Workplace investigations in Ontario help employers establish facts when harassment, theft, fraud, policy breaches, or safety concerns arise. Done poorly, they create legal risk and damage trust. Done well, they document what happened, protect people, and support fair decisions. This guide explains when to investigate, how a licensed private investigator supports the process in Toronto and the GTA, and what a defensible file usually includes.

When a workplace investigation is needed
Start an investigation when allegations or indicators are serious enough that informal conversation is not enough. Common triggers include:
- Harassment, discrimination, or violence complaints
- Theft, inventory loss, expense fraud, or cash irregularities
- Misuse of systems, confidential data, or company assets
- Safety or policy breaches that could harm people or the business
- Conflicts where internal bias would undermine credibility
In Ontario, employers also have duties under occupational health and safety and human rights frameworks to take certain complaints seriously. Counsel should advise on your exact obligations for the file type.
Why companies in Toronto hire an external investigator
Internal HR can handle many routine matters. External help is useful when:
- The allegation involves senior staff or HR itself
- You need independence for board, insurer, or counsel review
- Evidence may include surveillance, skip tracing, or open-source research beyond typical HR tools
- You want a clear written record prepared by investigators used to documenting facts
A licensed PI under the Private Security and Investigative Services Act, 2005 (PSISA) gathers information lawfully. That is different from an employer’s policy decision after the facts are known.
How workplace investigations typically proceed
- Intake and scope: Clarify the allegation, parties, timelines, and what “done” looks like for HR or counsel.
- Plan: Identify witnesses, documents, systems, and any field work required. Set confidentiality expectations.
- Evidence and interviews: Collect records you are entitled to review, conduct structured interviews, and avoid coaching witnesses.
- Analysis: Compare accounts against documents and observations. Note gaps without speculation.
- Report: Deliver a clear summary of methods, findings, and limitations suitable for decision-makers.
Methods must stay lawful. Illegal access to private accounts, trespass, or unlawful recording can destroy usefulness and create liability.
Ontario and GTA practical notes
Toronto workplaces often mix office, warehouse, retail, and hybrid remote setups. Evidence may sit in email, access logs, CCTV, and shift schedules across Mississauga, Scarborough, Markham, and downtown sites. Multi-location employers should define geographic scope early so investigators do not burn hours on the wrong site.
For undercover or discreet observation needs tied to theft or policy breaches, discuss feasibility and legality up front. Not every allegation requires surveillance.
How this differs from a written investigation policy
A policy explains how your organization will respond in general. An investigation is the live file. If you need a policy framework rather than a live case, see our guide on an effective policy for workplace investigations. For insider risk focused on access abuse and corporate security, see internal threat investigation for corporate security.

What a useful investigation report includes
- Scope and mandate agreed at intake
- Timeline of steps taken
- Evidence reviewed and people interviewed
- Findings stated as facts observed or documents show, not motives invented
- Limitations and what could not be verified
Your counsel may ask for a format that supports employment or civil decisions. Tell us that requirement at the start.
Workplace investigations FAQs
What are workplace investigations?
They are structured processes to establish facts about alleged misconduct or risk at work, usually through interviews, document review, and other lawful methods.
Do I need a private investigator for every complaint?
No. Many matters stay with HR. Use an external investigator when independence, specialized evidence, or heightened risk makes an internal-only process weak.
Are workplace investigations in Ontario different from other provinces?
Employment and safety rules vary by jurisdiction. Ontario employers should align the process with local legal advice, privacy expectations, and any applicable policies or collective agreements.
How long does a workplace investigation take?
Simple files may resolve in days. Multi-witness or multi-site matters take longer. Scope and cooperation drive the timeline more than a fixed template.
Will the investigator decide discipline?
Usually no. Investigators report findings. Management and counsel decide employment outcomes.
Can employees refuse to participate?
Participation rules depend on role, policy, and legal advice. Investigators document who cooperated and what was available either way.
