Can a Private Investigator Help With Landlord-Tenant Disputes?
Landlord-tenant disputes can quickly become stressful, expensive, and difficult to resolve—especially when there are conflicting accounts of what actually happened.
Whether you’re a landlord trying to recover unpaid rent or a tenant who believes they’ve been served with a bad-faith eviction notice, strong evidence is often the difference between suspicion and proof.
This is where a licensed private investigator can help.
Private investigators do not make legal decisions or replace lawyers, but they can legally gather factual evidence that may assist landlords, tenants, lawyers, or paralegals in preparing for proceedings before the Ontario Landlord and Tenant Board (LTB) or other civil matters.
In this guide, we’ll explain the types of landlord-tenant investigations private investigators perform, when they’re appropriate, and how professionally collected evidence can strengthen a case.

When Should You Hire a Private Investigator?
Many landlord-tenant disagreements come down to one question:
Can it be proven?
A private investigator can help when reliable evidence is needed to support or challenge a claim.
Common situations include:
- Suspected bad-faith N12 notices
- Locating former tenants who owe money
- Confirming where someone currently lives
- Verifying whether a landlord has actually moved into a property
- Confirming occupancy after an eviction
- Workplace investigations for judgment enforcement
- Documenting unauthorized occupants or suspected illegal subletting
- Collecting evidence for civil litigation
The goal is not to “catch” someone doing something wrong—it is to document the facts objectively and lawfully.How Private Investigators Help Landlords
Landlords often contact private investigators after obtaining an LTB order or when they suspect lease violations.
Locating Former Tenants
One of the most common requests is locating tenants who have moved without leaving a forwarding address.
Professional skip tracing may involve reviewing publicly available records, investigative databases, and other lawful resources to identify a current address.
Workplace Surveillance for Judgment Enforcement
If a landlord has obtained a judgment but does not know where a former tenant works, workplace surveillance may help confirm employment.
This information can assist legal professionals pursuing wage garnishment or other enforcement options where permitted by law.
Move-Out Surveillance
Move-day investigations can help confirm when a tenant has vacated a property and, in some cases, identify the location where belongings are being moved.
This information can be valuable when time is critical.
How Private Investigators Help Tenants
Private investigators also work for tenants.
If a tenant believes a landlord has acted improperly, professional surveillance may help document what is actually happening after an eviction.
Confirming Occupancy After an N12 Notice
An N12 notice requires the landlord (or an eligible family member) to genuinely move into the property.
If there are concerns that the property has instead been rented to new tenants or listed for sale shortly after the eviction, surveillance and other investigative techniques may help document what occurred.
Investigators may lawfully observe occupancy from public places, document activity, and gather evidence relevant to the issue.

Common Investigation Services
Every landlord-tenant dispute is different, but some of the most requested investigative services include:
Surveillance
Professional surveillance can document:
- Occupancy
- Property use
- Visitor activity
- Move-ins and move-outs
- Business activity where relevant
Skip Tracing
Skip tracing helps locate individuals who have relocated without providing updated contact information.
Background Investigations
Depending on the circumstances and applicable laws, background investigations may provide useful information during civil disputes.
Workplace Verification
Where legally appropriate, workplace surveillance may confirm employment for judgment enforcement purposes.
Evidence Collection
Investigators may document:
- Photographs
- Video
- Time-stamped observations
- Witness interviews (where appropriate)
- Publicly available records
- Written investigative reports
All evidence should be collected lawfully and ethically.
What Evidence Can Be Collected?
Private investigators focus on factual observations rather than opinions.
Depending on the assignment, evidence may include:
- Surveillance photographs
- Video recordings
- Dates and times of observations
- Written reports
- Property observations
- Occupancy documentation
- Public records research
- Statements from willing witnesses
This information can often assist legal counsel or paralegals when preparing for hearings.
Legal Considerations
Licensed private investigators in Ontario must comply with the Private Security and Investigative Services Act (PSISA) and all applicable privacy laws.
Investigators cannot:
- Trespass onto private property without authorization.
- Access private financial records without legal authority.
- Wiretap or intercept private communications.
- Install hidden cameras in places where people have a reasonable expectation of privacy.
- Harass or intimidate individuals.
Professional investigations rely on lawful surveillance, careful documentation, and objective reporting.
