Critical illness insurance pays a lump sum when you are diagnosed with a specified serious illness. In Canada, where hospital and physician care is publicly funded, the question is whether this coverage is worth the cost. The answer lies in the financial costs that provincial health plans do not cover. This page is part of the guides to life, health and income protection; for a comparison of specific insurers’ policies, see the best critical illness insurance providers.
How it works
- You are diagnosed with a covered condition
- You survive the survival period set in the policy (for example, 30 days for some conditions under RBC Insurance’s plans)
- You file a claim with your insurance company
- You receive a tax-free lump sum and can use it for anything
- The policy usually ends (critical illness insurance usually pays one lump sum)
The benefit is based on the diagnosis alone. You can be diagnosed with cancer, receive the lump sum and be back at work in six months; the claim is still paid in full.
The conditions for a payout, in brief:
- You are diagnosed with a condition the policy covers, meeting the policy's definition of it.
- You survive the survival period after diagnosis, without life support (at RBC Insurance, 30 days for some conditions).
- A cancer diagnosed in the first 90 days after the policy starts isn't covered; at RBC Insurance the policy stays in force but permanently excludes any later cancer claim.
- Standard exclusions apply, such as self-inflicted injury or attempted suicide, misuse of drugs or other intoxicants, and operating a vehicle while impaired.
What critical illness insurance covers
| Category | Conditions |
|---|---|
| Cancer | Life-threatening cancer (most types) |
| Heart | Heart attack, coronary artery bypass, heart valve replacement, aortic surgery |
| Neurological | Stroke, multiple sclerosis, motor neuron disease (including ALS), Parkinson’s, dementia including Alzheimer’s, bacterial meningitis, benign brain tumour |
| Organ failure | Kidney failure, major organ transplant |
| Other | Blindness, deafness, loss of speech, severe burns, paralysis, coma, occupational HIV, aplastic anemia |
The table draws on the covered-condition list of RBC Insurance’s critical illness plan, which covers 26 conditions. Basic policies cover a few conditions, centred on the ones behind most claims: Canada Protection Plan’s no-medical plans, for example, cover heart attack, stroke, three heart surgeries, cancer, aplastic anemia and benign brain tumour.
Read the definitions. Each covered condition has a contractual definition. A “heart attack” has to meet the policy’s medical definition, and a minor cardiac event that doesn’t meet it may not trigger a benefit. The cancer definition is the clause that matters most in most contracts.
Common exclusions
| Exclusion | Notes |
|---|---|
| Pre-existing conditions | Insurers may decline or limit coverage for conditions diagnosed or treated before you apply |
| Cancer waiting period | Some policies exclude a cancer diagnosed in the first 90 days of coverage; at RBC Insurance, such a diagnosis keeps the policy in force but permanently excludes future cancer claims |
| Survival period not met | Death before the survival period ends does not trigger the benefit; that is what life insurance is for |
| Conditions that don’t meet contractual definitions | Minor cardiac events that technically don’t qualify |
| Early-stage cancers | In-situ (non-invasive) and some early-stage cancers are often excluded |
| Misuse of drugs or other intoxicants, or driving while impaired | Standard exclusions |
| Self-inflicted injury or suicide attempt | Standard exclusion |
What the payout covers that provincial health plans do not
Canada’s public health plans cover medically necessary hospital and physician services. A serious illness still brings costs they don’t cover, such as:
- Lost income during treatment and recovery
- Mortgage or rent payments while you can’t work
- Prescription drugs that your provincial or workplace plan doesn’t fully cover
- Medical equipment and home modifications
- Travel for treatment at specialized centres
- Childcare during treatment and recovery
- Private nursing care
- Treatment outside Canada or not covered by your province
What a provincial plan leaves out varies by province; what provincial health insurance covers sets out the gaps.
Who needs critical illness insurance
| Profile | Priority |
|---|---|
| Self-employed, no group benefits or employer sick leave | High |
| Family history of cancer, heart disease or stroke | High |
| Sole income earner with dependants and a mortgage | High |
| Limited savings (less than 6 months of expenses) | High |
| No long-term disability insurance | High |
| Employee with strong group long-term disability coverage | Lower, though it still fills gaps |
| Strong emergency fund (12+ months) or high liquid net worth | Lower |
| Single, no dependants, significant savings | Lower |
| Within about five years of retirement | Lower: shorter coverage window |
Age matters too. Earlier is cheaper, and a 35-year-old pays significantly less than a 45-year-old for the same coverage. By your 60s, substantial savings can make critical illness coverage redundant because you can pay treatment-related costs yourself.
Critical illness vs disability insurance
| Feature | Critical Illness | Disability Insurance |
|---|---|---|
| Trigger | Specific diagnosis | Inability to work |
| Payout | One-time lump sum | Monthly payments |
| Use of funds | Unrestricted | Income replacement |
| Waiting period | Survival period after diagnosis (for example, 30 days for some conditions at RBC Insurance) | Elimination period you choose (for example, 60 or 90 days on RBC’s simplified disability policy) |
| Duration | One-time payment | Until recovery or the end of the benefit period |
| Accidents and non-listed illnesses | Not covered | Covered if you cannot work |
| Covers partial disability | No | Some policies do |
Key distinction: You can be diagnosed with cancer and still be able to work, and critical illness coverage pays anyway. Disability insurance only pays if you cannot work, but it covers accidents and any illness, and it keeps paying through a long recovery. If only one fits the budget, disability coverage is the more versatile of the two. Together, disability covers the lost paycheque and critical illness covers the upfront financial shock. How disability insurance works covers the income side.
Policy types and costs
Term critical illness
- Coverage for a set period, often renewable (RBC Insurance, for example, offers terms of 10, 15 or 20 years, renewable to age 75)
- Lower premiums at the start than coverage to a set age
Level coverage to a set age
- Level premiums to an age such as 75 or 100
- Higher premiums at the start than a 10-year term
Return of premium (ROP)
- An optional rider that refunds premiums in set circumstances, such as keeping the policy without a claim or dying while it is in force
- Adds to the premium
Premiums rise with age and are higher for smokers. Because prices differ by insurer and change over time, get quotes for your own age and health rather than relying on published samples.
How to choose coverage
Coverage amount
One starting point is the larger of:
- 2 years of your after-tax income, or
- Your mortgage balance
Insurers set their own minimums and maximums (PolicyMe, for example, offers $10,000 to $1,000,000).
Number of conditions
- Basic (a few conditions): covers the conditions behind most claims (cancer, heart attack, stroke)
- Comprehensive (many more conditions): also covers rarer conditions
- Quotes for both show what the extra conditions cost for your age and health
Return of premium
One way to judge the ROP feature: if you invested what it adds to the premium instead, would you end up with more money than the ROP refund?
Where to buy
Most critical illness policies are sold through advisors and brokers, for insurers such as Canada Life, iA Financial Group, Manulife, RBC Insurance and Sun Life. PolicyMe sells critical illness coverage online, and Canada Protection Plan sells no-medical critical illness plans. The best critical illness insurance providers covers how the policies differ.
Bottom line
Critical illness insurance fills a gap that neither life insurance nor the public healthcare system covers: the financial impact of being seriously ill but alive. It matters most for breadwinners with families, mortgages and limited savings, and for the self-employed. It sits alongside disability insurance and enough life insurance for your family as part of a complete protection plan.
