Is critical illness insurance worth it in Canada?

Critical illness insurance is worth it when a serious illness would leave a gap your savings, workplace benefits and government supports cannot cover. Public health care pays for treatment, but not for the income you lose, the take-home drugs some provinces do not fully cover, or the travel and time that come with months of treatment. For someone self-employed, or without strong disability and drug coverage through work, that gap can be large. For someone with solid savings and good group benefits, it may be small enough to cover yourself. Keep in mind that critical illness pays only for the conditions listed in the policy, when the diagnosis meets its definition. How the coverage works is in our critical illness insurance guide, and what it costs is in our guide to critical illness insurance costs.

What a serious illness actually costs

Public health care covers hospital and physician care, but much of the financial impact falls outside it:

• Lifetime cost of cancer. The Canadian Cancer Society’s 2024 report on the economic impact of cancer estimates the average lifetime cost to a person with cancer and their caregivers at about $32,800: roughly $16,000 out of pocket, $11,200 in time spent getting and receiving care, and $5,600 in lost earnings.
• Monthly costs during treatment. In a study of 901 patients at 20 Canadian cancer centres, average out-of-pocket costs over 28 days were about $518, plus $179 for travel and $84 for parking. A third reported a high financial burden, and 29 percent took time off work.
• Take-home cancer drugs. About half of cancer drugs on the market are taken at home, and the Canadian Cancer Society reports that coverage for them is not consistent across provinces. Most private drug coverage comes through employment, so it can be lost if illness ends your job. Provincial programs, such as Ontario’s Trillium Drug Program or Quebec’s public prescription drug insurance plan, may then cover part of the cost after a deductible.
• Lost earnings. On average, earnings were about 10 percent lower in the three years after a cancer diagnosis, a moderate effect overall. Three years after a heart attack, 5 percentage points fewer people were working than among similar people without one; after a stroke, about 20 points fewer. Self-employed cancer patients lost a larger share of earnings than employees.

Averages hide the range. The Canadian Cancer Society notes that for some patients and caregivers, out-of-pocket costs and lost income together can exceed $2,000 a month.

What government supports cover

• EI sickness benefits. Up to 26 weeks at 55 percent of earnings, to a maximum of $729 a week in 2026, after a one week waiting period. You need 600 insured hours and a drop of more than 40 percent in weekly earnings. Self-employed people qualify only if they opted into EI at least 12 months before claiming.
• EI caregiver benefits. Compassionate care benefits run up to 26 weeks for a family member with a significant risk of death within 26 weeks, and the family caregiver benefit up to 15 weeks for a critically ill adult, at the same maximum rate.
• CPP disability. Only if you cannot work regularly at any job over the long term, a strict test. The 2026 maximum is $1,741.20 a month. Quebec residents apply for Quebec Pension Plan disability instead, which has a similar test.
• Job protection. Every province now provides 26 to 27 weeks of unpaid, job-protected leave for serious illness.

These supports replace part of your income for a limited time. None of them pays a lump sum, and they are not meant to cover the out-of-pocket costs above, although some provincial programs help with drug and travel costs.

How it fits with disability insurance

Disability insurance and critical illness insurance solve different problems:

• Disability insurance pays a monthly income mainly while you cannot work, or can only work part of the time, after a waiting period. If you have more than one disability plan, the Financial Consumer Agency of Canada says your combined benefits usually won’t be more than 60 to 85 percent of your regular pay.
• Critical illness insurance pays a lump sum on diagnosis of a covered condition, and the industry’s consumer guide notes that the payment is not related to whether or not you can work.

The Financial Consumer Agency of Canada advises checking your workplace plan before buying extra health or disability insurance, so you don’t pay for coverage you already have. If you have strong group disability coverage, drug coverage and an emergency fund, a serious illness may be manageable without critical illness coverage. If you would lose your income and your drug coverage at the same time, a lump sum can help bridge the gap. Critical illness insurance is not a substitute for disability insurance, though: it pays only for the conditions listed in the policy, when the diagnosis meets the policy’s definition, and many causes of long absences from work, such as back injuries or mental health conditions, are not covered conditions. Our guide to life insurance vs disability insurance covers the disability side.

Who it is most and least worth it for

It tends to be most valuable for:

• The self-employed and small business owners, who usually have no group disability coverage, can get EI sickness benefits only if they opted in at least 12 months earlier, and in Canadian studies lost a larger share of earnings than employees after cancer. Disability insurance is usually their first priority for protecting income; critical illness adds a lump sum on top.
• People whose drug coverage depends on their job, especially in provinces where take-home cancer drugs are not fully covered.
• Households where a partner’s earnings would also fall while they provide care.
• People without an emergency fund to cover several months of reduced income, as long as the premium does not crowd out building one, since savings cover any illness and critical illness covers only the conditions listed.

It tends to be least valuable for people with savings well beyond the three to six months of expenses the Financial Consumer Agency of Canada suggests, plus strong group disability and drug coverage that would continue during an illness.

Is return of premium worth it?

