CPP Disability: Eligibility, Application & Appealing a Denial

The Legal Test: "Severe and Prolonged"

Under the Canada Pension Plan, a disability qualifies if it is both:

• Severe: The condition prevents you from regularly pursuing "any substantially gainful occupation" — not just your usual job. The test is whether you can work at any job.
• Prolonged: The condition is of indefinite duration or is likely to result in death. A temporary condition (even one lasting years) may not qualify.

Courts and the SST have interpreted "severely disabled" broadly in some decisions — the test is not whether you are 100% unable to work, but whether you can work regularly at a gainful occupation without risking your health.

Contribution Requirements (Minimum Qualifying Period)

You must have contributed to CPP in 4 of the last 6 years (or 3 of the last 6 if you have 25+ years of contributions). This is called the Minimum Qualifying Period (MQP). If your condition began after your MQP ended, you will not qualify — a common trap for applicants who stopped working years before applying.

Application Process

1. Apply online or by mail to Service Canada. Include medical forms completed by your treating physicians.
2. First-level review by Service Canada (approx. 4–6 months). Decision issued by letter.
3. Reconsideration request within 90 days if denied — Service Canada reviews the file again with any new evidence.
4. Appeal to Social Security Tribunal (General Division) within 90 days of reconsideration denial.
5. Appeal to SST Appeal Division if General Division ruling is wrong on a question of law or fact.

Critical Evidence

• Detailed letters from your treating physician and specialists — vague notes are not enough
• Functional capacity evaluations from an occupational therapist
• Psychiatric or psychological assessments (mental health conditions are the #1 basis for approval)
• Employer records, sick leave history, Record of Employment (ROE)
• Pain clinic and physio records

Retroactive Benefits

CPP-D pays retroactively to the later of: (1) when your disability began, or (2) 12 months before the date of your application. The maximum retroactive payment is significant — if you became disabled 3 years ago but only applied now, you would receive up to 12 months of back payments.

CPP-D vs ODSP

CPP-D is a contributory federal benefit — you must have worked and contributed to qualify. ODSP is a provincial needs-tested benefit available to Ontario residents regardless of work history. Most people should apply for both simultaneously. If CPP-D is approved, ODSP deducts the CPP-D amount from the ODSP benefit dollar-for-dollar.
