OH&S Due Diligence in Canada: Why It Matters & How We Help

If you run a business in Canada, you’ve probably heard the term “due diligence” tossed around when talking about occupational health & safety (OH&S). But what does it actually mean—and why should you care more than just ticking a checkbox?

Let’s dive in.

What Is OH&S Due Diligence?

In simple terms, due diligence in OH&S means you took all reasonable steps to keep workers safe. It’s more than paperwork—it’s about your actual efforts:

• Identifying hazards proactively
• Training staff and supervisors to spot and control those hazards
• Documenting everything: inspections, incidents, audits
• Acting on issues—don’t just note them; fix them

WorkSafeBC puts it well: “Due diligence requires taking all reasonable steps to protect workers from harm.” (Open Alberta, bhhcsafetycenter.com, worksafebc.com, ontariohealthandsafety.com)

CCOHS extends that definition, saying employers must have written policies, audit regularly, provide training, empower supervisors, encourage reporting (even near-misses), and document everything (CCOHS).

That’s not bureaucracy—it’s solid risk management, legal protection, and a foundation for safety culture.

1. Prevent Injuries and Incidents

Data doesn’t lie. According to the WHO/ILO, 374 million non-fatal work-related injuries happen annually, costing the global economy around 4% of GDP (worksafebc.com, Wikipedia). In Canada, fatal and serious incidents still occur—many of which are preventable.

Due diligence isn’t about paperwork—it saves lives and prevents pain.

2. Legal Protection Through Compliance

Across provinces, OH&S laws make you responsible for “reasonably practicable” precautions.

In Alberta (OH&S Code Part 2 & 12), BC (Part 4, 8, 11), and federally (Canada Labour Code Part II), due diligence is a legal duty: breach it, and you’re potentially facing fines or criminal charges—as happened under Bill C‑45 (Westray amendments) (bhhcsafetycenter.com, Cassels, Wikipedia, Wikipedia).

Even owners can be held liable unless they can prove they did their due diligence (Cassels).

3. Builds Trust with Team, Clients, and Regulators

When staff see you actively managing hazards, training, and improving—not just posting policies—they feel safer and more engaged.

Clients and whomever they’re dealing with (contractors, insurers, regulators) also notice serious employers who demonstrate care. That’s credibility you can’t fake.

What OH&S Due Diligence Looks Like in Practice

Here’s a quick snapshot of a robust due diligence program:

• Written OH&S policies, procedures, SWPs & JHAs — documented and accessible (worksafebc.com, epe.lac-bac.gc.ca, bhhcsafetycenter.com)
• Hazard assessments & risk control plans — before and during operations
• Training & orientation — for new hires, supervisors, tools, equipment
• Supervisor competency — they understand hazards, enforce rules, and conduct inspections (CCOHS)
• Reported incidents & near-forward processes — investigated, recorded, corrected
• Regular workplace inspections & audits — with documented corrective actions
• Documentation — logs, minutes, training records, inspections (epe.lac-bac.gc.ca)
• Continuous improvement — feedback loops, updates, annual reviews

If you’re nodding—”Yes, but it’s a lot!”—we get it. That’s where Calgary Safety Consultants come in.

Health and Safety Program Development

We help you build or refine your OH&S manual, aligned with Alberta and BC regulations, COR standards, ISO 45001, and industry best practices. That includes policies, SWPs, JHAs, inspection tools, and audit programs. No fluff—just actionable tools.

Hazard Assessments & Worksite Inspections

Whether it’s a warehouse full of door and window units or field installations, we conduct hazard assessments and site inspections, then hand over detailed reports and correction plans that support due diligence.

Supervisor Training

Supervisors do the heavy lifting—literally and figuratively. We provide training so they can identify risks, lead toolbox talks, and maintain compliance—exactly as WorkSafeBC expects (bhhcsafetycenter.com).

Incident & Near-Miss Investigations

Got a close call or accident? We run objective investigations, identify root causes, document findings, and help implement controls to reduce future risk—all essential to due diligence .

Documentation Support

Don’t worry about formatting or storing documents. We create inspection checklists, training logs, incident forms, and maintain version control—so your binder doesn’t just sit there gathering dust.

Ongoing Audits & Reviews

Due diligence is a cycle, not a one-time project. We run annual or semi-annual internal audits and support your continuous improvement process.

Real-World Example: Window & Door Companies

Let’s say company engages Calgary Safety Consultants. Here’s what might unfold:

1. Kickoff & Planning
   We identify your risks—inventory, forklift ops, glazing, working at heights.
2. Policy & Procedure Setup
   Customized OH&S manual, SWPs, JHAs for glass handling, forklift driving, install crews, etc.
3. Training the Crew
   Field workers & office staff get orientation and skill-building on hazards and safe practices.
4. Regular Inspections
   We audit warehouse racks, loading zones, and shop floors monthly with checklists and corrective tracking.
5. Incident Response & Documentation
   Near-miss reporting is encouraged; every documented investigation feeds learning back into policy.
6. Annual Audit & Refinement
   One year later, we re-audit, update manuals, add new SWPs, and retrain as needed.

By the end, not only have you significantly reduced risk—you’ve got a well-documented due diligence framework, legal defensibility, and a safety-first culture.
