Asset deal or
share deal?

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

Almost every time someone comes to me to buy or sell an incorporated business in Ontario, one of the first real decisions we have to make is structural: is this going to be an asset purchase or a share purchase? It sounds like a technical, lawyerly distinction, and people are often tempted to wave it off and "let the lawyers sort it out." That is a mistake. The choice between the two structures drives your liability exposure, your tax bill, what happens to the employees, and whether the contracts and leases the business runs on come along for the ride.

Here is the part that surprises people most: the buyer and the seller usually want opposite things. Buyers generally prefer asset deals; sellers generally prefer share deals. That tension is not a quirk — it falls straight out of how the law treats liability and tax in each structure. Once you understand why each side leans the way it does, the negotiation that follows makes a lot more sense.

In this guide I will walk through what each structure actually is, the two big differences that drive everything — liability and tax — and then the practical questions that come up every time: what happens to staff, whether contracts and leases transfer, and how the structure gets negotiated. None of this is legal or tax advice for your specific deal; the right answer depends on your numbers, and you should get a lawyer and an accountant involved early. But after years of doing these transactions, this is the framework I want every buyer and seller to start with.

The two ways to buy a business

When the business you are buying or selling is run through a corporation, there are two basic ways to do the deal, and almost everything in this article flows from the difference between them.

In an asset purchase, the buyer buys selected assets of the business — the things the business is made of. That can include equipment, inventory, the customer list, intellectual property, goodwill, and the benefit of certain contracts. The corporation that owned those assets stays behind with the seller. The buyer is essentially picking up the business and leaving the legal shell where it was.

In a share purchase, the buyer buys the shares of the corporation that owns the business. The corporation itself changes hands, and it comes exactly as it is — with everything it owns and everything it owes, every contract it has signed, every employee it employs. The business does not move; the ownership of the company that runs it does.

That distinction — buying the assets out of the company versus buying the company itself — is the fork in the road. Both are completely legitimate ways to do a deal. Which one you want depends almost entirely on which side of the table you are sitting on, and why. For a wider view of the whole transaction, my checklist for buying a business in Ontario walks through the steps around this decision.

What an asset purchase is

An asset purchase is exactly what it sounds like: the buyer buys the assets that make up the business, item by item or category by category, and the parties agree precisely what is included and what is left out. A typical asset deal might transfer the equipment, the inventory, the intellectual property, the goodwill and brand, the customer relationships, and the benefit of key contracts — while leaving behind, say, an old lawsuit, a disputed tax bill, or a vehicle the seller wants to keep.

The defining feature is selectivity. Because you are agreeing to a list of what transfers, you can take the parts of the business you want and leave the parts you do not. That selectivity is also what makes an asset deal more work in some respects: each asset and each contract has to actually be transferred or assigned, which I will come back to when we talk about contracts, leases, and consents.

One thing worth flagging early, because it used to be a real trap: Ontario's Bulk Sales Act once required a buyer in an asset sale to notify the seller's creditors before closing, and missing that step could unwind the deal. That statute was repealed in 2017, so the old creditor-notification process no longer applies to Ontario asset sales. You still deal with creditor and tax exposure through due diligence and the purchase agreement, but the formal Bulk Sales Act compliance step is gone — and asset deals are simpler for it.

What a share purchase is

A share purchase takes a completely different shape. Instead of cherry-picking assets, the buyer buys the shares of the corporation, and with them gets the whole company in one move. Every asset the company owns, every contract it has signed, every employee on its payroll, and — this is the crucial part — every liability it carries all come with the shares automatically. Nothing has to be individually transferred, because nothing actually moves; the company is the same company, just under new ownership.

That makes a share deal mechanically simpler in some ways. You do not have to assign each contract or re-paper each lease, because the corporation that holds them is unchanged. For a business that runs on dozens of contracts, permits, and licences, that simplicity is a genuine advantage, and it is one reason some buyers accept a share structure even though they would instinctively prefer assets.

But the same feature that makes it simple is what makes it riskier for a buyer. When you buy the whole company, you also buy all of its problems, including the ones nobody has told you about. That is why share deals live and die on due diligence and on the protections written into the agreement. We will get to that, but the headline is this: in a share deal, you are not buying a business — you are adopting a corporation, history and all.

Liability — the biggest difference

If you remember one thing from this article, make it this. The single biggest difference between an asset deal and a share deal is what happens to the business's liabilities.

