Most people who have never been through a business acquisition assume it is simple: agree on a price, sign some papers, hand over the keys. In practice, buying or selling a small business in Canada is a structured legal process that typically spans 60 to 90 days, involves a series of documents and decision points, and contains at least one choice — the asset versus share purchase question — that can mean a difference of hundreds of thousands of dollars in after-tax proceeds for the seller. Here is what the process actually looks like, from start to close.
Step 1 — The Letter of Intent (LOI)
Before formal legal work begins, the buyer and seller typically sign a Letter of Intent (LOI), sometimes called a term sheet or heads of agreement. The LOI sets out the key commercial terms: purchase price, structure of the transaction, what assets or shares are included and excluded, a timeline for due diligence and closing, and any material conditions.
Most LOIs are expressly non-binding on the substantive terms, except for specific provisions: confidentiality (protecting the sensitive information the seller will share during due diligence), exclusivity (preventing the seller from negotiating with other buyers during a defined window), and sometimes a break fee triggered if the buyer walks away without cause.
The LOI matters more than most people realize. The commercial terms agreed at the LOI stage — structure, price adjustments, exclusions, conditions — shape the entire negotiation that follows. Errors or ambiguities in the LOI become the foundation of disputes in the formal documentation. Investing legal time at the LOI stage consistently results in a faster, lower-cost closing.
Step 2 — Due Diligence
Due diligence is the buyer's formal investigation of the business. A comprehensive due diligence process covers financial records (typically three years of financial statements, tax returns, and management accounts), commercial contracts (customer agreements, supplier agreements, leases, software licenses), employment and HR records, corporate records (the minute book, share certificates, directors and shareholders resolutions, regulatory filings), intellectual property (ownership, registration, assignments), and any outstanding or threatened litigation or regulatory proceedings.
From a seller's perspective, due diligence is where problems surface. The issues that most frequently slow or derail transactions include: disorganized or incomplete corporate minute books, commercial contracts containing change-of-control provisions that require third-party consent to assign, undisclosed or contingent liabilities, intellectual property developed by contractors without proper written IP assignment agreements, and employment records that do not comply with applicable standards.
Sellers who maintain organized corporate records, current minute books, and properly documented contracts move through due diligence faster, with fewer surprises, and with meaningfully better outcomes. Buyers who find clean records gain confidence in the business; buyers who find disorder discount accordingly.
Step 3 — Asset Purchase vs. Share Purchase
This is the most consequential structural decision in any Canadian business acquisition, and buyers and sellers typically approach it from opposite directions.
In a share purchase, the buyer acquires the shares of the target corporation. The corporation — with all of its assets, contracts, employees, liabilities, and history — transfers to the buyer intact. The buyer inherits the business as a going concern, including any liabilities that were not disclosed or not identified in due diligence.
In an asset purchase, the buyer acquires specified assets of the business — typically goodwill, customer lists, equipment, intellectual property, and the right to assume certain contracts — and assumes only those liabilities expressly agreed to. The target corporation remains with the seller, along with its history and any liabilities not transferred. The buyer starts with a clean entity.
From a tax perspective, sellers strongly prefer share purchases. The sale of shares of a Qualifying Small Business Corporation (QSBC) as defined under the Income Tax Act may be eligible for the Lifetime Capital Gains Exemption (LCGE), which in 2024 shelters over $1,000,000 of capital gains per individual shareholder from federal income tax. This exemption is available only on the sale of qualifying shares — not on the sale of assets. For a seller with two shareholders, both eligible for the LCGE, the difference in after-tax proceeds between a share sale and an asset sale can be substantial.
From a buyer's perspective, asset purchases are often preferable for the opposite reason: the buyer does not inherit unknown liabilities, and the buyer typically obtains a higher tax cost base on the acquired assets, generating better capital cost allowance deductions going forward. In most small business transactions, the final structure reflects a negotiated compromise, with the purchase price adjusted to account for the tax consequences of the agreed approach.
Step 4 — The Purchase Agreement
The definitive purchase agreement — whether an Asset Purchase Agreement (APA) or Share Purchase Agreement (SPA) — is the binding contract that governs the transaction. The key components are:
Purchase price and adjustments. The headline price is rarely the final price. Working capital adjustments, inventory adjustments, and pre-closing distributions are common mechanisms for aligning the economic reality of the business at closing with the price agreed at signing. These adjustments are calculated against an agreed target and trued up post-closing.
Representations and warranties. The seller makes binding representations about the state of the business — that the financial statements accurately reflect the company's financial position, that there are no undisclosed liabilities, that all material contracts are valid and in good standing, that employees are properly documented, and that the company owns the IP it uses. If any representation proves to be false, the buyer has a claim for breach.
Indemnification. The seller agrees to indemnify the buyer for losses arising from breaches of representations and warranties, subject to negotiated limits: a basket (minimum threshold before claims are actionable), a cap (maximum exposure), and survival periods (how long after closing claims can be brought). These provisions are among the most heavily negotiated in any purchase agreement and directly affect the seller's risk exposure after the deal closes.
Non-competition. The seller typically agrees not to compete with the acquired business for a defined period and within a defined geography following closing. Canadian courts will enforce reasonable non-competition covenants; provisions that are excessive in duration, geography, or scope are at risk of being set aside or read down by the court. Reasonable, in the context of a business sale, is more permissive than in an employment context.
Step 5 — Closing
Closing is the day the transaction completes. Share certificates or asset transfer documents are delivered, the purchase price is paid — sometimes in a single payment, sometimes in tranches with a portion held in escrow to secure indemnification obligations — and the parties exchange the closing deliverables required by the purchase agreement. These typically include officer certificates, directors' resolutions approving the transaction, resignations of the existing directors and officers, and regulatory filings.
Post-closing, there is usually a working capital adjustment period during which the parties calculate the actual working capital of the business as of the closing date and compare it against the agreed target. The purchase price is adjusted up or down accordingly. This process typically takes 30 to 60 days after closing and is one of the most common sources of post-closing disputes in small business transactions. A clearly drafted adjustment mechanism in the purchase agreement reduces that risk significantly.
Common Deal-Killers
The issues that most frequently derail deals or materially reduce the seller's proceeds are:
- Disorganized corporate records. Missing resolutions, unsigned share certificates, and gaps in the minute book create title problems that either delay the deal, reduce the purchase price, or require expensive remediation before closing can occur.
- Undisclosed liabilities. Buyers reprice aggressively — or walk away entirely — when due diligence surfaces liabilities that were not disclosed at the LOI stage.
- Change-of-control provisions. Customer contracts and commercial leases frequently contain provisions requiring counterparty consent on a change of control or assignment. If a key contract cannot be assigned without consent and that consent cannot be obtained, the deal's economics change fundamentally.
- IP ownership problems. Software, tools, and content developed by contractors without a written IP assignment agreement do not belong to the corporation. In any business where IP is a core asset, unresolved ownership is a deal-stopper discovered in due diligence and expensive to fix retroactively.
The Bottom Line
Buying or selling a small business in Canada is a multi-step process with significant legal and tax implications at each stage. The asset versus share purchase decision alone can be worth hundreds of thousands of dollars to the seller. Getting the representations and warranties wrong can mean years of post-closing disputes. Good legal counsel on a transaction does not just mean drafting documents — it means structuring the deal to protect your interests at every stage, from the LOI to the post-closing adjustment.
