Should I Buy the Assets or the Shares of a Business in Canada?
The decision depends on your tax position, tolerance for inherited liabilities, and whether you need to preserve specific permits or contracts. Asset purchases typically give you a tax basis step-up and liability protection; share purchases preserve corporate continuity and often require less contract rework, but expose you to all pre-closing liabilities of the business.
What the Two Structures Mean
In an asset purchase, you acquire specific assets — equipment, inventory, intellectual property, customer lists — and assume only the liabilities you explicitly agree to take on. Most historical liabilities remain with the seller's corporate shell. In a share purchase, you acquire all shares of the corporation and inherit everything: all assets, all liabilities, all contracts, and all potential contingent liabilities of that entity.
The asset purchase gives you control over what you're buying. You can exclude unwanted assets or contracts selectively, reducing your purchase price and future operational risk. The share purchase is an all-or-nothing transaction — the corporation continues operating unchanged, and you step into the seller's shoes as the new owner of that legal entity.
Tax Treatment for the Buyer
Asset purchases allow you to step up the tax basis of purchased assets to fair market value, creating future tax deductions through depreciation. You can claim capital cost allowance (CCA) on the stepped-up value of eligible depreciable assets, which reduces your taxable income in future years.
In share purchases, you do not receive a step-up in the tax basis of the corporation's underlying assets. The historical tax values — undepreciated capital cost (UCC) for depreciable property — carry forward unchanged. This means lower future CCA deductions for you compared to an asset purchase of the same business.
When a business has significant accumulated tax losses (non-capital losses) or unclaimed capital cost allowance pools, those attributes remain with the corporation in a share purchase and may provide future tax benefits to you as the new owner. However, the Income Tax Act imposes restrictions on the use of losses after an acquisition of control, including specific change-of-control rules that may limit or eliminate your ability to use pre-acquisition losses. Confirm with a tax advisor whether the losses you're counting on will survive the transaction.
Liability Exposure Differences
In asset transactions, you bear lower risk of inheriting unknown or contingent liabilities — tax audits, lawsuits, environmental claims — compared to share purchases. Environmental liabilities, product liability claims, and tax reassessments remain with the selling corporation unless you explicitly assume them in the purchase agreement.
Share purchases expose you to all pre-closing liabilities of the corporation, including latent claims not discovered during due diligence. Buyers in share deals typically negotiate representations, warranties, and indemnities from the seller to mitigate unknown liability risks, sometimes backed by holdbacks or escrows. This does not eliminate the risk — it shifts part of the financial consequence back to the seller if an undisclosed liability surfaces. Whether the seller has the financial capacity to honor that indemnity years after closing is a separate question.
Transaction Costs and Complexity
Asset purchases generally involve higher legal and accounting costs at closing. You must itemize and transfer individual assets, assign contracts, and obtain third-party consents where required. Asset purchases typically require individual assignment or novation of key contracts, which may trigger third-party consent requirements or renegotiation.
Share purchases are administratively simpler at closing — you acquire shares and the corporation continues operating unchanged — but require more extensive due diligence to assess hidden liabilities. Share purchases transfer all existing contracts, leases, licenses, and permits without requiring third-party consents, except where change-of-control clauses exist in those agreements. You inherit the benefit of continuity, but you also inherit every clause, every commitment, and every contractual obligation the business already has.
In asset purchases, employment relationships may transfer by operation of law under successor employer provisions in some jurisdictions, or require new employment agreements, potentially triggering notice or severance obligations. In share purchases, employment relationships continue uninterrupted because the employer — the corporation — remains the same legal entity, avoiding severance or notice obligations under common law or employment standards legislation.
GST/HST Considerations
Asset purchases typically require GST/HST on the purchase price of taxable assets unless the transaction qualifies as a going concern. A going concern exemption applies when all or substantially all — at least 90% — of the property capable of being used in a business is transferred to you and you intend to continue operating the business. If the exemption applies, no GST/HST is charged on the asset sale. If it does not apply, you pay GST/HST on top of the purchase price, increasing your upfront cash requirement.
Share purchases are generally exempt from GST/HST because shares are financial instruments, not taxable supplies. This eliminates a significant cash outlay at closing compared to a non-exempt asset purchase.
When Share Purchases Make Sense
In industries with valuable licenses, permits, or regulatory approvals that are difficult or impossible to transfer — liquor licenses, specialized healthcare permits — buyers commonly prefer share purchases to preserve the corporate entity holding those approvals. Transferring or reapplying for a critical license can delay closing by months or make the transaction infeasible.
Share purchases are more common in middle-market transactions above $5 million, where the complexity and cost of transferring numerous contracts, employees, and permits favor continuity of the corporate entity. The larger the business, the more contracts and relationships are embedded in the legal entity itself, and the more disruptive an asset purchase becomes.
When Asset Purchases Make Sense
Asset purchases are more common in small business transactions under $5 million, where buyers prioritize tax basis step-up and liability insulation over administrative simplicity. The tax benefit of stepping up depreciable assets often outweighs the incremental legal cost of transferring them individually.
You typically use an asset purchase structure when acquiring a division or subset of a seller's business, allowing you to carve out only the desired assets and avoid unwanted operations. If the seller runs three product lines and you only want one, an asset purchase is the natural structure.
Asset purchases also make sense when the seller's corporate history creates unacceptable liability risk — ongoing litigation, environmental exposure, tax reassessments — that cannot be adequately mitigated through indemnities. Walking away from the seller's legal entity and buying only the clean assets may be the only way to limit your exposure.
How to Decide
The decision between asset and share purchase depends on multiple factors: your tax position, your tolerance for liability risk, the complexity of transferring contracts and permits, and whether key regulatory approvals or tax attributes need to be preserved.
Sellers typically prefer share sales to crystallize the Lifetime Capital Gains Exemption, which applies only to qualifying small business corporation shares, not asset sales. This creates a negotiation dynamic — you may prefer an asset purchase for tax and liability reasons, while the seller prefers a share sale for their own tax outcome. The resolution often involves a price adjustment, a blended structure (acquiring shares of a holding company that owns operating assets), or a section 85 tax-deferred rollover to balance tax outcomes between parties.
Start by listing the specific assets, contracts, permits, and liabilities at issue in your transaction. Identify which are difficult to transfer, which carry material unknown risk, and which have significant tax attributes. Then model the tax impact of each structure with your accountant and the liability exposure with your lawyer. The right structure is the one that aligns your tax outcome, risk tolerance, and deal complexity with the economic reality of what you're actually buying.
