Critical illness (CI) insurance pays a lump-sum benefit if the insured is diagnosed with one of the covered conditions and survives the survival period specified in the policy (commonly 30 days after diagnosis). The benefit is paid unconditionally: the insured can use the money to pay for treatment, to cover lost income, to repay debt, or for any other purpose.
CI insurance originated in South Africa in the 1980s, introduced by the cardiologist Dr. Marius Barnard to address the financial needs of patients who survived serious illness. Canadian products became widely available in the 1990s.
Covered conditions: a basic CI product typically covers three core conditions: life-threatening cancer, heart attack (myocardial infarction meeting specified diagnostic criteria), and stroke. Comprehensive products cover 20 or more conditions, including coronary artery bypass surgery, aortic surgery, kidney failure, major organ transplant, multiple sclerosis, Alzheimer's disease, Parkinson's disease, and others. The policy wording's definition of each condition is critical: a minor or early-stage cancer may not meet the definition of "life-threatening cancer" if the policy definition requires a specified severity.
Survival period: the insured must survive the waiting period (commonly 30 days) after diagnosis to receive the benefit. This filters out terminal diagnoses where the insured does not recover.
Return-of-premium (ROP) option: many CI products offer an optional rider that returns premiums paid if the insured has not made a claim by a specified age (e.g., age 75) or at death. ROP options significantly increase the premium but make CI insurance more acceptable to clients who view it as "wasted" if they never claim.
Needs-analysis role of CI: CI insurance addresses costs and choices that disability insurance does not. A cancer diagnosis may allow the insured to keep working but require expensive treatments, travel to a treatment centre, or time off for recovery. The lump-sum CI benefit can fund those needs without being tied to an income-replacement formula.
