Canada Disability Benefit eligibility: who qualifies and how to apply

Who is eligible for the Canada Disability Benefit?

You are eligible for the Canada Disability Benefit if you meet every requirement on Canada.ca's Do you qualify page (checked September 2026). Income decides how much you get, not whether you can apply, so even people who expect a small amount should check these rules.

• Age: 18 to 64. You may apply up to 6 months before your 18th birthday, but processing starts when you turn 18.
• Disability Tax Credit: you must be approved for the DTC.
• Tax return: you, and your spouse or common-law partner if you have one, must have filed a 2025 federal income tax return.
• Residency: you must be a resident of Canada for income tax purposes.
• Status: Canadian citizen, permanent resident, person registered or entitled to be registered under the Indian Act, protected person, or temporary resident who has lived in Canada for the previous 18 months.

One exclusion applies. People serving a sentence of two years or more in a federal penitentiary are not eligible, except for the first and last month of the sentence, and must reapply after release.

Do I need the Disability Tax Credit to get the CDB?

Yes. An approved Disability Tax Credit is a hard requirement; no other disability approval, including CPP disability or a provincial disability program, can replace it. The DTC is approved by the CRA, while the CDB is decided by Service Canada, so you deal with two agencies.

Who qualifies for the Disability Tax Credit?

• Severe and prolonged: a medical practitioner certifies an impairment that has lasted, or is expected to last, for a continuous period of at least 12 months.
• Marked restriction in one category: walking, mental functions, dressing, feeding, eliminating (bowel or bladder), hearing, speaking or vision. You are unable to do the activity, or it takes 3 times longer than for someone of similar age, all or almost all of the time (generally at least 90%).
• Significant limitations in 2 or more categories: limitations that exist together all or almost all of the time and, combined, have the effect of a marked restriction.
• Life-sustaining therapy: therapy to support a vital function, under the CRA's separate rules for time spent on therapy.

If you do not have the DTC yet

1. Get Form T2201, Disability Tax Credit Certificate. Part A is yours; Part B is completed by a medical practitioner.
2. Send it to the CRA through My Account (digital form) or by mail, or have your practitioner submit Part B digitally.
3. Wait for the CRA's notice of determination. If approved, note any end date on the certificate.
4. Then apply for the CDB. You can still receive back months, within the limits on the CDB back pay page.

Practitioners sometimes charge to complete Part B. The one-time $150 CDB supplemental payment exists to offset that cost, and it is paid automatically once you qualify.

Why filing your taxes matters for CDB eligibility

Service Canada uses your tax return to confirm eligibility and calculate the benefit, so a missing return blocks both. For payments from July 2026 to June 2027, the 2025 return is the one that counts.

The requirement is ongoing. Canada.ca says you must still file your return every year to stay eligible, and the benefit depends on keeping an approved DTC, so watch for any end date on your DTC certificate. File even with no income: a $0 return still gives Service Canada the figure it needs. A spouse who refuses or forgets to file can hold up your payments, since both returns feed the CDB amount calculation.

How do I apply for the Canada Disability Benefit?

You can apply for the Canada Disability Benefit in four ways. Canada.ca recommends online for the fastest processing. It also offers an Estimate your benefit amount tool you can try before applying.

What you need before you start

• Your Social Insurance Number and legal status in Canada.
• The 6-digit application code from your invitation letter, if Service Canada mailed you one; otherwise your mailing address.
• Direct deposit details (institution, branch and account numbers). Optional, but it speeds up payment.
• Your net income from your notice of assessment. Optional, but Canada.ca says it helps processing.

Applying for someone else

A legal representative, such as an attorney under a power of attorney, a court-appointed guardian or a trustee, can apply on someone's behalf. Service Canada asks for the applicant's SIN, legal status and mailing address, plus the representative's proof of legal authority, a copy of both sides of an unexpired government-issued ID, and their own mailing address.

Professional representatives working within an organization must also give the organization's mailing address and identification. Expect a longer wait: Canada.ca sets a 49-day decision target when a legal representative applies, compared with 28 days otherwise.

What happens after you apply?

Service Canada mails a decision letter, usually within 28 calendar days. The decision date is printed in the top right corner, and that date starts two clocks: your first payment comes on the third Thursday of the following month, and your 180-day window to challenge the decision begins.

1. If approved: check the monthly amount and the direct deposit details in the letter. Compare the first deposit with the CDB payment dates calendar.
2. If refused or the amount looks wrong: send form CDB0006, request for reconsideration, within 180 days of the letter date, by mail to the Boucherville address or at a Service Canada office. Add any new information, such as a DTC approval notice.
3. If the reconsideration goes against you: appeal to the Social Security Tribunal of Canada, which notifies Service Canada of your appeal.

Once you are receiving the benefit, report changes to address, phone number, bank account, marital status or residency to Service Canada straight away, and update the CRA separately. The Canada Disability Benefit hub links to every other part of the program.