In a share purchase, the buyer gets the entire corporation — and that means all of its liabilities, known and hidden. The unpaid tax assessment nobody mentioned, the disgruntled former employee who has not sued yet, the warranty claims that have not surfaced, the environmental issue buried in a property file: if the corporation owes it, the buyer now owns it. Nothing in the structure filters these out. This is precisely why representations, warranties, and indemnities — and genuinely thorough due diligence — matter most in a share deal. Those contractual protections are how a buyer shifts the risk of hidden liabilities back onto the seller, because the structure itself gives no protection at all.

In an asset purchase, the picture is very different. The buyer generally assumes only the liabilities it expressly agrees to take on. If a liability is not on the list the buyer agreed to assume, it stays with the seller and the seller's corporation. Unknown and contingent liabilities — the ones nobody can see at closing — are left behind. That is an enormous comfort to a buyer, and it is the single biggest reason buyers usually prefer asset deals. You are buying the business, not the corporate baggage.

A quick example makes the point. Imagine a company that, two years after you buy it, gets hit with a large reassessment for taxes from before your purchase. If you bought the shares, that liability is now yours — it belongs to the corporation you own — and your only recourse is whatever indemnity you negotiated against the seller. If you bought the assets, that old tax bill generally stayed with the seller's company, and it is not your problem at all. Same business, same dollar figure, completely different outcome — driven entirely by the structure you chose.

Tax — the other big driver (and the LCGE)

If liability is the reason buyers lean toward assets, tax is the reason sellers lean toward shares — and on the seller's side, the tax difference is often even more decisive. I want to be careful here: tax figures change, the rules are detailed, and your accountant has to run the actual numbers. But the broad shape of it is consistent enough to plan around.

The headline for sellers is the lifetime capital gains exemption (LCGE). On a share sale, an individual seller may be able to use the LCGE to shelter the capital gain on qualified small business corporation (QSBC) shares — currently up to around $1.25 million, though the amount is indexed and changes over time, so confirm the current figure with your accountant. Where it applies, the LCGE can dramatically reduce, or even eliminate, the tax on a sale. The critical point: the LCGE applies to qualifying share sales, not asset sales. Sell the assets instead of the shares, and the exemption is simply not on the table for that gain. For an individual owner with shares that qualify, that difference can be worth hundreds of thousands of dollars, which is why a seller will often fight hard for a share structure.

The buyer's tax interest points the other way. In an asset sale, a buyer can often "step up" the cost base of the assets to what they paid and claim future depreciation against income — a real, ongoing benefit. The flip side is on the seller: in an asset sale the seller may face more tax, potentially at two levels, because the company sells the assets (triggering tax inside the corporation) and then has to distribute the proceeds out to the owner (potentially triggering tax again). That two-layer problem is a big part of why an asset sale can leave a seller worse off than a clean share sale.

So the tax dynamic mirrors the liability dynamic almost perfectly: the structure that is best for one side tends to be worst for the other. The tax advantage of a share sale is the single biggest reason sellers usually prefer share deals. Because the stakes are this large and this technical, an accountant has to be in the room early — ideally before any structure is even named in a letter of intent. My guide on business exit planning in Ontario goes deeper on getting the company "sale-ready," including the steps that help shares qualify for the LCGE in the first place.

Employees — what happens to staff in each

The people working in the business are one of the first things a thoughtful buyer or seller asks about, and the two structures handle them very differently on paper — but, importantly, end up much closer than people expect.

In a share purchase, the employer corporation stays the same. The company that employs the staff has not changed; only its ownership has. So the employees simply continue, uninterrupted. Their employment contracts, their accrued entitlements, their seniority — all of it carries on as if nothing happened, because for employment-law purposes nothing did. There is no termination and no re-hiring.

An asset purchase looks more disruptive at first glance. Technically, the seller terminates the employees and the buyer re-hires them, because the employer is changing from the seller's corporation to the buyer. But here is the part asset buyers sometimes hope to exploit and cannot: under Ontario's Employment Standards Act, a buyer who continues the business is a successor employer. That means each employee's prior service with the seller is "stitched together" with their service under the buyer for ESA entitlements — vacation, notice, and severance. The clock does not reset to zero.

The practical takeaway is important: an asset buyer does not escape accrued employee entitlements just by structuring the deal as an asset purchase. A long-tenured employee carries that tenure across the deal. So if you are buying assets and planning to keep the staff, price and document those continuing entitlements properly; do not assume you are inheriting a clean slate. And whichever structure you use, decide deliberately which employees you want, how the offers (or continuations) are handled, and how accrued vacation and similar liabilities are dealt with in the price.

