Structural decisions, due diligence, key clauses, and closing mechanics for Ontario business acquisitions.
Buying or selling a business in Ontario involves one of the most consequential structural decisions in commercial law: asset deal or share deal? The choice affects tax exposure, liability allocation, HST treatment, employee obligations, and the scope of due diligence required. This guide walks through each stage of an Ontario business acquisition from term sheet to closing.
The fundamental question in every M&A transaction: does the buyer acquire the corporation's shares (buying the legal entity) or does the buyer acquire specific assets out of the corporation? Each structure has materially different implications.
| Factor | Asset Deal | Share Deal |
|---|---|---|
| What transfers | Chosen assets & assumed liabilities | Entire corporation (all assets & liabilities) |
| Historical liabilities | Generally excluded (buyer chooses) | Inherited with the company |
| Tax — buyer | Step-up in cost base; UCC on depreciables | No step-up; inherits existing tax attributes |
| Tax — seller (individual) | Business income on eligible assets; capital gains on goodwill | Capital gain; potential LCGE ($1.25M for 2025) |
| Third-party consents | Required for material contracts, leases, licences | Change-of-control clauses trigger consents |
| Employment | ESA successor employer rules; potential termination obligations | Employees continue with no break in service |
| HST | Section 167 election available if going-concern sale | No HST on share transfers |
| Land transfer tax | Applies to real property included in deal | Not triggered (shares, not land, transfer) |
| Complexity | More complex — schedule of assets, assignments | Simpler structure; more extensive due diligence |
| Preferred by | Buyers (cleaner slate) | Sellers (LCGE access, simplicity) |
2025 LCGE Update: The Lifetime Capital Gains Exemption for Qualified Small Business Corporation shares increased to $1.25M in 2025. This significantly enhances the tax advantage of a share sale for sellers who qualify — a major negotiating point in private M&A.
Scope due diligence to the deal structure and industry. Share deals require broader investigation because the buyer inherits all historical liabilities. Below is a comprehensive framework organized by category.
Sets the headline price and mechanisms for working-capital, cash, debt adjustments at closing
Practitioner tip: Define the Working Capital Target precisely — it is the most litigated post-closing adjustment in Ontario M&A.
Factual statements about the business that if false trigger indemnity
Practitioner tip: Qualify general reps with Material Adverse Effect and disclosure schedules; negotiate knowledge qualifiers carefully.
Pre-closing obligations (run in the ordinary course) and post-closing obligations (non-compete, non-solicit)
Practitioner tip: Ontario courts enforce non-competes if reasonable in time, geography, and scope — up to 24 months is generally defensible for business sales.
Events that must occur before either party is obligated to close (regulatory approvals, financing, no MAC)
Practitioner tip: Distinguish buyer conditions (waivable by buyer) from mutual conditions; include walk-away right if conditions not met by outside date.
Allocates post-closing risk for breaches of reps or undisclosed liabilities
Practitioner tip: Basket (deductible), cap, survival period, and escrow/holdback are all heavily negotiated; consider R&W insurance to de-risk.
Material Adverse Change/Effect — allows buyer to walk if something fundamental changes pre-closing
Practitioner tip: Post-SkyePharma litigation, MAC clauses have very high bars; be specific about what does/does not constitute a MAC.
Portion of purchase price held back to secure indemnity obligations
Practitioner tip: Typical holdback is 5-15% of purchase price for 12-24 months; R&W insurance can reduce or eliminate holdbacks.
Mechanism for resolving post-closing purchase price or indemnity disputes
Practitioner tip: Expert determination (an accountant) for working-capital disputes is faster and cheaper than arbitration or litigation.
Ontario business acquisitions typically close electronically (DocuSign or similar) with wire transfers. The closing agenda governs the sequence of deliveries and is coordinated by the buyer's lawyer.
In an asset purchase, the buyer acquires specific assets and liabilities of the business. In a share purchase, the buyer acquires the corporation itself, inheriting all historical liabilities. Asset deals offer buyers a clean start and allow cherry-picking assets; share deals are simpler structurally and may have tax advantages for sellers.
Due diligence covers: corporate records (minute books, shareholder agreements), financial statements (3 years), material contracts and their assignability, employment and union agreements, intellectual property, real property (owned or leased), environmental compliance, tax filings and assessments, pending litigation, and regulatory licences.
Simple asset deals may close in 30-60 days. Complex share deals with regulatory approvals (Competition Act, CRTC, etc.) often take 3-6 months. The timeline is driven by due diligence scope, financing requirements, landlord consents, and third-party regulatory clearances.
Negotiated survival periods are standard. Fundamental reps (title, authority, capitalization) typically survive indefinitely or for 6 years. General business reps often survive 12-24 months post-closing. Tax reps usually survive until the relevant limitation period expires plus a buffer. Parties may also use representation and warranty (R&W) insurance to extend or replace indemnity exposure.
