Investigation Reports: What to Include and What to Exclude
0 of 6

The investigation had concluded 4 days earlier, but the report remained unwritten. A mid-sized professional services firm operating out of 3 offices across western Canada found itself at a critical juncture following a complaint filed by a senior administrative coordinator against a regional manager. The complaint alleged a pattern of conduct over approximately 8 months that included inappropriate comments, differential treatment, and 2 specific incidents that the complainant characterized as harassment.

The firm had engaged an external investigator with 15 years of experience in workplace matters. Over a 3-week period, the investigator interviewed 11 witnesses, reviewed 47 email exchanges, examined performance documentation spanning 2 years, and gathered security access records from the office building. Several witnesses corroborated aspects of the complainant's account, while others provided testimony that contradicted key elements. The regional manager denied the allegations and offered alternative explanations for the conduct described. Documentary evidence supported some factual claims but left others unresolved.

The investigator had now provided a verbal summary of preliminary conclusions to the director of human resources but had not yet drafted the formal report. The director faced pressure from multiple directions. Senior leadership wanted the matter resolved quickly and sought clear recommendations about whether discipline was warranted. The complainant had retained legal counsel and made a formal request for a copy of the investigation report. The respondent's union representative had already indicated that any disciplinary action would be grieved and that the investigation methodology would be scrutinized.

The firm's legal counsel had raised questions about litigation privilege and whether the report should be prepared under legal advice to protect certain communications from disclosure. Meanwhile, the human resources team had discovered that an early draft memorandum prepared during the investigation contained speculative commentary about the respondent's credibility that did not reflect the investigator's ultimate assessment—raising concerns about what should happen to preliminary documents.

The director of human resources understood that the written report would need to serve multiple functions simultaneously. It would need to document findings of fact sufficient to support whatever employment decision followed, withstand potential challenge at arbitration or before a human rights tribunal, satisfy disclosure obligations without compromising legitimately privileged material, and communicate outcomes to both parties in a manner that met the firm's legal obligations while preserving workplace relationships to whatever extent remained possible. The investigation had generated substantial evidence and clear analytical conclusions, but translating that work into a defensible written record presented its own distinct challenges.

Findings of Fact: How to Write Conclusions That Will Withstand Scrutiny

Findings of fact represent the foundation upon which every workplace investigation rests. They are the documented conclusions that transform raw evidence, conflicting accounts, and uncertain circumstances into clear determinations about what happened. When an employer terminates an employee for cause, imposes discipline, or decides that no misconduct occurred, the findings of fact in the investigation report are what justify that decision. They are also what arbitrators, human rights tribunals, and courts examine when determining whether the employer acted reasonably. Writing findings of fact that can withstand scrutiny requires more than summarizing witness statements or cataloguing documentary evidence. It demands a disciplined approach to weighing credibility, applying appropriate standards of proof, acknowledging uncertainty where it exists, and articulating conclusions in language that is precise, defensible, and tied directly to the evidence gathered.

The legal basis for findings of fact in workplace investigations flows from multiple sources across Canadian employment law. Under the Canada Labour Code, which governs federally regulated employers such as banks, telecommunications companies, and interprovincial transportation firms, employers must conduct fair and thorough investigations when complaints arise, and any resulting discipline must be supported by just cause. Provincial employment standards legislation across British Columbia, Alberta, Saskatchewan, Ontario, and Quebec similarly creates frameworks within which employer decisions must be justified. Human rights legislation at both federal and provincial levels requires employers to investigate complaints of discrimination and harassment, with findings that demonstrate the employer took the matter seriously and reached reasonable conclusions. Occupational health and safety statutes across all provinces require investigation of workplace incidents, violence, and harassment, with documented findings that inform corrective action. As of the date of authorship, these legislative frameworks collectively establish that findings of fact are not merely administrative conveniences but legal necessities that form the evidentiary basis for employer action.

