When Does the SST Refuse Leave to Appeal a CPP Disability Denial?

What Does It Take to Get Permission to Appeal a CPP Disability Denial?

To get permission to appeal a General Division decision, you need to show an arguable case that the General Division made a specific error, such as a legal or factual error or an unfair process — not just that you disagree with the outcome. That is the test the Social Security Tribunal (SST) Appeal Division applies.

In LD v Minister of Employment and Social Development, 2026 SST 540 (CanLII) (https://www.canlii.org/en/ca/sst/doc/2026/2026sst540/2026sst540.html), the Appeal Division refused permission to appeal a General Division decision that denied a CPP disability pension. The claimant raised five separate factual arguments. None of them cleared the legal bar required to move forward.

What Is the CPP Disability “Qualifying Period” and Why Does It Matter?

The qualifying period — sometimes called the minimum qualifying period or MQP — is the deadline by which your disability must have been both severe and prolonged. If your condition worsened or was only diagnosed after that date, the later evidence may not help your claim.

In this case, the claimant’s coverage ended on December 31, 2019. Medical evidence about iron infusions she began in 2021, or limitations she experienced after that date, could not establish that her disability was severe before the coverage period closed. The tribunal found the evidence did not show functional limitations affecting her ability to work by the end of 2019 — and that conclusion stood on appeal.

What Is a “Factual Error” at the Social Security Tribunal?

A factual error, in SST terms, means the General Division based its decision on a finding it reached by ignoring or misunderstanding relevant evidence. Not every disagreement about facts rises to that level.

The claimant argued the General Division was wrong about when her iron deficiency began, wrong about the role of laxatives versus supplements in her daily routine, and wrong to treat her iron deficiency as resolved. The Appeal Division examined each argument carefully. In each case, the tribunal found the General Division had properly relied on physician reports and the claimant’s own written submissions — it had not ignored or misread the relevant evidence. Pointing to a lab result the claimant interpreted differently from her doctor was not enough to show an arguable error.

Does the Tribunal Interpret Lab Results Itself?

No — the SST does not interpret raw medical data like blood test numbers on its own. The tribunal’s role is to consider what medical professionals conclude from that data: their diagnoses, clinical findings, and opinions.

This is a practical point that matters for how you build your claim. If you believe a lab result supports your case, the strongest approach is to have your treating physician explain in writing what that result means for your functional capacity. A printout showing a ferritin level of 18, without a doctor’s interpretation connecting it to your limitations, may not carry the weight you expect.

What Happens If You Only Challenge the “Prolonged” Part of the Test?

The CPP disability test has two parts: severe and prolonged. If the General Division finds your disability was not severe, it does not need to go on to consider whether it was prolonged — and the Appeal Division will not fault it for skipping that step.

In this case, the claimant argued her IBS was prolonged because she had lived with it since 2004. The Appeal Division noted that prolonged was simply not in play: once the General Division concluded the severity threshold was not met, the prolonged question became irrelevant. Raising evidence about duration alone cannot rescue an appeal where severity was the deciding issue.

How Does a Written Hearing Affect Your CPP Disability Case?

When a claimant chooses a written hearing at the General Division, the entire record consists of documents — there is no oral testimony to clarify ambiguities. Every detail in your submissions and medical reports carries extra weight because there is no opportunity to explain yourself in person.

In this case, the claimant’s own Notice of Appeal described her iron deficiency as “no longer” present, and her written submissions listed both laxatives and supplements together. The General Division relied on exactly what was written. This is one reason why the quality and precision of written submissions at the General Division level is so important — our Ontario CPP disability lawyers regularly help claimants prepare records that accurately reflect their functional limitations before a hearing takes place.

Questions and Records to Discuss with a Lawyer

• What is your minimum qualifying period (MQP) date, and do you have medical evidence that speaks specifically to your functional limitations before that date?
• Have your treating physicians provided written opinions — not just test results — describing how your condition affected your ability to work?
• If you had a written hearing, do your submissions accurately describe your limitations, or could any wording be misread?
• If you received a General Division decision, can you identify a specific error in the tribunal’s reasoning, or are you primarily disagreeing with how it weighed the evidence?
• Are there conditions or treatments that began after your coverage period that you may be relying on to describe your current state?
