Critical illness insurance myths: 10 things people get wrong

Critical illness insurance is easy to misunderstand, and many of the misunderstandings show up only at claim time. Below are ten common ones, each with what is actually true in Canada. How the coverage works from start to finish is in our critical illness insurance guide.

1. “Any cancer diagnosis pays out”

Not every cancer qualifies for the full benefit. The industry benchmark definition, revised in December 2024, excludes several early-stage cancers, including non-melanoma skin cancers that have not spread, thin melanomas that are not ulcerated and have not spread, and early prostate and thyroid cancers. Many insurers pay a partial benefit for some of these instead. The 90 day cancer exclusion after a policy starts can also rule out a claim, and the diagnosis must meet the policy’s definition, usually confirmed by a pathology report.

2. “It’s for paying for chemo”

Hospital-based cancer treatment is publicly funded in Canada. The costs critical illness insurance helps with are mostly elsewhere: lost income, travel and parking, and take-home cancer drugs, which the Canadian Cancer Society reports are not covered consistently across provinces. How you use the benefit is up to you, as the industry’s consumer guide says.

3. “You have to be unable to work to claim”

Your ability to work is not a factor. The benefit is paid on a qualifying diagnosis, whether you stop working or keep going.

4. “It replaces disability insurance”

It does not. Disability insurance pays a monthly income when an illness or injury that meets the policy’s definition of disability keeps you from working, while critical illness pays a lump sum only for listed conditions. In a Canadian Institute of Actuaries study of group long-term disability claims, mental disorders and musculoskeletal conditions made up about half of claims, and neither is a critical illness. Our guide to critical illness vs disability insurance compares them.

5. “Coverage starts the day the policy does”

Several limits apply at the start. Under most policies, if signs, symptoms or a diagnosis of cancer appear in the first 90 days after the policy starts or is reinstated, cancer is excluded permanently. The benchmark definitions apply a one year exclusion to multiple sclerosis and to Parkinson’s disease. For many conditions, such as heart attack and stroke, you must also survive a set period after diagnosis, usually 30 days.

6. “Mortgage critical illness from my bank is the same thing”

It is not. Mortgage critical illness coverage sold by a lender pays the lender, usually up to the outstanding balance, so the benefit shrinks as the mortgage is paid down. The bank certificates we reviewed covered three or four conditions, and one allowed the bank and insurer to change the terms. Lender coverage is quick to get with a short health questionnaire, which can help people who would not qualify for an individual policy, provided they can answer the lender’s health questions accurately, but it is a different product. An individual critical illness policy pays you a set amount, stays the same as your mortgage falls, and stays with you if you change lenders.

7. “Claiming critical illness cancels my life insurance”

Not if they are separate policies: a critical illness claim does not affect a separate life insurance policy. If critical illness is a rider on your life policy, it depends on the design; our guide to life insurance with critical illness explains the difference.

8. “Return of premium makes it free”

A return of premium rider refunds all of your premiums only if you keep the policy for a set period, such as 15 years or to a set age, and no full claim has been paid. Cancel earlier and you get part or none of them back, and a partial payment can reduce the refund. You pay more every month for that promise, sometimes much more, and neither the Canada Revenue Agency nor Revenu Québec has formally ruled on how the refund is taxed. Our guide to whether critical illness insurance is worth it works through an example.

9. “The benefit is taxable”

On a policy you own personally, a critical illness benefit is generally received tax free. There is no specific exemption: the Income Tax Act does not directly address critical illness insurance, and the Canada Revenue Agency has said, in a non-binding view, that the proceeds of a policy paying only critical illness benefits would generally not be included in income. Return of premium refunds are the unsettled exception.

10. “I can deduct the premiums through my corporation”

Generally not. A corporation that owns a critical illness policy cannot deduct the premiums, and premiums a company pays for a policy you own are a taxable benefit to you. Business arrangements deserve an accountant’s review.

Frequently asked questions

Does critical illness insurance pay for any cancer?

No. The full benefit is paid for cancer that meets the policy’s definition. The industry benchmark definition excludes several early-stage cancers, such as most skin cancers and early prostate and thyroid cancers, though many insurers pay a partial benefit for some of them.

Do you have to stop working to claim critical illness insurance?

No. A critical illness benefit is paid on diagnosis of a covered condition that meets the policy’s definition, and your ability to work is not a factor.

Is mortgage critical illness insurance the same as a critical illness policy?

No. Mortgage critical illness coverage from a lender pays your lender, usually up to the outstanding balance, so the benefit shrinks as you pay down the mortgage. An individual critical illness policy pays you a set amount you can use however you need, and it stays with you if you change lenders.

What to do next
