What Is a Share Sale Transaction?

A share sale transaction is the sale of the shares of a corporation from its existing shareholders to a buyer. When the shares change hands, the corporation itself continues to exist as a legal entity, only its ownership changes. The buyer steps into the seller's position and acquires everything the corporation owns: assets, contracts, intellectual property, licences, and every liability, known or unknown.

This is the fundamental distinction between a share sale and an asset sale. In a share sale, the buyer purchases a single thing, the shares, and the "corporate wrapper" transfers intact. In an asset sale, the buyer selects specific assets to acquire and leaves the existing corporation (and most of its liabilities) behind with the seller.

Share sales are often the preferred structure when a business has licences, permits, customer contracts, or leases that are either non-assignable or expensive to transfer. They are also the only route to the Lifetime Capital Gains Exemption for sellers of Qualified Small Business Corporation Shares, a potential tax saving of hundreds of thousands of dollars for eligible Canadian business owners.

Ontario-incorporated corporations are governed by the Ontario Business Corporations Act (OBCA), and federally incorporated corporations are governed by the Canada Business Corporations Act (CBCA). Both statutes regulate how shares are issued, transferred, and recorded, and your Toronto share sale transactions lawyer will work within the correct framework depending on the target corporation's jurisdiction.

Share Sale vs. Asset Sale: Choosing the Right Structure in Ontario

The choice between a share sale and an asset sale shapes the tax outcome, the risk allocation, and the paperwork required to close. We advise clients on this decision before they are locked into a structure, because renegotiating later is expensive and often impossible.

Why Sellers Often Prefer a Share Sale

Tax treatment. Proceeds from a share sale are generally taxed as capital gains. If the shares qualify as Qualified Small Business Corporation Shares, the seller may be able to shelter up to $1.25 million of gains using the Lifetime Capital Gains Exemption.
No HST on the sale price. HST generally does not apply to the sale of shares, because shares qualify as a financial service exempt under the Excise Tax Act. By contrast, asset sales can trigger HST on certain assets unless the parties make a valid joint election.
Contract and licence continuity. The corporation keeps its contracts, leases, and licences. There is no need to renegotiate with customers, suppliers, or landlords, which helps preserve goodwill and momentum.
Simpler closing mechanics. One asset changes hands: the shares. There is no long list of individual assets to transfer or retitle.

Why Buyers Often Prefer an Asset Sale

Liability protection. The buyer acquires specific assets and leaves unwanted liabilities, historical lawsuits, CRA exposure, unknown contingent obligations, with the seller.
Selective acquisition. The buyer chooses which employees, contracts, and assets to take.
Stepped-up cost base. The buyer can often depreciate acquired assets from their fair market value, which improves after-tax economics.

When a Hybrid Structure Makes Sense

Some deals combine elements of both, a share purchase paired with carved-out assets, specific indemnities for legacy liabilities, or a pre-closing reorganization to separate unwanted assets from the target corporation. Our lawyers structure deals to balance the seller's tax efficiency against the buyer's risk tolerance.

The Share Sale Transaction Process: Step by Step

Every transaction is different, but most private-company share sales follow a predictable sequence. Understanding what is coming helps you prepare and negotiate from a position of confidence.

Preliminary valuation and business assessment, Before the market knows a deal is coming, the seller should have a defensible valuation, a clean minute book, and a clear picture of any shareholder agreement restrictions that may affect the transfer (right of first refusal, pre-emptive rights, drag-along or tag-along provisions, transfer restrictions).
Letter of intent (LOI), A non-binding document that sets out the headline terms: price, structure, exclusivity period, timeline, and major conditions. Critically, even a "non-binding" LOI typically contains binding provisions, confidentiality, no-shop, and expense allocation. These clauses survive even if the deal collapses.
Due diligence, The buyer investigates the corporation's financial, legal, tax, and operational health. This is where hidden liabilities surface and purchase price adjustments are negotiated.
Negotiating and drafting the share purchase agreement (SPA), The central transaction document. The buyer's lawyer typically drafts first; the seller's lawyer negotiates representations, warranties, indemnification limits, and conditions precedent.
Closing, Simultaneous exchange of signed documents, payment of the purchase price (less any holdbacks), update of the share register and corporate records, and resignation of the outgoing directors and officers.
Post-closing obligations, Corporate filings with ServiceOntario or Corporations Canada, tax reporting, and ongoing seller obligations such as non-compete or non-solicitation covenants.

Having an experienced Toronto share sale transactions lawyer through every step of this process helps protect your interests when the stakes are highest. Call (437) 974-2374 to discuss your transaction.

The Share Purchase Agreement: Key Provisions

The share purchase agreement is the document that governs the entire transaction. A well-drafted SPA anticipates problems before they happen and allocates risk clearly between buyer and seller.

Parties, Definitions, and Defined Terms

Every SPA opens by identifying the parties, buyer, seller, any guarantors, and sometimes the target corporation itself. Defined terms such as "Closing Date," "Material Adverse Effect," and "Knowledge of the Seller" appear throughout the agreement and must be drafted precisely, because they control how other clauses operate.

Purchase Price and Payment Terms

The price is rarely a single fixed number paid in full at closing. Most deals involve a working capital adjustment, a holdback (a portion of the price held back to cover warranty claims), and often an earnout tied to post-closing performance. The SPA must spell out how each component is calculated, when it is paid, and who bears the risk if calculations go wrong.

Representations and Warranties

The seller makes detailed statements about the corporation, that financial statements are accurate, taxes are paid, material contracts are in good standing, there is no undisclosed litigation, and much more. These representations give the buyer a right to claim damages if any prove false. Representations and warranties commonly survive 18 to 24 months after closing, though this period is heavily negotiated.