Contracts, leases, and consents

A business is held together by its contracts — supplier agreements, customer contracts, the premises lease, software licences, permits. How those move (or do not move) is one of the most practical differences between the two structures, and one of the most common places a deal hits friction.

In a share deal, contracts and leases generally stay in place, because the corporation that signed them is unchanged. The other parties are still dealing with the same legal entity, so in most cases there is nothing to re-sign. The catch to watch for is change-of-control clauses. Some contracts and leases say that if the ownership of the company changes, the other side gets rights — to consent, to renegotiate, or to terminate. So even in a share deal where "nothing moves," a change-of-control clause can put a key contract back on the table. Spotting these in due diligence is essential.

In an asset deal, the issue is sharper. Because the buyer is a different entity from the seller's corporation, key contracts, leases, permits, and licences usually have to be assigned to the buyer — and assignment frequently needs the other party's consent. The classic example is the premises lease: a commercial lease almost always requires the landlord's consent to assign, which means your landlord effectively has a say in your purchase, and can use that leverage to extract terms. The same is true of important supplier or customer contracts that prohibit assignment without consent. If you are buying assets, you have to map out early which third-party consents you need, because a missing consent on a critical contract or lease can stall or sink a closing. If a lease is central to the business, a commercial lease lawyer should be involved on the assignment from the start.

Why buyers prefer assets and sellers prefer shares

By now the pattern should be clear, and it is worth pulling together in one place, because this is the heart of every negotiation I run.

Buyers usually prefer asset deals for two reasons. First and biggest is liability: they take on only the liabilities they agree to, and leave the unknown and contingent ones behind. Second is tax: they can step up the cost base of the assets and claim future depreciation. A clean slate plus a depreciation benefit is a powerful combination for a buyer.

Sellers usually prefer share deals for two mirror-image reasons. First and biggest is tax: the lifetime capital gains exemption can shelter a large part of the gain on qualifying QSBC shares, which is simply not available on an asset sale. Second is a clean exit: in a share sale the buyer takes the corporation with all of its liabilities, so the seller can walk away without being left holding a leftover company and a second layer of tax.

So you have a genuine, structural tug-of-war built into almost every deal: the buyer wants assets, the seller wants shares, and both are being perfectly rational. Neither side is being difficult — they are responding to the way liability and tax actually work. Understanding that is what lets you negotiate the structure on the merits instead of treating the other side's preference as unreasonable.

Can a deal be partly asset and partly share?

Sometimes, yes, though it is less common in smaller transactions. Parties occasionally carve out certain assets or liabilities, or use a pre-closing reorganization to put the business in the right shape before a share sale. There are also tax-driven techniques an accountant may suggest to bridge the gap between what the buyer wants and what the seller wants. These get complex quickly, and they are exactly the kind of thing you want professional advice on rather than improvising. The point is simply that "asset versus share" is the starting framework, not always the final word.

How the structure gets negotiated

Because the two sides naturally pull in opposite directions, the structure is one of the first real negotiations in any sale — and it is usually settled before lawyers draft the detailed agreement. In practice it often gets pinned down at the letter of intent or term sheet stage, which is why I tell clients not to sign one of those without advice. The structure named in the LOI sets the tone for everything that follows.

The negotiation is rarely just "assets or shares" in a vacuum — it is bundled with price. A buyer who agrees to a share deal (taking on more risk) will often want a lower price, stronger indemnities, or part of the price held back in escrow to cover hidden liabilities. A seller who insists on a share sale to capture the LCGE may have to give ground on price or warranties in exchange. The structure and the economics are negotiated together, because each side is effectively pricing the risk and tax consequences of the chosen structure.

What I always tell clients is that the structure decision should be made with both a lawyer and an accountant in the room, and made early. The choice is heavily tax-driven and heavily negotiated, and once it is locked into a signed letter of intent it is awkward and sometimes costly to revisit. Get the analysis done before you commit to a number, not after.

Due diligence in each structure

Due diligence — the investigation a buyer does before closing — matters in both structures, but its weight and focus shift depending on which one you are in.

