Demyan v. Sun Life Assurance Co. of Canada

**What Happened** Michael Demyan worked for Sun Life Assurance Company and had long-term disability insurance through his employer. When he developed cancer and couldn't work due to severe side effects from his treatment, he applied for disability benefits. Sun Life denied his claim, saying he wasn't disabled enough to qualify under the policy terms. **What the Court Decided** The federal court ruled in Demyan's favor, finding that Sun Life's denial was "arbitrary and capricious" - meaning the company's decision was unreasonable and not based on solid evidence. The court looked at medical records showing that Demyan's cancer treatment made him unable to perform his job duties. The judge ordered Sun Life to reverse its denial and approve Demyan's disability benefits. **Why This Matters for Workers** This case shows that insurance companies can't just deny disability claims without good reasons backed by evidence. When workers have legitimate medical conditions that prevent them from working, courts will protect their right to benefits they've paid for through their employment. It demonstrates that employees can successfully challenge unfair denials of disability benefits, especially when they have strong medical documentation supporting their claims.
