Psychological Health and Safety (PHS) Due Diligence Checklist: A 2026 Guide for Canadian Employers

The regulatory landscape for workplace safety is shifting rapidly across Canada. For years, the focus was almost exclusively physical; now, it is profoundly psychological. Provincial OHS inspectors are no longer just looking at your fall protection and PPE—they are wanting documented proof that PHS is managed with the same rigour as physical injury.

To protect your organization and your people, you must understand the new standard of Due Diligence for Psychological Health and Safety (PHS).

What is Psychological Health and Safety (PHS) in the Workplace?

Psychological Health and Safety (PHS) is the proactive practice of creating a work environment that protects employees from mental harm while actively promoting well-being. In a legal and regulatory context, PHS focuses on identifying and controlling psychosocial hazards.

Identifying Common Psychosocial Hazards.

• Excessive Workload and Pace: When the mental demand consistently exceeds the worker's capacity to recover.

• Unsupportive Organizational Culture: A lack of psychological safety where employees fear speaking up or seeking help.

• Workplace Bullying and Harassment: Any repetitive, offensive, or degrading behaviour that undermines a worker's dignity.

• Lack of Autonomy: High-demand roles with little to no control over how the work is performed.

• Conflicting Demands: Poor communication or "role ambiguity" that creates chronic mental friction.

These hazards are not just "unpleasant" aspects of work; they are systemic factors that can cause measurable mental injury.

The PHS Compliance Due Diligence Checklist for Canadian Employers

To demonstrate due diligence, an OHS inspector will look for "proof of system." They need to see that you haven't just signed a policy, but have integrated PHS into your daily operations. Use the following breakdown to audit your current evidence.

Psychosocial Safety: Leadership Commitment and PHS Policy Requirements

Leadership and Commitment is the foundation of an effective PHS framework and your primary evidence for a due diligence defence. A formal, documented policy—signed off by the highest level of management—serves two purposes: it legally establishes accountability and it signals genuine commitment.

Audit: Leadership Evidence

Executive proof required for a due diligence defense.

Signed PHS Policy Statement A formal policy, signed by senior management, signaling legal accountability.

Board/Executive Minutes Evidence that PHS is a standing agenda item in high-level leadership reviews.

Resource Allocation Records Documented budget lines specifically for PHS training, audits, and resources.

Examples of PHS Leadership in Action

• The Overload Fix: Instead of just telling an overwhelmed employee to "manage their time," a PHS-informed leader reviews the project scope and reassigns 20% of the tasks to another team member.

• The Culture Shift: A manager starts every weekly meeting by asking, "What is one thing that blocked your progress this week?" and listens without defensiveness.

• The Clarity of Roles: Replacing a vague job description like "Must be a team player" with clear, measurable KPIs so the employee knows exactly what "success" looks like.

• Recruiting with a Psychological Contract: The lens of PHS is applied across the entire employee lifecycle—from the first touchpoint in recruitment to the final exit interview.

• Standardized Policy and Protocols: A mandatory return to work schedule with modified duties to rebuild stamina and confidence without overwhelm. Ensure ongoing check-ins and easy access to resources to adjust the plan for long-term success.

Without visible commitment from the top, PHS initiatives are often perceived as optional, hindering the necessary culture change and resource allocation required to manage hazards effectively.

PHS Planning and Psychosocial Risk Management and Assessment

This documentation proves you are moving past "intent" and into "demonstrable action." It aligns your business with the National Standard of Canada for PHS and proves the lifecycle of hazard management: Find it → Assess it → Control it → Comply.

Audit: Risk Management Proof

Documenting the transition from intent to action.

Hazard Methodology Document Your "Proof of System" for how you identify and evaluate psychosocial hazards.

Psychosocial Hazard Register A living list of discovered risks and the systemic controls implemented.

Legal & Standards Registry Records showing the organization monitors OHS legislation and the National Standard.

You need a documented process for identifying and evaluating psychosocial risks. This "proof of system" shows the inspector exactly how you go about finding hidden mental hazards before they cause injury.

Records of Discovery (Find & Assess It)

Keep detailed records of identified psychosocial hazards and their assessed risk levels. This acts as your "Records of Discovery"—proving you aren't ignoring the specific stressors within your unique workplace.

Examples of Records of Discovery methods are:

• The Psychosocial Audit: Using a standardized tool (like the Guarding Minds at Work survey) to get an objective baseline of your culture.

• Safe-Space Focus Groups: Facilitated sessions (often by a third party) where employees can speak candidly about stressors without fear of reprisal.

