What are the benefits of critical illness insurance?

Lump sum payout

CII provides a lump sum payout if you are diagnosed with a covered critical illness. This allows you to focus on treatment and recovery without worrying about additional medical or other costs.

Payout flexibility

The lump sum from CII is yours to use however you see fit - to pay medical bills, daily living expenses, mortgage, treatment/recovery, home health care, etc.

Complementary to health insurance

CII works alongside other types of coverage, like Personal Health Insurance (PHI) to cover additional expenses not paid for by regular medical plans. It helps fill the gaps if a critical illness strikes.  

How does critical illness insurance work?

CII pays a lump-sum payment that you can use however you want; to help you, your family or business financially manage a life changing illness so that you can focus on your recovery.

Use the funds for medical expenses, lost income, home care, mortgage payments, or any other needs during your recovery. 

What does critical illness insurance cover?   

Illnesses commonly covered by CII include cancer, heart attack, stroke, major organ failure (on waiting list), severe burns, and more.

Coverage varies by product:

  • Sun Critical Illness Insurance covers 26 full-payout illnesses, 8 partial-payout illnesses, and 5 full-payout childhood illnesses
  • Express Critical Illness Insurance covers 1, 3, or 7 illnesses depending on your chosen plan (basic, enhanced, or comfort)

Claims are assessed based on critical illnesses specifically covered in your contract at time of issue. Covered illnesses must meet specific definition requirements, and coverage is subject to exclusions and limitations.

Who is critical illness insurance for?   

CII is intended to help anyone manage financial costs due to a covered critical illness. 

Single people   

CII may help individuals maintain their independence by allowing them to pay for care services and other unexpected costs to manage their recovery.   

It can also help protect savings and RRSPs from unplanned withdrawals in the short term and retirement income in the long-term. 

Families with children 

Critical illness insurance for a child can help a family cope financially at a very stressful time if the child becomes seriously ill. 

By deciding to purchase critical illness coverage for your child early in life, you may provide them with: 

  • Guaranteed coverage as an adult 
  • Locked in lower premiums 
  • An opportunity for refund of premiums upon policy cancellation or expiry

Business owners   

CII can also help business owners in case of critical illness. The benefit from the insurance can assist with business continuity, debt repayment, and succession planning during an extended period away from the business.

Frequently asked questions

It depends on the product you're applying for. If you're applying online for Express Critical Illness Insurance, then you won't have to answer any medical questions or undergo a medical exam.

However, if you're applying for Sun Critical Illness Insurance, which offers coverage up to $4,000,000, you may need to complete a medical exam during the application process.

In Canada, there are no specific tax laws governing CII policies. The Canada Revenue Agency (CRA) has not developed its own position on the tax treatment of a benefit paid under a CII policy.

Talk to a tax professional for more information.

The most common type of waiting period for CII is the survival period. In Canada, if included, the survival period is usually 30 days. This means that, in some cases, you are required to survive a minimum of 30 days after the diagnosis of the covered illness before you can submit a claim and receive the benefit.

Other covered illnesses or diseases, such as cancer, require your coverage to be in effect for a certain amount of time before you're eligible for the benefit.

For full details, please familiarize yourself with your policy or connect with an advisor.

Our critical illness insurance products can cover carcinoma, melanoma, leukemia, lymphoma and sarcoma1. 

To receive a payout, you must have a cancer diagnosis confirmed by a specialist. It's important to note that the cancer definition has exclusions. Please refer to your contract or speak with an advisor.

It depends on the product you buy. 

Sun Critical Illness Insurance can cover you for your whole life, but Express Critical Illness Insurance won't.

Connect with an advisor for more detailed information

You may need critical illness insurance for a child if you think you can't afford all the expenses that may arise if your child is diagnosed with a covered critical illness.

For example, you may need to take time off work (resulting in income loss) to take care of your child. In such cases, a critical illness insurance plan for a child will give you a lump sum of money if your child ever gets one of the illnesses covered in the policy.

Here's how to find out if your children need critical illness insurance

The main difference between critical illness insurance and life insurance is how the insurance benefit is triggered.

CII benefits are paid out when you or the insured person has a covered critical illness and meets all of the contract requirements.

Life insurance benefits, however, are paid out to your estate or named beneficiary when you die.
