Estate Freeze
A tax planning technique that freezes the value of an owner's shares at their current value and transfers future growth to the next generation or to a family trust, allowing the capital gain to be crystallized at a chosen moment.
Definition
An estate freeze is a corporate reorganization through which a business owner exchanges their common shares (whose value grows over time) for preferred shares with a fixed value.
In French-language Quebec documentation, you’ll see gel successoral used for the same concept.
New common shares — the ones that will capture all future growth — are issued to family members, a family trust, or the next generation. Net effect: the value of the business owned by the founder is “frozen” as of the day of the transaction.
This technique is specifically governed by Section 86 (share exchange) or Section 85 (rollover) of the Income Tax Act. It’s common in the estate planning of Quebec and Canadian SMEs.
Why an estate freeze matters in a business sale
For an owner considering a sale within a two-to-five-year horizon, an estate freeze serves two complementary goals. First, it crystallizes the capital gain at the current value of the business.
If your corporation is worth $3 million today and you carry out a freeze, your taxable gain will be calculated on that value, regardless of whether the business ends up being worth $4 or $5 million at the time of sale. The additional growth will go to the new shareholders (often a family trust), each of whom can use their own Lifetime Capital Gains Exemption.
Second, the freeze lets you plan the wealth transfer in an orderly way. In a family succession context, it eases the transition without the founder losing control — the preferred shares received in exchange generally carry voting rights and a priority redemption right.
The timing is critical. A freeze carried out a few months before a third-party sale risks being challenged by the CRA as a tax avoidance scheme.
Canadian courts have established that these structures must have real economic substance and be put in place within the context of legitimate planning.
What every seller should know
- An estate freeze should ideally be carried out two to five years before the planned sale. The older the structure, the more credible it is in the eyes of the tax authorities.
- The operation requires a formal valuation of the business at the time of the freeze to establish the redemption value of the preferred shares. That valuation has to be defensible.
- The freeze can be combined with a family trust to multiply the Lifetime Capital Gains Exemption — each eligible beneficiary being entitled to their own exemption (~$1,250,000).
- A freeze is reversible (“thawing”) if circumstances change, but that operation itself has tax consequences. It’s better to plan carefully from the start.