Quebec's distinct civil law tradition introduces additional considerations for findings of fact. While common law provinces approach credibility assessment and evidentiary standards through precedent and principles developed over centuries of judicial interpretation, Quebec's Civil Code of Québec establishes a codified framework for contractual obligations between employers and employees. The Quebec Charter of Human Rights and Freedoms, which has quasi-constitutional status, also shapes how employers must approach investigations involving allegations of discrimination or harassment. An investigation report prepared for a Quebec employer must account for these differences, particularly in how conclusions are framed regarding the employment relationship and the employer's contractual obligations. However, the fundamental requirement remains consistent across all Canadian jurisdictions: findings of fact must be supported by evidence, reached through a fair process, and articulated in a manner that demonstrates reasoned analysis rather than arbitrary conclusion.

The standard of proof applicable to workplace investigations differs from criminal proceedings and even from civil litigation, though this distinction is frequently misunderstood by those conducting or reviewing investigations. Criminal cases require proof beyond a reasonable doubt, while civil litigation typically applies the balance of probabilities. Workplace investigations generally apply the civil standard, meaning the investigator must determine whether it is more likely than not that the alleged conduct occurred. However, the application of this standard requires careful attention to the seriousness of the allegations. Where the allegations are particularly grave, such as claims of sexual assault, fraud, or serious criminal conduct, the evidence supporting a finding must be clear, cogent, and compelling. This does not mean that a higher standard of proof applies, but rather that the quality of evidence needed to satisfy the balance of probabilities increases proportionally with the seriousness of the finding. An investigator concluding that an employee committed sexual harassment must marshal evidence of sufficient weight and reliability to support that serious conclusion, whereas a finding that an employee arrived late to work requires correspondingly less evidentiary support.

Credibility assessment lies at the heart of most workplace investigations, and the findings of fact section must demonstrate how the investigator evaluated conflicting accounts. Witnesses rarely provide identical versions of events, and complainants and respondents almost invariably offer divergent narratives. The investigator's task is not to determine who is telling the truth in some absolute sense, but rather to assess whose account is more reliable and consistent with the available evidence. Several factors inform credibility assessment, and findings of fact should reflect consideration of these factors even when they are not explicitly enumerated. Internal consistency matters: does the witness's account hold together logically, or does it contain contradictions that undermine reliability? External consistency is equally important: does the account align with documentary evidence, physical evidence, or the testimony of other witnesses? Motive to fabricate must be considered, though the absence of apparent motive does not guarantee truthfulness, just as the presence of potential motive does not establish dishonesty. Demeanour during the interview may provide some insight, though investigators must be cautious about placing excessive weight on factors such as nervousness or emotional display, which can be influenced by cultural background, personality, or the stress inherent in being interviewed. The timing and circumstances of disclosure can also be relevant, particularly where a complainant delayed reporting and the investigator must assess whether that delay affects credibility or can be explained by understandable reluctance.

Corroboration strengthens findings of fact and provides additional support when conclusions are challenged. Direct corroboration occurs when another witness observed the same events and provides consistent testimony. Indirect corroboration may involve documentary evidence that supports one account over another, such as electronic access records showing that an employee was present at a particular location at a particular time, or email correspondence that reflects contemporaneous statements about the events in question. The investigator must distinguish between true corroboration and mere consistency, as multiple witnesses may provide similar accounts because they discussed the matter beforehand or because their accounts derive from a common source rather than independent observation. Findings of fact should identify what corroboration exists and explain its significance, while also acknowledging where corroboration is lacking and assessing whether the evidence nonetheless supports a conclusion on the balance of probabilities.

The language used to express findings of fact carries significant implications for the defensibility of the investigation report. Conclusions should be stated with appropriate precision, avoiding both overstatement and unnecessary hedging. A finding that an employee engaged in harassment should say precisely that, rather than softening the conclusion with phrases like "may have engaged in conduct that could potentially be characterized as harassment." At the same time, findings should not extend beyond what the evidence supports. If the investigation establishes that an employee made inappropriate comments on three specific occasions, the finding should not suggest a broader pattern unless evidence supports that conclusion. Speculation has no place in findings of fact. Where the evidence is insufficient to reach a conclusion, the appropriate response is to state that the allegation could not be substantiated, not to guess at what might have occurred. The distinction between an unsubstantiated allegation and a false allegation must be clearly understood and reflected in the findings. A conclusion that the complainant's account could not be corroborated is fundamentally different from a conclusion that the complainant fabricated the complaint, and conflating these outcomes creates both legal risk and workplace harm.

