An estate freeze is one of the most powerful tax planning strategies available to Canadian business owners. At its core, it locks in (freezes) the current value of a business in the owner's hands, while transferring future growth to the next generation — typically through a family trust or directly to children. This reduces the capital gains tax that will be triggered at the business owner's death.
Why Business Owners Need Estate Freezes
When a business owner dies, deemed disposition rules treat them as having sold all their shares at fair market value. If the business has grown substantially, this can trigger millions of dollars in capital gains tax — potentially forcing a sale of the business or significant asset liquidation to pay the tax bill.
Without an estate freeze:
Business founder owns 100% of Opco shares, ACB = $100,000
FMV at death = $5,000,000
Capital gain = $4,900,000
Tax on terminal return (~50% marginal, 50% inclusion) = ~$1,225,000
With an estate freeze (implemented 10 years earlier, business value = $2M):
Founder holds fixed preferred shares (frozen at $2M value)
Future growth ($3M) accrues to next generation's common shares
Founder's capital gain at death: on $2M freeze value, not $5M
Tax reduction: potentially $375,000+ saved
How an Estate Freeze Works
The most common estate freeze mechanism is a Section 86 or Section 85 share exchange under the Income Tax Act:
- The freeze: The business owner exchanges their common shares (which hold all the growth potential) for fixed-value preferred shares equal to the current FMV of the business. This exchange is done at "cost" — no capital gains triggered at the time of the freeze.
- New common shares issued: New common shares with nominal value are issued to the next generation (children, family trust, or both). These shares capture all future growth above the frozen value.
- Owner retains control: The preferred shares typically carry voting rights, allowing the owner to retain control of the business even after the freeze.
- Future growth taxed in next generation: As the business continues to grow, that growth is realized by the common shareholders — not by the original owner's estate.
Role of the Family Trust in an Estate Freeze
The new common shares are often issued to a discretionary family trust rather than directly to children. This provides several advantages:
- Income splitting: Trust income and capital gains can be allocated to low-income family members each year
- Flexibility: Beneficiaries don't need to be determined at the time of the freeze — can add grandchildren later
- Control: The trustee (typically the business owner or their spouse) continues to oversee distributions
- Lifetime capital gains exemption (LCGE) multiplication: If the trust distributes capital gains on a future sale to multiple beneficiaries, each may access their own $1.25M LCGE — multiplying the exemption across family members
LCGE multiplication example: A family trust with 4 adult beneficiary children distributes capital gains from a $5M business sale. Each child can claim their own $1.25M LCGE — sheltering up to $5M in gains from tax entirely. Without the trust structure, only the original owner's LCGE applies.
Types of Estate Freezes
| Type | Mechanism | Best For |
|---|
| Classic freeze (Section 86) | Share exchange within same company | Most private corporations |
| Section 85 rollover freeze | Transfer to new Holdco; receive preferred shares | More complex structures; adding Holdco layer |
| Partial freeze | Freeze only a portion of shares; retain some growth | Owner wants to retain upside on portion of business |
| Re-freeze | Second freeze after first freeze value has grown | When business value has grown significantly post-freeze |
Lifetime Capital Gains Exemption (LCGE)
The LCGE allows Canadian residents to shelter capital gains on Qualifying Small Business Corporation (QSBC) shares — approximately $1,250,000 per individual in 2024 (indexed annually). An estate freeze, combined with the LCGE, is among the most powerful tax strategies for business owners:
- Freeze locks in current value for the owner
- Future sale of new common shares (held by family trust beneficiaries) can each use their own LCGE
- Effective tax rate on business sale proceeds can be dramatically reduced
Non-Tax Benefits of an Estate Freeze
- Succession planning: Transfers economic interest to the next generation while maintaining management control
- Estate equalization: Can allocate business value among multiple children, including those not involved in the business
- Creditor protection: Assets held in a family trust have some creditor protection for beneficiaries
- Certainty of estate value: The owner's estate is capped at the freeze value — making estate planning more predictable
When to Consider an Estate Freeze
- Your business has grown significantly and will continue to grow
- You have family members (children, grandchildren) who could benefit from the future growth
- You're concerned about the capital gains tax your estate will owe at death
- You're beginning to think about business succession planning
- You want to multiply the LCGE across family members on a future business sale
Get professional advice: An estate freeze involves complex corporate reorganization, tax elections, and legal documentation. It must be done correctly to achieve the tax benefits and avoid triggering unintended consequences. Always work with an estate lawyer and tax accountant experienced in business succession planning.

Frequently Asked Questions
How much does an estate freeze cost?
Legal and accounting fees for a basic estate freeze typically range from $5,000 to $20,000+, depending on complexity. This is usually a one-time cost offset by potentially hundreds of thousands in future tax savings.
Can I undo an estate freeze?
An estate freeze is not easily reversed once completed. However, a "re-freeze" or "thaw" of certain provisions can be done. Get advice before proceeding — understand the long-term implications first.
Is an estate freeze only for large businesses?
No. Businesses worth $500,000+ can benefit, especially if significant future growth is expected. The LCGE multiplication strategy works with businesses of all sizes as long as shares qualify as QSBC shares.
