5.2 Employment Standards, Labour Relations & Workplace Inquiries

Corporate and workplace investigations represent a substantial and rapidly growing sector of private investigative practice in Ontario. Modern investigators are routinely retained by corporations, human resources departments, labour relations counsel, and municipal entities to investigate allegations of internal fraud, employee absenteeism, labour dispute misconduct, and workplace harassment. Operating effectively in this domain requires deep familiarity with three foundational provincial statutes: the Employment Standards Act, 2000 (ESA), the Labour Relations Act, 1995 (LRA), and the Occupational Health and Safety Act (OHSA). Investigators must conduct inquiries with rigorous procedural fairness, impeccable objectivity, and strict adherence to statutory boundaries.

The Employment Standards Act, 2000 (ESA) Framework

The Employment Standards Act, 2000 (S.O. 2000, c. 41) sets out the minimum statutory rights and responsibilities of employees and employers across Ontario. While the Ministry of Labour, Immigration, Training and Skills Development enforces the ESA, private investigators are frequently retained by employers and legal counsel to verify compliance, investigate policy violations, and gather evidence regarding suspected employment fraud.

Core Statutory Standards Relevant to Investigations

Understanding the baseline rights established by the ESA helps investigators evaluate whether an employee's conduct constitutes legitimate exercise of statutory rights or fraudulent abuse:

• Hours of Work and Overtime (Part VII & VIII): The ESA establishes daily and weekly maximum hours of work (typically 8 hours per day and 48 hours per week unless agreed otherwise in writing) and mandates overtime pay at 1.5 times regular rate after 44 hours per week. Workplace inquiries frequently involve allegations of falsified timesheets, unworked overtime claims, or off-the-clock commercial operations.
• Statutory Leaves of Absence (Part XIV): The ESA provides job-protected leaves, including sick leave, family responsibility leave, bereavement leave, critical illness leave, and declared emergency leaves.
• Termination and Severance of Employment (Part XV): Under Ontario Regulation 288/01 under the ESA, an employee is disentitled to statutory notice of termination or termination pay if they are guilty of "wilful misconduct, disobedience or wilful neglect of duty that is not trivial and has not been condoned by the employer." This is an exacting legal standard requiring clear, compelling evidence.

The Labour Relations Act, 1995 (LRA) & Labour Dispute Inquiries

When collective bargaining breaks down between an employer and a certified trade union, the Labour Relations Act, 1995 (S.O. 1995, c. 1, Sched. A) governs strikes, lockouts, and industrial relations. During a strike or lockout, private security and investigative agencies are frequently engaged to safeguard plant infrastructure, protect non-striking personnel, and document picket line activities.

The Injunction Standard: The Role of the Neutral Investigator

The primary legal purpose of retaining private investigators during an industrial dispute is to gather admissible, objective evidence to support an application for an interlocutory injunction in the Ontario Superior Court of Justice.

Under Canadian labour law, picketing is recognized as a lawful form of freedom of expression. Courts will not enjoin or restrict peaceful picketing merely because it causes economic inconvenience. To obtain an injunction limiting picket line delay times or establishing buffer zones, an employer must prove:

1. Unlawful Misconduct: Pickets are engaging in illegal acts, such as physically blocking entrances, puncturing vehicle tires, smashing windshields, threatening non-striking workers, or engaging in acts of violence;
2. Police Inability to Prevent Immediate Harm: Under Section 102 of Ontario's Courts of Justice Act, the court must be satisfied that reasonable efforts have been made to obtain police assistance and that public policing cannot reasonably control the unlawful acts or prevent irreparable harm;
3. Irreparable Harm: The employer will suffer harm that cannot be adequately compensated by monetary damages.

