Canada has three federal disability programmes, and the important thing to understand up front is that they chain together. The Disability Tax Credit is not only a tax matter — approval for it is the gate you have to pass through to get the Canada Disability Benefit, which is cash. So the programme that looks least useful if you owe no income tax is often the one to apply for first.
This page covers the federal programmes only. Provinces and territories run their own supports on top, and for Parkinson’s those are where most of the money actually is — prescription drugs, home care and assistive devices are all provincial. Those have pages of their own: your drug bill depends on your province, home care and long-term care, and walkers, wheelchairs and what Canada will pay for.
Everything below was checked in August 2026. Canada’s figures move on two different clocks: CPP amounts change each January, and the Canada Disability Benefit runs on a benefit year that starts each July. Disability Tax Credit amounts are tied to the tax year.
The fast track most people never hear about
Start here, because it is the single most useful fact on this page.
Service Canada keeps a list of what it calls grave conditions — “a rapidly progressive medical condition… These medical conditions have a high probability of meeting the CPP disability eligibility criteria.” The list has 41 entries, and Parkinson’s disease is one of them.
What that changes is the clock:
| Type of application | Target decision time |
|---|---|
| Standard CPP disability application | 120 calendar days (four months) |
| Confirmed grave condition, including Parkinson’s disease | 30 calendar days |
| Confirmed terminal illness | 5 business days |
Service Canada’s wording: “If we confirm your condition is grave, we aim to process your application within 30 calendar days.”
CPP disability benefit: who qualifies
Four requirements, in Service Canada’s own words:
- Be over 18 and under 65 years old
- Have a mental or physical disability that regularly stops you from doing any type of substantially gainful work
- Have a disability that is long-term and of indefinite duration, or is likely to result in death
- Contributed enough to the CPP
That last one trips people up, because it is not about how ill you are. “Enough contributions” means either:
- “Contributions for at least 4 of the last 6 years prior to the date you became disabled”, or
- “Contributions for at least 25 years, including 3 of the last 6 years”
If you have been out of paid work in Canada for a long stretch, you may fail on contributions alone however severe your symptoms. There are provisions that can help — the child-rearing provision if you had years of low income raising children under 7, credit splitting after a divorce or separation, and credits earned in a country Canada has an agreement with.
“Substantially gainful” has a number attached
For 2026, a substantially gainful occupation is one paying $20,971.45 or more before tax. Service Canada sets out three bands and one obligation:
- Under $7,400 before tax — “this should not affect your disability benefits”
- Between $7,400 and $20,971.45 — “this may demonstrate that you are regularly capable of working and it may affect your disability benefits”
- $20,971.45 or more — “you will likely no longer qualify for disability benefits”
Once you have earned $7,400 in 2026 you must contact Service Canada. They are clear that this “does not necessarily mean that your benefits will stop” — they look at hours worked and how regular the work is — but the call is not optional.
The QPP is not simply the CPP with a different address. The test, the contribution rules, the earnings limit and the decision time are all different, and Retraite Québec does not pay for your medical form. Parkinson’s in Quebec sets out what changes.
What it pays
For 2026:
| Monthly | |
|---|---|
| Basic amount | $610.46 |
| Maximum payment | $1,741.20 |
| Average for new beneficiaries | $1,234.68 |
A note on that last figure: the CPP disability amounts page gives it as the average as of October 2025, while the programme’s overview page labels the same $1,234.68 with a different date. We have used the amounts page’s own date here. The basic and maximum figures are consistent across both pages.
Dependent children can also receive the CPP children’s benefit — under 18, or between 18 and 25 and attending school full-time or part-time. And if you are already drawing a CPP retirement pension and become disabled between 60 and 65, there is a separate post-retirement disability benefit.
How to apply for CPP disability
One cost detail worth knowing before you book the appointment: “Service Canada will pay up to $85 to your healthcare professional for filling out the medical form. If your healthcare professional charges more than $85, you will need to pay the extra amount.”
Disability Tax Credit: apply even if you owe no tax
The DTC is “a non-refundableA credit that can reduce the income tax you owe down to zero, but cannot turn into a refund on its own if you owe nothing.Learn more tax credit that helps people with disabilities, or their supporting family member, reduce the amount of income tax they may have to pay.” On its own, that means it does nothing for you if you owe no tax.
Apply anyway. Two reasons: any unused amount can be transferred to a supporting family member, and — more importantly — DTC approval is a hard requirement for the Canada Disability Benefit, which is cash rather than a tax reduction.
It unlocks more than that. DTC approval is also the key to the Registered Disability Savings Plan and to the Home Accessibility Tax Credit if you are under 65 — see the tax money most people leave behind.
The eligibility test
You may be eligible if a medical practitioner certifies that you have a severe and prolonged impairment in one of the categories, significant limitations in two or more categories, or receive therapy to support a vital function.
The categories are walking, mental functions, dressing, feeding, eliminating, hearing, speaking, vision, and life-sustaining therapy.
