Critical Illness Insurance for Business Owners and Corporations
When the owner is the business, a serious illness stops both. Critical illness insurance pays a lump sum on diagnosis, and your corporation can own it, pay for it or share it with you.
How critical illness insurance protects a business
Critical illness insurance pays a one-time lump sum if you're diagnosed with a covered condition, such as cancer, a heart attack or a stroke. For a business owner it can keep the company running, fund a buyout, or replace what you can't earn while you recover. Who owns the policy decides how premiums and the benefit are treated for tax.
- A lump sum on diagnosisPaid once a covered condition is diagnosed and a survival period set by the policy has passed, often 30 days for some conditions.
- Four ways to hold itKey person, buy-sell funding, personal coverage paid by the corporation, or shared ownership.
- Ownership decides the taxWho pays and who receives changes how premiums and benefits are treated.
- No capital dividend account creditUnlike life insurance, a critical illness benefit can't flow out of the corporation tax-free.
Four ways a corporation can use critical illness insurance
Each one starts with a different need, and each is owned and taxed differently.
Key person coverage
The corporation owns, pays for and receives the benefit if a key person is diagnosed, to cover lost revenue or a replacement while they recover. Premiums are generally not deductible.
Key person insuranceBuy-sell funding on illness
If the shareholder agreement includes a critical illness trigger, the benefit can help the other owners buy a seriously ill partner's shares.
Buy-sell insuranceYour personal coverage, paid by the corporation
The corporation pays, but you own the policy and receive the benefit. The premium is then a taxable benefit to you, as employment income or a shareholder benefit.
Compare the optionsShared ownership
The corporation owns the critical illness benefit and you own the return of premium rider, each paying a fair share under a written agreement.
How shared ownership worksWho should own the policy?
Ownership decides who pays, who receives the money and how each part is taxed. Points marked "generally" reflect industry practice without published CRA guidance, so your accountant confirms them.
| Set-up | Who pays | Who receives the benefit | Tax on the premium | Tax on the benefit |
|---|---|---|---|---|
| You own and pay | You, with after-tax dollars | You | Not deductible | Generally received tax-free |
| Corporation owns, pays and receives (key person, buy-sell) | The corporation | The corporation | Generally not deductible | Generally treated as not taxable when received; taxable when paid out to you |
| Corporation pays, you own and receive | The corporation | You | A taxable benefit to you | Generally received tax-free |
| Group coverage for employees | The employer | The employee | A taxable benefit to the employee, reported on the T4 | Generally received tax-free |
| Shared ownership | Each its own share | Corporation: the benefit. You: the return of premium | A fair split, or a taxable benefit | Tax on the refund is not settled |
When the corporation receives the benefit
Insurers generally treat a critical illness benefit paid to a corporation as not taxable, because the Income Tax Act has no rule that taxes it. The Canada Revenue Agency has not published guidance on this point, so confirm it with your accountant.
Fund a buyout
If the shareholder agreement allows it, the benefit can help the other owners buy a seriously ill partner's shares at a fair price.
Getting it to you is different
A critical illness benefit doesn't create a capital dividend account credit, which only life insurance proceeds received on a death can do. Paying the money out to you is taxable, as a dividend or a shareholder benefit.
Return of premium and group coverage
Two features owners ask about, and what to check before relying on them.
Return of premium
An optional rider that refunds premiums if no critical illness claim is paid: on surrender after a set period, often 10 to 15 years, on expiry, or on death, depending on the policy. It adds cost. The Canada Revenue Agency has not issued a formal ruling on how these refunds are taxed. Many advisors expect a refund of after-tax premiums to be tax-free, but this is not settled.
Ask your accountant: how would a refund be taxed in our set-up?
Group critical illness for employees
Premiums an employer pays for group critical illness coverage are a taxable benefit to employees, reported on the T4. That is different from group health and dental, which are generally not taxable. Many employers still offer it as a valued benefit.
Watch for schemes
In December 2025 the Canada Revenue Agency warned about schemes in which a shareholder borrows money, lends it to the corporation, and the corporation buys a critical illness policy, often offshore, so the shareholder can draw funds out tax-free. It said it will reassess participants and may penalize promoters and advisors. A legitimate arrangement starts with a real insurance need, not a way to move money out.

Questions business owners ask about critical illness insurance
Yes, but it changes the tax. If the corporation owns the policy and receives the benefit, the premiums are generally not deductible and the money stays in the company. If the corporation pays for a policy that benefits you, the premium is generally a taxable benefit to you.
Insurers generally treat it as not taxable when received, because the Income Tax Act has no rule that taxes it, but the Canada Revenue Agency has not published guidance on this point. Paying the money out to you personally is taxable.
Generally no, when the corporation owns the policy for key person or buy-sell protection. Premiums the corporation pays for coverage that benefits an employee or shareholder are treated as a taxable benefit to that person, and your accountant confirms how they are recorded.
Yes, if the shareholder agreement includes a critical illness trigger. The benefit can then help the remaining owners buy a seriously ill partner's shares at a fair price. Your lawyer drafts the trigger.
No. Only life insurance proceeds received on a death create a capital dividend account credit. A critical illness benefit paid to a corporation reaches shareholders as a taxable dividend or benefit.
It is not settled. The Canada Revenue Agency has not issued a formal ruling, and in a shared ownership arrangement whether a refund creates a taxable benefit depends on the facts. Get written tax advice before relying on it.
A policy co-owned by the corporation and you. Typically the corporation owns the critical illness benefit and you own the return of premium rider, each paying a fair share of the premium under a written agreement.
