Estate Freeze in Canada — Locking in Today's Value, Passing Tomorrow's Growth
A Mississauga business owner, 56, runs an industrial-services company that has grown from a $200,000 startup fifteen years ago to a present fair market value of $6 million. The owner expects the business to be worth $20 million by the time she retires in her late sixties or that her two adult children take it over. If she does nothing and dies in twelve years, her estate faces a deemed disposition at the then-fair-market-value of, perhaps, $20 million, and the federal-plus-Ontario tax on the embedded capital gain runs into the area of $4 million. The Lifetime Capital Gains Exemption shelters roughly $1.25 million of that gain (the indexed limit is $1,275,000 for 2026, subject to the eligibility rules and the type of property), leaving the rest exposed.
An estate freeze done today would lock the owner's share value at $6 million and shift the future $14 million of growth onto new shares held by a discretionary family trust with her spouse and two children as beneficiaries. At her eventual death (or sale), the deemed disposition is calculated on the frozen $6 million, and each of the four family members (or each of the children, plus the spouse on a separate transaction) can potentially claim their own LCGE on their share of the trust-allocated gain. The lifetime tax saving on a planned sale, after factoring in the freeze setup cost, often runs to several hundred thousand dollars on a transaction of this size.
The freeze is one of the most powerful tools in Canadian closely-held-business estate planning. It is also one of the most over-prescribed, sometimes locking families into structures that don't fit their actual goals. For the broader picture of how the freeze fits into the plan, see our pillar on estate planning in Canada and our companion guide on the Lifetime Capital Gains Exemption.
What the freeze actually does, in plain terms
Inside a closely held Canadian corporation, the owner typically holds common shares — the class of shares that participates in the company's growth in value. When the owner dies, the Income Tax Act treats the death as a deemed disposition of those shares at fair market value, and the embedded gain on the shares is taxable on the final return.
An estate freeze restructures the share capital so that:
-
The owner's growth shares are converted into fixed-value preferred shares. The new preferred shares have a redemption value equal to today's fair market value of the company. They participate in dividends, can be redeemed by the company, but do not grow in value. The owner's deemed-disposition exposure at death is now capped at today's value.
-
New growth shares are issued. These typically go to a discretionary family trust holding shares for the spouse, children, and sometimes other relatives, or in some structures directly to adult children. The new shares carry the future growth in the company's value.
-
Voting control is retained by the freezor. Common structures issue voting preferred shares to the freezor, so the original owner retains control over corporate decisions (board appointments, major sales, dividend declarations) even though their economic interest is now capped.
The two main statutory mechanisms used in Canada are section 86 of the Income Tax Act (a reorganisation of share capital within the same corporation) and section 85 (a transfer of shares to a new corporation in exchange for shares of the new corporation).[1][2] Both achieve the same economic result through different mechanical paths.
The family trust component
Most Canadian estate freezes pair the share reorganisation with a discretionary family trust to hold the new growth shares. The trust structure does several things:
Multiplies the LCGE. Each beneficiary of the trust who is a Canadian resident can potentially claim their own LCGE on capital gains allocated from the trust to them, subject to the QSBC test on the underlying shares.[3] A family of four can in principle shelter well over $5 million of capital gain on the eventual sale (four times the $1,275,000 2026 exemption) — subject to each individual meeting the eligibility rules and the property qualifying (QSBC shares, or qualified farm or fishing property).
Provides post-freeze flexibility. The trustees have discretion to allocate income and capital among the beneficiaries. If one child becomes involved in the business and another doesn't, the trustees can reflect that economic reality in allocations.
Protects against beneficiary creditor claims. Assets held in a discretionary trust are generally not available to a beneficiary's creditors or to a former spouse on a marriage breakdown — until the trustees actually distribute.
Defers the tax on growth. Income earned and capital gains realised in the trust can be allocated to beneficiaries in their year of receipt, generally taxed in the beneficiary's hands at the beneficiary's marginal rate rather than the trust's top rate.
The trust deed has to be drafted carefully — too much trustee discretion can run afoul of CRA anti-avoidance rules (attribution rules), and too little discretion limits the value of the structure.
The 21-year deemed disposition rule
A personal trust is deemed to dispose of its capital property at fair market value on the 21st anniversary of its creation.[4] For a family trust established as part of an estate freeze, this means the trust-held growth shares face a deemed taxable disposition at the 21-year mark, regardless of whether they have been sold.
Two standard responses:
- Roll out the shares to beneficiaries before the 21st anniversary. Subsection 107(2) of the Income Tax Act allows the trustees to distribute trust-held shares to beneficiaries on a tax-deferred basis, at the trust's adjusted cost base.[5] Once the shares are out of the trust, the 21-year rule no longer applies to them.
- Plan the sale or refinancing around the 21st anniversary. Some families time a planned sale of the business or a refinancing event close to the 21st anniversary to use the LCGE on the planned event rather than face the deemed disposition.
