Slip, trip, and fall accidents are among the most common causes of injuries across Canada. Whether they happen in commercial plazas, residential buildings, industrial sites, parking lots, or public walkways, determining who is responsible is often complex. That’s where forensic engineering plays a crucial role.

A forensic engineer uses science, data, and technical evidence to uncover the real cause of an incident—far beyond what the eye can see. Their findings help insurance companies, lawyers, municipalities, building owners, and property managers understand liability, prevent future hazards, and make informed decisions.

Understanding Slip, Trip, and Fall Incidents

Slip, trip, and fall incidents occur when a person loses traction, balance, or stability due to an unsafe condition. Some common causes include:

• Wet or slippery surfaces

• Snow and ice accumulation

• Uneven flooring or pavement

• Poor lighting

• Obstacles or debris

• Worn-out flooring materials

• Design or maintenance defects

While these causes sound simple, determining exactly what happened requires technical expertise and scientific analysis.

Why Forensic Engineering Is Essential in Canada

Canada’s climate alone makes slip-and-fall incidents a major concern. Heavy snowfall, icy walkways, freeze–thaw cycles, and rapid temperature changes create hazardous ground conditions.

But Canadian laws—such as the Occupiers’ Liability Acts—also require property owners to maintain safe conditions for visitors. When an accident occurs, both parties may need unbiased, evidence-based answers.

Forensic engineers provide clarity by:

• Identifying the root cause

• Assessing whether the property was maintained properly

• Evaluating the conditions at the time of the incident

• Determining compliance with building codes and safety standards

• Preparing technical reports for legal claims

This objective and scientific approach helps reduce disputes and supports fair outcomes.

The Forensic Engineering Investigation Process

A slip, trip, and fall investigation typically follows a systematic and highly structured process. Here’s how experts break it down:

1. Scene Examination and Documentation

The first step is a thorough site visit. Engineers document the area using:

• High-resolution photographs and videos

• Measurements of flooring, slope, cracks, defects, or elevations

• Observations of lighting, signage, or warning labels

• Surface conditions such as moisture, ice, spills, or debris

• Weather data, temperature trends, and recent climate events

Engineers often use specialized equipment such as:

• Laser measuring devices

• Moisture meters

• Thermographic cameras

• High-speed cameras for reconstruction

This initial documentation captures crucial evidence before the environment changes.

2. Slip-Resistance Testing

One of the most important tools in forensic investigations is the tribometer—a device that measures the coefficient of friction (COF).

COF helps determine how slippery a floor or surface was at the time of the incident. Engineers compare these readings to standards such as:

• ASTM F2508

• ANSI A326.3

• CSA flooring standards

If the surface falls below acceptable COF thresholds, the engineer can conclude that it was unreasonably slippery.

3. Floor and Surface Condition Assessment

Engineers evaluate:

• Surface materials (tile, concrete, wood, vinyl, asphalt, etc.)

• Wear patterns and deterioration

• Any contamination—like oils, dust, water, or cleaning residue

• Drainage and slope issues

• Frost buildup or melting patterns

These findings help determine whether the hazard was caused by natural conditions, poor design, or inadequate maintenance.

4. Lighting Analysis

Lighting plays a bigger role than most people realize. Poor visibility makes hazards more difficult to detect.

Engineers use lux meters to measure lighting intensity and compare it to:

• Local building codes

• CSA standards

• Property design requirements

If lighting levels fall below minimum values, it could contribute to liability.

5. Weather and Environmental Data Review

In Canada, snow and ice investigations require analyzing:

• Historical weather reports

• Temperature fluctuations

• Snowfall and freezing rain records

• Melting/refreezing cycles

• Maintenance logs for salting, plowing, or sanding

This helps determine whether the property owner took reasonable steps to prevent ice-related hazards.

6. Reviewing Maintenance Records

Engineers request and review:

• Cleaning schedules

• Snow removal logs

• Material replacement records

• Incident reports

• Inspection documentation

If the property owner failed to perform reasonable maintenance, that information becomes critical in determining fault.

7. Human Factors Evaluation

Human behaviour is another key element. Forensic engineers assess:

• Walking speed

• Footwear type

• Visibility

• Distractions

• Reaction time

• Mobility challenges

This helps determine whether the incident occurred solely due to the environment or due to the individual’s actions as well.

8. Code and Standard Compliance Review

Forensic engineers compare findings to:

• Canadian Building Code

• Ontario Building Code / provincial equivalents

• Occupiers’ Liability Acts

• ADA/Accessibility standards (where applicable)

• Manufacturer specifications

Non-compliance can significantly influence liability.

9. Reconstruction of the Incident

When needed, engineers recreate conditions using:

• Computer simulations

• 3D modelling

• Trajectory analysis

• Footstep pattern analysis

These reconstructions are often used in court or insurance disputes to illustrate what happened.

10. Expert Witness Reporting

Finally, forensic engineers prepare:

• Technical reports

• Expert opinions

• Court-ready documentation

• Diagrams and models

• Safety recommendations

Their testimony can be essential in legal settings, offering unbiased evidence based on science and engineering.

Who Needs Slip, Trip, and Fall Forensic Investigations in Canada?

A variety of groups rely on forensic engineering services, including:

• Insurance companies

• Property owners and managers

• Lawyers and law firms

• Municipalities

• Retail stores and malls

• Industrial facilities

• Construction firms

• Condominium boards

Accurate investigations help reduce liability, support fair judgment, and prevent future incidents.

Preventing Slip, Trip, and Fall Incidents: Key Safety Measures

While forensic engineers analyze accidents after they occur, their findings also help prevent future ones. Some preventive measures include:

• Regular snow and ice removal

• Using non-slip mats and coatings

• Improving drainage

• Installing proper lighting

• Ensuring level flooring and prompt repairs

• Clear signage for temporary hazards

• Maintaining detailed inspection logs

These steps significantly reduce risk and legal exposure.

Final Thoughts

Slip, trip, and fall incidents in Canada are common but often misunderstood. Weather, design, materials, maintenance, and human behaviour all play a role. Forensic engineers bring clarity by scientifically examining every detail—helping determine responsibility, improve safety, and support legal and insurance decisions.
