Workplace Investigation Lawyers for Toronto Employers
Under the Occupational Health and Safety Act, Toronto employers are required to investigate workplace harassment complaints promptly and thoroughly. The quality of that investigation, and whether it meets the standard expected by Ontario courts and tribunals, has a direct impact on the employer's legal exposure in any subsequent proceedings before the Human Rights Tribunal of Ontario, the Ontario Labour Relations Board, or a civil court.
A workplace investigation that is conducted too quickly, without proper procedure, or by someone without appropriate independence creates significant risks for Toronto employers. If the investigation process is later found to have been inadequate, the employer loses the benefit of having investigated at all and may face adverse findings that a proper investigation could have avoided.
Achkar Law's Toronto workplace investigation lawyers provide independent investigation services and legal advice to employers across the city and GTA. We conduct investigations that meet the legal and procedural standards expected by Ontario adjudicators, produce defensible written reports, and advise on the remediation steps that follow.

Types of Workplace Complaints That Require Investigation in Toronto
Toronto employers face investigation obligations across a range of workplace situations. Understanding when an investigation is legally required and what standard it must meet is critical to managing employer risk effectively.
Workplace Harassment Complaints
Under the Occupational Health and Safety Act, Ontario employers with a written harassment policy are required to investigate complaints of workplace harassment. The investigation must be conducted in an objective and timely manner. Toronto employers who fail to investigate harassment complaints, or whose investigations are found to be inadequate, face significant exposure before the Ministry of Labour and in related legal proceedings.
Sexual Harassment Complaints
Sexual harassment complaints in Toronto workplaces engage obligations under both the Occupational Health and Safety Act and the Ontario Human Rights Code. These complaints require particularly careful investigation given the sensitivity of the subject matter, the significant damages available through the Human Rights Tribunal of Ontario, and the evidentiary standards applied by HRTO adjudicators when assessing the adequacy of the employer's response.
Workplace Violence Incidents
Workplace violence incidents or threats in Toronto require immediate employer response including investigation of what occurred, assessment of ongoing risk, and implementation of appropriate measures to protect employees. Under the Occupational Health and Safety Act, employers have specific obligations following workplace violence incidents that extend beyond simply taking disciplinary action against the individual involved.
Discrimination Complaints
When a Toronto employee raises a complaint of discrimination based on a protected ground under the Ontario Human Rights Code, the employer's response, including whether a proper investigation was conducted, is scrutinized by the Human Rights Tribunal of Ontario. An inadequate response to a discrimination complaint can result in adverse findings and significantly higher damage awards than the underlying conduct alone would attract.
Misconduct and Disciplinary Investigations
When Toronto employers are considering discipline or termination based on employee misconduct, a properly conducted investigation creates the evidentiary record needed to support the disciplinary decision. In just cause termination cases, the adequacy of the pre-termination investigation is a key factor assessed by courts and arbitrators when determining whether the employer's decision was reasonable and proportionate.
Conflict of Interest and Fraud Investigations
When allegations of conflict of interest, fraud, theft, or other serious misconduct arise in a Toronto workplace, employers need an investigation that meets a higher evidentiary standard given the potential for civil and criminal proceedings. Achkar Law's Toronto workplace investigation lawyers advise on the appropriate scope and procedure for serious misconduct investigations and produce reports designed to withstand legal scrutiny.
The Standards Ontario Courts and Tribunals Apply to Workplace Investigations
Ontario courts and tribunals assess the adequacy of workplace investigations based on a set of well-established procedural and substantive standards. Toronto employers whose investigations meet these standards are in a significantly stronger position in any resulting legal proceedings.
Independence of the Investigator
The investigator must be independent from the parties and the subject matter of the complaint. For many Toronto employers, this means using an external workplace investigation lawyer rather than conducting the investigation internally. An investigator who has a real or perceived conflict of interest undermines the entire investigation regardless of how well the process was otherwise conducted.
Procedural Fairness
Both the complainant and the respondent must have a fair opportunity to present their account of events and to respond to the information gathered. The investigator must be impartial, must consider all relevant evidence, and must not prejudge the outcome. Failures of procedural fairness are among the most common grounds on which Toronto workplace investigations are challenged in subsequent proceedings.
Thoroughness and Timeliness
The investigation must be thorough, covering all relevant witnesses and documentary evidence, and must be completed in a timely manner. Delays in investigation are both a compliance issue under the Occupational Health and Safety Act and a factor that courts and tribunals consider when assessing whether the employer took the complaint seriously.
A Written Report with Clear Findings
The investigation must be documented in a written report that sets out the complaint, the process followed, the evidence gathered, the credibility assessments made, and the findings. A well-drafted investigation report is the employer's primary protection in any subsequent challenge to the investigation process or outcome.
Appropriate Remediation
Where harassment or misconduct is found, the employer must take appropriate corrective action. The response must be proportionate to the findings and must be implemented promptly. An investigation that produces findings but no meaningful remediation provides limited protection to the Toronto employer in subsequent proceedings.
Many Toronto employers attempt to conduct harassment or misconduct investigations internally, using HR personnel or senior management. While this may seem like the most efficient approach, internal investigations frequently create problems that external independent investigations avoid entirely.
An internal investigator may be perceived as biased toward the employer, particularly by the complainant and by adjudicators assessing the process. A senior HR professional or manager may not have the legal knowledge to conduct the investigation in a way that meets the standards applied by Ontario courts and tribunals. And an investigation conducted by someone who continues to have a working relationship with the parties creates ongoing awkwardness regardless of the outcome.