The 21-year wind-down is a major planning event in its own right. Trusts established in 2005 for freezes done at that time are now passing through the 21-year mark in 2026 with significant accumulated value, and the planning for the rollout has been complex.
When a freeze isn't worth it
Three situations where the freeze is more trouble than it's worth:
- The business is unlikely to grow much. If the company's value has plateaued, the freeze locks in the current value but shifts no meaningful growth — the cost of the freeze plus the trust outweighs the tax benefit.
- The owner needs the future growth for retirement income. A freeze gives away future appreciation. If the owner anticipates needing the business's growth in value to fund retirement, the freeze either has to be paired with a meaningful liquidity event (selling some preferred shares back to the company for cash) or shouldn't be done at all.
- The next generation is uncertain. Issuing growth shares (directly or through a trust) to children who may never want or be capable of running the business creates ownership structures that are difficult to unwind. Some families do a freeze, then have to negotiate a buyout of the growth shares from disengaged children years later — at the same value the freeze was trying to shelter.
The cost picture
Setting up a typical Canadian estate freeze costs roughly $15,000 to $40,000 in 2026 dollars for legal and accounting fees, depending on the corporate structure's complexity and whether a family trust is included. Ongoing annual costs (T3 trust returns, trustee meetings, legal review) typically run $3,000 to $8,000.
The break-even economic threshold is meaningful — the freeze is generally worth doing when the expected future growth in the business is in the millions of dollars and the family has a multi-decade ownership horizon. Below that, simpler tools (a clean will, beneficiary designations on insurance, basic share-class structuring) often deliver enough of the benefit without the structural commitment.
What we focus on at It's Simple Will
The estate freeze is firmly in advisor-and-lawyer territory — the corporate reorganisation, the family trust deed, the tax elections, the ongoing trustee filings all require professional help that goes well beyond the will-and-POA work that DIY tools handle. The Will Creator handles the personal estate planning that runs alongside the corporate structure — the will, the powers of attorney, the personal asset disposition. The Life Discovery Kit captures the corporate advisors' contact details and notes for the executor about which shares are held by the family trust versus the personal estate. Our companion guide on the LCGE walks the exemption mechanic that the freeze is usually built to maximise.

Frequently asked questions
When does an estate freeze make sense?
A freeze is most useful when the business is expected to grow in value, the owner wants to retain control during life but pass future growth to family members or other heirs, and the family is willing to commit to a long-term ownership structure. The freeze caps the owner's tax exposure at the current value (the deemed disposition at death will be calculated on that frozen value, not the company's future fair market value), and growth accrues to the next generation in a way that allows multiple Lifetime Capital Gains Exemptions to be used at the eventual sale.
What is the difference between a section 86 and a section 85 freeze?
A section 86 reorganisation exchanges the owner's existing common shares for new fixed-value preferred shares of the same corporation, on a tax-deferred basis, without bringing in any new corporation. A section 85 rollover is more flexible — the owner transfers shares into a new holding corporation in exchange for fixed-value preferred shares, which can be useful when the corporate group needs restructuring at the same time. Both achieve the same economic freeze; the choice depends on the existing corporate structure and the planning goals.
Does the freeze trigger immediate tax?
Generally no, if the section 86 or section 85 conditions are met. The transaction is a tax-deferred rollover — the owner's adjusted cost base and any unrealised gain transfer onto the new preferred shares. The freeze does not crystallise the gain at the time of the freeze unless the owner specifically elects to do so (sometimes called a "freeze with crystallisation" — used to claim some LCGE up front, locking in the higher cost base).
What is a family trust's role in an estate freeze?
The new growth shares are typically issued not to family members directly but to a discretionary family trust that has the spouse, children, and sometimes other relatives as beneficiaries. The trust holds the growth shares; the trustees decide how to allocate future income and gains among the beneficiaries. This structure provides flexibility — beneficiaries can be added or removed by the trustees, gains can be allocated to family members in lower tax brackets, and on a sale of the business each beneficiary can potentially claim their own LCGE on the allocated capital gain.
What is the 21-year rule and why does it matter?
A personal trust (including a family trust) is deemed to dispose of its capital property at fair market value on the 21st anniversary of its creation. The deemed disposition triggers tax on accumulated gains as if the trust had sold the assets. Family trusts established for estate freezes generally distribute their assets to beneficiaries before the 21-year mark to avoid this tax — usually by rolling out the trust-held shares to the beneficiaries directly under subsection 107(2). Planning for the 21-year wind-down is part of the freeze planning.
Can I undo or refreeze the structure later?
A "refreeze" — replacing the original frozen preferred shares with new preferred shares at a lower value — is possible if the business has declined in value since the original freeze, locking in the lower deemed-disposition exposure. Unwinding the freeze entirely is more complex; once the family trust holds growth shares, the trust is a separate taxpayer with its own assets, and dismantling the structure can trigger gains in the trust. Estate freezes are durable structures; the decision to put one in place generally assumes a multi-decade horizon.
