The Due Diligence Defence for Ontario Carriers

Why Due Diligence Matters

In Ontario’s commercial transportation industry, “due diligence” isn’t just a buzzword — it’s a legal defence. Under the Highway Traffic Act (HTA), an operator can avoid liability for a contravention if they can demonstrate that they took all reasonable steps to prevent it.

In practice, that means this: when an incident, violation, or audit occurs, you’re judged not only by what happened — but by the systems and culture you had in place before it did.

What the Due Diligence Defence Really Means

The due diligence defence allows a carrier or operator to prove that despite a violation or infraction, they maintained proper oversight and compliance controls. To succeed with this defence, the carrier must be able to demonstrate:

• Established policies and procedures — clear written rules for driver conduct, safety, maintenance, and hours of service.
• Training and supervision — proof that staff were educated, monitored, and corrected when needed.
• Monitoring and documentation — evidence of regular inspections, audits, and corrective actions.
• Continuous improvement — adjustments made when problems were identified.

A due diligence defence is built on documentation and discipline — not excuses or after-the-fact explanations.

How Carriers Lose Their Defence

Many fleets lose their due diligence defence because of gaps — not because they didn’t care. Common failures include:

• Policies that exist but are never updated or enforced.
• Missing training records or driver files.
• Weak monitoring of daily trip inspections, logs, and maintenance.
• Failure to follow up on driver violations or collisions.
• A lack of internal audit or management review.

When a carrier can’t prove that they acted responsibly before a violation occurred, enforcement and tribunals view it as negligence — not bad luck.

Building a Solid Due Diligence Framework

Creating a due diligence defence isn’t complicated, but it does require consistency. Here’s what every Ontario carrier should have in place:

1. Daily Compliance Habits

• Complete and review pre-trip inspections daily.
• Ensure logbooks or ELD records are current and reviewed weekly.
• Track maintenance and defect repairs in real time.

2. Monthly Oversight

• Conduct internal CVOR monitoring and threshold reviews.
• Audit driver hours, logs, and trip inspections.
• Document corrective actions and retraining.

3. Annual Systems Review

• Perform a full facility audit — like an MTO would.
• Update policies and safety manuals.
• Review accident history, training effectiveness, and safety rating.

Proactive Proof is Your Best Defence

When enforcement officers or MTO Facility Auditors arrive, your documentation tells the story. If your files show that you consistently monitored, trained, corrected, and improved, you can demonstrate that you took every reasonable measure to prevent non-compliance.

That’s the essence of the due diligence defence — it transforms your company’s recordkeeping and supervision into legal protection.