In a share deal, due diligence is everything. Because the buyer is inheriting the whole corporation and all of its liabilities, the investigation has to be deep and broad: corporate records and the minute book, tax filings and potential reassessments, litigation and threatened claims, employment matters, contracts and change-of-control clauses, liens and security, and any regulatory or environmental exposure. Whatever due diligence misses, the buyer owns. This is why share deals are document-heavy and why the representations, warranties, and indemnities in the agreement are negotiated so hard — they are the safety net for everything diligence cannot surface.

In an asset deal, the buyer is more insulated from hidden liabilities, so some of that risk-driven diligence is lighter. But the focus shifts to a different set of questions: does the seller actually own the assets free and clear, are there liens or security registered against them, which contracts and leases need consents to assign, and are the permits and licences transferable? An asset buyer worries less about the corporation's hidden past and more about whether the specific assets and contracts they want can cleanly be brought across. Both kinds of diligence protect you; they just point at different risks.

Common mistakes

A handful of mistakes come up again and again on these deals, and each one is avoidable with the right advice up front.

Choosing the structure without an accountant. The asset-versus-share decision is fundamentally a tax decision as much as a legal one. Picking a structure — or letting the other side pick it — before anyone has modelled the tax outcomes is how sellers lose access to the LCGE and how buyers give up a step-up they could have had.

Assuming an asset deal escapes employee entitlements. I see asset buyers assume the employees' clocks reset to zero. They do not. The successor-employer rule under the Employment Standards Act stitches prior service to new service for vacation, notice, and severance. Price that in.

Forgetting about consents. In an asset deal, a critical lease or contract that cannot be assigned without consent can hold up the entire closing. Buyers who leave consents to the last minute discover that the landlord or a key supplier has more leverage than they expected.

Treating a share deal's "simplicity" as safety. A share deal is mechanically simpler because nothing has to be assigned — but that simplicity hides the biggest risk, which is inheriting unknown liabilities. Light due diligence on a share deal is dangerous, not efficient.

Thinking the old Bulk Sales Act still applies. Some older checklists and templates still reference creditor notifications under the Bulk Sales Act on asset sales. In Ontario that step was repealed in 2017. Following stale instructions wastes time and signals advice that has not kept current.

Signing a letter of intent without advice. The structure, price framework, and key terms are often effectively set in the LOI. Treat that document casually and you can box yourself into a structure that costs you dearly later. If the other side has, in effect, made promises you are relying on, make sure you understand which parts of the LOI bind and which do not before you sign.

Key takeaways

• Two structures, one big fork. An asset purchase buys selected assets out of the company; a share purchase buys the company itself, with everything it owns and owes.
• Liability is the biggest difference. A share buyer inherits all liabilities, known and hidden; an asset buyer generally takes on only the liabilities it agrees to assume — which is why buyers usually prefer assets.
• Tax drives the seller's side. The lifetime capital gains exemption can shelter the gain on qualifying QSBC shares in a share sale (around $1.25 million, indexed — confirm with your accountant), but it does not apply to asset sales, which is why sellers usually prefer shares.
• Employees carry their service across. In a share deal they simply continue; in an asset deal the ESA successor-employer rule stitches prior service to new service, so accrued entitlements survive.
• Contracts, leases, and consents. Share deals keep contracts in place (watch change-of-control clauses); asset deals usually require assignments and third-party consents, like the landlord's on a lease. The old Bulk Sales Act step was repealed in 2017.

Frequently asked questions

What is the difference between an asset purchase and a share purchase?

These are the two basic ways to buy or sell an incorporated business. In an asset purchase, the buyer buys selected assets of the business — equipment, inventory, contracts, goodwill — and the corporation that owned them stays with the seller. In a share purchase, the buyer buys the shares of the corporation itself, so they get the whole company exactly as it is, including everything it owns and everything it owes. The corporation does not change hands in an asset deal; in a share deal, ownership of the corporation is what changes.

Which is better for the buyer — an asset or share purchase?

Buyers usually prefer an asset purchase. The biggest reason is liability: in an asset deal, the buyer generally takes on only the liabilities it expressly agrees to assume, leaving unknown and contingent liabilities behind with the seller. There is also a tax advantage — the buyer can often "step up" the cost base of the assets and claim future depreciation. That said, "usually" is not "always." An asset deal can mean re-papering contracts, getting consents, and transferring permits, which can be more cumbersome than simply buying the shares.

Which is better for the seller — an asset or share purchase?

