and whether counsel is involved. If you want a report that could later support a complaint, say so early so documentation standards match that goal.
Do not ask an investigator to interfere with an active police investigation, coach witnesses improperly, or obtain evidence illegally “because police are slow.” That creates liability and can damage credibility.
A useful first call covers objective, urgency, geography, prior DIY attempts, and whether the outcome is for personal decision-making, HR, insurers, counsel, or possible later reporting.
If you already collected photos, messages, or notes, bring a summary of what you have and how you got it. Lawful materials can help scope. Illegal materials can create problems. An ethical investigator will say which is which.
Practical examples of role separation
- Suspected theft at work: Report urgent safety issues to police. Use a PI or workplace investigation process for internal fact-finding and policy decisions when independence matters.
- Missing adult with civil locate needs: Police may or may not open a priority file. A PI can run structured locate work for family or counsel while you keep safety reporting channels clear.
- Relationship documentation: Usually civil. Police are not a substitute for discreet pattern documentation, and a PI is not a substitute for emergency protection.
- Harassment with fear for safety: Start with police and safety planning. Investigation support, if any, should follow legal advice and not escalate risk.
How to choose a firm that respects the police boundary
- They explain licensing and refuse illegal methods without hedging.
- They do not claim police partnerships as a sales gimmick.
- They ask what decision the file supports.
- They can describe reporting format for counsel or HR.
- They treat emergency risk as a police-first issue.

Do private investigators work with the police FAQs
Are private investigators allowed to help police?
They may provide information a client later shares, or cooperate when lawfully appropriate. They do not become police officers by helping.
Will hiring a PI get someone charged?
No guarantee. Charges are a police and Crown decision. A PI produces facts and documentation. Outcomes depend on the evidence and the legal process.
Should I hire a PI if police already have a file?
Maybe, for civil needs that sit beside the criminal process. Do not hire anyone to interfere with police work. Tell both your counsel and the investigator what is already active.
Can a PI get phone records or bank records like police?
Not with police compulsion powers. Lawful research has limits. Anyone promising secret warrant-level access without process is a red flag.
If police closed a case, can a PI still help?
Sometimes, for civil documentation or locate leads. Results are not guaranteed, and methods must stay legal.
Does working with a PI hurt a future police complaint?
Illegal DIY evidence can hurt. Professional, lawful documentation is more likely to remain usable. Ask counsel how reporting should be structured if a complaint is possible.
