How Ontario Disability Insurance Claims Work: From Short Term Disability to LTD Denials and Appeals

March 10, 2026, Kitchener, Ontario

Posted by: Robert Deutschmann, Personal Injury Lawyer

When illness or injury keeps you from working, disability benefits can be your financial lifeline. Understanding how short term disability (STD) and long term disability (LTD) claims work in Ontario can help you protect your income and respond effectively if benefits are denied or cut off.

At Deutschmann de Koning Law, we regularly assist clients with both personal injury and disability matters. Our long term disability claims FAQ  provides a helpful starting point if you are facing an LTD issue.

Short term disability (STD): the first safety net

STD benefits are usually provided through an employer plan and are designed to replace a portion of your income for a limited period. Clear, consistent medical evidence is essential, especially when your disability arises from a car accident or automobile collision.

Long term disability (LTD): when you cannot return quickly

If you remain unable to work after STD ends, you may transition to LTD benefits. Many clients receiving LTD also have serious accident related injuries, including catastrophic injuries, brain injuries, or spinal cord injuries.

Our long term disability claims FAQ explains common policy terms like “own occupation” and “any occupation,” which are central to most LTD disputes.

Common reasons for LTD denial or termination

Denials often cite alleged lack of objective evidence, IME results, or surveillance. These issues frequently arise in brain injury and chronic pain cases, where symptoms may be invisible but still disabling. Working with experienced brain injury lawyers (https://www.ddinjurylaw.com/brain injury lawyers) can help ensure your cognitive and psychological limitations are properly documented.

What to do if your disability claim is denied

If your LTD benefits are denied or cut off, review our long term disability claims FAQ for an overview of typical next steps and timelines, then consider getting tailored legal advice before filing internal appeals.

How a disability lawyer can help

A lawyer can interpret your policy, gather supportive medical evidence, and negotiate or litigate on your behalf. This is especially important when LTD is connected to a serious car accident, catastrophic injury, brain injury, or spinal cord injury.

When disability and personal injury claims overlap

If your disability arises from a collision, you may have a tort claim in addition to LTD. Our car accident lawyers  and automobile accident lawyers coordinate strategies with our disability team to maximize your overall recovery.
