Domestic Abuse Private Investigator in Ontario

A domestic abuse private investigator in Ontario is a PSISA-licensed professional retained to lawfully document evidence of family violence for a lawyer, a court, or a safety plan. Only a licensed investigator may lawfully perform this work under Ontario’s Private Security and Investigative Services Act, 2005.

Statistics Canada recorded 128,175 victims of police-reported intimate partner violence across Canada in 2024, a rate of 356 per 100,000 population aged 12 and older, while roughly 80% of spousal violence goes unreported to police according to the 2019 General Social Survey. See domestic abuse statistics in Canada for the full national and Ontario-specific breakdown. This guide explains what the role covers, when survivors and their lawyers typically engage one, whether a licensed investigator can help locate someone who has fled with a child, what lawful surveillance and documentation looks like at a high level, and how the work fits alongside a lawyer, police, and a survivor’s safety plan.

What does a domestic abuse private investigator do in Ontario

A domestic abuse private investigator in Ontario is a PSISA-licensed investigator retained to lawfully document evidence relevant to family violence, defined under Section 2(1) of the Divorce Act as any conduct — whether or not it constitutes a criminal offence — by a family member toward another that is violent, threatening, or that forms a pattern of coercive and controlling behaviour, including physical, sexual, psychological, and financial abuse, and harm to a child’s pets or property.

Under Section 6 of Ontario’s Private Security and Investigative Services Act, 2005 (PSISA), only a person holding a valid provincial licence may act as, or hold themselves out as, a private investigator, including one retained to document domestic abuse. Conducting investigative work for remuneration without that licence is an offence. Sections 45(1) and 45(2) of the PSISA set the penalty for unlicensed work. An individual convicted faces a fine of up to $25,000, up to one year’s imprisonment, or both; a corporation faces a fine of up to $250,000. That is a statutory penalty, not a service rate, and it is a reasonable prompt to confirm a PI’s PSISA licence number before retaining anyone for domestic-abuse-related work. The role does not include giving legal advice, acting as your lawyer, or substituting for police in an emergency; those functions belong to a family lawyer, the courts, and police services.

This licensing requirement exists to protect survivors: domestic-abuse investigations often involve sensitive personal information, and the licence requirement means the investigator has met provincial screening standards and is accountable to a regulator if an engagement goes wrong. A domestic abuse private investigator is also often confused with a bodyguard or a process server; those are different licensed roles under the same PSISA framework, and they do not typically overlap within a single engagement.

When survivors and their lawyers engage a licensed PI

Family lawyers most often engage a licensed private investigator at these points in a case:

• Before filing a parenting application: under the Divorce Act’s Section 16(3)(j), family violence is a mandatory best-interests factor in a parenting order. Section 16(4) directs the court to weigh its pattern, seriousness, and a child’s exposure. Lawyers often engage a PI early to document a record before the application is filed.
• When parents were never married: Ontario’s Children’s Law Reform Act, R.S.O. 1990, c. C.12, Section 24 applies a parallel best-interests test where there is no divorce proceeding. It gives primary consideration to a child’s physical, emotional, and psychological safety, and it weighs family violence, including coercive and controlling behaviour that need not amount to a criminal offence.
• When a pattern, not one incident, needs to be shown: courts weighing the Section 16(4) factors look for frequency and repetition. Lawyers often retain a PI to observe and document conduct over time rather than a single event.

In each of these scenarios, timing matters: a documented pattern built before a parenting application is filed carries more weight than reconstructing events afterward from memory. That is one reason family lawyers loop in a licensed investigator early rather than waiting until a hearing date is already set.

Locating an abuser or a parent who has fled with a child

When an abuser or a parent has left an Ontario address, a licensed PI’s locate work and police powers operate on two different tracks:

• What a licensed PI can lawfully do: conduct open-source and public-record searches, interview consenting witnesses, and coordinate findings with your family lawyer. This falls within the licensed investigative activity Section 6 of the PSISA permits, provided the investigator does not intercept private communications or trespass to gather information.
• What only police can do: Ontario’s Missing Persons Act, 2018, S.O. 2018, c. 3, Sched. 7 gives police officers, not private investigators, the power to make an urgent written demand for records from third parties in time-sensitive cases. It also lets police enter a missing person into CPIC, the national database every Canadian police service can search.
• Why coordination matters: a licensed PI’s locate work operates entirely outside that police-only framework. Filing a police report alongside any PI engagement remains essential whenever a fled parent’s safety or whereabouts may be urgent.

