Major depressive disorder, generalized anxiety disorder, PTSD, bipolar disorder, and severe personality disorders are medically recognized disabling conditions. Ontario courts have consistently held that these conditions can qualify as total disabilities under LTD policy definitions. Yet insurer adjudication practices and most group LTD policy structures create unique obstacles not present in physical injury claims.
Many group LTD policies limit payment for disabilities arising from mental or nervous conditions to 24 months over the policy lifetime. After those 24 months, benefits cease regardless of severity — unless the condition is caused by or attributable to an underlying organic brain disorder. This structural limitation affects thousands of legitimate claimants annually.
Human rights challenge: Ontario Human Rights Tribunal decisions and some court rulings have examined whether 24-month mental health caps constitute disability discrimination under the Ontario Human Rights Code, with evolving results. A concurrent human rights complaint alongside a civil LTD lawsuit can be a significant strategic tool. Consult your lawyer about whether this applies to your situation.
Many LTD insurers demand “objective evidence” comparable to imaging studies for physical conditions. No such equivalent exists for psychiatric illness. Ontario courts have held that appropriate objective evidence for mental health claims is the documented clinical assessment, symptom rating scales, longitudinal treatment records, and collateral observations of treating mental health professionals.
The foundation of a successful mental health LTD claim is a robust and consistent treatment relationship with a psychiatrist or psychologist. Standardized assessment tools, detailed clinical notes documenting functional limitations, and an occupational therapist’s functional capacity evidence are all valuable. The treating clinician’s ability to articulate — plainly — why the claimant cannot perform employment duties is often the central element of a successful claim.
