Asset sale vs share sale in Canada

Almost every Canadian small business sale eventually comes down to one structural question that shapes everything else in the deal: is the buyer purchasing the company’s assets, or the shares of the company itself? The two structures aren’t interchangeable variations on the same transaction — they produce different tax outcomes, transfer different risks, and are negotiated differently, and the two sides of a deal often start out wanting opposite answers for reasons that are entirely rational on both sides.

What actually changes hands

In an asset sale, the buyer and the seller’s corporation agree on a specific list of assets, such as equipment, inventory, contracts, goodwill and sometimes real property, and, usually, a specific list of liabilities the buyer is willing to assume. Everything not on that list stays behind with the seller’s original corporation, including its past. In a share sale, the buyer instead purchases the shares of the corporation itself, stepping directly into the seller’s shoes — the company, its contracts, its employees, its history and, critically, any liability that existed before closing but hasn’t surfaced yet, all come along with it.

Why buyers usually prefer an asset sale

An asset sale lets a buyer choose exactly what to take on and, just as importantly, what to leave behind. Old liabilities, pending claims, or contracts the buyer doesn’t want simply aren’t part of the deal. That control over exposure is the main reason buyers, and their lenders, tend to favour an asset structure by default, particularly when the target’s history or record-keeping is harder to fully verify.

Why sellers usually prefer a share sale

For a seller, a share sale is typically taxed once, personally, as a capital gain that may qualify, in whole or in part, for the lifetime capital gains exemption if the corporation and shares meet the relevant conditions. An asset sale, by contrast, is generally taxed inside the corporation first, with a separate tax event when proceeds are later extracted, a two-step process that, for many sellers, produces a smaller after-tax result for the same headline price. That difference alone explains why many sellers push for a share structure even when a buyer’s first instinct is to ask for an asset deal.

How the two are taxed differently, at a mechanism level

• A share sale generally produces a capital gain to the individual seller, potentially eligible for the lifetime capital gains exemption where conditions are met.
• An asset sale generally produces gains and income taxed inside the corporation first, capital gains on some assets, recaptured depreciation on others, goodwill taxed under its own rules, before a second, separate tax event when proceeds are extracted.
• Sales tax treatment differs too: an asset sale generally attracts GST/HST unless a specific election applies, while a share sale is typically treated differently for sales tax purposes.

Liability and employment differences

Beyond tax, the two structures transfer very different risk. A share sale carries forward every liability the corporation had before closing, known or unknown, unless specifically addressed through representations, warranties and indemnities in the purchase agreement. An asset sale generally lets the buyer leave old liabilities behind, but raises its own questions, around whether employees are considered continuously employed or newly hired, and whether existing contracts and leases can actually be assigned to the buyer at all, since not every counterparty is required to agree.

Environmental and contract risk factor in too

The choice between structures also shows up in less obvious places, like environmental liability and supplier relationships. A share sale carries forward responsibility for any contamination or environmental non-compliance tied to the corporation’s history, even if it happened years before the current owner took over, while an asset sale can sometimes let a buyer avoid inheriting that specific liability depending on how the deal is structured. Supplier and customer contracts raise a related question: some agreements contain clauses that let the other party walk away or renegotiate if control of the company changes, which matters more in a share sale than in an asset sale, where contracts are being assigned deliberately rather than carried over automatically.

How this actually gets negotiated

Because buyers and sellers often start from opposite preferences, structure is frequently one of the first substantive negotiating points in a deal, sometimes settled before price is even finalized. It isn’t unusual for a purchase price to be adjusted specifically to reflect which structure is used, compensating whichever side ends up bearing a less favourable tax or liability outcome. Getting an accountant and a lawyer involved on this question early, rather than after a letter of intent has already fixed the structure, gives both sides more room to negotiate a trade-off that works for everyone.
