Quick answer
What you need to know first
A CPP Disability lawyer in Mississauga can review your Service Canada denial letter, identify why the “severe and prolonged” test was not met, and explain whether a reconsideration request or Social Security Tribunal appeal is the right next step—and what deadlines apply to your file.
Why Service Canada denies CPP Disability applications
Most denials come down to one problem: the evidence did not satisfy the “severe and prolonged” disability test under the Canada Pension Plan. Service Canada adjudicators look for clear medical documentation that your condition regularly prevents you from doing any substantially gainful work and is expected to last indefinitely or result in death. Common reasons for refusal in Mississauga files include:
- Insufficient specialist reports or objective medical findings
- Gaps in treatment history or inconsistent clinical notes
- Work history that suggests residual capacity or recent earnings
- Failure to show that the disability is “prolonged” as well as “severe”
- Missing or incomplete ISP-1151 (Medical Report) or ISP-2519 (Questionnaire for Disability Benefits)
The 90-day reconsideration: your first appeal step
When Service Canada issues a denial letter, you generally have 90 days to file a request for reconsideration. This is not a new application—it is a formal review of the original decision by a different Service Canada adjudicator. The reconsideration stage is critical because it is your opportunity to fill the evidentiary gaps that led to the denial. UL Lawyers reviews the denial letter line by line, identifies what the adjudicator found missing, and helps you submit a reconsideration package that directly addresses those weaknesses.
- Confirm the exact 90-day deadline from the date of the denial letter
- Review the original application, ISP-1151, and ISP-2519 for errors or omissions
- Gather updated specialist reports, diagnostic imaging, and functional capacity evaluations
- Prepare a written submission that maps your evidence to the “severe and prolonged” test
- Submit the reconsideration request with a complete, organized record
Social Security Tribunal appeals for Mississauga residents
If the reconsideration is also denied, the next step is an appeal to the General Division of the Social Security Tribunal of Canada. The SST appeal has its own deadlines and procedural rules. You will need to file a Notice of Appeal and build a hearing-ready record that may include oral testimony, expert medical evidence, and legal argument about how the CPP-D test applies to your condition. UL Lawyers prepares Mississauga clients for SST appeals by organizing the evidence, drafting written submissions, and representing you at the hearing—whether it is held by videoconference, teleconference, or in person.
- File the Notice of Appeal within the SST deadline
- Assemble a comprehensive hearing record with indexed medical exhibits
- Prepare you for questions about your daily activities, pain, and functional limits
- Present legal argument on the “severe and prolonged” test and relevant case law
- Seek retroactive payments to the date of disability onset where the evidence supports it
Medical evidence that strengthens a CPP-D claim
The difference between a denied claim and an approved one is often the quality and specificity of the medical evidence. Service Canada and the SST need more than a diagnosis—they need a clear picture of how your condition affects your ability to work regularly at any job. UL Lawyers helps Mississauga clients identify and obtain the records that carry weight with adjudicators and tribunal members.
- Specialist consultation reports (rheumatology, neurology, psychiatry, oncology, etc.)
- Functional capacity evaluations and occupational therapy assessments
- Diagnostic imaging, lab results, and objective clinical findings
- Treating physician narratives that address the “severe and prolonged” test directly
- Personal statements and third-party affidavits describing daily limitations
CPP Disability and long-term disability offsets
Many Mississauga residents who apply for CPP Disability also have a long-term disability claim through a group insurance plan or a private policy. CPP-D approval can affect your LTD benefits—and vice versa. Insurers often require you to apply for CPP-D and may reduce your monthly LTD payment by the CPP-D amount. UL Lawyers reviews both files together to identify coordination issues, offset clauses, and repayment obligations before they become surprises.
- Review your LTD policy for CPP-D offset and cooperation clauses
- Calculate the net effect of a CPP-D approval on your monthly LTD benefit
- Address insurer demands to apply for CPP-D or appeal a denial
- Coordinate medical evidence so it supports both the CPP-D and LTD claims
- Identify any retroactive CPP-D lump sum that may trigger an LTD overpayment claim
Retroactive payments and contribution requirements
CPP Disability benefits can be paid retroactively to the date Service Canada determines you became disabled—but there are limits. Generally, retroactive payments cannot go back more than 12 months from the date of application, and you must have made sufficient CPP contributions in the qualifying period. UL Lawyers reviews your earnings record and contribution history to confirm eligibility and maximize the retroactive period where the evidence supports an earlier onset date.
- Confirm your CPP contribution record and qualifying period with Service Canada
- Identify the earliest supportable date of disability onset
- Calculate the maximum retroactive payment available under the legislation
- Advise on the impact of the four-month waiting period on benefit start dates
- Address any gaps in contributions that may affect eligibility
Common mistakes that delay or derail CPP-D claims
Many CPP Disability files in Mississauga are delayed or lost because of avoidable errors. The system is procedural, and missing a step can mean starting over or losing the right to appeal. UL Lawyers helps you avoid the missteps that turn a winnable claim into a closed file.
- Missing the 90-day reconsideration deadline—once it passes, the denial may become final
- Resubmitting the same application and medical evidence without addressing the gaps
- Assuming a doctor’s note saying “disabled” is enough—Service Canada requires functional detail
- Failing to report changes in your condition or work activity during the appeal
- Signing a release or giving a recorded statement to an insurer without legal advice

FAQ
Frequently asked questions
“Severe” means your disability regularly prevents you from doing any substantially gainful work—not just your previous job. “Prolonged” means the disability is expected to be long-continued and of indefinite duration or likely to result in death. Service Canada adjudicators apply both parts of the test strictly, and many denials turn on insufficient evidence for one or both elements.
You generally have 90 days from the date you receive the denial letter to file a request for reconsideration with Service Canada. If you miss the 90-day window, you may be able to request an extension, but it is not guaranteed. A lawyer can confirm your exact deadline and help you submit a complete reconsideration package before time runs out.
If Service Canada denies your reconsideration, you can appeal to the General Division of the Social Security Tribunal of Canada. The SST appeal has its own deadline—typically 90 days from the reconsideration decision. The appeal requires a Notice of Appeal and a hearing-ready record. UL Lawyers can prepare and file the appeal and represent you at the hearing.
Yes, and many LTD policies actually require you to apply for CPP-D. However, your LTD insurer may reduce your monthly benefit by the amount of CPP-D you receive. A lawyer can review your LTD policy, explain the offset, and help coordinate the medical evidence so it supports both claims.
CPP-D benefits can be paid retroactively for up to 12 months from the date Service Canada receives your application. There is also a four-month waiting period before benefits start. The effective date of disability onset is determined by the medical evidence. UL Lawyers reviews your file to identify the earliest supportable onset date and maximize retroactive payments where possible.
Service Canada requires more than a diagnosis. Adjudicators look for specialist reports, diagnostic imaging, clinical notes, functional capacity evaluations, and treating-physician narratives that describe how your condition limits your ability to work regularly. The ISP-1151 Medical Report and ISP-2519 Questionnaire are key forms, but supporting documentation is often what makes the difference.
You are not required to have a lawyer, but the reconsideration and SST appeal processes are legal proceedings with deadlines, evidentiary rules, and procedural requirements. A lawyer can identify why your claim was denied, gather the right evidence, and present your case in a way that addresses the legal test. Many denied claims are approved at reconsideration or appeal with proper representation.
