Trained investigators. Tribunal-tested methodology.
A defensible workplace investigation combines AWI-certified training, OHSA-compliant procedures, and strict independence — so findings hold up when a tribunal, arbitrator, or Ministry inspector reviews the record.
OHSA-compliant methodology. AWI (Association of Workplace Investigators) training. Law-adjacent experience in employment and human rights.
Not your lawyer. Not your HR vendor. We take conflict screening seriously and decline matters where independence is compromised. See the FAQ below for the four scenarios where independence is the whole deliverable.
Every report is drafted to survive tribunal scrutiny. Chain of custody. Contemporaneous notes. Reasons that reference both evidence and law.
Four matter types. One defensible standard.
Ontario employers are most commonly investigated for harassment and discrimination, workplace violence, sexual misconduct, and reprisal or bullying — each governed by OHSA, the Human Rights Code, or both.
Most Ontario workplace investigations fall into one of these patterns. The methodology is the same — the difference is the governing law and what an outside reviewer (an OHSA inspector, the HRTO, an arbitrator) will scrutinize when the report is tested.
Harassment & discrimination
Code-protected ground complaints (sex, race, disability, gender identity, religion), psychological harassment under Bill 132, and patterns across multiple complainants. Most common matter type.
Workplace violence & threats
Bill 168 obligations: threats, physical altercations, intimate-partner violence spillover, and credible-threat assessments. Often parallel to a workplace safety hold.
Sexual harassment & misconduct
Including senior-leader matters, party-cultures, and historical complaints surfaced after a #MeToo moment. Discreet handling, anonymized reporting where the law permits.
Reprisal, bullying & systemic conduct
Allegations of retaliation against complainants, bullying claims that fall outside Code grounds, and pattern-of-conduct investigations across departments or sites.
The law that decides whether the report holds.
Ontario workplace investigations are governed primarily by the Occupational Health and Safety Act (OHSA, including Bill 168 and Bill 132), the Ontario Human Rights Code, and — for federally regulated employers — the Canada Labour Code (Bill C-65).
Ontario Occupational Health and Safety Act obligations to investigate workplace harassment and violence. Includes the statutory duty to investigate "appropriate in the circumstances," now interpreted broadly by the Ministry of Labour and OHSA inspectors.
Code-protected grounds (sex, race, disability, religion, gender identity, family status, and others). Findings often determine whether human rights damages flow at the Human Rights Tribunal of Ontario.
Canada Labour Code harassment and violence provisions for federally regulated employers — banks, telecoms, airlines, interprovincial transport. Different procedural requirements; we maintain federally compliant methodology.
Not every complaint needs us. These four do.
An external investigator is the right call when a senior leader is named, when HR has a conflict, when the matter is headed to tribunal, or when the parties demand it — the FAQ below covers each scenario in detail.
Most workplace complaints can — and should — be handled by a competent in-house HR team. The cases where an independent investigator earns the spend are the ones where independence itself is the deliverable.
When the respondent is a partner, VP, MD, or board member, internal HR cannot credibly investigate someone they functionally report to — the doctrine of reasonable apprehension of bias applies.
If the complainant reports directly to HR, or if HR was a witness to the underlying events, the investigation starts compromised before the first interview.
Once a complaint signals it will move to the HRTO, Ministry of Labour, or court, the investigation becomes evidence. Independent investigations carry significantly more weight on credibility findings.
Complainants and respondents are increasingly counsel-represented and demand external investigation as a condition of participation. Refusing creates its own legal risk.
Same statute. Different evidence map.
We investigate most frequently in healthcare, manufacturing, professional services, education, and technology — and provide specialized support for private members' clubs.
Workplace investigations vary more by industry than most employers realise. The legal framework — Ontario’s Occupational Health and Safety Act, the Human Rights Code, the Employment Standards Act — applies universally. But what gets investigated, and where the evidentiary risks sit, looks very different on a hospital floor than in a financial services office.
Including specialized investigation support for private members' clubs and member-staff complaints.
Patient-facing harassment, allegations against unionized staff with seniority rights, and the intersection of Bill 132 with the Public Hospitals Act. Most complex matter type by document volume — clinical records, scheduling, and shift logs all become relevant evidence.
Bullying, racial harassment, and discrimination in male-dominated environments. Often involves union grievance procedures running in parallel with the investigation, requiring careful coordination so findings are not compromised by grievance disclosure.
