The Lifetime Capital Gains Exemption (LCGE) in Canada — How It Works

A Vancouver couple, both 62, run a successful engineering consultancy held inside a Canadian-controlled private corporation. A US-based competitor offers $4 million for the business in early 2026. If the couple each hold half the QSBC shares and each can claim the LCGE on their half, the federal taxable capital gain on the sale collapses from roughly $2 million to roughly $750,000 — a federal tax saving in the area of $300,000 at the top combined rate, plus comparable provincial relief. The same sale, structured with the couple holding shares jointly and selling through a single seller, sees half the LCGE permanently lost.

The LCGE is one of the few large tax provisions in the Canadian system where the structure of ownership before the disposition determines how much of the exemption gets used. Once the deal is signed, the LCGE that was available but unused is gone. For the broader picture of how this fits into business and family planning, see our pillar on estate planning in Canada and our companion guide on estate freeze.

What the LCGE actually does #

Section 110.6 of the Income Tax Act provides a "capital gains deduction" — the formal name in the legislation — that allows an eligible individual to deduct, against taxable income, an amount equal to half of certain capital gains realised on qualified property.^[1] Because Canada taxes 50 percent of capital gains (the inclusion rate the federal government proposed increasing in 2024, then deferred and ultimately cancelled rather than implementing), the practical effect is to fully exempt the gain itself up to the LCGE amount.

The LCGE was raised from approximately $1,016,836 to $1.25 million for dispositions on or after June 25, 2024, and was fixed at $1,250,000 for 2025 while that increase was phased in.^[4] Annual indexation of the LCGE resumed in 2026, taking the amount to approximately $1,275,000. Always confirm the current-year figure with the CRA before relying on an exact number, since the indexed amount moves every year.

The capital gains deduction itself, claimed at line 25400 of the T1, is half of the LCGE — roughly $637,500 on the 2026 amount — because of the 50 percent inclusion rate.^[2] Either way you describe it, the result is the same: up to the full LCGE amount of capital gain on qualifying property can pass through the tax system without being taxed federally.

The AMT changes effective 2024 increased the AMT exposure on large LCGE claims; for very large gains, the AMT calculation has become a meaningful planning consideration.

What counts as qualified property #

Three asset classes qualify. Each has its own technical test, but in summary:

Qualified Small Business Corporation (QSBC) shares. A QSBC share is a share of a Canadian-controlled private corporation that meets three structural tests at the time of sale:

1. The "all or substantially all" test — more than 90 percent of the corporation's assets are used in an active business carried on primarily in Canada (or are shares or debt of connected small business corporations that are themselves in active business).
2. The 24-month holding period — the shares have been owned by the individual or a related party for at least 24 months prior to disposition.
3. The "more than 50 percent" test — throughout the 24 months before disposition, more than 50 percent of the corporation's assets have been used in an active business.

Many Canadian operating companies meet these tests naturally. Many investment-heavy holding companies do not. A common problem: a successful small business retains profits inside the corporation rather than distributing them as dividends, and the accumulated investment portfolio pushes the company's asset mix past the 50 percent or 90 percent thresholds. The shares then fail the QSBC test, and the LCGE is unavailable. "Purification" transactions — moving investment assets out of the operating company into a sister holdco — restore QSBC status, but they must be completed well in advance of the sale.

Qualified farm property and qualified fishing property. Real property (or shares of a corporation holding such property, or an interest in a partnership) used by the individual, a spouse, or a child principally in the business of farming or fishing in Canada. The detailed test in section 110.6 is intricate; the farm or fishing operation must have been the principal user of the property over a defined holding period.

For the dispositions that occur on or after June 25, 2024, qualified farm and fishing property are eligible for the increased $1.25 million LCGE alongside QSBC shares.

The estate freeze and trust multiplication #

The LCGE is a per-individual exemption. A married couple with two adult children, each able to claim their own LCGE on a future business sale, can in principle shelter four times the individual LCGE amount — roughly $5 million of gain at current levels — on the same transaction. Getting there requires the family's ownership structure to put eligible QSBC shares in each individual's hands well before the sale.

The standard mechanism is the estate freeze with family trust.^[1] The founder exchanges their existing growth shares for fixed-value preferred shares (the "freeze"), and a new class of growth-bearing common shares is issued to a discretionary family trust that has the founder's spouse and adult children as beneficiaries. Future growth in the company's value accrues to the trust-held common shares.

When the company is later sold:

• The trustees of the family trust allocate the capital gain among the beneficiaries (subject to the trust deed and the trustees' fiduciary duties).
• Each beneficiary reports their allocated share of the gain on their own T1 return.
• Each beneficiary who is a Canadian resident can claim their own LCGE against their allocated gain.

The freeze must be done well before the sale (the 24-month QSBC holding period applies, and the freeze itself does not reset the clock). Many freeze-and-trust structures get unwound or amended for non-tax reasons before the sale, and the LCGE multiplication that looked tidy on a planning slide can be less tidy in practice.

The 21-year deemed disposition rule for personal trusts adds a constraint: the trust will be deemed to dispose of its assets at fair market value on the 21st anniversary of its creation, triggering tax in the trust unless the trustees roll out the assets to beneficiaries beforehand. Family trusts established for LCGE planning often wind down or distribute assets well before the 21-year mark.

At death — the deemed disposition and the LCGE #

Section 70 of the Income Tax Act treats death as a deemed disposition of all capital property at fair market value.^[5] For Canadians holding QSBC shares or qualified farm/fishing property at death, the deemed disposition can trigger a large capital gain on the final return.

The LCGE can be claimed on this deemed disposition, just as it would be on a sale during life — provided the shares still meet the QSBC test (or the farm/fishing property still meets its test) at the moment of death.

Three planning considerations:

1. A spousal rollover under section 70(6) defers the deemed disposition by transferring the shares to the surviving spouse at the deceased's adjusted cost base. The LCGE is not claimed at this point; the gain is deferred to the spouse's eventual disposition.
2. An election to opt out of the spousal rollover can be made on the final return, triggering the deemed disposition immediately and allowing the deceased's LCGE to be used. This is generally worthwhile only when the spouse would not otherwise be able to use the LCGE on a later sale, or when the deceased has unused LCGE room that would otherwise be lost.
3. The 36-month Graduated Rate Estate window allows the executor to time post-death dispositions to optimise tax outcomes. Coordinating these elections with the LCGE is high-value planning work and typically requires both tax-and-estate advisor input.

What can go wrong #

Five patterns recur in LCGE planning failures:

• The QSBC test fails because of asset mix. Accumulated investment assets push the company past the 50 percent or 90 percent thresholds. Purification was never done.
• The 24-month holding period is missed. Shares were issued or transferred too recently.
• The freeze was done but the trust never made the right elections. The shares end up with the wrong attribution.
• The AMT bite was overlooked. A large LCGE claim triggers significant AMT, partly recoverable over the following seven years but a real cash-flow cost.
• The CRA reassesses the QSBC status. Documentation of asset use, active business activity, and ownership history is critical; CRA challenges to LCGE claims are common at the higher dollar levels.

What we focus on at It's Simple Will #

The LCGE is firmly in advisor territory — the structures (estate freeze, family trust) and the technical tests (QSBC, qualified farm property) generally require both a tax accountant and a corporate lawyer to set up and maintain. The Will Creator handles the personal will and powers of attorney; for clients with operating businesses or farm/fishing property, the will references the corporate structure that the family's tax and corporate advisors have built around it. The Life Discovery Kit captures contact information for those advisors so the executor knows whom to call. Our companion piece on estate freeze walks the freeze mechanic in more detail.
