Add Comment Question: My son was a fire fighter, he got injured at work. He is unable to return to work. He was on medical EI then applied to CPP Disability. They denied his claim due to a response to a question. My son is still awaiting for an MRI then hopefully a knee replacement. His injury is affecting his other knee now, over compensation to his injured knee. Answer: We do handle CPP-Disability (CPPD) appeals. I will contact you directly about this.