Sellers usually prefer a share purchase, and the main reason is tax. On a qualifying share sale, an individual seller may be able to use the lifetime capital gains exemption to shelter a large part of the gain on qualified small business corporation shares. The exemption applies to share sales, not asset sales. A share sale also lets the seller walk away cleanly, since the buyer takes the corporation with its liabilities. In an asset sale the seller can face more tax, sometimes at two levels, and is often left holding the leftover company.

What happens to the business's liabilities in each structure?

This is the single biggest legal difference. In a share purchase, the buyer gets the whole corporation, which means all of its liabilities come along — known, unknown, and hidden. That is why thorough due diligence and strong representations, warranties, and indemnities matter most in a share deal. In an asset purchase, the buyer generally assumes only the liabilities it specifically agrees to take on. Unknown and contingent liabilities stay with the seller. This protection is the main reason buyers tend to favour asset deals over share deals.

What is the lifetime capital gains exemption?

The lifetime capital gains exemption (LCGE) lets an individual shelter capital gains on the sale of qualified small business corporation (QSBC) shares up to a lifetime limit — currently around $1.25 million, though the figure is indexed and changes over time, so confirm the current number with your accountant. It can dramatically reduce or eliminate tax on a sale, but it applies only to qualifying share sales, not asset sales, and only where the shares and the corporation meet specific tests. This is one of the biggest reasons sellers push for a share deal.

What happens to employees in an asset sale vs. a share sale?

In a share purchase the employer corporation does not change, so employees simply continue working, uninterrupted. In an asset purchase, the seller technically terminates the employees and the buyer re-hires them. But under Ontario's Employment Standards Act, a buyer who continues the business is a successor employer, so each employee's prior service with the seller is stitched together with their service under the buyer for entitlements like vacation, notice, and severance. So an asset buyer does not escape accrued employee entitlements just by structuring the deal as an asset purchase.

Do contracts and leases transfer automatically?

It depends on the structure. In a share deal, contracts and leases generally stay in place because the corporation that signed them is unchanged — but watch for "change of control" clauses, which can be triggered even though the legal party stays the same. In an asset deal, key contracts, leases, permits, and licences usually have to be assigned to the buyer, and assignment often needs the other party's consent. A commercial lease, for example, typically cannot be assigned without the landlord's consent, so the landlord effectively has a say in your deal.

Do I still have to comply with the Bulk Sales Act?

No. Ontario's Bulk Sales Act used to require a buyer in an asset sale to notify the seller's creditors before closing, and it created real headaches when that step was missed. It was repealed in 2017, so that old compliance requirement no longer applies to Ontario asset sales. You should still address creditor and tax issues through due diligence, indemnities, and clearance certificates where appropriate, but the formal Bulk Sales Act notice process is gone, which has made asset deals in Ontario noticeably simpler.

How is the purchase price taxed differently?

The structure changes who pays tax and how much. On a share sale, the seller realizes a capital gain on the shares and may be able to use the lifetime capital gains exemption on qualifying QSBC shares. On an asset sale, the corporation sells the assets, which can trigger tax inside the company — and if the proceeds are then distributed to the owner, there can be a second layer of tax, so the seller may pay more overall. The buyer, meanwhile, often prefers an asset deal because it can step up the cost base and claim future depreciation. Always run the numbers with an accountant.

Do I need a lawyer and an accountant for this?

Yes — and both, early. The asset-versus-share decision is heavily tax-driven, so an accountant should model the tax outcomes for each structure before anyone commits. A lawyer handles the legal side: due diligence, the purchase agreement, representations, warranties and indemnities, assignments and consents, employee transfers, and closing. The structure you choose drives the entire deal, and the cheapest mistake is the one you avoid by getting advice before you sign a letter of intent rather than after. This is not a do-it-yourself transaction.

Final thoughts

Asset versus share is the decision that quietly shapes a business sale from start to finish. It is why buyers and sellers so often want opposite things, and why a transaction that looks simple on the surface — "I'm buying Bob's company" — is really a negotiation over who carries the liabilities and who captures the tax advantages. Get that structure right, and the rest of the deal tends to fall into place. Get it wrong, and you can be paying for it years later.

The most important practical advice I can give is the least glamorous: bring in a lawyer and an accountant before you commit to a structure or a price, not after. Whether you are on the buy side and want a lawyer to help you buy a business, on the sell side and want help to sell your business cleanly, or you are weighing a related move like buying a franchise, the structure conversation should happen first. A focused business lawyer and your accountant, working together early, will save you far more than they cost.
