Nothing in the qualifying tests asks what the share certificate says. They ask three narrow, factual questions about the corporation itself — and a passive investment portfolio sitting inside it can quietly fail the deal.
Key takeaways
STEP 01 OF 10
The lifetime capital gains exemption under ITA s. 110.6 shelters up to $625,000 of taxable capital gain on a disposition of qualified small business corporation shares — but only shares that actually meet the definition qualify. Nothing about a share’s label, class or the fact that a lawyer called it a "qualifying share" in a closing document makes it qualify; the definition is a specific, three-part factual test applied to the corporation and the ownership history, not to the paperwork.
Run this test before pricing a deal around LCGE eligibility, not after — a share that fails the test shelters nothing, however confidently the parties assumed otherwise.
STEP 02 OF 10
At the determination time — ordinarily the moment of disposition — the share must be a share of the capital stock of a small business corporation, owned by the individual claiming the exemption (ITA s. 110.6(1), paragraph (a), same source above). This is the most straightforward of the three tests: it asks a simple question about present ownership and present corporate status.
Where the exemption is being claimed by more than one family member off a single underlying corporation — the multiplication strategy covered in setting up an estate freeze before a transfer — this test is applied separately to each individual’s own shares, not once to the corporation as a whole.
STEP 03 OF 10
Throughout the 24 months immediately preceding the determination time, the share "was not owned by anyone other than the individual or a person or partnership related to the individual" (ITA s. 110.6(1), paragraph (b), same source above). A share recently acquired from an unrelated party — through a purchase, an unrelated estate, or a non-family reorganization — can fail this test even where the corporation itself has operated for decades.
This test looks at the specific share’s ownership chain, not at how long the business has existed. A newly issued share — from a freeze, for example — inherits its predecessor share’s qualifying history only through the specific rollover and continuity rules that apply to that transaction; confirm the mechanics with the corporation’s tax advisor rather than assuming continuity.
STEP 04 OF 10
Throughout the part of that same 24 months while the share was owned by the individual or a related person, the corporation had to be a Canadian-controlled private corporation, "more than 50% of the fair market value of the assets of which was attributable to" assets used principally in an active business (ITA s. 110.6(1), paragraph (c), same source above). This is a rolling, fact-based test applied to the corporation’s actual balance sheet composition throughout the period — not a snapshot taken once.
A corporation that dips below the 50% threshold at any point during the relevant 24-month window — because a redundant cash or investment position grew too large relative to its active-business assets — can fail this test even if it comfortably clears it both before and after that dip.
STEP 05 OF 10
A further layer applies through the underlying definition of "small business corporation" itself, referenced by Test 1: a small business corporation is a Canadian-controlled private corporation where all or substantially all of the fair market value of its assets is used principally in an active business carried on primarily in Canada. That is the Act’s own phrase — "all or substantially all" — and it is not a defined percentage anywhere in the statute.
Do not attach a specific number to that phrase in a client conversation or a closing document. A common rule of thumb treats a very high proportion — comfortably above 90% — as generally satisfying it, but that is professional judgment applied to the statutory words, not a published statutory threshold. Treat any number quoted against "all or substantially all" as advisory shorthand, never as the test itself.
STEP 06 OF 10
Take a corporation with $2,000,000 of total assets at the determination time, of which $1,850,000 — 92.5% — is used in the active business, with the remainder sitting in a redundant investment account. That proportion is high enough to make a strong case for satisfying the "all or substantially all" standard from Step 5, though the Act does not convert the phrase into a bright-line percentage.
Now look at the rolling 24-month test from Step 4 on the same corporation at an earlier point: assets of $1,200,000 with $700,000 — 58.3% — in active use passes the "more than 50%" threshold comfortably. But if the corporation had instead built up its redundant cash position to $800,000 against the same $700,000 of active assets — a $1,500,000 total — the active-business proportion falls to 46.7%, and Test 3 fails for that period. The same corporation, the same active business, a different balance-sheet decision, and a materially different tax outcome.
