An estate freeze is one of the most powerful succession and estate planning tools available to Canadian business owners. The fundamental goal is to crystallize — or freeze — the current value of a growing business in the hands of the owner, and transfer all future growth to the next generation, employees, or a family trust. When done correctly, an estate freeze limits the capital gain that will arise on the owner's death, multiplies access to the lifetime capital gains exemption, and enables income splitting with adult family members who participate in the business.
What Is an Estate Freeze?
In its simplest form, an estate freeze involves a share reorganization of a private corporation under ITA section 86 (or a transfer under ITA section 85). The business owner exchanges their common shares (which participate in future growth) for preferred shares whose value is fixed at the current fair market value of the business on the day of the freeze. New common shares — worth little or nothing at the time of the freeze — are then issued to the next generation or to a family trust.
As the business grows after the freeze, all the growth accrues to the new common shares. The owner's preferred shares remain fixed in value. On the owner's death, the deemed disposition triggers a capital gain only on the preferred shares — a gain that has been frozen at the current value. The post-freeze growth is taxed in the next generation's hands (or the family trust), at potentially lower tax rates and with access to each family member's own LCGE.
How an ITA Section 86 Freeze Works
A classic s.86 freeze (also called an "internal freeze") involves these steps:
- Valuation: Obtain a professional business valuation of the corporation's current fair market value
- Share reorganization: The corporation amends its articles to create a new class of fixed-value preferred shares
- Share exchange: The owner exchanges their common shares for the new preferred shares, with a redemption value equal to the current FMV of the corporation
- New common shares: New common shares (with a nominal value and nominal paid-up capital) are issued to the next generation, a spouse, or a family trust
- Rollover: The s.86 exchange is done on a tax-deferred rollover basis — no immediate capital gain is triggered
After the freeze, the owner holds preferred shares worth $X (the frozen amount) and the new common shares held by family members or the trust are worth essentially nothing today but will appreciate as the business grows.
The Family Trust in an Estate Freeze
Rather than issuing new common shares directly to family members, many freezes use a family discretionary trust as the holder of the new common shares. The trust structure offers several advantages:
- Flexibility: A discretionary trust allows the trustee to allocate income and capital gains among beneficiaries (who can include the owner's spouse, children, and even the owner themselves) in the most tax-efficient way each year
- LCGE multiplication: Multiple individual beneficiaries can each use their own $1.25M LCGE when the business is eventually sold or the shares are distributed
- Control: The business owner can serve as trustee and retain control over distributions while the next generation benefits economically
- TOSI caution: Post-2018 TOSI rules significantly restrict income splitting with adult beneficiaries who are not actively and meaningfully contributing to the business. Careful structuring is required
Tax Consequences of the Freeze
A properly structured estate freeze under s.86 is a tax-deferred event — no immediate tax is triggered. However, several tax attributes must be managed:
- Paid-up capital (PUC): The PUC of the new preferred shares must be set carefully. If PUC exceeds the ACB of the exchanged common shares, a deemed dividend arises under ITA s.84(3). Typically, the PUC is set equal to the ACB of the common shares surrendered, avoiding this problem.
- Stop-loss rules: If the preferred shares are later redeemed at less than their redemption value, a capital loss may arise — but anti-avoidance rules in ITA s.40(3.6) and s.112(3) must be considered
- Section 74.4 attribution: Transferring growth to a corporation where a spouse or minor child holds shares can trigger attribution under ITA s.74.4. Proper structuring avoids this
When to Do an Estate Freeze
The optimal time for an estate freeze is when the business is valuable but still growing — early enough that the post-freeze growth potential is meaningful for the next generation, but not so early that the business has minimal value and a freeze provides little benefit. Key triggers include:
- The owner is beginning to think about succession or retirement (typically in their 40s to 60s)
- The business has accumulated significant value (typically $500,000 or more, where a freeze meaningfully shelters future growth)
- Adult children are becoming involved in the business and could benefit from owning growth shares
- The owner wants to multiply access to the LCGE for a planned future sale
The Re-Freeze: Adjusting for New Growth
If the business grows substantially after an initial freeze, a re-freeze can be implemented. The owner exchanges their existing preferred shares (which have not grown in value) for new preferred shares reflecting the updated (higher) frozen value. This re-establishes the freeze at the new FMV and shifts further growth to the common shareholders. Re-freezes can be done multiple times as the business grows.

Frequently Asked Questions
Does an estate freeze trigger immediate tax?
No — a properly structured estate freeze under ITA s.86 is a tax-deferred rollover. No capital gain arises at the time of the exchange. The owner continues to hold shares in the corporation (now preferred shares) and the tax on the frozen gain is deferred until the preferred shares are redeemed or sold, or until the owner's death.
What happens to the estate freeze on the owner's death?
On death, the owner is deemed to have disposed of their preferred shares at fair market value (generally their redemption value — the frozen amount). A capital gain arises to the extent the redemption value exceeds the ACB. The owner's estate can use the lifetime capital gains exemption (if the shares are QSBC shares) to shelter up to $1.25M of this gain. Post-freeze growth — which resides in the common shares — is taxed in the hands of the next generation or trust, not the estate.
Can a freeze help multiply the lifetime capital gains exemption?
Yes — this is one of the primary planning benefits. By placing new common shares in the hands of multiple family members (directly or through a family trust), each individual shareholder can access their own $1.25M LCGE when the business is eventually sold or the shares distributed. A couple with two adult children could potentially shelter up to $5M in gains from tax, subject to QSBC qualification and TOSI rules.
Do I need a business valuation for an estate freeze?
A professional business valuation is strongly recommended and usually required. The freeze preferred shares must be set at the current FMV of the corporation — if the value is understated, CRA can challenge the freeze and deem additional income. A credible, documented valuation protects against CRA challenges and is essential if the freeze involves related-party transactions that could attract GAAR scrutiny.
