Why Insurance Companies Deny Personal Injury Claims (And How to Fight Back)

If you’ve been injured in a car accident, slip and fall, or another incident in Ontario, you expect your insurance company—or the at-fault party’s insurer—to provide fair compensation. After all, you’ve paid premiums for this protection.

But the harsh reality is that insurance companies often deny, delay, or undervalue personal injury claims to protect their profits. In Ontario, thousands of legitimate claims are challenged every year, leaving victims frustrated and financially strained.

Understanding the most common reasons for personal injury claim denials in Ontario empowers you to protect your rights and build a stronger case. Don’t let an unfair denial stop you from getting the compensation you deserve.

1. Insufficient Evidence or Documentation

Insurance adjusters frequently deny claims by arguing there’s not enough proof linking the accident to your injuries, or that your medical records don’t fully support the extent of your impairment.

Even when your pain is genuine, gaps in documentation give insurers an excuse.

How to Fight Back:

  • Seek immediate medical attention after the accident
  • Follow all recommended treatments consistently
  • Keep detailed records of symptoms, appointments, and expenses
  • Gather photos of the scene, witness statements, and receipts

A skilled personal injury lawyer can obtain independent medical opinions to counter weak evidence claims.

2. Blaming Pre-Existing Conditions

A common tactic is claiming your injuries stem from prior issues like old back problems, degeneration, or previous accidents—rather than the current incident.

The Truth Under Ontario Law: If the accident aggravated or worsened a pre-existing condition, you’re still entitled to compensation for the increased impairment.

3. Alleging You Were Partially at Fault

Insurers may argue you contributed to the accident (e.g., not paying attention, improper footwear in a slip and fall, or violating traffic rules) to reduce or deny your payout.

This is frequent in pedestrian accidents, motorcycle collisions, and multi-vehicle crashes.

Key Fact: Ontario follows contributory negligence rules—even if you’re partially at fault, you can recover damages, adjusted proportionally.

4. Using Delay Tactics

Insurers deliberately stall by:

  • Requesting excessive paperwork
  • Delaying treatment approvals
  • Slowing responses

Their goal is to wear you down until you accept a low settlement or abandon the claim.

An experienced lawyer enforces Ontario’s strict timelines to keep your case moving.

5. Relying on Biased “Independent” Medical Examinations (IMEs)

Insurers often require an IME from doctors they pay, whose reports frequently downplay injuries, claim full recovery, or disconnect symptoms from the accident.

These biased opinions are a primary tool for justifying denials.

6. Claiming You Missed Critical Deadlines

Ontario has non-negotiable limitation periods that insurers exploit:

  • 7 days to notify your own insurer of a motor vehicle accident
  • 30 days to apply for accident benefits
  • 10 days written notice for claims against municipalities (e.g., sidewalk slip and falls)
  • 2 years to commence a lawsuit against the at-fault party

Missing these—even by a day—can permanently bar your claim.

7. Offering Lowball Settlements

When liability is clear, insurers still start with inadequate offers that ignore full entitlements like:

  • Pain and suffering (non-pecuniary damages)
  • Lost wages and future earning potential
  • Medical/rehabilitation expenses
  • Attendant care and housekeeping losses
  • Out-of-pocket costs

Without representation, most victims accept far less than fair value.
