CPP disability is not a diagnosis benefit. Two people with the same condition can get opposite decisions, because Service Canada is not really asking what you have — it is asking what your condition does to your ability to work, regularly and reliably, at any substantially gainful job.

The two words that decide everything

Severe means your mental or physical disability regularly stops you from doing any type of substantially gainful work. Not your old job — any job you could reasonably do. Prolonged means the disability is long-term and of indefinite duration, or is likely to result in death. Both halves must hold, and you must be under 65 with enough contributions: generally CPP payments in 4 of the last 6 years before you became disabled, or 3 of the last 6 if you have contributed for at least 25 years.

What it pays in 2026

The amount is a flat-rate portion plus 75% of the retirement pension your contributions have earned, which is why it tracks your work history:

Monthly amount
Maximum CPP disability $1,741.20
Average for new beneficiaries (April 2026) ≈ $1,234.68
Post-retirement disability benefit (flat) $610.46
Children’s benefit (per child of a disabled contributor) $307.81

If you are already collecting an early CPP retirement pension and become disabled before 65, the post-retirement disability benefit is the one that applies instead — a flat amount paid on top of your retirement pension.

Applying, and the timeline nobody warns you about

Apply through your My Service Canada Account or by paper form, with a medical report from your doctor or nurse practitioner. Payments begin the fourth month after you are found to meet the test, with up to 11 months of retroactive payments possible — which is a concrete reason not to delay applying. Decisions commonly take around 120 days. Denials can be reconsidered and appealed, and a large share of eventual approvals start as denials, so a first no is not the end of the road.

CPP disability is taxable income. At 65 it switches automatically to a retirement pension — usually a smaller one, which is worth planning around years in advance, not months.
