Quick Answer
To apply for the Disability Tax Credit (DTC), you and a qualified medical practitioner complete Form T2201, the Disability Tax Credit Certificate, and submit it to the Canada Revenue Agency (CRA) — most easily online through CRA My Account. The CRA reviews the application, generally within about eight weeks, and issues a Notice of Determination confirming whether you are approved and which years the credit covers. You do not file Form T2201 with your tax return; once approved, the credit is applied to your T1 and can be transferred to a supporting family member if you do not need the full amount. The 2026 Spring Economic Update has proposed a streamlined process for people with certain listed long-lasting conditions, plus an expanded list of practitioners — including podiatrists, physiotherapists, occupational therapists and speech-language pathologists — who could certify eligibility.
Why Applying for the DTC Just Got Simpler
A new diagnosis brings enough to manage without a tax form standing between you and the support you are owed. If you live with a long-term health condition, or you care for someone who does, the Disability Tax Credit is one of the most valuable and most overlooked forms of relief in the Canadian tax system.
Many people start the application, find the medical section intimidating, and quietly give up. Others were turned down years ago and assume nothing has changed since.
Something has changed. In the 2026 Spring Economic Update, the federal government proposed a simpler path for people with certain long-lasting conditions, along with a wider list of health professionals who can sign the form. This guide walks you through who qualifies, who can certify your application, and the exact steps to follow.

What the Disability Tax Credit Is, and What It Can Be Worth
Because the DTC is a non-refundable tax credit, it lowers your tax bill but does not create a refund on its own if you owe no tax. In Ontario, a provincial disability amount is generally added on top of the federal credit, so the combined relief can be meaningful for many households.
The DTC also matters beyond your tax return. Approval is the gateway to open a Registered Disability Savings Plan (RDSP), and it can be a requirement for the Canada Disability Benefit, the child disability benefit, and the disability supplement to the Canada Workers Benefit. Getting approved often unlocks support worth more than the credit itself.
Yet CRA and Statistics Canada figures suggest many Canadians who could qualify never claim the credit. That gap is one of the strongest reasons to apply.
Who Can Certify Your DTC Application Now
The 2026 Spring Economic Update proposes to widen this list further. Under the proposal, podiatrists could certify walking impairments, while physiotherapists, occupational therapists and speech-language pathologists could certify a broader range of impairments within their training and practice. Public guardians and trustees could also certify for certain adults in their care.
This expanded list is proposed to apply to certificates issued after 2026, for the 2027 and later tax years. It is meant to help people who see a therapist regularly but lack easy access to a family doctor.
One point is important: the rules for who qualifies are not changing. The eligibility standard remains a severe and prolonged impairment that markedly restricts a basic activity of daily living, or that meets the cumulative-effect rule. Only the process and the list of certifiers are proposed to change.
| Practitioner | Impairments they may certify | Status |
|---|---|---|
| Physician or nurse practitioner | All impairment categories | In effect |
| Optometrist | Vision (seeing) | In effect |
| Audiologist | Hearing | In effect |
| Psychologist | Mental functions | In effect |
| Physiotherapist | Walking; proposed to add feeding, dressing and related cumulative effects | Proposed 2026 |
| Occupational therapist | Walking, feeding, dressing; proposed to add eliminating and related cumulative effects | Proposed 2026 |
| Speech-language pathologist | Speaking; proposed to add feeding, hearing and related cumulative effects | Proposed 2026 |
| Podiatrist | Walking | Proposed 2026 |
Your Step-by-Step DTC Application Roadmap
- 1Gather your detailsCollect your diagnosis and notes on how your condition affects daily life, so the medical section can be specific.
- 2Start Part A onlineOpen Form T2201 in your CRA My Account. The system pre-fills your information and gives you a reference number.
- 3Hand off to your practitionerGive the reference number to your medical practitioner, who completes Part B describing how your impairment restricts daily activities.
- 4Submit the formSubmit online through My Account, or mail the completed form to your CRA tax centre. You do not attach it to your tax return.
- 5Wait for the reviewThe CRA review generally takes about eight weeks, though complex cases can take longer.
- 6Read your Notice of DeterminationThis letter confirms whether you are approved and which years the credit covers.
- 7Claim and look backClaim the credit when you file your T1 return, and ask the CRA to adjust prior years if you qualified in the past.
Standard Path vs Streamlined Path: What Is Different
The listed conditions in the proposal include diagnoses such as Alzheimer disease, advanced or severe Parkinson disease, cystic fibrosis, schizophrenia, and severe autism spectrum disorder. For these conditions, the medical section would be shorter because the diagnosis itself signals a lasting, marked impairment.
Two things stay the same. The eligibility criteria do not change, and the CRA keeps the authority to ask for more information. The streamlined route is proposed for the 2026 and later tax years, while the standard route continues for anyone whose condition is not on the list.
| Feature | Standard path | Streamlined path (proposed) |
|---|---|---|
| Who it applies to | Anyone with a qualifying impairment | People formally diagnosed with a listed long-lasting condition |
| What the practitioner certifies | How the impairment restricts each basic activity of daily living | The existence of the listed condition |
| Form detail required | Full Part B descriptions | Reduced certification |
| Eligibility criteria | Severe and prolonged impairment | Severe and prolonged impairment (unchanged) |
| CRA can request more information | Yes | Yes |
| Proposed to apply | Current process | 2026 and later tax years |
Common Mistakes That Delay or Sink a DTC Claim
Most rejected or delayed applications come down to a handful of avoidable errors. Watch for these:
- →Vague impairment descriptions that do not explain how the condition markedly restricts a daily activity most of the time.
- →Missing signatures, since the form is incomplete without both your signature and the practitioner signature, and the CRA will not process it.
- →Choosing a certifier who does not know your condition well, or who is outside the impairment they are permitted to certify.
- →Attaching Form T2201 to your tax return, when the certificate is meant to be submitted separately.
- →Forgetting to ask the CRA to adjust prior years, which can mean missing a potentially large retroactive amount.
- →Overlooking the transfer to a supporting family member when the applicant income is too low to use the credit.
- →Assuming the streamlined path applies to everyone, when it is proposed only for certain listed conditions.
What Happens After You Submit Form T2201
Sometimes the CRA needs more detail before deciding. If the CRA asks for more information, your practitioner can usually clarify how your impairment affects daily living, and the application continues from there.
If your application is denied, you have options. You can ask the CRA to review the decision with added medical detail, or file a formal objection within the time limit shown on your notice. A denial is not always the end of the road, and many are overturned with stronger supporting information.

Get Your DTC Application Right the First Time
The Disability Tax Credit can be worth far more than a line on your tax return, because approval often unlocks the RDSP, the Canada Disability Benefit, and refunds for past years. The 2026 changes are proposed to make the process simpler, though the eligibility rules stay the same.
