Buying or Selling a Small Business in Canada: What the Legal Process Actually Looks Like

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.

Step 1 — The Letter of Intent (LOI)

Before formal legal work begins, the buyer and seller typically sign a Letter of Intent (LOI). 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 substantive terms, except for confidentiality, exclusivity, and sometimes a break fee.

The LOI matters more than most people realize. The commercial terms agreed at the LOI stage shape the entire negotiation that follows. 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 process covers financial records, commercial contracts, employment and HR records, corporate records, intellectual property, and any outstanding litigation or regulatory proceedings.

The issues that most frequently slow or derail transactions include: disorganized corporate minute books, contracts containing change-of-control provisions, undisclosed liabilities, IP developed by contractors without assignment agreements, and non-compliant employment records.

Step 3 — Asset Purchase vs. Share Purchase

This is the most consequential structural decision in any Canadian business acquisition. In a share purchase, the buyer acquires the shares of the target corporation with all assets, contracts, employees, and liabilities. In an asset purchase, the buyer acquires specified assets and assumes only those liabilities expressly agreed to.

Sellers strongly prefer share purchases. The sale of shares of a Qualifying Small Business Corporation (QSBC) may be eligible for the Lifetime Capital Gains Exemption (LCGE), which shelters over $1,000,000 of capital gains per individual shareholder from federal income tax. This exemption is only available on share sales — not asset sales. For a seller with two shareholders, both eligible for the LCGE, the difference in after-tax proceeds can be substantial.

Buyers prefer asset purchases because they don't inherit unknown liabilities and typically obtain a higher tax cost base on acquired assets. In most transactions, the final structure reflects a negotiated compromise.

Step 4 — The Purchase Agreement

The definitive purchase agreement — whether an Asset Purchase Agreement (APA) or Share Purchase Agreement (SPA) — covers: purchase price and adjustments (working capital, inventory, pre-closing distributions), representations and warranties (binding statements about the state of the business), indemnification (baskets, caps, survival periods), and non-competition covenants.

Step 5 — Closing

Closing is the day the transaction completes. Share certificates or asset transfer documents are delivered, the purchase price is paid, and the parties exchange closing deliverables. Post-closing, there is usually a working capital adjustment period of 30 to 60 days — one of the most common sources of post-closing disputes.

Common Deal-Killers

• Disorganized corporate records — missing resolutions, unsigned share certificates, gaps in the minute book

• Undisclosed liabilities — buyers reprice aggressively or walk away entirely

• Change-of-control provisions — key contracts that cannot be assigned without consent

• IP ownership problems — software developed by contractors without written IP assignment agreements

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. Good legal counsel on a transaction means structuring the deal to protect your interests at every stage, from the LOI to the post-closing adjustment.
