Workplace Investigations for Ontario Employers
Workplace Investigation Lawyers Serving Employers Across Ontario
Workplace complaints require prompt, careful and fair attention. Allegations of harassment, sexual harassment, discrimination, workplace violence, reprisal, bullying, misconduct or a poisoned work environment can affect employee safety, workplace morale, business operations and legal risk.
Vanguard Law assists Ontario employers with workplace investigations and related employment-law advice. We conduct external workplace investigations, advise employers managing internal investigations, assist with investigation planning and documentation, and provide guidance concerning next steps following findings.
Whether your organization has received a formal complaint, become aware of serious workplace conduct or requires an external investigator, timely legal advice can help you establish an appropriate process and respond responsibly.

When Ontario Employers May Need a Workplace Investigation
Ontario employers may need to investigate workplace complaints or incidents involving harassment, sexual harassment, violence, discrimination, reprisal or other serious workplace misconduct.
A workplace investigation may be required or advisable where:
An employee reports workplace harassment or sexual harassment;
A manager receives a complaint about bullying, intimidation or inappropriate conduct;
An employee alleges discrimination, accommodation failures or a poisoned work environment;
There are allegations of reprisal after an employee raised concerns;
A complaint involves workplace violence, threats or safety concerns;
A complaint is made against a supervisor, executive, owner or human resources representative;
Multiple employees raise concerns about the same conduct or workplace culture;
An anonymous complaint raises potentially serious allegations;
Misconduct allegations may lead to discipline or termination; or
An employer requires an impartial review of conflicting accounts or sensitive evidence.
A properly structured investigation can help an employer understand what occurred, address workplace concerns, make informed decisions and reduce the risk created by an incomplete or unfair process.

External Workplace Investigations
An external workplace investigation may be appropriate where independence, neutrality, confidentiality or specialized employment-law experience is particularly important.
Vanguard Law conducts external workplace investigations for Ontario employers. We assist organizations with gathering and assessing relevant information, interviewing participants, reviewing documentary evidence and preparing findings based on the applicable standard of proof.
An external investigator may be appropriate where:
The complaint involves a senior manager, executive, owner or human resources professional;
Internal impartiality may reasonably be questioned;
The allegations are serious, sensitive or complex;
Multiple employees or competing accounts are involved;
The complaint may lead to discipline, termination, litigation, arbitration or a tribunal proceeding;
The employer lacks an internal investigator with appropriate experience or availability; or
The organization requires a structured and documented process.
Our investigation process is designed to gather relevant evidence fairly, provide participants with an appropriate opportunity to be heard and deliver clear findings to assist the employer with next steps.
Advice for Employers Conducting Internal Investigations
Not every workplace complaint requires an external investigator. Depending on the allegations, workplace structure and available internal resources, an employer may conduct an investigation internally.
However, internal investigations still require thoughtful planning and procedural fairness. Employers should consider who will investigate, what issues are within scope, how evidence will be collected, how participants will be interviewed, what confidentiality expectations apply and how findings will be documented.
Vanguard Law advises employers conducting internal investigations, including by assisting with:
Determining whether an internal investigation is appropriate;
Reviewing workplace harassment, violence and complaint policies;
Identifying the allegations requiring investigation;
Developing Terms of Reference;
Preparing an investigation plan;
Identifying relevant documents and witnesses;
Developing interview questions;
Addressing accommodation, confidentiality and reprisal concerns;
Reviewing investigation documentation or draft reports; and
Advising on post-investigation decisions.
Employers requiring recurring support for workplace policies, investigation procedures and day-to-day employment-law issues may benefit from Workplace Counsel+™.
Workplace Harassment and Sexual Harassment Investigations
Workplace harassment complaints may involve repeated comments or conduct, bullying, humiliating treatment, offensive messages, inappropriate workplace interactions or behaviour alleged to create an unsafe or hostile work environment.
Sexual harassment complaints may involve unwanted comments, communications, touching, advances, conduct involving workplace power dynamics or allegations of reprisal following rejected conduct or a complaint.
When an employer becomes aware of allegations of workplace harassment or sexual harassment, it is important to assess the complaint promptly and determine an investigation process appropriate to the circumstances.
We assist employers with workplace harassment and sexual harassment investigations involving:
Complaints between employees;
Complaints involving supervisors or managers;
Allegations involving executives or business owners;
Digital communications, emails, text messages or workplace messaging platforms;
Workplace events, travel or off-site conduct connected to employment;
Reprisal concerns following a complaint; and
Complaints that may affect continued employment or workplace safety.
Discrimination and Human Rights-Related Complaints
Workplace investigations may involve allegations connected to disability, sex, race, age, family status, creed, gender identity, gender expression, sexual orientation or another protected ground under Ontario human rights law.
These matters may raise issues relating to accommodation, differential treatment, discriminatory harassment, reprisal or a poisoned work environment.