Findings from a locate investigation are typically folded into the same best-interests analysis courts apply under Divorce Act Section 16(4) or CLRA Section 24: where the parent or child is located, and what the circumstances of the departure suggest about risk, both become part of the evidentiary record your lawyer builds. If the fled parent’s location suggests an urgent safety risk to the child, that information is shared with police immediately rather than held until the investigation is complete.

What lawful surveillance and documentation looks like at a high level

At a high level, lawful surveillance and documentation in a domestic-abuse file follows several boundaries:

• One-party consent recording: under Section 184(1) of the Criminal Code, it is generally an offence to intercept a private communication. Section 184(2)(a) creates an exception where the person intercepting has the consent of the originator or the intended recipient. This is why a survivor can lawfully record their own conversation with an abusive partner, and why a licensed PI cannot record a conversation between two other people who have not consented.
• A necessity-and-proportionality standard: the Office of the Privacy Commissioner of Canada’s guidance on covert video surveillance sets a four-part test that PI industry practice treats as the best-practice standard: a demonstrable evidentiary need beyond mere suspicion, a purpose tied to a legitimate objective, proportionality between the privacy loss and the benefit gained, and confirmation that less-invasive alternatives were considered first.
• Limited weight for surreptitious recordings in family court: in Sordi v. Sordi, 2011 ONCA 665, the Court of Appeal for Ontario upheld a trial judge’s discretion to exclude a spouse’s surreptitiously recorded conversation, applying a case-by-case balancing test. In practice, a documented pattern of lawful evidence generally carries more weight in Ontario family court than a single covert recording.
• No spousal exception: Canadian law has no special surveillance rule for spouses or intimate partners. GPS tracking, covert recording, and PI-conducted observation are governed by the Criminal Code, PIPEDA, and the PSISA the same way for everyone. For the full province-by-province boundary, see spousal surveillance laws in Canada.

None of these boundaries changes based on the relationship between the parties; a spouse or partner is treated the same as any other subject of a lawful investigation. Documentation follows the same rules regardless of format: photographs, video, GPS logs, and written observation notes are all subject to the same one-party consent and necessity-and-proportionality boundaries described above.

How a PI works alongside your lawyer, police, and your safety plan

A domestic-abuse investigation is structured to run alongside your existing support team, not around it:

1. Confidentiality and lawful conduct: under O. Reg. 363/07, the PSISA’s Code of Conduct, every licensed investigator must act with honesty and integrity, comply with all applicable federal, provincial, and municipal laws, and treat information received in the course of their work as confidential.
2. Reporting to your lawyer: findings are compiled into a written report, formatted for review by your family-law counsel, rather than delivered as raw field notes.
3. Coordinating with police: any immediate safety concern discovered during an investigation is directed to police, not investigated independently by the PI.
4. Fitting into your safety plan: the investigation is designed to run alongside an existing safety plan, never as a replacement for one.
5. Document retention and follow-up: reports and supporting records are retained and available for follow-up requests from your lawyer as a case progresses, including subsequent court dates or settlement negotiations.

As licensed PSISA investigators conducting domestic violence investigations in Ontario, our practice on a domestic-abuse file is to document only what can be lawfully observed and preserved: dated notes, chain-of-custody records, and a written report formatted for your family lawyer. Any immediate safety concern is directed to police and to your existing safety plan; investigative work is never a substitute for either. Engagement scope and duration vary by case, and any timeline is confirmed in writing once the investigation begins.

What this means for you: safety first, then support

If you are experiencing domestic abuse, safety planning comes before evidence-gathering. Under Section 264 of the Criminal Code, repeatedly following, watching, or communicating with a person in a way that causes them to reasonably fear for their safety is criminal harassment, regardless of intent to gather evidence. This is why a survivor should never attempt their own surveillance of an abuser to build a case. That work should go to a licensed investigator operating within the law, alongside police and a family lawyer, with safety planning coming first.

A licensed private investigator’s role in a domestic-abuse matter is narrow and specific: lawfully gathering and documenting evidence that supports your lawyer’s case and your own safety planning. This work does not promise a particular custody, protection-order, or legal outcome, and it is never a substitute for calling police in an emergency or for an existing safety plan. It is one input among several that a survivor’s broader support team weighs. Every engagement begins with a confidential intake conversation to confirm scope, lawful boundaries, and how findings will support your existing safety plan and legal file.
