Chronic Pain Injury Claims in Alberta

Last reviewed September 16, 2026. General legal information for Alberta, not legal advice.

How Alberta law treats chronic pain

Since November 1, 2020, the Minor Injury Regulation includes in its definition of a minor injury any clinically associated sequelae of a sprain, strain or whiplash injury, whether physical or psychological, that do not result in a serious impairment. Chronic pain that develops from a soft tissue injury is exactly that kind of sequela.

The practical result: if chronic pain follows a whiplash or back strain, the claim for pain and suffering is capped, unless the pain causes a serious impairment. For chronic pain that follows a fracture, surgery or another injury outside the definition, the cap does not apply at all.

The serious impairment test

The regulation defines a serious impairment as an impairment of a physical or cognitive function that meets all three of these conditions:

1. Substantial inability. It results in a substantial inability to perform the essential tasks of your regular employment, occupation or profession, or of training or education you were enrolled in, despite reasonable efforts to accommodate the impairment and your reasonable efforts to use the accommodation; or a substantial inability to perform the normal activities of your daily living.
2. Ongoing since the accident. The impairment has been continuous from the crash, not something that appeared later with no link.
3. Not expected to improve substantially. The medical prognosis is that it will not get substantially better.

Notice the accommodation language for work and school. A person who could keep working with a modified role, and refused it, will struggle with the first condition. A person who tried modified duties and still could not manage the essential tasks is in a stronger position.

Proving pain nobody can see

Chronic pain rarely shows on imaging. The claim is proven by a consistent, documented history:

• Continuous treatment records from the crash onward: family doctor, physiotherapy, pain clinic and specialists.
• Functional evidence, such as a functional capacity evaluation or occupational therapy assessment, showing what you can and cannot do.
• Work records: attempts to return, modified duties tried, shifts lost and job changes.
• Before-and-after witnesses: coworkers, family, coaches or friends who can describe the change.
• A medical prognosis stating whether substantial improvement is expected.

The single most damaging fact in a chronic pain case is usually an unexplained gap in treatment. If you stopped treatment because Section B ran out or you could not afford it, say so, and keep the proof.

Certified examiners in chronic pain disputes

When the insurer says the injury is minor and you say it is not, either side can require an assessment by a certified examiner once at least 90 days have passed since the crash. The examiner’s written opinion is prima facie evidence on whether the injury is minor. Going into that assessment with complete records and a clear account of your limits is important, because the opinion is hard to displace later.

What is recoverable either way

Even when chronic pain stays inside the cap, these losses are not capped:

• past and future lost income and loss of earning capacity
• future care costs, including pain management and counselling
• housekeeping and home maintenance losses
• documented out-of-pocket expenses

For a person whose chronic pain ends a physical career, these are often the heart of the claim.
