What is a workplace investigation?
A workplace investigation is an employer-led fact-finding process used to assess workplace complaints or allegations connected to workplace conduct. In Toronto workplaces, investigations most often involve allegations of harassment, discrimination, bullying, sexual harassment, violence, or breaches of workplace policies and codes of conduct.
Conducting workplace investigations can be fair and necessary, but they can also be mishandled, incomplete, or used to support a disciplinary outcome the employer has already decided on. When your reputation and employment are on the line, you should treat the process as a serious legal event, not an HR formality.
What can cause a workplace investigation?
A workplace investigation process is only undertaken when an employer becomes aware of alleged misconduct, including:
- sexual harassment
- workplace violence, including harassment and bullying
- discriminatory conduct or human rights violations
- violations of workplace policies or codes of conduct
- conflicts of interest or other unethical behavior
- any other form of perceived wrongdoing or conduct violations

What is the purpose of a workplace investigation?
The point of workplace investigations is to gather enough reliable information for the employer to decide what happened and what response is appropriate. That typically involves interviewing the complainant and respondent, speaking to witnesses, and reviewing relevant records such as emails, messages, calendars, security footage, or internal documentation.
A proper investigation is about evidence and fairness. It should test both sides of the story, not just confirm the employer’s preferred narrative. For employers, the outcome may guide corrective action, training, policy changes, or discipline. For employees, the findings can affect job security, future prospects, personal credibility, and even introduce potential legal liability.
What can you expect to happen in a workplace investigation?
While every Toronto workplace is different, a typical investigative process includes:
- Commencement:
A complaint is raised or an incident is reported - Notification:
You should be told an investigation is underway and given enough detail to respond meaningfully - Investigator Appointed:
The employer appoints an internal investigator or an external investigator - Fact Gathering:
The investigator gathers pertinent documentation and other evidence, including interviewing witnesses and any other parties involved - Analysis and Report:
The investigator analyzes the evidence and prepares findings and recommendations - Employer Action:
The employer decides what action to take and communicates the result in an appropriate way. The employer may also include follow up steps to confirm that the issue has been resolved or to stop similar events from occurring in the future.

What are employee rights in a workplace investigation?
Your specific rights may be shaped by your employment agreement, workplace policies, and whether you are unionized. Even so, certain fairness expectations apply in practice, especially where the outcome could lead to discipline or termination.
In most investigations, you should expect:
- timely notice of the allegation and a fair chance to respond
- a process that is reasonably impartial and appropriate in the circumstances
- confidentiality to the extent possible, recognizing there are practical limits
- freedom from retaliation for participating in the process
- clarity on the outcome and what it means for you going forward
Employers are required to maintain procedural fairness and avoid any form of retaliation when conducting workplace investigations. You are also legally protected against discriminatory harassment and wrongful dismissal as per Ontario workplace laws and the Canadian Human Rights Tribunal guidelines.
How should you behave during a workplace investigation?
A good approach is disciplined and factual. Your goal should be to remain professional while asserting your rights without creating new issues:
- Stay professional in tone and conduct, including outside interviews
- Cooperate with reasonable requests from workplace investigators, but do not guess or fill gaps with assumptions
- Focus on facts, timelines, documents, and what you personally observed
- Keep the matter as confidential as you reasonably can
- Preserve relevant records (emails, messages, notes, schedules)
- Take your time answering questions, it is acceptable to say you do not know
- Do not retaliate or engage in “side conversations” that can be misinterpreted

How can a Toronto workplace investigation lawyer from Whitten & Lublin help you?
When you are named in a workplace investigation, the process is already shaping the record. Notes get taken, timelines get built, and credibility gets assessed. What you say in an interview, what you hand over, and what you do between meetings can end up driving the outcome.

We review the allegation and the employer’s investigation steps, identify what you should and should not be answering, and help you prepare for interviews so you are clear, factual, and consistent. We also help you gather and preserve the documents that matter, emails, messages, schedules, performance records, and anything that puts events in context.
If the investigation feels slanted or designed to justify discipline, we address that directly. Where appropriate, we communicate with the employer or investigator on your behalf, set boundaries around the process, and ensure your rights are respected.

Toronto workplace investigations are shaped by the kind of workplace you are in and what the complaint is about. If you work for a provincially regulated employer, Ontario’s Occupational Health and Safety Act sets expectations around investigating workplace harassment and violence. If you are in a federally regulated workplace, such as banking, telecom, air and rail, the Canada Labour Code and its harassment and violence framework apply.
Where the allegation involves discrimination, the Ontario Human Rights Code (or the Canadian Human Rights Act for federally regulated workplaces) also matters. Those laws do not just prohibit discrimination, they influence what a fair process looks like when the complaint is connected to protected grounds.
Even when a statute does not spell out every step, common law and principles of procedural fairness still matter, especially if the investigation is used to justify discipline or termination. A flawed process is not always a standalone legal claim, but if it leads to discriminatory outcomes, reputational harm, or a bad-faith dismissal, it can become legally significant. That is where early legal advice can protect your rights and prevent the employer from treating “investigation” as a shortcut to a predetermined result.
Most investigations start with a complaint, a report to HR, or a manager being told something happened. From there, the employer decides whether the issue requires a formal investigation and appoints someone to run it.
You should be told you are being investigated and given enough detail to respond meaningfully. That does not always mean every document is shared at the outset, but it does mean you should understand what is being alleged, the timeframe, and the nature of the complaint.
They are meant to be handled discreetly, but confidentiality has limits. Employers still have to interview witnesses, gather records, and communicate with decision-makers. That means information will circulate inside a smaller group, even when everyone is told to keep it private.
As an employee, the safest approach is to avoid discussing the investigation at work, including informal chats, texts, Slack messages, or “clearing the air” conversations with coworkers. Those communications can become evidence, and they are easily framed as interference or retaliation, even when that was not your intent. If you need support, you can trust a workplace investigation lawyer to keep things confidential.
An investigation can be run internally, often by HR or management, or externally by a third-party investigator. Toronto employers often bring in an external investigator where allegations are serious, senior people are involved, or the employer wants distance from the process.
Internal investigations can be appropriate, but they raise obvious concerns when the investigator has relationships in the workplace or the outcome has already been informally discussed. External investigations can be more neutral in theory, but they still need to be properly scoped, fair, and evidence-driven.
If the investigator seems biased, the questions are leading, or the process is being used to build a case for discipline, legal advice can help you respond without giving away ground. The goal is not to obstruct an investigation. It is to make sure it is conducted fairly, and that the findings are not built on guesswork, selective evidence, or a one-sided narrative.
