Estate Freeze Explained: How It Works in Canada and How the Owner Gets Paid

An estate freeze is the planning move most often paired with a family trust. You exchange your common shares of a company for preferred shares fixed at today's value, and new common shares, often held by a trust, take the growth from then on. The appeal is easy to state: the value taxed on your death stops rising, you can keep control, and the trustees can decide later which family members benefit. This post also covers what a freeze does not do, and the question that matters once you retire: how you actually get paid from shares whose value is frozen.

First, the constraint. For an Ontario medicine or dentistry professional corporation, a standard family trust, one whose beneficiaries include people or companies outside a narrow permitted class, cannot own the corporation's shares, so the classic freeze in favour of a trust does not work for the professional corporation itself. This post is about a company that is not subject to those rules: a separate corporation that owns your clinic building or provides non-clinical management services, a spouse's business, or any other private company. It is orientation, not advice, and the family trusts guide covers the wider picture. Your accountant and lawyer decide what applies to your family.

The freeze in three steps, with numbers

The figures are a hypothetical example. You own all 100 common shares of a company worth $900,000. Your adjusted cost base, the tax cost of the shares, is $100,000, so $800,000 of gain has built up.

1. You exchange your common shares for preferred shares. You receive 100 preferred shares that can be redeemed for a fixed $900,000, the company's value today. Done as a reorganization of the company's share capital, the exchange is generally not taxed: the new shares take over the old shares' $100,000 cost. The preferred shares need a professional valuation and a clause that adjusts their redemption price if the CRA later disagrees with it. If they turn out to be worth less than the shares you gave up, and the difference benefits a family member, part of your gain can be taxed immediately.
2. A family trust is created. A settlor, usually someone other than you, settles a discretionary trust. The trustees often include you and others, and the beneficiaries often include your spouse, your children, future generations and sometimes a company.
3. The trust subscribes for new common shares. The trust buys 100 new common shares for $100, their nominal value, because the preferred shares already carry the company's current value. That $100 should not come from you: income and gains on property you contribute to a trust can be taxed back to you if the property can return to you or you control who receives it.

Fifteen years later, still hypothetically, the company is worth $3,900,000:

What the freeze achieves

• Your gain stops growing. At death you are deemed to sell your shares at fair market value. Without the freeze, your shares would be worth $3,900,000, a gain of $3,800,000, and the capital gains tax on your final return would be up to about $1.02 million if the whole taxable half were taxed at the 2026 top Ontario rate of 53.53 percent. With the freeze, the gain is $800,000 and that tax is up to about $214,000. Both figures are illustrations under the example's assumptions, before any capital gains exemption, and a rollover to a surviving spouse can defer the gain until a later actual or deemed disposition.
• Control can stay with you. A common design gives you voting shares with nominal value but many votes, sometimes thousands per share, so voting power is separated from value. Whether you keep control depends on how the voting shares are structured, not on the freeze itself.
• Your death is not a tax event for the trust. The trust is a separate taxpayer. Its common shares are not deemed sold because you die, so the growth on them is not taxed on your final return. That is where the long-term deferral comes from.
• Who benefits can be decided later. In a discretionary trust, the trustees decide which beneficiaries receive income or capital, within the trust's terms and before its 21st anniversary.
• The lifetime capital gains exemption can be multiplied, under conditions. If the trust later sells qualifying shares, ones that meet the tests for qualified small business corporation shares, it can allocate the gain to several beneficiaries, each claiming their own exemption, up to $1,275,000 each in 2026 if they have not used it. Shares the trust subscribes for are generally treated as held by an unrelated person before they were issued, so the 24-month holding test generally starts when the trust subscribes. Companies holding mainly investments fail the asset tests. A minor's gain is treated as a dividend instead, with no exemption, if the shares are sold to a buyer who does not deal at arm's length with the minor, and the alternative minimum tax can apply in the year of a large exemption claim.

What it does not do

A freeze fixes the value of your shares, not your tax bill. The accrued $800,000 capital gain remains relevant on a sale or at death. Redemptions generally trigger dividend taxation instead, as explained below. The $2,999,900 of growth in the trust is not tax-free either: it is taxed when the trust or a beneficiary eventually disposes of the shares, or at the trust's 21-year deemed disposition if the trust still holds them then. The freeze moves the growth and defers its tax. It does not erase it.

Nor does it bring back income splitting. Dividends paid on the trust's common shares and allocated to your spouse or children are generally taxed at the top rate under the tax on split income, unless an exception applies, such as an adult who genuinely works in the business. The post on family trusts after TOSI explains the exceptions.

One more rule catches freezes in particular. Corporate attribution targets a transfer to a company where one of the main purposes can reasonably be considered to be reducing your income and benefiting your spouse or a minor family member. It can apply when your spouse, or a child, grandchild, niece or nephew under 18, is a beneficiary who counts as owning at least 10 percent of a class of the company's shares (a discretionary beneficiary is treated as owning every share the trust holds), and the company is not a small business corporation, for example because most of its value is an investment portfolio. You are then deemed to receive interest each year at the prescribed rate on the value you froze, reduced by the taxable amount of ordinary dividends you receive on your preferred shares. Deemed dividends from redemptions do not reduce it. As an annualized illustration, at 3 percent for the whole year, the deemed interest on $900,000 would be $27,000 before any offsets. Trust terms that prevent those beneficiaries from receiving income or capital while they remain in that group, and administration that matches, can avoid it.