A return of premium rider refunds your premiums if you keep the policy long enough without making a full claim. In one broker’s published example, a 35 year old man with $100,000 of coverage to age 75 added a rider that refunds every premium if he cancels at 65. It raised his monthly premium by about 40 percent. If he paid for 30 years, never claimed and cancelled at 65, the extra premium would have earned the equivalent of about 7 percent a year, assuming the refund is not taxed, and he would have no coverage after 65. That compares well with many low-risk investments, but only if everything goes to plan.

Riders that refund sooner cost more: in the same broker’s examples, a refund after 15 years added 75 to 170 percent, depending on age. A full claim, or cancelling before the refund date, loses most or all of the extra cost, and neither the Canada Revenue Agency nor Revenu Québec has formally ruled on how a refund is taxed. The rider suits people who are confident they will keep the policy to the refund date; prices are in our guide to critical illness insurance costs.

Why claims get denied

We found no published Canadian data on how often critical illness claims are approved. Common reasons for a denial include:

• The diagnosis does not meet the policy’s definition. The OmbudService for Life and Health Insurance describes a case where a brain tumour first classed as benign was found not to meet the cancer definition; after the ombudservice became involved and updated medical information showed the tumour had become aggressive, the insurer reversed its denial.
• The survival period is not met, usually 30 days for heart attack and stroke.
• The 90 day cancer exclusion, when signs, symptoms or a diagnosis of cancer appear soon after the policy starts.
• Non-disclosure discovered within the two year contestability period.

Reading the definitions before you buy, and answering every application question fully, reduces the risk of these.

Frequently asked questions

Is critical illness insurance worth it?

It depends on how well you could absorb months of reduced income and extra costs. It tends to be most valuable for the self-employed and for people without strong workplace disability and drug coverage, and least valuable for people with solid savings and good group benefits.

What does a serious illness cost in Canada if health care is public?

The Canadian Cancer Society estimates the average lifetime cost of cancer to a person with cancer and their caregivers at nearly $33,000, including out-of-pocket costs such as take-home drugs, travel and parking, plus time and lost earnings. Some patients and caregivers face costs and lost income above $2,000 a month.

Do I need critical illness insurance if I have disability insurance?

Not always. Disability insurance replaces part of your income while you cannot work; critical illness pays a lump sum on diagnosis of a covered condition that meets the policy’s definition, whether or not you can work. With strong disability coverage and savings, critical illness matters less; without them, it can fill the gap.

Is return of premium on critical illness insurance worth it?

Only if you keep the policy to the refund date and never make a full claim. In one broker’s published example, a 35 year old who kept the policy 30 years and cancelled at 65 would get the extra premium back at the equivalent of about 7 percent a year, assuming the refund is not taxed. A claim or an early cancellation loses most or all of the extra cost.

Why are critical illness claims denied?

Common reasons include a diagnosis that does not meet the policy’s definition, cancer that appeared within the 90 day exclusion period, and non-disclosure found within the two year contestability period. We found no published Canadian data on claim approval rates.

Does a critical illness claim affect my life insurance?

If your critical illness coverage is a separate policy, a claim does not affect your life insurance: they are separate contracts with separate amounts. If it is a rider on a life policy, it depends on the contract. Some riders pay their own amount and then end, leaving the death benefit unchanged, while in other designs a critical illness payment reduces or ends the life coverage, so ask which kind you have. The diagnosis itself will matter for any future life application, because insurers ask about your medical history.

How much critical illness coverage do I need?

There is no single rule. Canadian insurers’ guides start from the income you would lose and the essential bills you would still have, add one-time recovery costs, and subtract any disability benefits you would receive. Their starting points run from at least six months to a year of income and essential expenses, and some insurers also suggest enough to pay off a specific debt, such as the mortgage.

When is the best age to buy critical illness insurance?

Premiums are based on your age and health when you apply, and on level plans they stay fixed for the life of the policy, so buying younger usually locks in a lower rate. The risk of a critical illness rises with age, older applicants usually need more medical evidence, and most plans stop accepting new applicants at about 65, with some term lengths stopping earlier, as young as the mid-50s. Buying younger also means paying premiums for more years.

Is critical illness insurance worth it if I am single with no dependents?

It can be, because the benefit is normally paid to you while you are alive, not to someone else after your death. Without a partner’s income to fall back on, it can be the money that covers your bills while you recover. Having no dependents, solid savings and strong workplace benefits are also reasons it may matter less, so weigh it against your emergency fund and disability coverage.

Is my advisor recommending critical illness insurance for the commission?

Advisors are usually paid a commission by the insurer, and regulators treat that as a potential conflict of interest. In Ontario, life-licensed agents must disclose in writing the insurers they represent and any conflicts of interest, and guidance from Canada’s insurance regulators expects advisors to put your interests ahead of their own. Ask how your advisor is paid, which insurers they compared, and why the amount and plan suit you.

What to do next

Start with what you already have: workplace disability and drug coverage, savings, and what your household would lose if you could not work for a year. A licensed advisor can then tell you whether critical illness coverage fills a real gap, and how much would fill it.