Consider a situation that arose at a mid-sized technology company headquartered in Waterloo, Ontario. The company employed approximately two hundred people, including a software development team of forty employees divided among several project groups. In March 2025, a junior developer named Chen submitted a written complaint alleging that her team lead, Marcus, had made repeated unwelcome comments about her appearance, asked her personal questions about her dating life, and on one occasion placed his hand on her lower back while they were standing together reviewing code on a monitor. Chen reported that these incidents occurred over a period of approximately six weeks, between late January and mid-March, and that she initially tried to ignore the behaviour but felt increasingly uncomfortable and distracted at work. She identified two colleagues, Priya and James, as potential witnesses who might have observed some of the conduct.

The company retained an external investigator to conduct a workplace investigation. The investigator interviewed Chen, Marcus, Priya, James, and two additional employees who worked in proximity to Chen and Marcus. Marcus denied making any inappropriate comments, stating that his interactions with Chen were entirely professional and that any comments about her appearance were innocuous compliments of the type he offered to many colleagues. He acknowledged that he may have touched Chen's back on one occasion but characterized it as an inadvertent contact while reaching past her to point at the monitor. Priya reported that she overheard Marcus tell Chen that she "looked really nice today" on at least two occasions and that she observed Chen appear uncomfortable, turning away from Marcus and focusing intently on her computer screen. Priya did not witness the alleged touching incident. James reported that he had not observed anything inappropriate between Marcus and Chen, though he acknowledged that he often wore headphones while working and did not pay close attention to conversations around him. The two additional employees provided similar accounts, noting that they had not observed anything concerning but could not say with certainty what occurred during interactions they did not witness.

The investigator also reviewed electronic records, including calendar entries showing when Marcus and Chen attended meetings together, Slack messages between them discussing work assignments, and building access logs. The documentary evidence confirmed that Marcus and Chen had numerous interactions during the relevant period but did not directly corroborate or contradict either account regarding the specific incidents alleged. The investigator noted that Chen had confided in a friend outside the workplace about the situation in early March, prior to filing her formal complaint, and that friend confirmed Chen described conduct consistent with her formal complaint.

In drafting findings of fact, the investigator needed to address each category of alleged misconduct separately. Regarding the comments about appearance, the investigator found that Marcus made comments about Chen's appearance on multiple occasions. This finding was based on Chen's detailed and consistent account, Priya's partial corroboration regarding at least two such comments, and Marcus's own admission that he offered "compliments" to Chen, even though he characterized them differently than Chen did. The investigator noted that the determination of whether such comments constituted harassment required analysis of whether they were unwelcome and whether, viewed objectively, they created an uncomfortable or hostile work environment. Based on Chen's credible testimony that the comments made her uncomfortable and Priya's observation of Chen's visible discomfort, the investigator concluded that the comments were unwelcome and, in context, contributed to an uncomfortable work environment for Chen.

Regarding the questions about Chen's dating life, the investigator faced a credibility determination with less corroboration. Chen provided a detailed account of specific questions Marcus asked, including when she last had a boyfriend and whether she was "seeing anyone special." Marcus flatly denied asking any such questions. No other witness observed these conversations. The investigator applied the factors relevant to credibility assessment, noting Chen's consistency, the absence of any apparent motive to fabricate, and the specificity of her account. The investigator also noted that Marcus had a motive to deny the conduct given the potential consequences. Weighing these factors, the investigator concluded that, on the balance of probabilities, Marcus did ask Chen personal questions about her dating life as she described. The investigator acknowledged that this finding rested primarily on an assessment of the parties' relative credibility in the absence of corroborating evidence.

