Deemed Dispositions
CRA doesn't wait for you to sell. Certain events trigger an automatic "sale" of your assets at fair market value — and the tax bill that comes with it.
What triggers a deemed disposition
Under the Income Tax Act, Canada treats certain life events as if you sold all of your capital property at fair market value — even though no actual sale occurred. The resulting capital gain is taxable, and the liability falls due regardless of whether there's cash available to pay it.
Death
All capital property is deemed disposed of at FMV immediately before death. This is the most common and significant trigger for business owners.
Emigration
Leaving Canada triggers a departure tax — a deemed disposition of most property at FMV on the date of departure.
Trust distributions
The 21-year rule deems a trust to have disposed of its capital property at FMV, creating a taxable event even if nothing is distributed.
The deemed disposition on death
For business owners, the deemed disposition at death is often the single largest tax event the estate will face. If you hold shares in a private corporation worth several million dollars, the deemed sale generates a capital gain that results in a tax bill in the hundreds of thousands or more — due immediately, whether or not there's cash to pay it.
Example: An owner holds shares with an adjusted cost base of $100,000 in a company now worth $5M. On death, CRA deems those shares sold at $5M, creating a $4.9M capital gain. At a 50% inclusion rate, $2.45M is added to the final tax return — resulting in a tax bill of roughly $1.3M at the top marginal rate. And the estate may have no liquid assets to pay it.
The challenge is compounded by the double tax problem: without planning, the same corporate value can be taxed twice — once at the shareholder level (deemed disposition) and again when the corporation distributes remaining value to the estate. Post-mortem planning strategies (pipeline transactions, the 164(6) election) exist specifically to address this, but they must be structured carefully and promptly after death.
Planning ahead for deemed dispositions
The tax triggered by a deemed disposition can be reduced, deferred, or funded — but only if the planning is done in advance. These are the most common strategies.
Estate freezes
The most direct way to limit the deemed disposition on death is to freeze the value of your shares at today's level. Future growth accrues to the next generation's shares, reducing the capital gain that will eventually be triggered by your death.
LCGE crystallization
If you haven't used your Lifetime Capital Gains Exemption (~$1,275,000 for 2026, indexed annually), crystallizing it before death means a portion of the deemed disposition is sheltered from tax. This planning is most effective when done well in advance.
Life insurance
Corporate-owned life insurance can fund the tax liability created by the deemed disposition, using the capital dividend account to deliver proceeds tax-free to the estate. The insurance must be properly structured and in place before it's needed.
Spousal rollover
Property left to a spouse or common-law partner can roll over at the deceased's tax cost, deferring the deemed disposition until the surviving spouse's death or disposition. This defers the problem rather than solving it, but can be a useful component of a broader plan.
Emigration and departure tax
Business owners who leave Canada face an immediate deemed disposition of most capital property. This includes shares in private corporations, regardless of whether the corporation itself remains in Canada. The departure tax can be substantial and must be planned for well in advance of the move.
Certain property is exempt from the departure tax — including Canadian real property, pension rights, and RRSPs. For everything else, the gain is crystallized at the date of departure. Under section 220(4.5), taxpayers can post acceptable security with CRA to defer the actual payment, but the gain itself is locked in. Post-departure planning options are limited, which makes pre-departure structuring essential.
The 21-year trust rule
Family trusts — commonly used in estate freezes and succession plans — face a deemed disposition of their assets every 21 years from the date the trust was created. For trusts holding private company shares, this can create an unexpected and significant tax liability if not planned for in advance.
Strategies include distributing trust property to beneficiaries before the 21-year anniversary (triggering a tax-deferred rollover), implementing a secondary estate freeze within the trust structure, or winding up the trust entirely. The key is to start planning several years before the anniversary — not months.
The role of valuation
Every deemed disposition is measured at fair market value — which means every planning strategy depends on knowing what the business is actually worth. We provide the independent, CBV-prepared business valuations that set the foundation for deemed disposition planning, whether you're freezing today or your estate is dealing with the consequences after death.
