Construction Company Owner in Alberta with a $5M Sale: LCGE Plus Spousal Trust Multiplication in 2026

The Scenario: $5M Calgary Construction Company, One Owner, a Spouse, and Two Adult Children

Dave Makovec, 57, built a Calgary-based commercial construction company over 25 years. The corporation holds heavy equipment, a yard lease, and $5M in enterprise value — almost entirely in active-business assets. A national general contractor wants to acquire Dave's shares for $5,000,000. Dave's adjusted cost base on the shares is the nominal $100 he subscribed at incorporation. His wife Karen has no direct shareholding. Their two adult children, ages 28 and 31, have both worked in the business for over five years.

Without any multiplication strategy, Dave claims his $1,250,000 LCGE on the $5,000,000 gain, and the remaining $3,750,000 flows through the two-tier capital gains inclusion at Alberta's 48% top combined rate. The result: approximately $1,180,000 in federal-plus-provincial tax. That is 23.6% of the sale price — gone before legal and advisory fees.

The question: could Dave have structured his shareholdings to multiply the LCGE across Karen and his children, sheltering $2,500,000 to $3,750,000 instead of $1,250,000?

The Math: One LCGE vs Two vs Three on a $5M Gain

The 2026 LCGE for Qualified Small Business Corporation shares is $1,250,000 per individual — a lifetime limit tracked by CRA via Form T657. Each eligible individual who holds qualifying shares (directly or as a trust beneficiary) can claim their own exemption independently.

The gap between one LCGE and three LCGEs is approximately $800,000 in tax. On a $5M deal, that is the difference between keeping $3.82M after tax and keeping $4.62M. The structure that produces three LCGEs requires a family trust that has held qualifying shares for at least 24 months — and that trust must have been set up years before the sale was contemplated.

How the Family Trust Creates Multiple LCGEs

The standard LCGE multiplication structure works through an estate freeze combined with a discretionary family trust. Here is how it would have worked for Dave if implemented five years ago when the construction company was worth $2M:

1. Estate freeze (Section 86 share exchange): Dave exchanges his common shares for fixed-value preferred shares worth $2M. The preferred shares lock in Dave's current value and entitle him to a fixed redemption amount.
2. New growth shares issued to family trust: The corporation issues new common shares to a discretionary family trust for nominal consideration ($100). Karen and the two adult children are named as beneficiaries of the trust.
3. Future appreciation accrues to the trust: Over the next five years, the company grows from $2M to $5M. The $3M of new value accrues to the common shares held by the trust — not to Dave's frozen preferred shares.
4. On sale, the trust allocates the gain: The trust sells the common shares and allocates the $3M capital gain among the beneficiaries. Each beneficiary claims their own $1,250,000 LCGE on their allocated portion.
5. Dave claims his LCGE on the preferred shares: Dave's preferred shares are redeemed or sold for $2M. He claims his $1,250,000 LCGE on the gain, leaving $750,000 taxable.

Net result: Dave uses his LCGE on $1,250,000, Karen uses hers on up to $1,250,000 of the trust-allocated gain, and the adult children each use theirs on their portions. Up to four LCGEs — $5,000,000 sheltered — on a $5M deal. In practice, the full $5M shelter requires that all four family members have never claimed any prior LCGE and that the trust allocation and QSBC tests are satisfied for each.

The Attribution Rules: Why You Cannot Simply Gift Shares to a Spouse

The most common mistake in LCGE multiplication is the simplest one: Dave transfers common shares to Karen for $1, expecting her to claim the LCGE on her portion of the gain when the business is sold. Sections 74.1 and 74.2 of the Income Tax Act kill this approach. When property is transferred to a spouse for less than fair market value, any income or capital gain on that property is attributed back to the transferor — Dave — for tax purposes. Karen's LCGE claim fails because the gain is not hers in CRA's eyes.

There are three ways to avoid spousal attribution:

1. Spouse pays fair market value from their own funds

Karen buys shares directly from Dave or subscribes for new shares at fair market value, using her own money — not funds loaned by Dave. On a $5M company, this means Karen needs substantial independent capital to acquire a meaningful shareholding. For most construction company families, this is impractical.

2. Estate freeze with trust structure

The estate freeze described above avoids the attribution problem because the new common shares are issued to the family trust for nominal consideration ($100) at a time when they genuinely have nominal value. The future appreciation accrues to the trust's shares without attribution to Dave, because the growth is not a transfer from Dave — it is organic appreciation on shares the trust acquired independently. The Section 74.5 exception for transfers at fair market value is satisfied because the shares were worth $100 when issued.

3. Prescribed-rate loan to a spousal trust

Dave lends funds to a spousal trust at the CRA's prescribed rate (currently 4%), and the trust uses the funds to subscribe for shares. As long as the trust pays the prescribed interest by January 30 of each year, attribution does not apply. The downside: the trust must earn a return exceeding the prescribed rate to produce a net benefit, and the annual interest obligation is real.

The 21-Year Deemed Disposition: The Trust's Ticking Clock

Under Section 104(4) of the Income Tax Act, every trust faces a deemed disposition of all its capital property at fair market value on the 21st anniversary of its creation. The trust is deemed to have sold everything and reacquired it — triggering capital gains tax on any unrealized appreciation, even though no actual sale occurred.

