Anonymised, illustrative composite. A father transferred landscaping-company shares to his adult daughter at an independent valuation of $2.10 a share. Three years later, CRA reassessed the fair market value at $2.90 — and taxed the gap to both of them.
At a glance
A father was transferring his landscaping company to his daughter, who had run day-to-day operations for six years and was ready to take over ownership. To keep the transfer defensible, he commissioned an independent business valuation, which came back at $2.10 a share. Shares changed hands at that price, funded by a promissory note from the daughter back to the father, and both returns were filed on that basis.
Three years later, CRA opened an audit — unrelated in origin, triggered by an unrelated matter in the daughter's now-larger business — and its own valuator reviewed the original transfer as part of the file. CRA's position was that the original valuation had understated normalized earnings by excluding a one-time equipment writedown that should have been added back, and that fair market value at the transfer date was actually $2.90 a share. The Agency reassessed on that basis.
Neither side disputed that the CRA figure was defensible — the equipment writedown genuinely was non-recurring, and add-backs for non-recurring items are standard valuation practice the original report had simply missed. The dispute was entirely about what the reassessment did to two different taxpayers on the same transaction.
100,000 shares. Original price: $2.10 — $210,000. CRA fair market value: $2.90 — $290,000. The $80,000 difference (100,000 shares × $0.80) is the amount that ended up taxed twice across father and daughter, for reasons that turn entirely on which side of s.69(1) each of them sits.
s.69(1)(b) reaches a disposition to a non-arm's-length person for less than fair market value and deems the transferor to have received proceeds equal to that fair market value: “the taxpayer shall be deemed to have received proceeds of disposition therefor equal to that fair market value.” Applied here, the father is deemed to have received $290,000 for shares he actually sold for $210,000 — an extra $80,000 of capital gain reported on money that never reached him.
That is only half the section, and it is the asymmetric half that does the damage. s.69(1)(a) caps an acquirer's cost at fair market value where the acquirer paid more than fair market value — the mirror case, not this one. There is no paragraph in s.69(1) that raises a non-arm's-length purchaser's cost up to fair market value where she paid less than fair market value for something other than a gift. The daughter did not acquire the shares as a gift; she paid $210,000 for them, under a promissory note, on commercial (if non-arm's-length) terms. So her adjusted cost base under the ordinary rules stays at $210,000 — what she actually paid — even though her father is now taxed as if he had sold at $290,000.
The consequence is the well-known double-tax trap in non-arm's-length transfers: the same $80,000 of appreciation is taxed once to the father, on the CRA-determined gain he never received in cash, and taxed again to the daughter, whenever she eventually disposes of the shares, because her cost base never moved to reflect the value CRA had already assessed her father on.
The standard protection is a price adjustment clause — a term in the transfer agreement stating that if a taxing authority or a court establishes a fair market value different from the price used, the price is automatically restated to match, with the difference repaid or the note adjusted. CRA has historically accepted such clauses administratively where the parties intended a genuine arm's-length-equivalent price and took reasonable steps to establish one, though that is a matter of assessing practice rather than anything written into the Act itself. No such clause was in this transfer agreement, so there was nothing to invoke when the number moved.
The father's return was reassessed within CRA's normal reassessment period, adding tax on the extra $80,000 of deemed proceeds. The daughter's cost base was not adjusted upward — CRA had no basis to do so, and none was argued, because s.69(1) simply does not provide for it on these facts. The family funded the additional tax from other assets rather than litigating a valuation dispute over what was, in the end, a defensible add-back CRA's own auditor could support.
Going forward, the family's advisor added a price adjustment clause to every intergenerational transfer agreement the practice now drafts, specifically because this file showed what happens without one.
Had the gap between the two valuations been larger — a genuinely disputed methodology rather than a missed add-back both sides ultimately agreed was correct — the family would have faced the same double taxation with no realistic way to unwind it after the fact. A price adjustment clause has to exist before the CRA moves the number; it cannot be added retroactively once a reassessment has already fixed the transferor's proceeds under s.69(1)(b).
The tell was in the valuation report itself, not in anything the family did wrong: a one-time equipment writedown sitting in the trailing financials, never flagged for an add-back. Nobody read the report looking for CRA's future objection — they read it for a defensible number at the time. A defensible number and a permanent one are not always the same thing on a related-party transfer, which is exactly why the fix is contractual, not just diligent.
