Many Canadians assume there’s a strict list of conditions that qualify for the Disability Tax Credit (DTC).
There isn’t.
What matters is how your condition affects your daily life — not just the diagnosis itself.
That said, certain medical conditions are commonly approved when they significantly restrict a person’s ability to function.
What Qualifies for the Disability Tax Credit?
To qualify, your condition must be:
- Severe – It significantly restricts your ability to perform daily activities
- Prolonged – It has lasted (or is expected to last) at least 12 months
- Affect your ability to perform basic activities most or all of the time
These activities include:
- Walking
- Dressing
- Feeding yourself
- Mental functions (memory, focus, problem-solving)
- Speaking or hearing
- Life-sustaining therapy
Common Medical Conditions That May Qualify
Below are examples of conditions that are often approved — if they meet the criteria above.
Mental Health Conditions
- Depression
- Anxiety disorders
- PTSD
- Bipolar disorder
- Severe ADHD
- Cognitive impairments
Chroni Pain and Fatigue
- Fibromyalgia
- Chronic pain syndrome
- Chronic fatigue syndrome
- Long COVID
These conditions may qualify when they significantly limit daily functioning.
Neurological Conditions
- Multiple sclerosis (MS)
- Parkinson’s disease
- Epilepsy
- Traumatic brain injury
Physical and Mobility Impairments
- Severe arthritis
- Spinal cord injuries
- Mobility limitations
- Amputations
Diabetes and Life-Sustaining Therapy
- Insulin-dependent diabetes
- Conditions requiring regular, intensive therapy
To qualify under this category, therapy must meet specific CRA time requirements.
Learning Disabilities and Developmental Conditions
- Dyslexia
- Autism spectrum disorder
- Intellectual disabilities
These may qualify if they significantly impact mental functioning in daily life.
Why Your Condition Might Still Be Denied
Even if you have one of the conditions listed above, your application can still be denied.
That’s because approval depends on:
- How clearly your limitations are described
- Whether your condition meets the CRA’s severity threshold
- The detail provided by your medical practitioner
Get Help Determining If You Qualify
If you’re unsure whether your condition qualifies, it’s worth getting clarity before applying.
You can get help with:
- Assessing whether your condition meets CRA criteria
- Understanding how your limitations should be described
- Avoiding common application mistakes
- Improving your chances of approval
No “Approved List” — It’s About Daily Impact
This is one of the most important things to understand:
- The CRA does not approve or deny applications based on a checklist of conditions.
Instead, it asks:
- How does your condition affect your ability to function?
- How often are you impacted?
- How long have these limitations lasted?
Two people with the same condition may receive different outcomes.
What to Do Next
If you believe your condition may qualify:
- Review the application process carefully
- Ensure your medical practitioner provides detailed information
- Consider getting help before applying
Can You Still Get a Refund?
If you’re approved, you may be eligible for:
- Retroactive refunds (up to 10 years)
- Ongoing tax savings
Key Takeaways
- There is no fixed list of qualifying conditions
- Eligibility depends on functional limitations
- Many physical and mental health conditions may qualify
- Applications are often denied due to lack of detail
- Getting help can improve your chances of approval