For family trusts holding construction company shares, this creates a hard planning horizon. A trust created in 2005 faces its deemed disposition in 2026. A trust created in 2015 has until 2036. The options before the 21-year mark:

• Sell the business before the anniversary — the most common approach, and exactly what Dave is doing. The gain is realized on an actual sale, allocated to beneficiaries, and sheltered by their individual LCGEs.
• Roll shares out to individual beneficiaries under Section 107(2) — this distributes the shares from the trust to individual beneficiaries on a tax-deferred basis. The beneficiaries then hold the shares personally and can claim their own LCGEs on a future sale. The rollout must happen before the 21-year anniversary to avoid the deemed disposition inside the trust.
• Pay the tax inside the trust — trusts pay capital gains tax at the 66.67% inclusion rate on all gains, with no access to the $250,000 threshold at 50% that individuals enjoy. At Alberta's trust tax rates, this is the most expensive option and defeats the purpose of the multiplication strategy.

TOSI Guardrails: When the Top Rate Applies to Family Members

The Tax on Split Income rules under Section 120.4 were introduced in 2018 to prevent income splitting through private corporations. TOSI imposes the top marginal rate — 48% in Alberta — on certain income received by family members who are not sufficiently involved in the business.

For LCGE multiplication, the key carve-out is this: TOSI does not apply to capital gains that are eligible for the Lifetime Capital Gains Exemption. If the shares qualify as QSBC shares and the beneficiary's allocated gain is within their available LCGE room, TOSI does not bite. Karen and the adult children can claim their LCGEs without TOSI interference.

The risk emerges when allocated gains exceed the LCGE. If the trust allocates $1,500,000 of gain to Karen and she has $1,250,000 of LCGE room, the $250,000 excess is subject to TOSI at the top rate — unless Karen qualifies for the excluded-business exception. For Dave's adult children who have worked in the construction company on a regular and continuous basis, the excluded-business exception under Section 120.4(1) applies and TOSI does not apply to any of their gain, even above the LCGE.

Karen, who has not worked in the business, does not meet the excluded-business exception. Her gain above the LCGE is subject to TOSI. The planning response: allocate no more than $1,250,000 of gain to Karen (matching her LCGE exactly), and allocate any excess to the adult children whose excluded-business status protects them.

The Purification Problem: Construction Companies and Passive Assets

Construction companies accumulate cash between projects. A $5M company might have $800,000 in retained earnings sitting in a high-interest savings account or GICs at any given time — and that passive asset buildup can disqualify the shares from QSBC status.

The 90% active-business test at the time of sale means no more than $500,000 of a $5M company's assets can be passive. The 50% test for the 24 months prior is more forgiving in percentage terms but punishing in its look-back window — if the company held $2.6M in passive assets at any point during the prior 24 months (breaking the 50% threshold on a $5M company), the QSBC tests fail.

For construction businesses, purification typically means:

• Paying out excess cash as dividends to the owner (triggering personal tax on the dividend, but preserving QSBC status for the much larger LCGE benefit)
• Moving passive investments to a separate holding company via a Section 85 rollover — the holdco holds the investments, the operating company stays clean
• Investing excess cash in active-business assets — equipment purchases, leasehold improvements, or prepaid expenses that qualify as active-business use

Dave's $5M company needs continuous purification monitoring. A single quarter where retained cash pushes passive assets above $2.5M (50% of total value) during the 24-month look-back can disqualify every family member's LCGE claim — costing the family up to $800,000 in lost tax savings.

Timing the Structure: The 3-to-5-Year Planning Window

LCGE multiplication is not a closing-day strategy. The minimum viable timeline:

For Dave, the planning window needed to open in 2021 or 2022 for a 2026 sale. If he did not implement the freeze and trust structure back then, the multiplication opportunity is largely gone. He is left with his single $1,250,000 LCGE and a $1,180,000 tax bill. The lesson applies to every construction company owner who thinks a sale is 3 to 5 years away: the trust structure decision is today's decision, not the year-of-sale decision.

What Dave Should Have Done — and What You Can Still Do

If Dave implemented the freeze and trust in 2021 when the company was worth $3M:

• Dave's preferred shares: $3M value, with $1,250,000 sheltered by his LCGE, $1,750,000 taxable
• Trust common shares: $2M of growth (the $5M sale price minus $3M freeze value)
• Trust allocates $1,250,000 to Karen (fully sheltered by her LCGE) and $750,000 to an adult child (fully sheltered by their LCGE)
• Total LCGEs used: $3,250,000. Total taxable gain: $1,750,000
• Tax at Alberta's 48% rate on $1,750,000 of gain: approximately $545,000
• Savings versus one LCGE: approximately $635,000

For Alberta construction company owners who have not yet started exit planning, the action items are immediate:

1. Get a QSBC eligibility audit — review the balance sheet for passive assets, confirm the 90% and 50% active-business tests are currently met, and identify anything that needs purification
2. Implement the estate freeze and family trust now — the 24-month clock starts the day the trust acquires shares, and GAAR comfort grows with every year of genuine trust operation
3. Set up continuous purification monitoring — quarterly reviews of the corporation's passive-to-active asset ratio, with excess cash paid out or moved to a sister holdco before it accumulates
4. Coordinate with your spouse and adult children — confirm that no family member has used prior LCGE room on other dispositions, and ensure adult children who will be trust beneficiaries are genuinely involved in the business for TOSI excluded-business status

The difference between a single LCGE and a multiplied LCGE on a $5M Alberta construction company sale is $420,000 to $800,000 in tax savings. That gap is larger than many people's annual income — and it is entirely determined by whether the trust structure existed 24 months before the buyer arrived.
