Estate Freeze
An estate freeze is a reorganization in which the owner of a Canadian private corporation exchanges their common shares for fixed-value preferred shares equal to the current fair market value of the shares given up, so that new common shares issued to children, a family trust, a holding company or key employees capture all future growth. The owner's value, and the tax on it at death, is capped at today's amount. Freezes are usually tax-deferred under section 86 or section 85 of the Income Tax Act. An Ontario corporation files articles of amendment under the OBCA if its articles do not already authorize the freeze shares.

Key Takeaways
- An estate freeze exchanges an owner's common shares for fixed-value preferred shares so that future growth in a private corporation goes to new shareholders instead of the owner's estate.
- Freeze shares are usually redeemable and retractable at the freeze-date fair market value, rank ahead of the common shares and carry a price adjustment clause.
- A section 86 freeze happens automatically on a reorganization of capital, while a section 85 freeze uses a joint T2057 election that lets the owner choose the elected amount.
- In Ontario, the articles must authorize the freeze shares, which often means filing articles of amendment approved by special resolution.
- Valuation errors, the tax on split income rules, corporate attribution and the 21-year deemed disposition for family trusts are the main points to plan around.
What Is an Estate Freeze?
When a Canadian business owner dies, the Income Tax Act treats their capital property, including private company shares, as sold at fair market value immediately before death (subsection 70(5)), unless it passes to a spouse or a spousal trust. If the company keeps growing, so does the tax bill the estate inherits.
An estate freeze caps that exposure. The owner, called the freezor, exchanges their common shares for preferred shares with a fixed value equal to what the company is worth today. New common shares, issued for a nominal price, go to the people who will own the future. Every dollar of growth after the freeze date accrues to those new common shares, not to the freezor's estate.
A freeze is not a sale. The freezor receives no cash, keeps the frozen value, can keep voting control, and can draw income through dividends on, or redemptions of, the preferred shares. It is often the first step toward a later intergenerational business transfer or another succession route, such as the employee ownership trust option now available to Canadian owners.
Section 86 vs. Section 85 Freezes
Two provisions of the Income Tax Act let the exchange happen without immediate tax.
| Section 86 freeze | Section 85 freeze | |
|---|---|---|
| Mechanism | Owner exchanges all their shares of a class for new shares of the same corporation in a reorganization of capital | Owner transfers shares to the same corporation, or to a new holding company, for preferred shares |
| Election | None; applies automatically | Joint election on Form T2057 |
| Tax cost of new shares | Carries over from the old shares | Set by the elected amount, between tax cost and fair market value |
| Common use | Simple internal freeze of an operating company | Holding company freeze, or a freeze combined with crystallizing the capital gains exemption |
Section 86 applies only where the owner disposes of all of their shares of the class, and it does not apply if a section 85 election is filed for the same shares. A section 85 rollover gives more control because the parties choose the elected amount, which lets an owner of qualifying shares trigger a gain sheltered by the lifetime capital gains exemption at the same time as freezing.
In a holding company freeze, the owner rolls operating company shares into a holdco for holdco preferred shares, and the next generation or a family trust subscribes for new common shares, usually of the holdco, so that future growth in the operating company accrues to them. Taking cash or a note as part of that exchange can trigger section 84.1 and a deemed dividend, so holdco freezes are normally share-for-share.
Cautions Before You Freeze
- Valuation. If the freeze shares are worth less than the shares given up and the difference benefits a related person, subsection 86(2) or paragraph 85(1)(e.2) creates an immediate gain. Undervaluing to shift more growth defeats the plan.
- Tax on split income. Dividends on growth shares paid to family members can be taxed at the top marginal rate under the TOSI rules unless an exclusion applies, such as active involvement in the business.
- Corporate attribution. Where one of the main purposes of a freeze is to benefit a spouse, or a minor child, grandchild, niece or nephew, and the corporation is not a small business corporation, section 74.4 can deem the freezor to receive interest income each year at the prescribed rate.
- Retirement income. The freezor's wealth from the company is capped at the frozen value. Owners who will need more may freeze only part of their shares.
- Control and exit terms. A shareholder agreement among the next-generation owners should cover transfers, buyouts and what happens if a child leaves the business.
As of October 2026, the capital gains inclusion rate remains one-half; the increase proposed in 2024 was cancelled in March 2025.
Practical Example
Gordon Pereira, 61, owns all 100 common shares of Pereira Fabrication Ltd., an Oakville metal fabrication company. In March 2026 a Chartered Business Valuator values the company at $4,000,000. His daughter Alicia runs operations and his son Marco manages sales; both expect to own the business one day.
Using section 86, the company amends its articles to create voting preferred shares redeemable and retractable at $1 each, and Gordon exchanges his 100 common shares for 4,000,000 of them, with a price adjustment clause. A newly settled discretionary family trust, with Alicia, Marco and Gordon's grandchildren as beneficiaries, subscribes for 100 new common shares at $1 each, using funds that did not come from Gordon. Some grandchildren are minors, but because the company is a Canadian-controlled private corporation with substantially all its assets used in its active business, it is a small business corporation and the corporate attribution rule does not apply while that remains true.
By 2036 the company is worth $7,000,000. The $3,000,000 of growth belongs to the common shares held by the trust, not to Gordon. His preferred shares are still worth no more than $4,000,000, less any he has redeemed to fund his retirement, so his estate's deemed disposition for this company is capped at that amount. Gordon keeps voting control throughout, and the trustees can later distribute the common shares to whichever children are running the business, well before the trust's 21-year deemed disposition date.
Frequently Asked Questions
Does an estate freeze eliminate tax on death?+
No. It caps the amount. The freezor is still deemed to dispose of the preferred shares at fair market value on death, so the gain that accrued up to the freeze date is taxed, unless the shares pass to a spouse or spousal trust. What the freeze removes from the estate is tax on growth after the freeze date, which becomes the new shareholders' gain instead.
Can I still control my company after an estate freeze?+
Yes. Freeze shares can carry votes, or the freezor can hold a separate class of voting shares with little value, so control of the board stays with the owner while the economic growth belongs to the next generation. Control and value are separate design choices, and a shareholder agreement usually sets out when and how control will pass.
When is the right time to do an estate freeze?+
Generally when the business is expected to keep growing and the owner has enough value to fund retirement from the frozen shares. Freezing earlier shifts more growth, but a freeze done before the next generation's roles are clear can lock in the wrong owners. A temporary dip in value can also be an opportunity, because the frozen amount is lower.
Can an estate freeze be reversed or redone?+
Partly. If the company's value falls below the frozen amount, owners sometimes exchange the freeze shares for new preferred shares at the lower value, a step called a refreeze. Undoing a freeze to recapture growth from children or a trust is far harder, because it can shift value between family members and raise tax and family issues. Plan as though the freeze is permanent.
What is the difference between an estate freeze and a family trust?+
An estate freeze is the transaction that fixes the owner's value and creates growth shares. A family trust is one possible holder of those growth shares. Many freezes use a discretionary family trust so the trustees can decide later which family members benefit, but others issue the growth shares directly to adult children or to their holding companies. A freeze can be done without a trust, and a trust can exist without a freeze.