For a single category, the test is “marked restriction,” and all three of these must be true:
- You are unable to do the activity, or it takes 3 times longer than someone of similar age without the impairment, even with the use of appropriate therapy, medication, and devices
- This restriction is present all or almost all of the time (generally at least 90%)
- The restriction has lasted or is expected to last for a continuous period of at least 12 months
Note the “3 times longer” wording. For walking, you do not have to be unable to walk. The CRA’s walking criteria are met if you are unable to walk on your own or it takes you three times longer than someone of similar age without the impairment — even with therapy, medication and devices — and that is true at least 90% of the time and has lasted or will last 12 months.
For the cumulative route, the limitations must “exist together all or almost all of the time (generally at least 90%),” and their combined impact must be equivalent to being unable — or taking three times longer — to do an activity in one of the categories.
What it is worth, and how far back
Amounts published by the CRA, by tax year:
| Tax year | Disability amount | Supplement for children under 18 |
|---|---|---|
| 2025 | $10,138 | $5,914 |
| 2024 | $9,872 | $5,758 |
| 2023 | $9,428 | $5,500 |
| 2022 | $8,870 | $5,174 |
| 2021 | $8,662 | $5,053 |
As at August 2026 the CRA has not yet published a figure for the 2026 tax year on this page, so none is shown here. Check the claiming page when you file.
The retroactive window is generous: “If you were eligible for the DTC in past years but did not claim the disability amount, you may be able to claim it going back up to 10 years.” There is a box on the application asking the CRA to adjust your previous returns for you — tick it, or you will have to request the adjustments separately afterwards.
How to apply for the DTC
The digital route has a step that surprises people — you start it, then hand a number to your practitioner.
Who can certify which category matters, because it may save you an appointment:
| Practitioner | Categories they can certify |
|---|---|
| Medical doctor | All impairments |
| Nurse practitioner | All impairments |
| Occupational therapist | Walking, feeding, dressing |
| Physiotherapist | Walking |
| Psychologist | Mental functions |
| Optometrist | Vision |
| Audiologist | Hearing |
| Speech-language pathologist | Speaking |
Unlike the CPP medical form, there is no fee help here: “If your medical practitioner charges a fee for completing the DTC application, you are responsible to pay it.”
A notice on the CRA’s DTC page, current when we checked in August 2026, also warns that you must submit the application either through the digital DTC form or by mail — not through the “submit documents” section of your CRA account. The CRA publishes a processing-time service standard on the application page and updates it monthly; because it moves, we have not reproduced a number here. Applications needing extra information from the practitioner take longer.
Canada Disability Benefit: new, and gated by the DTC
The CDB “provides direct financial support to people with disabilities who are between 18 and 64 years old.” It is recent — the first month of eligibility was June 2025 and payments began in July 2025.
To qualify you must be 18 to 64; have been approved for the Disability Tax Credit; be a Canadian resident for income tax filing purposes; have filed your 2025 federal income tax return (and your spouse or common-law partner theirs, if applicable); and be a Canadian citizen, permanent resident, a person registered or entitled to be registered under the Indian Act, or a protected person.
What it pays:
| Benefit period | Maximum monthly | Based on income from |
|---|---|---|
| July 2026 – June 2027 | $204.20 | your 2025 tax return |
| July 2025 – June 2026 | $200.00 | your 2024 tax return |
Some employment income is ignored in the calculation — Service Canada calls this the working income exemption. For July 2026 to June 2027, up to $10,210 of working income is exempt if you are single, or $14,294 of combined working income if you have a spouse or common-law partner. For the previous period those figures were $10,000 and $14,000.
Above the income threshold the benefit tapers rather than stopping. For the July 2025 to June 2026 period, a single person received the maximum if adjusted family net income after the exemption was $23,000 or less, and the benefit was reduced by 20 cents for every dollar above that. Couples are calculated differently, and the thresholds are restated for each benefit year — check the current figures on the CDB amount page rather than assuming last year’s still apply.
Back payments reach 24 months from when Service Canada receives your application, “but not for any previous months of eligibility prior to June 2025.” That floor is absolute. Your first payment lands on the third Thursday of the month after approval and includes any back payment.
What to do in what order
If you have only just stopped working, there is a step before all of these: EI sickness benefits pay up to 26 weeks while a CPP disability decision is still being made, and applying more than four weeks after your last day of work can cost you benefits.
If this applies to you
| Your situation | What to do |
|---|---|
| You are about to file a CPP disability application | Make sure the diagnosis is stated plainly. Parkinson’s disease is on the grave conditions list — 30 days rather than 120 |
| You owe no income tax, so the DTC looks pointless | Apply anyway. It is the gate for the Canada Disability Benefit, and unused amounts can transfer to a supporting family member |
| You live in Quebec | Apply to the QPP disability pension, not the CPP |
| You have not worked in Canada for many years | You may fail the CPP contribution test regardless of symptoms. Ask about the child-rearing provision, credit splitting, or credits from another country |
| You are working part-time and receiving CPP disability | Contact Service Canada once you reach $7,400 of earnings in 2026. It does not automatically stop your benefit |
| You were eligible years ago but never applied for the DTC | The claim can go back up to 10 years. Tick the box asking the CRA to adjust your previous returns |
| You were approved for the DTC but no CDB payment has arrived | Check that both you and your partner have filed the required federal tax return |
| You are 65 or older | CPP disability is for under-65s. For the CDB, back payments may still be possible up to the month you turned 65 — but never for months before June 2025 |