STEP 07 OF 10
A corporation that has drifted below the thresholds in Steps 4 or 5 — usually because retained earnings accumulated in redundant investments rather than being distributed or redeployed into the active business — can often be brought back into compliance through a purification transaction: distributing or transferring the redundant assets out of the corporation before the determination time, so the active-business proportion recovers.
This has to happen with enough lead time that the corrected asset mix is actually in place throughout the relevant 24-month window, not just on closing day — a purification completed the week before a sale does not retroactively fix an asset mix that failed the test six months earlier.
STEP 08 OF 10
A common misconception is that preferred shares, especially those created in an estate freeze, are somehow less likely to qualify than common shares. Ontario legal commentary states the point directly: "the exemption attaches to the individual who owns qualifying shares and realizes the gain, not to a particular certificate design," and "nothing in the qualifying tests asks whether the shares carry a fixed redemption value, a dividend preference, or voting rights — those are contractual features of the share, not a bar to eligibility on their own" (treadstonelaw.ca).
What actually decides eligibility, per that same commentary, is whether the corporation is a CCPC, whether "a sufficiently high proportion of the corporation’s assets are used in an active business carried on in Canada," and whether "the shares have been held, and the corporation’s assets have been used the right way, throughout a required period leading up to the sale" — precisely the three tests in Steps 1 through 4 of this guide, restated in plain language.
STEP 09 OF 10
Where an individual seller does not personally meet the qualifying-share tests — or where the buyer is an employee group rather than a family member — a structurally different exemption exists for a sale to an employee ownership trust, sheltering up to $10,000,000 of capital gain shared across eligible individuals, for a disposition after 2023 and before 2027, under ITA s. 110.61. Its own conditions are separate from, and in some respects stricter than, the s. 110.6 tests in this guide, including a 24-month ownership test of its own and a joint election requirement.
Do not treat the two exemptions as interchangeable or assume meeting one automatically satisfies the other — each has its own definitions, and the EOT route in particular carries governance and trustee-composition requirements that have no equivalent in an ordinary s. 110.6 disposition.
STEP 10 OF 10
Every test in this guide is easiest to satisfy when it is checked years before a sale, not weeks before one — the 24-month ownership and asset tests in particular cannot be fixed retroactively once the determination time has passed. A seller planning an eventual exit should have their tax advisor confirm qualifying-share status, and address any purification needed, as a standing item well ahead of any live transaction, in the same way planning the tax on a Canadian business exit treats the broader exit sequence.
A buyer relying on a seller’s LCGE eligibility to justify a share-sale structure should ask for evidence of this check, not just a representation in the purchase agreement — a broken qualifying-share test surfaces as the seller’s tax problem, but a poorly diligenced one can still complicate or delay a closing.
The pattern in Step 6 repeats across a large share of qualification failures this guide is written to prevent: a genuinely active, operating business accumulates cash or investments faster than it redeploys them, and the balance sheet slowly drifts toward the point where the active-business-asset tests no longer pass. Nothing about the business itself changed — only its capital allocation did.
This is exactly why the asset tests are worth checking on a rolling basis rather than once, years before any sale is contemplated, and why a corporation approaching a sale should have its balance sheet reviewed against these specific tests well ahead of a transaction, not discovered as a problem during due diligence.
It can — the test looks at the specific share's ownership history, and a newly issued share generally starts its own 24-month clock unless a specific rollover or continuity rule preserves the predecessor share's history. Confirm the mechanics for any reorganization with a tax advisor before assuming continuity.
No — the Act uses that phrase without defining a specific number. Professional practice generally treats a very high proportion, comfortably above the informal benchmarks some advisors use, as satisfying it, but this is judgment applied to statutory language, not a published threshold.
Only if there is enough lead time left in the relevant 24-month window for the corrected asset mix to actually have been in place throughout the period the test examines. A purification completed after the determination time, or too close to it, does not retroactively cure an earlier failure.
Yes — the qualifying tests examine the corporation's status and the ownership history of the specific shares, not the class, voting rights or dividend preferences those shares carry.