Vanguard Law assists employers with investigating and responding to workplace complaints involving:
Alleged discriminatory comments or conduct;
Accommodation-related disputes;
Disability and return-to-work concerns;
Allegations of unequal treatment;
Harassment connected to a protected ground;
Reprisal following a human rights complaint; and
Complaints arising alongside performance management, discipline or termination decisions.
Employers should assess these complaints carefully, particularly where workplace decisions and human rights concerns overlap.
Workplace Violence, Threats and Safety Concerns
Allegations involving threats, physical altercations, intimidation, escalating interpersonal conflict or other safety risks may require urgent action in addition to an investigation.
Employers may need to consider interim workplace measures while gathering information and ensuring that the investigation process does not create additional risk to employees or operations.
We assist employers with investigating matters involving:
Threatening statements or conduct;
Alleged physical incidents;
Serious workplace conflict;
Safety-related complaints;
Concerns about continued workplace interaction; and
Complaints requiring interim measures while facts are investigated.
Reprisal and Whistleblower Complaints
A workplace complaint may include allegations that an employee was treated negatively after reporting misconduct, harassment, discrimination, safety concerns or other workplace issues.
Reprisal allegations can arise after changes to duties, discipline, reduced hours, exclusion, negative treatment, suspension, termination or other workplace action following a complaint.
We assist employers with investigating:
Whether a protected complaint or workplace concern was raised;
What workplace decisions followed;
The stated reasons for those decisions;
Relevant communications and documentation; and
Whether the reprisal allegation should be addressed alongside the original complaint.
Misconduct and Policy-Breach Investigations
Workplace investigations are not limited to harassment complaints. Employers may also need to investigate alleged misconduct affecting trust, safety, workplace standards or business operations.
These matters may involve:
Dishonesty or misrepresentation;
Breaches of confidentiality;
Conflicts of interest;
Insubordination;
Misuse of company property or systems;
Breaches of workplace policies;
Code of conduct violations;
Inappropriate workplace communications;
Attendance or time-record concerns; or
Other serious misconduct allegations.
Where investigation findings may lead to discipline or termination, employers should consider obtaining legal advice before making a final decision.
If a terminated employee later challenges the employer’s decision or seeks additional compensation, Vanguard Law also assists employers through its Wrongful Dismissal Defence service.
Complaints Involving Managers, Executives or Business Owners
Complaints against managers, senior leaders, owners or human resources personnel can be particularly sensitive.
These matters may involve power imbalances, concerns about employee participation, reputational risk, confidentiality issues and questions about whether an internal investigator can be sufficiently impartial.
An external workplace investigation may help an employer establish a more independent process where:
The respondent has authority over the complainant or witnesses;
Human resources staff are directly involved in the allegations;
Internal reporting structures make neutrality difficult;
The allegations concern organizational culture or senior leadership; or
The employer anticipates that the process or findings may later be scrutinized.
Vanguard Law helps employers establish and carry out an appropriate investigation process in these circumstances.
Our Workplace Investigation Process
1. Intake and Preliminary Assessment
We begin by understanding the organization, the nature of the complaint or incident, the individuals involved, any immediate risks and the employer’s objectives.
At this stage, we may consider:
The allegations raised;
Whether urgent interim measures are required;
Whether documents or electronic evidence should be preserved;
Whether an internal or external investigation is appropriate;
Whether accommodation or accessibility needs should be addressed; and
Whether there are related employment-law issues requiring separate advice.
2. Scope and Terms of Reference
A clear investigation mandate helps define the process and reduce uncertainty.
Where appropriate, we prepare or assist with Terms of Reference addressing:
The allegations to be investigated;
The investigator’s role;
The parties and potential witnesses;
The applicable standard of proof;
Confidentiality expectations;
Communication procedures;
Reporting requirements; and
The anticipated investigation process.
3. Document Preservation and Evidence Collection
Relevant documents and communications may become important evidence in a workplace investigation.
Depending on the matter, the employer may need to preserve and review:
Written complaints and responses;
Workplace policies and handbooks;
Emails, text messages and internal messaging-platform communications;
Performance-management or disciplinary records;
Human resources documents;
Schedules, attendance records or meeting notes;
Video, photographs or electronic records, where applicable; and
Other documents identified during interviews.
We help employers identify and organize relevant information while keeping the investigation focused on the allegations within scope.
4. Interviews
Interviews may be conducted with the complainant, respondent and relevant witnesses.
A fair interview process generally provides participants with an opportunity to explain what occurred, identify documents or witnesses and respond to material allegations relevant to the investigation.
We conduct interviews in an organized and respectful manner, with attention to confidentiality, accessibility, accommodation and the integrity of the evidence-gathering process.
5. Analysis and Findings
Following interviews and document review, we assess the available evidence and reach findings using the applicable civil standard of proof: whether the alleged conduct is more likely than not to have occurred.
Our role as external investigator is to assess the evidence fairly and provide clear findings within the defined investigation mandate.
6. Investigation Report
Depending on the scope of the retainer, an investigation report may set out:
The allegations investigated;
The process followed;
The evidence reviewed;
The individuals interviewed;
The applicable standard of proof;
Relevant factual findings; and
Recommendations, where requested and appropriate.
