What key person insurance is, in plain language
Key person insurance is a life insurance or critical illness policy a company buys on someone whose death or serious illness would do real financial damage to the business. The corporation owns the policy, pays the premiums, and receives the benefit. The cash replaces lost profit, reassures lenders, and funds the search for and training of a replacement. Key man insurance is the older name for exactly the same coverage.
That is the whole idea. The business, not the family, is the beneficiary, because it is the business that takes the financial hit. If you are looking for protection for your family rather than your company, start instead with our pillar on high net worth life insurance in Canada. The two conversations overlap, but they are not the same conversation.
Who counts as a key person
This is not a job title test. A key person is anyone whose absence would crater revenue, stall production, walk the top client relationships out the door, or trip a covenant on a bank loan. In an owner-managed business that almost always includes the owner. It often includes a co-owner, a rainmaker who holds the major accounts, or a long-tenured operations lead nobody could replace in under a year.
A simple gut test works better than any formula. Whose name, if it appeared in an obituary, would make your banker pick up the phone? That person is key.
What the money actually does
When the policy pays, the corporation receives a lump sum of cash at exactly the moment the business is wounded. That cash has four jobs.
- Replace lost profit. Revenue tied to the key person does not come back overnight. The benefit bridges the gap.
- Fund the replacement. Recruiting, signing, and training a successor costs real money, often over more than a year.
- Keep lenders and suppliers calm. A funded continuity plan is the difference between a bank that waits and a bank that calls the loan. Some lenders now require coverage, with the policy assigned as collateral, as a condition of the operating line or term loan.
- Fund a share buyout. If a shareholders' agreement obliges the company to buy out a deceased owner's shares, the policy is often the cheapest way to fund that obligation. Family businesses sorting out which child gets the company and which gets cash should also read our page on estate equalization with life insurance.
How much coverage the company should buy
There is no single right number, but there are three honest ways to get to one. In practice we run all three and take the number that actually protects the business.
Multiple of salary
The rough-cut method. Take the key person's total compensation and multiply it, commonly somewhere in the range of five to ten times. It is quick, and carriers like it because it is easy to underwrite. It is also blunt. Salary often understates what an owner or rainmaker is actually worth to the business, especially in a company where the owner deliberately keeps their own pay low.
Contribution to profit
The more honest method for an owner-managed business. Ask what share of revenue or gross margin walks out the door with that person, and how many years it would take to rebuild it. Suppose a key salesperson holds relationships behind $3,000,000 of annual gross margin, and a realistic rebuild takes three years at declining losses. The numbers are illustrative, but the method is the point. You are insuring the profit at risk, not the paycheque.
Buyout and lender requirements
Sometimes the number is set for you. If a shareholders' agreement requires the company to buy a deceased owner's shares, the coverage has to match the share value, and that value needs to be kept current. If a lender requires a policy assigned against a loan, the loan balance sets a floor. When more than one of these applies, the coverage needs to be sized so that paying the bank does not leave the buyout unfunded.
Sizing is where a CPA-led process earns its keep. We work from your statements, not a rule of thumb. You can see how that works in our process.
Life insurance, critical illness, or both
Key person life insurance
The classic version. The corporation owns a life policy on the key person and receives a tax-free death benefit if they die. Term coverage is common where the need is tied to a loan or a working horizon. Permanent coverage can make sense where the policy also serves a longer corporate planning purpose, which connects to the wider strategy on our pillar covering corporate-owned life insurance for Canadian business owners.
Key person critical illness insurance
During working years, a serious illness is the statistically likelier event. A critical illness policy pays the corporation a lump sum on diagnosis of a covered condition such as cancer, heart attack, or stroke, while the key person is still alive. That timing matters. The business is now paying the key person's salary and a replacement's salary at the same time, with revenue under pressure. We cover the corporate version of this coverage in depth on our page about corporate-owned critical illness insurance.
Why many owner-managed businesses carry both
Death and serious illness are different events with different cash needs. A death benefit funds a permanent transition. A critical illness benefit funds a temporary one that may run for years. Many businesses carry a layer of each, sized separately, so the plan matches the event rather than hoping one policy stretches to cover both.
The tax treatment, without the gloss
Premiums are generally not deductible
The carrier product pages tend to bury this, so here it is plainly. Premiums on key person coverage are generally not deductible to the corporation. The company pays them with after-tax corporate dollars. A narrow exception can apply where a lender requires the policy and it is assigned as collateral for a loan, in which case a portion of the premium may be deductible. The rules on that exception are specific, so it is a question to settle with your accountant before counting on it.
The death benefit arrives tax-free, and credits the CDA
Here is the part that changes the math. The corporation receives a life insurance death benefit tax-free. And the death benefit, minus the policy's adjusted cost basis, credits the company's Capital Dividend Account. That means any portion of the benefit the business does not need for continuity can later be paid out to shareholders as a tax-free capital dividend. A policy bought purely to protect the business can end up moving wealth to the family with no tax on the way out. The product pages never explain this. It is exactly the kind of outcome a CPA-led advisor models before the policy is placed, because beneficiary designation and ownership structure have to be right for the credit to land.
Who this is for, and who it is not for
Key person insurance fits owner-managed and family businesses where revenue, operations, or a bank covenant depends on one or two people. If your banker, your biggest customer, or your own honest assessment says the business would struggle badly without a specific person, this coverage belongs in the plan.
It is not for everyone. If no single absence would really move the numbers, the premium is better spent elsewhere, and we will say so. And if what you actually want is protection for your family rather than the company, that is a different structure and a different page. Accountants and lawyers bringing a client case to us can also work through our referral partnership for CPAs and advisors.

Common questions
What is the difference between key person insurance and key man insurance?
Nothing. Key man insurance is the older name for the same coverage. Either way, it is a life or critical illness policy the corporation owns on someone whose death or serious illness would damage the business, with the corporation paying the premiums and receiving the benefit.
Are key person insurance premiums tax deductible in Canada?
Generally no. The corporation pays the premiums with after-tax dollars. A narrow exception can allow a portion of the premium to be deducted where a lender requires the policy and it is assigned as collateral for a loan. Because the conditions are specific, confirm the treatment with your accountant before relying on it.
How much key person insurance does a small business need?
Three methods give you the range. A multiple of the key person's salary is the quick estimate. Their contribution to profit, meaning the margin at risk and the years needed to rebuild it, is usually the more accurate one for an owner-managed business. Buyout obligations under a shareholders' agreement and lender requirements can set the number outright. A sound plan checks all three.
Does key person insurance cover illness or just death?
Both are available. Key person life insurance pays the corporation a tax-free death benefit at death. Key person critical illness insurance pays a lump sum while the person is alive, on diagnosis of a covered condition. During working years a serious illness is the likelier event, which is why many businesses carry both types.
Who receives the money from a key person policy?
The corporation. It owns the policy, pays the premiums, and is the beneficiary. Getting that structure right matters beyond the payout itself, because on a life policy the death benefit minus the policy's adjusted cost basis credits the company's Capital Dividend Account, which can later move surplus to shareholders tax-free.