• The "Exit Interview" : Analyzing patterns in why people leave—looking specifically for "leadership friction" or "burnout" as the root cause.

Hierarchy of Controls for Psychosocial Risks (Control It)

Outline specific controls used to eliminate or mitigate risks. Following the Hierarchy of Controls—prioritizing systemic changes over individual "resilience" training—is a key marker of a sophisticated safety system.

For example:

• Elimination (The Gold Standard): You identify that "After-Hours Emails" are causing chronic stress, so you implement a server-side "Do Not Disturb" policy from 7 PM to 7 AM.

• Engineering (The System Fix): You notice "Role Conflict" is high, so you create a shared project management dashboard where every task has only one clearly defined owner.

• Administrative (The Policy Fix): Implementing a mandatory "Mental Health Day" policy that doesn't require a doctor’s note.

• Individual (The Support): Offering a meditation app subscription or an EAP. (Important, but only after the other levels are addressed!)

Legal Requirements Register (Comply)

Maintain a list of all applicable PHS-related laws, such as provincial OH&S Acts, WCB requirements, and Human Rights legislation. This proves "Compliance Awareness."

Audit: OH&S Statutory Requirements

Compliance with Federal and Provincial Safety Acts.

Harassment & Violence Regulations (SOR/2020-130) Identification of psychological hazards and prevention policies for federally regulated workplaces.

OHSA Section 25(2)(h): General Duty Clause Evidence of "taking every precaution reasonable" to protect workers from toxic environments and chronic stress.

Provincial Specifics (BC/QC/ON) Alignment with specific mandates like BC’s Policies 115/116 or Quebec’s AOHS regarding psychological harassment.

Audit: WCB / WSIB & Financial Liability

Managing compensable psychological injury risks.

Traumatic & Chronic Stress Coverage Systems to address claims resulting from sudden events or predominant work-related stressors (e.g., bullying).

Presumptive Legislation Compliance Awareness and support protocols for PTSD diagnoses in first responders and frontline roles.

Audit: Human Rights & Privacy Standards

Duty to Accommodate and data protection.

Ground of Disability: Mental Health Documented accommodations for mental health conditions up to the point of undue hardship.

Protected Grounds Harassment Prevention Protection against safety failures rooted in discrimination (race, gender, religion, etc.).

PIPEDA / Privacy Compliance Encryption and restricted access for sensitive somatic and psychological health data.

Audit: Due Diligence & Common Law

Benchmarks for "Reasonable Precautions."

CSA Z1003-13 National Standard Operational use of the Standard as the legal benchmark for PHS due diligence.

Constructive Dismissal Prevention Active management of toxic environments to mitigate common law claims of constructive dismissal.

If you’re following Canadian law, you already have PHS in your system by default. But there’s a massive difference between legal compliance and operational excellence.

True PHS isn't a separate policy folder or a once-a-year training session; it’s a lens. When you operate through that lens, you aren’t just "meeting the standard"—you’re filtering every meeting, every deadline, and every leadership decision through a framework of psychological safety the same way as physical safety.

Implementing PHS Training and Support Systems

While policy and planning show intent, implementation steps prove that the system is actually working on the ground. An auditor is looking for evidence that the PHS process is integrated and effective, not just a document on a shelf. This documentation proves you have taken steps to inform and equip the entire workforce.

Audit: Operational Implementation

Evidence that the system is active on the ground.

Training & Competency Logs Documented attendance for worker PHS basics and leader-specific safety skills.

JHSC Meeting Minutes Proof that the Joint Health and Safety Committee is reviewing mental harm reports.

Incident Investigation Records Documented responses to reports of bullying or work refusals due to mental harm.

Worker-Level Training Records

Document that all workers have received training on PHS basics, how to identify hazards, and—crucially—how to report them without fear of reprisal.

Leader and Supervisor Competency

Canadian legal precedents increasingly focus on supervisor training. You must prove leaders are trained to recognize early mental health concerns and can effectively direct employees to support systems. This complies with the Duty to Inquire and the Duty of Care.

Documented Communication Procedures

Show how PHS is discussed internally. This includes Joint Health and Safety Committee (JHSC) meeting minutes, internal memos, and evidence of "two-way" communication between staff and management.

Psychological Incident Management

You need a clear, documented procedure for investigating psychological incidents, such as reports of bullying or stress-related absences. This proves you treat "mental harm" with the same investigative rigour as a "slip and fall."

This is what a "Psychological Investigation" looks like:

• Non-Adversarial Interviews: Treating a bullying report like a fact-finding mission rather than a "he-said/she-said" argument.