Achkar Law's Toronto workplace investigation lawyers bring full independence, legal knowledge of the applicable standards, and experience producing investigation reports that withstand scrutiny in subsequent proceedings. Our investigations integrate directly with our workplace policies and employer defence practices to provide complete employer-side legal support.
Speak With a Toronto Workplace Investigation LawyerWhat a Toronto Workplace Investigation Lawyer Does for Your Organization
Achkar Law's Toronto workplace investigation lawyers assist employers at every stage of the investigation process, from initial complaint intake through to report, remediation, and any resulting legal proceedings.
Advise on Investigation Scope and Process
When a complaint is received, we advise on the appropriate scope of the investigation, the process to be followed, and any immediate steps the employer should take pending investigation, including interim measures to protect the complainant if warranted. Getting advice at the very start of the process prevents the procedural errors that most commonly undermine workplace investigations in Toronto.
Conduct the Independent Investigation
We conduct the investigation as independent external investigators, interviewing all relevant witnesses, reviewing documentary evidence, and assessing credibility where accounts conflict. Our investigators understand the legal standards applied by Ontario courts and tribunals and conduct every investigation with those standards in mind from the outset.
Produce a Legally Defensible Written Report
We produce a comprehensive written investigation report setting out the complaint, the investigation process, the evidence gathered, credibility assessments, and clear findings on each allegation. The report is drafted to withstand legal scrutiny and to provide the Toronto employer with a defensible record of how the complaint was handled.
Advise on Remediation and Next Steps
Following the investigation, we advise the employer on appropriate remediation steps, including disciplinary action where findings support it, policy or process changes to prevent recurrence, and how to communicate the outcome to the parties. We also advise on managing any ongoing risk of legal proceedings arising from the complaint and investigation.
Defend the Investigation in Subsequent Proceedings
If the complainant or respondent challenges the investigation in subsequent legal proceedings, we advise on defending the investigation process and findings before the Human Rights Tribunal of Ontario, the Ontario Labour Relations Board, or a civil court. See our Ontario workplace investigations page and our Toronto employer defence page for more on our broader employer-side legal services.

Workplace Investigation Lawyer Toronto: Common Questions
Common questions from Toronto employers about workplace investigations. Contact us directly if your situation is not covered here.
Speak With a Toronto Investigation LawyerYes. Under the Occupational Health and Safety Act, Ontario employers are required to investigate workplace harassment complaints in an objective and timely manner. Toronto employers must have a written workplace harassment policy that sets out the investigation procedure, and must follow that procedure when a complaint is received. Failure to investigate, or an investigation that is found to be inadequate, exposes the employer to Ministry of Labour enforcement action and significantly weakens its position in any subsequent human rights or civil proceedings.
Toronto employers can conduct investigations internally, but internal investigations carry significant risks. An internal investigator may lack the independence required for a defensible investigation, may not have the legal knowledge to meet the procedural standards applied by Ontario courts and tribunals, and may create the perception of bias regardless of how fairly the investigation is actually conducted.
For complaints involving senior employees, situations where the alleged harasser is in a position of authority, or matters likely to result in legal proceedings, using an independent external workplace investigation lawyer is strongly advisable. The cost of an independent investigation is almost always significantly lower than the cost of defending a challenge to an inadequate internal investigation.
Ontario courts and tribunals assess workplace investigations against several key standards. The investigator must be independent and impartial. Both parties must have a fair opportunity to present their account and respond to the evidence against them. The investigation must be thorough, covering all relevant witnesses and documents. It must be completed in a timely manner. And the findings must be documented in a written report that clearly sets out the process, the evidence, and the conclusions.
Toronto employers whose investigations meet these standards are in a significantly stronger position in any subsequent legal challenge. Achkar Law's workplace investigation lawyers conduct investigations designed to meet these standards from the outset.
The duration of a workplace investigation in Toronto depends on the complexity of the allegations, the number of witnesses involved, the volume of documentary evidence, and the availability of the parties. A straightforward harassment complaint with a small number of witnesses may be completed within a few weeks. More complex investigations involving multiple complainants, extensive documentary records, or serious allegations may take longer.
Timeliness is a legal requirement under the Occupational Health and Safety Act, and employers should not delay the start of an investigation once a complaint is received. Achkar Law's Toronto workplace investigation lawyers prioritize prompt investigation commencement and efficient completion without compromising the thoroughness required for a defensible process.
Where a Toronto workplace investigation finds that harassment occurred, the employer must take appropriate corrective action proportionate to the findings. This may include disciplinary action up to and including termination of the respondent, policy changes, training requirements, or other remediation measures. The employer must also consider the ongoing safety and wellbeing of the complainant and take steps to prevent recurrence.
The adequacy of the remediation response is assessed by Ontario courts and tribunals alongside the investigation itself. Achkar Law's Toronto workplace investigation lawyers advise on appropriate remediation following investigation findings, including the disciplinary and legal implications of the options available to the employer.
A workplace investigation often sits at the centre of multiple overlapping legal proceedings. The complainant may file an HRTO application, a Ministry of Labour complaint, and potentially a civil claim, all arising from the same underlying conduct. The investigation process and findings become evidence in each of those proceedings. An investigation that meets the required legal standards significantly improves the employer's position across all related proceedings.
Achkar Law's Toronto workplace investigation lawyers work alongside our employer defence team to ensure the investigation is conducted in a way that supports the employer's position in all related legal proceedings, not just the investigation itself.
