Why Sellers Want a Share Sale and Buyers Want an Asset Sale in Ontario

Ask an Ontario business owner how they want to sell, and most say "shares." Ask the buyer sitting across the table, and the answer is often "assets." This isn't stubbornness — it's each side rationally pursuing its own tax and liability position, and the tug-of-war between them shapes almost every other term in the deal.

Neither position is wrong. A share sale really can save a selling shareholder a meaningful amount of tax, and an asset purchase really can protect a buyer from liabilities it never agreed to take on. Understanding why each side wants what it wants is the first step toward negotiating a structure, or a price adjustment, that both sides can live with.

This article looks at the competing incentives from both sides of the table, and how Ontario deals usually get resolved.

The Seller's Case for a Share Sale

Access to the Lifetime Capital Gains Exemption. If the seller is an individual selling shares of a qualifying small business corporation, some or all of the resulting capital gain may be sheltered personally using the Lifetime Capital Gains Exemption (LCGE). As of mid-2026, the base LCGE amount is about $1.25 million, following a 2024 increase, and it's indexed annually after that — confirm the current figure with your accountant before relying on it. The exemption is only available on qualifying shares held personally; it does not apply to a corporation's own sale of its assets.

No GST/HST on the sale itself. A share sale is generally treated as an exempt supply for GST/HST purposes, meaning no GST/HST applies to the sale of the shares themselves — one more reason many small Ontario business sales are structured as share sales wherever the buyer will agree to it.

Simplicity. Contracts, leases, and licences generally stay in the corporation's name through a share sale, which can mean fewer third-party consents to chase before closing, change-of-control clauses aside.

The Buyer's Case for an Asset Sale

A cleaner liability position. In an asset purchase, the buyer and seller identify exactly which assets are changing hands and which liabilities, if any, the buyer is assuming; liabilities not expressly assumed generally stay behind with the selling corporation. In a share purchase, by contrast, the buyer takes the corporation as it is — historical liabilities included, whether or not anyone currently knows about them.

A reset cost base. An asset purchase can let a buyer reset the tax cost of the purchased assets to reflect what it actually paid, which may support larger depreciation claims in future years. A share purchase generally does not reset the underlying assets' cost base inside the corporation.

Cherry-picking. An asset structure lets a buyer negotiate around specific assets, contracts, or liabilities it doesn't want — a stale lease, pending litigation, an unwanted product line — in a way a share purchase doesn't easily allow.

Where the Two Positions Collide

The seller's preferred structure is often the buyer's least preferred one, and vice versa. A few flashpoints come up in almost every negotiation:

• The seller wants the LCGE and GST/HST exemption available on shares; the buyer wants the liability protection and cost-base reset available on assets.
• The seller wants third-party consents avoided; the buyer wants the chance to walk away from an unassignable or unfavourable contract.
• The seller wants a clean exit from every historical liability; the buyer wants confidence that nothing unpleasant is hiding in the corporation's past.

How Ontario Deals Usually Get Resolved

Deals rarely end with one side simply accepting the other's preferred structure for free. More often, the structure question gets resolved alongside price and risk allocation:

1. Price adjustment. If the seller gives up the tax advantage of a share sale, the price sometimes moves to compensate for the seller's higher effective tax cost.
2. Stronger representations and indemnities. If the buyer agrees to a share purchase, it typically insists on more detailed representations, a larger holdback, and a longer survival period for the representations that matter most.
3. Representation and warranty insurance. Increasingly used to bridge the liability gap without forcing either side to give up its preferred structure entirely.
4. Hybrid tax planning. In some deals, the parties agree on a share sale while using separate tax mechanisms to give the buyer some of the cost-base benefit it would otherwise only get from an asset purchase. This is genuinely technical territory for a tax accountant or tax lawyer, not something to assume applies to your deal.