Evidentiary Protocols for Injunction Affidavits

To satisfy the stringent evidentiary standards required by Superior Court judges, investigators must operate with military precision:

• Chronological Incident Logs: Maintaining detailed, minute-by-minute logs recording the exact date, time, weather conditions, picket captains present, and specific actions observed;
• Continuous Date-Time Stamped Video: Recording continuous video of vehicles attempting to enter or exit plant gates, documenting the exact duration of each stoppage (e.g., stopping delivery trucks for 45 minutes per vehicle);
• Objective, Non-Inflammatory Language: Notes and reports must record factual observations ("Picket #4 placed a wooden board with nails under the front tire of Truck B") rather than emotional or speculative conclusions ("The picketers were wildly out of control");
• Chain of Custody: Digital video files must be immediately backed up, hashed, and stored in secure digital evidence vaults to ensure admissibility during sworn affidavit preparation.

Statutory Prohibitions: Professional Strike-Breaking (LRA Section 78)

Investigators operating in strike environments must be acutely aware of statutory prohibitions under Section 78 of the Labour Relations Act, 1995:

• The prohibition (s. 78(1)): no person, employer, employers' organization or person acting for an employer may engage in strike-related misconduct or retain a professional strike breaker, and no person may act as a professional strike breaker.
• The definitions (s. 78(2)): a professional strike breaker is a person not involved in the dispute whose primary object, in the Board's opinion, is to interfere with, obstruct, prevent, restrain or disrupt the exercise of rights under the Act during or in anticipation of a lawful strike or lock-out. Strike-related misconduct is a course of conduct of incitement, intimidation, coercion, undue influence, provocation, infiltration, surveillance or similar conduct intended to do the same.
• Why this matters for investigators: documenting unlawful acts such as blocked gates or property damage for an injunction application is legitimate. Surveillance, infiltration or provocation aimed at interfering with lawful picketing or union rights is exactly what s. 78 forbids.
• Investigator Conduct: Licensed investigators must never provoke picketers, display physical hostility, engage in verbal shouting matches, infiltrate union picket lines under false pretenses, or perform duties normally performed by striking unionized workers (such as operating plant machinery). Any perception of partisanship or provocation destroys the credibility of the investigator's evidence in court and exposes the agency to severe regulatory and civil liability.

Occupational Health and Safety Act (OHSA) & Workplace Violence / Harassment

A cornerstone of modern Ontario workplace law is the statutory framework governing workplace violence and harassment under the Occupational Health and Safety Act (R.S.O. 1990, c. O.1).

Statutory Evolution: Bill 168 and Bill 132

Ontario's workplace safety legislation underwent two transformative amendments that directly reshaped the private investigation profession:

1. Bill 168 (The Occupational Health and Safety Amendment Act - Workplace Violence and Harassment, 2010):
   • Imposed mandatory duties on all Ontario employers to develop policies, conduct risk assessments, and establish reporting procedures regarding workplace violence and workplace harassment (OHSA Sections 32.0.1 through 32.0.8).
2. Bill 132 (The Sexual Violence and Harassment Action Plan Act, 2016):
   • Explicitly expanded the definition of workplace harassment to include workplace sexual harassment.
   • Enacted Section 32.0.7(1)(a), which created a legally binding statutory duty for employers:

   "An employer shall ensure that an investigation is conducted into incidents and complaints of workplace harassment that is appropriate in the circumstances."

Key Statutory Definitions (OHSA Section 1(1))

Investigators conducting workplace inquiries must evaluate witness testimony against precise statutory definitions:

• Workplace Violence:
  • The exercise of physical force by a person against a worker, in a workplace, that causes or could cause physical injury to the worker;
  • An attempt to exercise physical force against a worker, in a workplace, that could cause physical injury; or
  • A statement or behaviour that it is reasonable for a worker to interpret as a threat to exercise physical force against the worker, in a workplace, that could cause physical injury.
• Workplace Harassment:
  • Engaging in a course of vexatious comment or conduct against a worker in a workplace that is known or ought reasonably to be known to be unwelcome; or
  • Workplace sexual harassment (engaging in vexatious comment/conduct because of sex, sexual orientation, gender identity, or making sexual solicitations/advances where the person making it is in a position to confer, grant, or deny a benefit).