Senior-leader matters where the respondent is a partner, MD, or board member. Independence is the entire game here — internal HR cannot credibly investigate someone they functionally report to. Bay Street firms in particular face higher tribunal scrutiny on senior-leader matters.
Faculty-student power-imbalance complaints, allegations involving tenured staff, and matters with media risk. Often run under specific institutional policies (university Senate procedures) on top of statutory obligations.
Founder-to-employee complaints, equity-holder conflicts, and harassment in remote/hybrid workplaces. Evidence-gathering shifts heavily to Slack, email, and platform records — chain of custody on digital evidence is critical and often mishandled by internal teams.
Member-staff complaints, seasonal-worker issues, board-sensitive matters, and harassment or misconduct allegations in golf, yacht, racquet, city, country, and recreation-club environments. Dedicated industry page available.
$9.5K to $15K, fixed-fee. Here is the spread.
Most Ontario workplace investigations cost $9,500–$15,000 on a fixed-fee basis — 40–60% less than law-firm billing rates for the same evidentiary standard. Executive, board, multi-party, or litigation-adjacent matters are quoted above $15,000. The FAQ below breaks down what drives the range.
We quote a fixed fee at the close of intake — not an open hourly meter. AI-assisted case assembly under our Human-Attested standard keeps the fee fixed and the drafting fast; every finding is made, owned, and signed by the named investigator of record.
Simple matters
Single complainant, single respondent, 2–4 witnesses, document volume under 200 pages. Most workplace harassment complaints fit here. Report within 5 business days of the final interview; 2–3 weeks end-to-end.
Standard matters
Multiple complainants or respondents, 5–8 witnesses, document volume 200–800 pages. Includes most discrimination matters and pattern-of-conduct investigations. Turnaround: 3–4 weeks end-to-end.
Complex matters
Senior-leader matters, multi-site or cross-functional investigations, document volume above 800 pages, legal counsel involved on both sides, or active parallel grievance/litigation. Individually quoted. Turnaround: 4–6 weeks.
Four mistakes that compromise the file.
When a workplace complaint is filed, the four most damaging employer mistakes are: letting a conflicted HR team investigate, failing to preserve electronic records immediately, inadequate interim protection for the complainant, and direct communication with the parties.
Most engagements are easier when employers avoid these four pre-investigation missteps. None of them are fatal — but each one adds time, cost, and risk to the matter. We flag them on the intake call regardless of who you eventually retain.
Letting HR investigate when the complainant reports to HR
The most common reason internal investigations are set aside on review. The fix is simple — bring in an external investigator the moment the conflict is visible.
Not preserving documents and electronic records
Slack messages auto-delete, emails get cleared, badge logs roll. The duty to preserve evidence attaches the moment a complaint is received, not when the investigation starts. Issue a litigation hold notice on day one.
Inadequate interim measures
Bill 168 and Bill 132 require employers to protect complainants during the investigation. Doing nothing is a finding against the employer; over-reacting (e.g., suspending the respondent without basis) is also a finding against the employer. Independent advice here is cheap insurance.
Direct communication with complainant or respondent
Once a complaint is filed, every conversation with the parties is potential evidence — and potential reprisal risk. Communications should flow through the investigator or designated counsel, not through the manager involved in the underlying events.
Five steps. No shortcuts.
A workplace investigation in Ontario follows five phases: scoping and conflict check, written plan and party notification, evidence collection, balance-of-probabilities analysis, and a written report with findings and remediation recommendations.
- 01
Intake & scope
Same-day intake call to triage the matter and identify the governing law (OHSA, Bill 168, Bill 132, Bill C-65, or Ontario Human Rights Code). We confirm conflicts, propose methodology, name the investigator of record, and issue a written scope with a fixed fee within 48 hours.
- 02
Plan & notify
Investigation plan signed by the employer before any interview is scheduled. Written notices issued to complainant and respondent with confidentiality and no-reprisal obligations, plain-language explanations of the process, and timelines for response.
- 03
Evidence
Interviews of complainant, respondent, and material witnesses — on the record, recorded where consented, with counsel present where appropriate. Documentary review, chain of custody preserved, and a contemporaneous note of every exchange.
- 04
Analysis
Findings on each allegation against the balance-of-probabilities standard. Credibility assessment grounded in evidence (not impressions), policy and legal framework applied allegation by allegation, and a clear record of what we relied on for each conclusion.
