A vendor asked to roll part of the sale price into equity of the buyer's acquisition vehicle is being asked to become a minority shareholder in someone else's company. The tax deferral on that rollover is well established in Canadian law. The governance protections that make the resulting minority position tolerable are not automatic at all — they have to be negotiated.
Key takeaways
“Rollover equity” is a term borrowed from American buyout practice, and using it in a Canadian deal without translating it can obscure what is actually happening: a vendor is deferring tax on part of the sale price under a specific Income Tax Act election, and becoming a minority shareholder in the buyer's acquisition vehicle under the ordinary rules of Canadian corporate law. Both halves have real, sourced mechanics, and a vendor should negotiate around both, not just the tax half.
Subsection 85(1) of the Income Tax Act is the Canadian mechanism behind a rollover, and it applies where a taxpayer disposes of eligible property to a taxable Canadian corporation for consideration that “includes shares” of that corporation, with the parties jointly electing in prescribed form. The elected amount becomes both the deemed proceeds of disposition and the deemed cost of the shares received, but three limits matter to a rolling vendor specifically: the elected amount is bumped up to the fair market value of any non-share consideration — the “boot” — received alongside the shares, so cash paid as part of the same deal is taxed immediately regardless of the election; the elected amount cannot exceed the property's fair market value; and for inventory or non-depreciable capital property, it cannot go below the lesser of fair market value and cost amount. In practice, a vendor rolling $1.2 million of a $4 million sale into shares of the buyer's Newco is only deferring tax on that $1.2 million — the $2.8 million cash portion is taxed at closing whether or not the rollover election is made.
Once the shares are issued, the vendor's protection as a minority holder in the buyer's vehicle depends on Canadian corporate law's unanimous shareholder agreement mechanism, not on the rollover election itself. Section 146 of the Canada Business Corporations Act makes an agreement “among all the shareholders” restricting the powers of the directors “valid”, and it specifically addresses what happens to someone buying into a company that already has one: “a purchaser or transferee of shares subject to a unanimous shareholder agreement is deemed to be a party to the agreement.” That deeming provision is exactly what a rollover vendor becomes subject to — joining an acquisition vehicle's existing governance framework whether or not anyone walked them through its terms in detail.
The Act does give a rolling vendor an exit if the agreement was sprung on them: where notice of the unanimous shareholder agreement was not given before the purchase, the transferee “may, no later than 30 days after they become aware” of its existence, “rescind the transaction.” That is a narrow window, running from actual awareness rather than from closing, and it is the reason a vendor negotiating a rollover should insist on reading the target's existing unanimous shareholder agreement, if one exists, before signing — not rely on a right to walk away thirty days after discovering its terms later.
Section 146 also explains why the terms of the agreement matter so much: where shareholders under a unanimous shareholder agreement take on powers normally held by the board, they “have all the rights, powers, duties and liabilities of a director,” and the directors are relieved to that same extent. A sponsor's unanimous shareholder agreement will typically centralize exactly those powers with the majority holder. The terms a rolling vendor should push for follow directly from that structure: being a signed party to the agreement rather than simply bound by deeming provision three of section 146; defined veto rights over a specific, named list of major decisions rather than a general good-faith promise; information rights sufficient to actually monitor the business being run with the vendor's remaining equity in it; and exit mechanics — a put right after a defined holding period, and tag-along protection if the sponsor sells its own position — so the vendor is not left holding an illiquid minority stake indefinitely. None of these are statutory entitlements; they exist only if negotiated into the agreement itself.
Where negotiated protections were thin or were not honoured, section 241 of the Canada Business Corporations Act gives a minority shareholder a court remedy for conduct “that is oppressive or unfairly prejudicial to or that unfairly disregards the interests of any security holder,” with the court empowered to order, among fourteen listed remedies, a purchase of the vendor's securities, the creation or amendment of a unanimous shareholder agreement, or the variation or setting aside of a transaction. That remedy is real, but it is a lawsuit, not a negotiated position — reaching for it means the negotiated protections already failed to do their job. It is also a different remedy from the dissent right in section 190, which belongs to a shareholder objecting to a specific triggering transaction and results in being bought out and leaving the company entirely — a rolling vendor negotiating entry terms is doing the opposite, trying to stay a shareholder on workable terms rather than planning an exit from day one.
Where the rollover follows a share-purchase closing, the acquisition vehicle the vendor is rolling into is often about to amalgamate with the target, covered in amalgamating the buyer and target after closing; that same vehicle was itself likely a fresh acquisition company at the start of the deal, covered in acquiring through a newly incorporated company; and the cash-versus-equity split negotiated here is one input into the broader pricing question in pricing the difference between a share and asset deal.
A vendor sells for $4 million total: $2.8 million in cash and $1.2 million rolled into a 30% minority equity stake in the buyer's Newco. Under subsection 85(1), the parties jointly elect an amount for the $1.2 million share-for-share portion, deferring tax on it subject to the fair-market-value cap, while the $2.8 million cash boot is taxed on closing regardless. Before signing, the vendor's lawyer confirms there is no pre-existing unanimous shareholder agreement at the Newco level that the vendor would otherwise be silently bound into as a deemed party, and negotiates four specific terms into the new one being drafted for the deal: signature as a named party, veto rights over a defined list of major decisions, a put right exercisable after year three, and tag-along rights if the sponsor sells its controlling position. These four terms are negotiated deal points, not statutory rights — which is exactly why they had to be asked for rather than assumed.
No. Only the portion of the payment made in shares of the buyer's corporation qualifies for the section 85 deferral; any cash or other non-share consideration — the boot — is taxed immediately on closing regardless of the election.
A purchaser or transferee of shares subject to an existing unanimous shareholder agreement is automatically deemed a party to it under the Canada Business Corporations Act, but the specific protections a vendor actually wants — veto rights, information rights, exit mechanics — are not automatic and have to be negotiated into the agreement.
If notice was not given before the purchase, the Act allows the purchaser to rescind the transaction, but only within thirty days of actually becoming aware the agreement exists — a narrow window that starts running the moment the vendor learns of it, not on a fixed date after closing.