Management Rights Exception: Section 1(4) of OHSA explicitly clarifies that reasonable action taken by an employer or supervisor relating to the management and direction of workers or the workplace (such as performance appraisals, operational directives, and non-abusive disciplinary meetings) does not constitute workplace harassment.

Role and Best Practices of the Independent Workplace Investigator

When a workplace harassment or violence complaint is filed—particularly one involving senior leadership, complex factual disputes, or severe legal exposure—employers frequently retain independent, licensed private investigators to act as external fact-finders.

Foundational Principles: Procedural Fairness and Natural Justice

Workplace investigations are scrutinized closely by labour arbitrators, the Ontario Human Rights Tribunal (HRTO), and civil courts. The investigator must maintain the highest standards of procedural fairness (audi alteram partem — listen to the other side):

1. Freedom From Bias: The investigator must have no personal or professional conflict of interest with any party involved.
2. Notice of Allegations: The respondent must be informed of the specific substance of the allegations against them with sufficient detail to allow them to formulate a full and meaningful response. Ambiguous or "blind" allegations violate procedural fairness.
3. Right to Respond: The respondent must be provided a full, fair opportunity to present their version of events, identify relevant witnesses, and submit documentary evidence.
4. Confidentiality: Information gathered during the inquiry must be kept strictly confidential, shared only with those who need to know for the purpose of the investigation or corrective action.

Five-Stage Interview Protocol

1. Preliminary Scoping & Terms of Reference: Review formal complaint, clarify mandate, identify applicable corporate policies, and verify boundaries of retained authority.
2. Interviewing the Complainant: Detailed chronological interview gathering specifics of each incident (dates, times, locations, exact words, physical conduct, impacts, and potential corroborating witnesses).
3. Witness Interviews & Documentary Review: Interview neutral third-party witnesses identified by the parties. Gather and preserve electronic communications (emails, Slack/Teams logs, text messages) and physical records.
4. Interviewing the Respondent: Present each specific allegation to the respondent. Record their detailed response, examine explanations or alibis, and collect any responsive documentation or witness names.
5. Follow-Up & Final Factual Report: Re-interview parties if material new facts arise. Analyze evidence against the civil standard and author an objective, evidence-based report.

Evidentiary Standard: Balance of Probabilities

In workplace investigations, the standard of proof is the civil standard: the balance of probabilities (i.e., whether it is more likely than not that the alleged incident occurred). The investigator does not apply the criminal standard of "beyond a reasonable doubt."

When assessing contradictory testimony, the investigator must perform a rigorous credibility assessment using established legal factors:

• Internal consistency: Did the witness's story remain coherent and stable throughout the interview?
• External consistency: Is the testimony supported or contradicted by contemporaneous emails, badge swipe logs, or text messages?
• Plausibility: Does the account align with common sense and practical realities?
• Motive to fabricate: Does either party hold an undisclosed interest, personal grievance, or bias?

Structure of the Final Investigation Report

The external investigator produces an objective, comprehensive written report containing:

1. Executive Summary & Mandate: Background and scope of retained authority;
2. Procedural History: Chronology of interviews conducted, evidence reviewed, and confidentiality warnings given;
3. Summary of Evidence: Detailed accounts from complainant, respondent, and witnesses;
4. Credibility Assessments: Transparent rationale explaining why certain testimony was accepted or rejected;
5. Findings of Fact: Concrete, evidence-based determinations on each specific allegation (e.g., "Finding: On May 14, 2026, Respondent did utter the specific comment alleged");
6. Statutory/Policy Assessment: Determining whether the substantiated facts meet the definition of workplace harassment or violence under OHSA and corporate policy.

Crucial Distinction: The investigator acts strictly as a finder of fact. The investigator should not make recommendations regarding employee discipline, termination, or corporate liability, as disciplinary decisions remain the sole prerogative of the employer.