The report is intended to assist the employer with understanding the findings and determining appropriate next steps.
7. Post-Investigation Advice and Workplace Response
After an investigation concludes, an employer may require advice about:
Communicating investigation results appropriately;
Corrective action or discipline;
Termination decisions;
Workplace restoration;
Safety planning;
Policy updates;
Training or manager guidance;
Accommodation or return-to-work issues; and
Responding to threatened litigation or tribunal claims.

What Employers May Receive
Depending on the nature and scope of the engagement, workplace investigation services may include:
Preliminary intake and issue assessment;
Conflict checks;
Terms of Reference;
Investigation planning;
Document request lists;
Evidence organization and review;
Interview invitations and scheduling support;
Interviews of relevant participants;
Investigation notes and evidence records;
Findings report;
Recommendations, where requested and appropriate;
Employer advice following the findings; and
Support concerning related workplace policies or future risk management.
Every investigation is different. The process, timelines and deliverables should reflect the allegations, number of participants, documentary evidence, urgency and needs of the workplace.
Workplace Investigation Timelines and Fees
The time and cost involved in a workplace investigation depend on the scope of the allegations, number of participants, available documentation, interview scheduling, urgency and whether additional issues arise during the process.
A single-issue complaint involving a limited number of witnesses may proceed differently from a matter involving multiple allegations, senior leadership, significant documents or broader workplace concerns.
Vanguard Law discusses scope, process and anticipated fees at the outset of an engagement and can advise on an investigation approach appropriate to the circumstances.
Workplace Policies, Procedures and Prevention
A workplace investigation may reveal broader issues in an employer’s policies, reporting procedures, documentation practices or manager training.
Vanguard Law assists Ontario employers with reviewing and developing:
Workplace harassment and violence policies;
Complaint reporting procedures;
Investigation protocols;
Codes of conduct;
Confidentiality and record-handling procedures;
Manager guidance;
Performance-management and discipline documentation;
Termination planning processes; and
Employment agreements and workplace documentation.
Employers seeking ongoing employment-law support for policies, workplace complaints, discipline, accommodation and termination planning can learn more about Workplace Counsel+™.
Workplace Investigations and Termination Decisions
An investigation may lead an employer to consider discipline, workplace changes or termination. Those decisions should be made carefully, based on the facts, available evidence, applicable policies, the employment agreement and relevant legal obligations.
Termination following a workplace investigation may lead to additional disputes concerning cause, notice, severance, bad faith, reprisal, human rights allegations or the fairness of the investigation process.
Where an employer is responding to a claim arising from a termination, Vanguard Law provides employer-side representation through its Wrongful Dismissal Defence practice.

Frequently Asked Questions for Ontario Employers
Does an Ontario Employer Have to Investigate a Workplace Harassment Complaint?
Ontario employers must ensure that an investigation appropriate in the circumstances is conducted into workplace-harassment complaints or incidents. The appropriate scope and process depend on the nature of the allegations, the individuals involved, available evidence and workplace circumstances.
When Should an Employer Retain an External Workplace Investigator?
An external investigator may be appropriate where the allegations involve senior leadership, internal neutrality may be questioned, the matter is sensitive or complex, multiple parties are involved, or the process may later be reviewed in litigation, arbitration or a tribunal proceeding.
Can an Employer Conduct a Workplace Investigation Internally?
Depending on the matter, an internal investigation may be appropriate where a suitable investigator is available and can conduct a fair process. Employers may still benefit from legal advice regarding scope, documentation, interviews, confidentiality, findings and next steps.
What Types of Complaints Can Be Investigated?
Workplace investigations may involve harassment, sexual harassment, discrimination, reprisal, workplace violence, bullying, policy breaches, dishonesty, conflicts of interest, misconduct or complaints involving managers and senior leadership.
What Standard of Proof Is Used in a Workplace Investigation?
Workplace investigation findings are generally assessed on the balance of probabilities, meaning whether it is more likely than not that the alleged conduct occurred.
What Should an Employer Do Immediately After Receiving a Serious Complaint?
An employer should consider preserving relevant documents, identifying any immediate safety or operational concerns, reviewing applicable workplace policies, avoiding premature conclusions and obtaining advice about an appropriate investigation process.
What if a Complaint Is Made Against a Manager or Owner?
Complaints involving a manager, executive or owner may raise issues concerning power imbalance, employee participation and perceived impartiality. In appropriate circumstances, an external investigator may help establish a fair and independent process.
What if the Investigation Leads to Termination?
Where an investigation leads to termination, the employer should assess the decision carefully, including the evidence, applicable policies, employment agreement and legal obligations. If a claim follows, our Wrongful Dismissal Defence service assists Ontario employers responding to termination disputes.
Can Workplace Investigations Help Reduce Future Risk?
An appropriate investigation can assist an employer with addressing a current complaint and may also identify opportunities to improve policies, reporting procedures, documentation, training and manager support. For recurring employer-side assistance, learn more about Workplace Counsel+™.
