Asset Purchase vs Share Purchase in Ontario: What Is the Difference?

If you are buying or selling a business in Ontario, one of the first questions that will come up is: should this be structured as an asset purchase or a share purchase? It sounds like a technical detail, but the choice can have real consequences for your taxes, your exposure to risk, and your obligations to employees and landlords.
This article breaks down the basic difference between the two structures and explains why certain issues, like liabilities, taxes, employees, contracts, and leases, can make one option more attractive than the other in a given situation. Every deal is different, so this is general information only. You should speak with a lawyer and an accountant before making any decisions.
The Basic Idea: What Are You Actually Buying?
The simplest way to think about it is this:
In an asset purchase, you buy specific things from the business like its equipment, customer lists, inventory, goodwill, intellectual property, and so on. You are not buying the compan
In a share purchase, you buy the shares of the corporation that owns the business. You are essentially stepping into the seller’s shoes as the new owner of the company itself.
That distinction matters a lot, and the reasons why come into focus when you start looking at what else comes along for the ride.
Liabilities: What You Might Be Taking On
One of the biggest practical differences between the two structures has to do with liabilities, meaning the debts, obligations, and legal risks attached to the business.
In an asset purchase, you generally get to choose what you are taking on. If the seller has outstanding debts, unresolved lawsuits, or tax problems, those typically stay with the seller and the old corporation. You start with a cleaner slate.
In a share purchase, you are buying the whole company, which means you are also inheriting everything that came before including things you may not know about yet. Unknown tax liabilities, pending litigation, or undisclosed obligations could become your problem. This is one of the main reasons buyers often prefer an asset purchase, especially when they do not have a long history with the business and cannot fully assess what might be lurking.
Sellers, on the other hand, sometimes prefer a share purchase, partly for tax reasons (more on that below) and partly because it can be a cleaner exit.
Taxes: The Picture Can Be Very Different
Tax treatment is another area where the two structures diverge significantly, and it is often the reason a seller pushes for one structure over the other.
If the seller is selling shares of a qualifying small business corporation, they may be eligible for the lifetime capital gains exemption under the Income Tax Act, which can shelter a significant amount of the gain from tax. That exemption does not apply to an asset sale, which is part of why sellers often prefer a share purchase from a tax perspective.
For buyers, the picture is often the opposite. In an asset purchase, there may be more flexibility around how the purchase price is allocated between different asset categories, which can affect depreciation and future tax deductions. A share purchase does not offer the same kind of flexibility.
Tax rules are complex and depend heavily on the specific facts of the transaction. Working with an accountant who understands business acquisitions in Ontario is strongly recommended before settling on a structure.
Employees: What Happens to the Existing Team?
The treatment of employees is another area where structure matters. Ontario’s Employment Standards Act, 2000 provides certain protections for employees, and the rules can apply differently depending on how the deal is put together.
In a share purchase, the employees are working for the same corporation before and after the sale. The employer of record does not change, so their continuity of employment is generally not disrupted. Any accumulated notice entitlements and benefits typically carry over.
In an asset purchase, the situation is more nuanced. Depending on the circumstances, the buyer may be considered a successor employer under Ontario employment law, which can mean taking on certain obligations to existing staff. Whether employees are treated as having continuous employment or as new hires can affect their entitlements going forward, and this is something worth addressing clearly in the purchase agreement.
If the business has senior employees with significant service, or union agreements, the employment picture deserves careful attention before closing.
Contracts: Not Everything Transfers Automatically
Most businesses run on contracts, with suppliers, customers, service providers, and sometimes key individuals. What happens to those contracts in a deal depends on how the transaction is structured.
In a share purchase, the corporation remains the contracting party, so existing contracts generally continue without interruption. This can be a real advantage when the business has valuable long-term agreements that would be difficult to renegotiate.
In an asset purchase, contracts do not automatically transfer to the buyer. Many contracts include clauses that restrict assignment to a third party, or require consent from the other party before they can be transferred. If a key supplier agreement or customer contract requires the other side to approve a transfer, and they refuse, that is a problem. Identifying which contracts are critical and whether they can be assigned is an important part of due diligence in any asset deal.
The Lease: A Frequently Overlooked Issue
If the business operates out of a leased space which most do the commercial lease is often one of the most important documents in the deal, and it can create unexpected complications.
In a share purchase, the tenant on the lease is the corporation, and the corporation is not changing. In many cases, no landlord consent is required because the legal tenant stays the same.
In an asset purchase, you are typically asking to take over the lease or have it assigned to you. Most commercial leases include assignment clauses that require the landlord’s consent before the lease can be transferred to a new party. The landlord may have the right to refuse, to impose new terms, or to require personal guarantees. If you are counting on being able to operate from the same location after closing, confirming that the lease can actually be assigned to you and on acceptable terms is critical to do before you finalize anything.
How much time is left on the lease also matters. A business with only a few months remaining on its lease is in a very different position than one with a long-term lease in a desirable location.
So Which Structure Is Right for You?
There is no universal answer. In many deals, the structure ends up being a negotiation between buyer and seller, because each side may have different tax or risk priorities. What matters is that both sides understand the implications before agreeing to anything.
A few things worth keeping in mind:
Buyers often lean toward an asset purchase because it limits exposure to unknown liabilities.
Sellers often prefer a share purchase because of potential tax advantages, including the capital gains exemption.
The right answer depends on the specifics of the business, the deal, and the people involved.
Due diligence is important regardless of structure. Reviewing financial records, contracts, leases, employee agreements, and any outstanding liabilities before you sign anything can save significant problems down the road.
Speaking with a business lawyer early in the process before the deal gets too far along can help you understand your options, spot potential issues, and make sure the structure actually works in your favour.
FREQUENTLY ASKED QUESTIONS
Q: As a buyer, is an asset purchase always the safer option?
Not necessarily. An asset purchase can reduce your exposure to certain liabilities, but it also comes with its own complications, particularly around contracts, leases, and employees. In some cases, a share purchase may actually be simpler, especially if the business has complex supplier relationships or a valuable lease that would be difficult to transfer. The right structure depends on the specific deal and the results of due diligence. A lawyer can help you evaluate the trade-offs.
Q: What is the lifetime capital gains exemption, and does it always apply to share sales?
The lifetime capital gains exemption is a provision under Canada’s Income Tax Act that may allow an individual to shelter a significant amount of capital gains from tax when selling shares of a qualifying small business corporation. It does not apply automatically to every share sale there are specific conditions the corporation and the seller must meet. Whether the exemption applies in a given situation is something an accountant familiar with business transactions in Ontario can advise on.
Q: What happens to the business name in an asset purchase?
In an asset purchase, the business name is one of the assets that can be included in the deal but it has to be specifically addressed in the purchase agreement. The business name is not automatically transferred just because you are buying the business. If the name is important to you, make sure it is clearly listed as part of what you are acquiring, and that any necessary steps are taken to register or transfer it properly under Ontario’s business name registration rules.
Q: Do I need a lawyer for a business purchase in Ontario, or can I handle it myself?
There is no legal requirement that you use a lawyer, but business purchases in Ontario even relatively small ones involve complex legal documents, potential liabilities, and decisions that can have long-term consequences. Mistakes in the purchase agreement or oversights in due diligence can be expensive and difficult to fix after closing. Having a business lawyer review the transaction and advise you on your options is generally money well spent, particularly given what is at stake.
