Ontario legal information · Ottawa and Eastern Ontario

01 · Understanding the issue

What the page should help you decide

The Negligence Act permits damages to be reduced according to the claimant's share of fault.2

Iannarella illustrates why testimony, physical evidence and a disciplined review of the driving sequence matter.

02 · Insurance and responsibility

Keep the legal question, insurance route and next practical step distinct.

Legal question

The civil claim assigns responsibility under negligence law.

Coverage or process

First-party accident benefits may remain available regardless of fault, subject to the SABS.

Practical step

A negotiated percentage should be tied to evidence, not simply to the police charge or insurer label.

03 · Evidence

Build the answer from records another person can check.

01Event and responsibility

Lane positions, signals, speed, sightlines and right-of-way.

02Health and causation

Injury onset and the mechanics of impact.

03Function and loss

Work and activity losses after the collision.

04Documents and decisions

Photos, vehicle data, witnesses, reports and prior statements.

Small details in the driving sequence can change how responsibility is divided.
04 · Timing and decisions

Protect the next real date.

Scene video and vehicle data may disappear quickly.3

Protect insurer-notice, benefit and lawsuit dates even while fault remains contested.

05 · When legal help may matter

How a personal injury lawyer may use this information.

General information explains the framework. Legal advice should connect that framework to the event, the people and insurers involved, the available records and the deadlines in the individual claim.

  • Reconstruct both drivers' actions
  • Test independent evidence
  • Apply the Negligence Act
  • Model the percentage effect

Not every file requires every step or legal representation. The work should respond to the actual dispute, evidence gap or decision that is approaching.