• Root Cause Analysis: Asking, "Did this conflict happen because the person is 'difficult,' or because our lack of role clarity forced them into a territorial battle?"

• Documented Closure: A written report that outlines the steps taken to ensure the behaviour doesn't repeat, which is then filed just like a physical injury report.

• Individual Support Evaluation: Conduct a direct follow-up with the affected employees to assess their perceived level of support during the intervention and evaluate the effectiveness of the resolution.

• Workplace Perception Audit: Implement an anonymous, organization-wide survey to gauge the "psychological safety climate" and gather worker perceptions on the business’s responsiveness to bullying and harassment.

When you treat psychological incidents with the same procedural rigour as physical injuries you signal to your entire team that their mental well-being is an operational priority, not an optional extra. Ultimately, a documented paper trail is what transforms PHS from a vague workplace concept into a defensible, high-performance business asset.

Performance Evaluation and Continuous Improvement

This section provides the objective data to prove the system is effective, sustainable, and continually improving. It confirms that the PHS system is a living management process, fulfilling the safety management cycle of Plan -> Do -> Check -> Act, which is required for effective safety management in Canada.

Audit: Performance Evaluation

Ensuring the system is effective, not just documented.

Internal Audit Reports Documented annual reviews of the PHS system to find gaps before an inspector does.

Worker Feedback Data Aggregated results from pulse surveys or focus groups evaluating the psychosocial climate.

Corrective Action Plans Records showing that when a failure was found, the system was actually updated to prevent recurrence.

Monitoring and Measurement Records (Plan)

Collect data on PHS performance. This includes employee pulse surveys, absenteeism rates linked to psychosocial factors, and turnover data. This data proves the system is being "checked" for effectiveness.

Management Review and Continuous Improvement (Do)

Keep minutes from management review meetings where PHS programs are evaluated. Document any "Corrective Actions" taken when the system falls short of its goals.

Compliance Evaluation and Corrective Actions (Act)

Records of regular self-assessments or internal audits to ensure adherence to standards, along with documented non-conformities and the corrective actions taken.

Paperwork doesn't protect people—systems do. In Canada, "due diligence" means you can prove you actually care about the results of your policies. If you set a policy and never check to see if it's working, you’re wide open to liability. Using a cycle proves that measuring the impact of your actions, and constantly tightening the the system. It’s what transforms "following the law" into "leading a safe workplace."

Roadmapping Psychological Health and Safety: Why Complexity is the Reality

While our compliance checklist provides the necessary documentation to satisfy an inspector, the actual endeavour of creating a psychologically safe workplace—the PHS Roadmap—is far more intricate than a simple tick-box exercise. It is a strategic transformation that involves deeply complex human and organizational factors.

The Sources of PHS Complexity

The difficulty in mapping Psychological Health and Safety stems from its nature as a systemic, intangible, and highly personal risk management challenge.

Physical Safety

Psychological Safety

The Hazard

Objective & Tangible

A broken ladder, a chemical spill, or a missing guardrail.

The Hazard

Subjective & Intangible

Unclear expectations, unsupportive culture, or micro-aggressions.

Visibility

Visible to the Eye

An inspector can walk through a site and "see" the risk immediately.

Visibility

Invisible / Perceptual

The hazard exists in the interaction between the system and the person.

The Intervention

The "Tick-Box" Fix

Replace the ladder. Clean the spill. Install the guardrail. Done.

The Intervention

Strategic Transformation

Developing leaders, shifting culture, and continuous systemic auditing.

Subjective Risk Factors

Unlike physical safety, psychosocial hazards are perceived differently by every employee. What one person views as a challenging opportunity, another views as an overwhelming stressor. PHS accounts for this subjectivity, moving beyond generic wellness programs to address systemic workplace factors.

Data Collection and Measurement

PHS relies heavily on qualitative and self-reported data (surveys, interviews). This data is harder to measure, track, and link directly to a specific intervention than traditional OHS metrics. Furthermore, collecting honest data requires first establishing the very thing you are measuring: psychological safety to speak up.

The Culture and Leadership Hurdle

PHS is, at its core, a cultural shift driven by leadership. It requires managers to demonstrate vulnerability, empathy, and supported accountability—attributes that cannot be implemented overnight or mandated by a policy. The roadmap must include significant, long-term leader development.

The Dynamic System Challenge

A PHS system is not a static document. It must be flexible, iterative, and designed for continuous assessment. As the workplace changes (new technologies, organisational restructuring, economic pressures), new psychosocial risks emerge.
