Critical illness insurance with a pre-existing condition

Many people with a health history can still get critical illness insurance, but the outcome depends heavily on the condition and varies more than it does for life insurance. Because the policy pays on diagnosis of conditions like cancer, heart attack and stroke, insurers look closely at anything in your history, or your family’s, that makes those conditions more likely. An application can end in a standard approval, a higher premium, an exclusion for one condition, a postponement or a decline, and when full underwriting says no, some simplified and guaranteed issue products still offer coverage. How the coverage itself works is in our critical illness insurance guide.

How critical illness underwriting differs from life

Life insurance asks how likely you are to die during the policy. Critical illness asks how likely you are to be diagnosed with a covered condition, which many people survive, so a history that barely affects life coverage can matter a great deal for critical illness. Brokers widely report that critical illness underwriting is stricter as a result.

Insurers generally assess the two separately. One major insurer’s underwriting guide tells advisors not to assume life insurability from a critical illness approval. Critical illness is not always stricter, though: at least one insurer’s basic plan covering a few core conditions uses its life insurance underwriting.

What an application can result in

The industry’s consumer guide lists five outcomes:

1. Approved as applied for, at standard rates.
2. Approved at a higher premium for added risk.
3. Approved with an exclusion for a specific condition.
4. Postponed until more time has passed or more information is available.
5. Declined.

An exclusion is often the practical middle ground: coverage for everything else, with one condition carved out. Read the wording closely, because exclusions can reach further than the condition named. One insurer’s contract excludes any covered condition “caused or contributed to by” the excluded risk.

Common health histories

Most insurers do not publish detailed critical illness underwriting manuals, so the tendencies below come from Canadian brokers’ reports and are a guide, not a rule. Every file is assessed individually.

• Cancer history. Fully underwritten coverage is often declined, and this can last for years after treatment; for certain lower-risk histories, some insurers may offer coverage with cancer excluded. How long depends on the cancer, its stage and the insurer.
• Heart attack, stroke or angina. Often a decline for fully underwritten critical illness, since these are core covered conditions.
• Diabetes. Insulin-dependent diabetes commonly leads to a decline, and type 2 diabetes can be harder to place for critical illness than for life insurance.
• Other conditions, such as controlled blood pressure, cholesterol or sleep apnea, are assessed case by case. Ask for a pre-check before applying.

Our hard to insure guides cover how many of these conditions are assessed for life insurance, which is often the better first step.

Family history and genetic testing

Critical illness applications ask about the health of your parents and siblings and the age at which they were diagnosed. Early-onset heart disease, cancer or diabetes in close relatives, and conditions such as motor neuron disease or early Alzheimer’s, can lead to a higher premium or an exclusion for the related condition. One insurer’s advisor guide says there are no simple rules: the relative’s condition, their age at diagnosis, your own age and your overall health all count, and brokers’ examples suggest a diagnosis at a younger age weighs more.

Genetic testing is different. Canada’s Genetic Non-Discrimination Act prohibits anyone, including insurers, from requiring a genetic test or its results as a condition of a contract or its terms, and from collecting or using genetic test results without your written consent. The Supreme Court of Canada upheld the Act in 2020. The Act covers genetic tests, not family history, which insurers still ask about.

Options if full underwriting says no

Several simplified and guaranteed issue products are designed for people with health histories. Their maximums are lower and their rules differ, so compare the terms carefully:

• Products that cover cancer and heart conditions separately. At least one insurer lets a cancer survivor buy coverage for heart attack, stroke and some heart surgeries only, or someone with heart disease or diabetes buy coverage for cancer only. Its applications are accepted or declined without ratings or exclusions, and its underwriting guide says it does not ask about past declines.
• Tiered no-medical products that place you in one of several coverage levels based on a short health questionnaire, including products marketed to people previously denied coverage.
• Guaranteed issue critical illness, which asks no health questions but generally will not pay for a covered condition diagnosed before coverage starts.

These are smaller products, typically capped at $150,000 or less, and they can work as a base layer while your file improves.

Disclose everything

Answer every application question fully, including family history. Under provincial insurance law, if you leave out or misstate an important fact, the insurer can void the policy during the first two years, and contracts typically let it deny a claim in that period too. For fraud, it can do so at any time. After two years, non-disclosure generally no longer voids the contract. Outside Quebec, though, a claim for an illness diagnosed during those first two years can still be contested even if the claim comes later. The two years restart if a lapsed policy is reinstated.

Disclosure also protects you. Outside Quebec, if a policy has a general pre-existing condition clause, the insurer cannot rely on that clause for a condition you disclosed on the application, unless the policy excludes that condition by name.

Which to apply for first

MIB, the industry database underwriters check, records coded medical information from your applications, but not whether you were approved or declined. Many applications ask directly about previous declines, though, so a critical illness decline will likely come up when you apply for life insurance, and you must answer truthfully. If you need both, it often makes sense to start with an anonymous pre-check, then apply for life insurance first, since it is often easier to place. This is about order, not about leaving anything out: answer every question on each application truthfully, including any about other applications. Our guide to life insurance after cancer recommends the same order.

Frequently asked questions

Can I get critical illness insurance with a pre-existing condition?

It depends on the condition. Many applicants with a health history are approved, sometimes at a higher premium or with an exclusion, but outcomes vary more than for life insurance. An application can be approved, approved at a higher premium, approved with an exclusion for a specific condition, postponed, or declined. If full underwriting does not work, some simplified and guaranteed issue products cover people with health histories, with lower maximums and their own limits.

Can I get critical illness insurance after cancer?

Fully underwritten coverage is often declined, and this can last for years after treatment; for certain lower-risk histories, some insurers may offer coverage with cancer excluded. At least one simplified product lets a cancer survivor buy coverage for heart attack, stroke and some heart surgeries only. Products marketed to people previously denied exist too, but they may not cover a cancer you have already had, so check their terms.

Does family history affect critical illness insurance?

Yes. Insurers ask about parents and siblings and the age at which they were diagnosed, and early-onset conditions in close relatives can lead to a higher premium or an exclusion for the related condition. Insurers cannot require a genetic test or use genetic test results without your written consent.

What happens if I do not disclose a condition?

In the first two years, the insurer can void the policy and deny claims if an important fact was left out or misstated, and it can do so for fraud at any time. After two years, non-disclosure generally no longer voids the contract, though outside Quebec a claim for an illness diagnosed in the first two years can still be contested.

Will a critical illness decline affect my life insurance application?

It can come up, because many applications ask about previous declines and MIB may hold coded medical information from your application. Insurers generally underwrite life and critical illness separately, and life is often easier to place, so a critical illness decline does not automatically mean a life decline.

What to do next

With a health history, where you apply matters as much as what you apply for. An anonymous pre-check shows which insurers are likely to offer coverage, and with what exclusions, before you apply.