How you actually get paid from frozen shares

Your value now sits in preferred shares that do not grow. Turning them into retirement income is the part freeze explanations often skip.

• Dividends on the preferred shares. Freeze shares often carry a right to dividends up to a set annual rate, paid when the directors declare them. The company pays you while it has the earnings, and you pay tax at dividend rates.
• Redeeming shares over time. The company buys back some of your preferred shares each year, out of its earnings. Each redemption is generally taxed as a dividend on the amount above the shares' paid-up capital, and after a freeze that paid-up capital is usually small, so most of every payment is a dividend. Because each redemption reduces the frozen value, it also reduces the gain left to be taxed at your death. Spread over retirement years with little other income, those dividends may be taxed at lower rates, but at the top bracket a non-eligible dividend, taxed at 47.74 percent in Ontario for 2026, costs more per dollar than a capital gain, of which only half is taxed.
• The exemption does not apply to redemptions. Because a redemption is taxed as a dividend rather than a capital gain, your lifetime capital gains exemption cannot shelter it. The exemption is a lifetime amount and can be used across several years, but only against capital gains on qualifying shares, such as on a sale to an arm's-length buyer.
• Crystallizing at the freeze. If your shares qualify when you freeze, the exchange can instead be done under a rollover provision that lets you realize a gain up to your remaining exemption on purpose. The exemption shelters that gain, and your preferred shares get a higher cost base, which reduces the gain taxed later. It works only for shares that qualify at that time, and the alternative minimum tax can apply in that year.

A freeze can be repeated

A freeze is not a one-time event. Before its 21st anniversary, the trust can freeze its own common shares, exchanging them for preferred shares so that later growth goes elsewhere. A second freeze redirects later growth, but does not remove the accumulated gain or reset the trust's 21-year date. Preferred shares retained by the trust remain subject to that deadline. The 21-year rule post explains how that fits with the anniversary. Children who eventually hold the growth shares can freeze in favour of their own families in turn. Each freeze needs its own valuation and legal work.

Tax at death, twice

After your death, your estate owns the frozen preferred shares with a cost equal to their value at death, but their paid-up capital is usually still small. If the company then redeems them or winds up, the payout can be taxed again as a dividend, on top of the capital gains tax on your final return. Accountants commonly address this in one of two ways. If a graduated rate estate redeems the shares within its first three taxation years, your executor can elect, in prescribed form by the estate's filing-due date for that year, to carry the resulting capital loss back to your final return, so the value is taxed once, as a dividend. Or a pipeline: the estate transfers the shares to a new company for a promissory note and is repaid over time, so the value is taxed once, as the capital gain on your final return. Both have conditions and anti-avoidance limits that your accountant needs to design around.

Where insurance fits

A freeze makes the tax at your death easier to estimate, not fixed. Under the example's assumptions, the capital gains tax on your final return from the frozen shares is up to about $214,000, an estimate that no longer grows with the company. The eventual bill still depends on tax rates, any exemption claimed, redemptions before death and the plan your estate follows afterward, such as a loss carryback that replaces that capital gains tax with dividend tax. Life insurance pays at death, so it is one way to fund the bill without forcing a sale. Level coverage sized to the estimated need can suit it, reviewed periodically as those factors change, and a design that builds little cash value can fit that single purpose. Other assets that keep growing outside the freeze, such as a cottage or an investment portfolio, may call for coverage that can grow. Insurance funds the tax at death only. The trust's 21-year date needs its own plan.

Who owns the policy matters. When a private corporation receives the death benefit as beneficiary, the proceeds less the policy's adjusted cost basis are generally added to its capital dividend account, which lets it pay that amount to shareholders tax-free, as the corporate-owned life insurance guide explains. After a freeze, cash value built up in a policy owned by the frozen company adds to the value of the common shares held by the trust, not to your frozen shares. A policy owned by the trust on your life is possible: in Ontario, a policy is not void for lack of insurable interest if the person insured consents in writing. The harder question is paying for it. The trust needs money for premiums, and money you give it can bring the attribution and reversionary trust rules into play.

Questions for your accountant and lawyer

1. Is this company a professional corporation, or one a family trust can own?
2. What is the company worth today, and who will value the preferred shares?
3. How will I keep control, and who will the trustees be?
4. Where will the trust's subscription money come from?
5. Is the company a small business corporation, and are my spouse or minor children beneficiaries?
6. How will I draw income from the preferred shares: dividends, redemptions or a sale?
7. What is the estimated tax at my death, and what is the plan for the trust's 21st anniversary?

I do not set up trusts or estate freezes. Your lawyer drafts the trust and the share changes, a valuator values the company, and your accountant designs the tax side. This post is orientation, so you can walk into those meetings knowing what a freeze can do, what it cannot, and how you will be paid from it. Where I can help is the part it leaves behind: the tax at death, and how it will be paid.
