Critical Illness Insurance vs. Life Insurance: Do You Need Both?

Critical illness insurance vs life insurance: What’s the difference?

Critical illness insurance and life insurance are common workplace benefits that help Canadian families maintain financial stability in the face of major life events. 

• Critical illness insurance provides a living benefit to the policyholder in the event of a serious medical diagnosis, illness, or condition. 
• Life insurance provides a death benefit to the policyholder’s chosen beneficiaries in the event of the policyholder’s death. 

Both types of insurance pay out as a one-time lump sum that can be used to cover immediate costs associated with a major illness or death, like funeral expenses, medical costs not covered by health insurance, or lost wages. The key differences between each type of policy are outlined below:

Critical illness insurance: Best for protecting your "right now"

A major medical diagnosis can disrupt your life — and your finances. Critical illness insurance offers a financial safety net to help you get through treatment for a serious condition, such as cancer, heart attack, stroke, or organ failure, without having to worry about bills and other costs. 

How critical illness insurance works

When you’re diagnosed with a serious illness, you’re likely to face new and sudden costs. These could include medical treatment, home care, childcare, replacement services, and more. You may also need to take time off of work. 

Some of your new costs may be covered by public or private health insurance. Others won’t be covered. 

The best critical illness insurance offers a tax-free lump-sum payment that you can use as you choose. For instance, you could use your payout to: 

• Cover healthcare deductible
• Pay for out-of-pocket medical expenses
• Have groceries delivered to your home while you’re off your feet
• Fund transportation to and from your treatment facility
• Modify your house to support new health or mobility challenges

You don’t need to tell your insurance company how you plan to use your payout. If you like, you can use the money to buy video games to occupy your mind during a stressful period. Critical illness policies are about peace of mind to get through a medical crisis with minimal financial fallout.

Who should consider critical illness insurance?

Self-employed workers, parents of young families, those without an emergency fund, and anyone without private health insurance may want to consider getting critical illness insurance. 

Essentially: if you would face serious financial challenges in the event of a major medical diagnosis, critical illness insurance is worth investigating.  

Disability insurance could replace part of your lost income if you need to take a leave of absence or quit your job, but it won’t replace your entire income. An emergency fund may also help soften the financial blow of an unexpected illness but may not provide enough support in the event of a prolonged condition.

As of 2025, 48% of Canadians have no emergency savings. Canadians aged 35–54 are the least likely to have enough emergency savings to last for three months.

Life insurance: Best for protecting your family’s future

Life insurance exists to give your dependents and other loved ones the financial support they would need if you passed away unexpectedly. It’s generally designed to cover a longer period of time than critical illness coverage. 

How life insurance works

Your life insurance policy may cover either your entire lifetime (permanent life insurance) or a specified number of years (term life insurance). If you die during your policy term, the beneficiaries you named in the policy will receive a tax-free lump-sum payout. 

Your loved ones can use the payout from your life insurance policy to cover: 

• Funeral costs
• Outstanding medical bills not covered by insurance 
• Your lost income
• Any outstanding debts you left behind
• Mortgage payments on your home
• Childcare and other expenses that may be created by your absence 
• Funding future financial goals, such as a college fund for your children

‍Term life insurance is the most common type of life insurance, and the most appropriate for the average Canadian family. It’s the most affordable life insurance product and can be set up to expire at a time when you expect your loved ones to no longer be dependent on your income (e.g., retirement).

Who should consider life insurance?

Primary earners, homeowners, and parents are the key market for life insurance. If people in your life depend on your income and would struggle financially if you died, life insurance may be worth considering. 

You may need life insurance even if you don’t have kids. If your spouse or partner depends on your income, or if you provide financial support to other family members, like parents or siblings, life insurance ensures your family has financial protection in the event of your death.

When two people commit to building a life together—whether that means marriage, buying a home, or starting a family—the focus is rightly on hopes and dreams. But true commitment also includes planning for the unexpected. Life insurance is not about being pessimistic; it’s about being responsible, loving, and forward-thinking. You're not planning for death; you're planning for life to keep going for the one you love. – Ivana Govedarica, Licensed Insurance Advisor at PolicyMe

Do I need critical illness insurance and life insurance?

Many Canadians can benefit from both critical illness and life insurance. The type of coverage that will be most beneficial for you and your family will depend on your life circumstances. 

Prioritize critical illness insurance when…

…you’re lacking key workplace benefits. 

A lot of Canadians have access to critical illness, short-term disability, and supplemental health insurance through their workplace. Together, these three group insurance plans can cover a wide range of costs associated with a serious medical diagnosis, including lost wages. 

But if you’re self-employed, a freelancer, or in between jobs, you may not have the financial security of employer benefits. Critical illness insurance is a direct and practical way to make sure you’ll be able to weather a major diagnosis while keeping up with basic living expenses as well as new costs associated with your covered condition. 

Prioritize life insurance when…

…your children are young and/or your mortgage isn’t yet paid off. 

New parents and homeowners have the highest need for life insurance, since their loved ones are most likely to be dependent on their income for basic expenses. But don’t discount life insurance even if you have no children or mortgage. You might also want to consider this coverage if: 

• Other people, like spouses, parents or siblings, depend on your income
• You have significant non-mortgage debt

Consider both when…

…you and your family have limited emergency funds. 

Both critical illness and life insurance benefits exist to provide a financial safety net during a major life crisis. 

If you have a significant amount in your emergency savings fund — say, more than six months of living expenses — you might be comfortable managing the costs of a serious medical condition without an insurance payout. But if the steep and sudden costs that come with illness and death would financially derail you and your family, critical illness and life insurance may be a worthwhile investment.