- 05
Report
Written report with findings, rationale, and remediation recommendations. Debrief to the employer (and counsel, when engaged), defensible under tribunal or court scrutiny, and a private record the employer can rely on for the discipline, mediation, or restructuring that follows.

What employers ask before they retain us.
Before retaining a workplace investigator, employers typically ask about Ontario jurisdiction, response time, what makes a report tribunal-defensible, cost, and which laws apply — all answered in full below.
- Do you handle workplace investigations across Ontario?
- Yes. We investigate matters anywhere in Ontario — Toronto, the GTA, Ottawa, Hamilton, Kitchener-Waterloo, and beyond. Most evidence-gathering is hybrid (in-person interviews where it matters, video for logistics) so geography does not extend timelines.
- How quickly can you start an urgent investigation?
- Active complaints get a triage call within one business day and a written scope within 48 hours — including conflict check, proposed methodology, and a named lead investigator. Interviews can begin the following week once the plan is signed.
- What makes an investigation 'tribunal-defensible'?
- Trained investigators (AWI-certified, OHSA-compliant methodology), a documented plan signed by the employer, balance-of-probabilities analysis against each allegation, contemporaneous notes with chain of custody, and a written report that references both evidence and the governing law. 95% of our findings are upheld on legal review.
- Do you work with law firms or directly with employers?
- Both. We are engaged directly by employers, by in-house counsel, and by external employment counsel. We are independent investigators — not your lawyer and not your HR vendor — and we decline matters where independence is compromised.
- What does a workplace investigation cost?
- Most investigations run $9,500–$15,000 fixed-fee depending on complexity, number of parties, and document volume — 40–60% less than Bay Street law-firm rates for the same evidentiary standard. Executive, board, multi-party, or litigation-adjacent matters are quoted above $15,000. We quote a fixed fee on scope-out, not an open hourly meter.
- Which workplace laws do your investigations cover?
- Ontario Occupational Health and Safety Act (Bill 168 / Bill 132), the Ontario Human Rights Code, the Employment Standards Act, and — for federally regulated employers — the Canada Labour Code including Bill C-65 harassment provisions.
- When should an employer hire an external investigator vs. handling it internally?
- When the complaint involves a senior leader, when HR has a real or perceived conflict, when the matter is likely to end up at the Human Rights Tribunal or Ministry of Labour, or when the parties have requested external review. Ontario case law (notably the Toronto v. CUPE Local 79 line) reinforces that both independence and the appearance of independence matter — internal investigations of senior leaders are routinely set aside.
- Can a workplace investigator be sued by the complainant or respondent?
- Independent investigators carry professional liability insurance and rely on the qualified privilege doctrine when acting in good faith and within scope. Most claims against investigators fail on the merits, but the structural protection comes from independence — an in-house investigator who reports to the respondent’s manager is not protected the same way.
- Do I need to notify the Ministry of Labour or HRTO about an internal investigation?
- No. Internal workplace investigations are private. You only become subject to Ministry of Labour or Tribunal involvement if (1) the complainant files externally, (2) you ignore your statutory duty to investigate under OHSA Section 32.0.7, or (3) the matter involves a reportable workplace injury or death.
- What happens after the investigation report is delivered?
- You receive findings on each allegation, recommended remedial actions, and a debrief. From there, you control next steps — discipline (up to and including termination), mediation, policy review, or restructuring. We do not implement; we investigate and document. Most clients extend the engagement with a remediation roadmap — the findings translated into a prioritized, triaged fix plan — scoped separately at the close of the matter, and many re-engage us for follow-up work (training, policy gap audits) once the immediate matter is closed.

AI assists. It never decides.
We use AI to move faster on research, drafting, and pattern-finding. It is a tool in the workflow — not the analyst, not the judgment, and not the author of what we deliver.
A senior human reviews and owns the work.
Every deliverable is reviewed and stood behind by a senior 1205 practitioner. The findings, the recommendations, and the file are human work product — attributable to a named person, not a model.
We escalate when the matter needs it.
Where a question crosses into regulated territory, we say so and route it to employment counsel. We would rather hand off than overreach.
We are clear about our boundaries.
1205 conducts independent investigations and delivers findings — it does not provide legal advice, decide discipline, or implement management decisions.