The finding regarding physical contact presented additional complexity. Chen alleged that Marcus placed his hand on her lower back, while Marcus admitted to contact but characterized it as inadvertent. The question was not whether contact occurred but rather its nature and intent. The investigator noted that even accepting Marcus's characterization, the contact occurred in circumstances where physical contact was unnecessary and where Chen experienced it as unwelcome. However, the investigator also recognized that a finding of intentional inappropriate touching carried more serious implications than a finding of inadvertent contact that nonetheless made Chen uncomfortable. The investigator concluded that physical contact occurred, that it was unwelcome, but that the evidence was insufficient to determine with confidence whether Marcus's intent was as Chen perceived it or as Marcus described it. The investigator explicitly stated that this finding should not be interpreted as a determination that Chen fabricated or exaggerated this aspect of her complaint, but rather as recognition that the available evidence did not permit a definitive conclusion on the question of intent.

The scenario reveals several critical aspects of writing defensible findings of fact. First, the investigator addressed each allegation separately rather than reaching a global conclusion about whether harassment occurred. This approach allows for nuanced findings that reflect the actual evidence rather than forcing all facts into a single narrative. Second, the investigator explicitly identified the evidence supporting each finding and acknowledged where evidence was lacking or conflicting. This transparency demonstrates that conclusions followed from reasoned analysis rather than assumption or bias. Third, the investigator applied different levels of confidence to different findings based on the available evidence, stating clearly where determinations rested on credibility assessment alone and where corroboration strengthened the conclusion. Fourth, the investigator avoided the trap of treating an inability to reach a definitive finding as equivalent to a finding that the allegation was false.

For HR managers, business owners, and those responsible for workplace investigations, several practical principles emerge from this analysis. Before finalizing findings of fact, review each conclusion and identify the specific evidence supporting it. If a finding cannot be traced to testimony, documents, or other evidence gathered during the investigation, it does not belong in the findings of fact section. Consider whether the evidence would persuade a reasonable third party who has no prior knowledge of the individuals involved or preconceptions about the outcome. Findings of fact must stand on their own evidentiary foundation, not on the investigator's intuition or general impressions.

When assessing credibility, document the factors considered and the weight assigned to each. An investigation report that simply states "the investigator found the complainant more credible than the respondent" without explanation will not withstand scrutiny. Explain why one account was more consistent, better corroborated, or more plausible in light of surrounding circumstances. Where both parties are credible or where credibility factors point in different directions, acknowledge that complexity rather than pretending certainty that does not exist.

Pay careful attention to the language of findings. Use precise formulations that state exactly what the evidence supports. Avoid qualifiers that suggest uncertainty where the evidence is strong, but equally avoid definitive statements where the evidence is equivocal. The difference between "the evidence establishes that" and "the evidence suggests that" and "the evidence does not establish that" represents meaningful distinctions that should be employed deliberately.

Consider how findings will be used in subsequent proceedings. If termination for cause is contemplated, recognize that the findings of fact may be examined by an arbitrator hearing a grievance, a court considering a wrongful dismissal claim, or a human rights tribunal reviewing allegations of discrimination. Write findings as though they will be read by a skeptical adjudicator who has access to the same underlying evidence and will assess whether the conclusions are reasonable. Because in contested cases, that is precisely what will happen.

Finally, remember that findings of fact serve multiple audiences and purposes. They provide the basis for the employer's decision. They communicate to the complainant that the matter was taken seriously and investigated thoroughly. They communicate to the respondent the basis for any adverse conclusions. They create a record that protects the employer against claims that the investigation was inadequate or that discipline was imposed without foundation. They also establish the factual predicate for any corrective measures, whether disciplinary or systemic. Well-crafted findings of fact fulfill all these purposes, while poorly drafted findings create confusion, invite challenge, and undermine the entire investigative process. The time invested in careful, evidence-based, clearly articulated findings of fact is never wasted.
