What Is Key Person Insurance and What Happens to Your Business Without It?

Most Canadian business owners insure their assets.

Their building. Their equipment. Their vehicles. Their liability.

Very few insure the thing that's actually driving most of the value, which is the people the business can't function without.

That's the gap key person insurance is designed to close. And for many smaller businesses, it's one of the most significant unaddressed risks in the plan.

What is key person insurance?

Key person insurance is a life or disability policy owned by the corporation on a specific individual whose loss would have a material financial impact on the business. That person is typically an owner, a founder, or someone who carries a disproportionate share of client relationships, technical expertise, or revenue generation.

The corporation pays the premiums and is the named beneficiary. If the key person dies or becomes disabled, the death or disability benefit is paid to the corporation, giving the business the financial capacity to manage what comes next.

Why it matters more than most owners expect.

Think about what actually happens to a business when it loses a key person unexpectedly.

Revenue that depended on that person's relationships starts to erode. Clients who trusted that individual may leave before a successor can be introduced. Projects stall. Operational knowledge that lived in one person's head becomes suddenly inaccessible.

At the same time, the business still has obligations. Rent. Payroll. Loan covenants. Contracts with delivery timelines. None of those pause because the business is in transition.

Key person insurance doesn't solve the operational problem. But it gives the business the financial runway to manage the transition without being forced into decisions, whether selling, borrowing, or cutting, before it's ready.

For business owners specifically, there's an additional layer.

If you are the key person, your death or disability affects more than the business operations. It affects the value of the asset your family is counting on. It affects your estate plan. It affects any buy-sell agreement with partners. It affects how your Holdco is structured and what your surviving spouse inherits.

Key person coverage in that context isn't just a business continuity tool. It's part of how the overall plan holds together when something goes wrong.

One more coverage most owners don't know exists.

Business overhead insurance is worth mentioning here because very few owners have it and most don't know it's available.

If you become disabled, business overhead insurance covers the fixed operating costs of your business while you're unable to work. Rent, utilities, staff salaries, loan payments. The expenses that continue whether you're there or not.

Personal disability insurance replaces your income. It doesn't cover what the business owes every month. Business overhead insurance fills that gap. For owners whose personal finances and business finances are closely connected, it's a meaningful protection that most people only discover when they wish they'd had it.

The businesses that survive the loss of a key person aren't lucky. They planned for it before it happened.

Whether key person insurance makes sense and what form it should take depends on the structure of the business, who the key people actually are, what the financial impact of their loss would realistically be, and how the coverage fits alongside other insurance and estate planning decisions.

That's not a decision that should be made in isolation from the rest of the plan.

If nobody has mapped the financial impact of losing your most important people, that's the starting point.