Covenants

Covenants are promises about conduct. Pre-closing, the seller commits to running the business in the ordinary course and not to enter major new contracts without the buyer's consent. Post-closing, the seller often agrees to non-compete and non-solicitation covenants to protect the goodwill the buyer has paid for.

Conditions Precedent

Nothing happens at closing unless the conditions precedent are satisfied. Typical conditions include regulatory approvals (for example, Competition Act pre-merger notification for larger transactions, a filing that applies when the transaction-size and party-size thresholds under the Competition Act are met), third-party consents, financing, and completion of due diligence without the discovery of a material adverse issue.

Indemnification

If a representation turns out to be wrong, who pays? Indemnification clauses answer this, subject to deductibles (small claims are absorbed), caps on total liability, and time limits on when claims can be brought. Negotiating these limits is one of the most contentious parts of an SPA.

Dispute Resolution and Termination

The SPA should be governed by Ontario law, with disputes resolved in the Ontario Superior Court of Justice or through arbitration under the Arbitration Act, 1991. Termination clauses set out when either party can walk away before closing, for example, on material breach or failure of a condition precedent.

Tax Considerations in a Share Sale Transaction

Tax drives many share sale decisions. Our Tax Lawyer, Martina Caunedo, brings over 12 years of international tax experience to the firm and works alongside our corporate lawyers to integrate tax planning into deal structuring, rather than treating it as an afterthought.

Capital Gains Treatment

Proceeds from a share sale are generally taxed as capital gains, with the inclusion rate determined by federal tax rules. The precise inclusion rate and thresholds continue to evolve at the federal level, and we monitor those changes for our clients.

The Lifetime Capital Gains Exemption

For many Canadian business owners, the Lifetime Capital Gains Exemption (LCGE) is the single most valuable tax planning opportunity they will ever encounter. For dispositions after June 24, 2024, the LCGE on Qualified Small Business Corporation Shares was increased to $1.25 million, and the exemption is indexed to inflation starting in 2026.

To qualify as Qualified Small Business Corporation Shares, three core tests must be met:

Small Business Corporation test at the time of sale. At the moment of sale, the shares must be of a Small Business Corporation owned by the individual, a spouse, or a related partnership.
24-month holding period. Throughout the 24 months immediately before the sale, the shares must have been owned by the individual (or a related party), and the corporation must have been a Canadian-Controlled Private Corporation (CCPC).
24-month active business asset test. During that same 24-month period, more than 50 percent of the fair market value of the corporation's assets must have been used principally in an active business carried on in Canada.

Sellers who discover shortly before closing that they fail one of these tests can sometimes be restructured into qualification, but only with enough runway. Early legal and tax advice is essential.

The Canadian Entrepreneurs' Incentive

Introduced in the 2024 federal budget, the Canadian Entrepreneurs' Incentive (CEI) reduces the capital gains inclusion rate to one-third on eligible capital gains, up to a lifetime maximum of $2 million when fully phased in. The annual limit is phased in at $400,000 in 2025, $800,000 in 2026, $1.2 million in 2027, $1.6 million in 2028, and reaches $2 million in 2029. Combined with the LCGE, eligible founders may be able to shelter meaningful additional gains on highly advantageous terms.

HST on Share Sales

Unlike asset sales, share sales generally do not attract HST on the purchase price, because the sale of shares is treated as a financial service exempt under the Excise Tax Act. This is a meaningful cash-flow advantage and one of the reasons sellers frequently push for a share deal.

Buyer's Tax Considerations

Buyers inherit the corporation's tax history and cost base. There is no automatic step-up of asset values to fair market value as there would be in an asset sale, which can affect future depreciation and the timing of tax deductions. We help buyers model these outcomes and, where appropriate, negotiate purchase price adjustments that reflect the tax mismatch.

Due Diligence in Share Purchase Transactions

Due diligence matters more in a share sale than almost any other transaction, because the buyer assumes every liability, including the ones nobody knew existed. Our team conducts due diligence designed around the specific industry, regulatory environment, and deal size, rather than running a template checklist.

Financial Due Diligence

Three to five years of financial statements (audited or reviewed where available), tax returns, bank statements, accounts receivable and payable aging, inventory records, capital expenditure history, and every outstanding debt and guarantee. The goal is to understand true earnings power and working capital requirements, not just to read numbers.

Legal Due Diligence

Corporate records. Articles, by-laws, minute book, share register, director and officer registers, resolutions of the board and shareholders.
Material contracts. Customer and supplier agreements, leases, licences, partnership agreements, NDAs, and any agreement with a change-of-control clause that could trigger on the sale.
Employment. Employment agreements, independent contractor arrangements, compensation plans, and termination obligations under the Employment Standards Act, 2000 and common law.
Litigation and regulatory. Pending or threatened litigation, regulatory investigations, outstanding judgments, and any orders affecting the corporation.
Tax. CRA assessment history, HST and payroll source deduction compliance, and the status of any audit or objection.

Corporate Searches

A complete due diligence file includes Personal Property Security Act (PPSA) searches, Bank Act searches, execution searches, and an Ontario corporate profile confirming good standing. These searches identify registered security interests, secured creditors, and unsatisfied judgments, all of which can affect whether the deal closes, at what price, and on what terms.

Common Deal-Killers and Price Adjusters

Undisclosed CRA assessments, material contracts with change-of-control clauses the seller cannot get waived, employee termination obligations that exceed what the seller represented, and environmental liabilities in regulated industries. When these surface, experienced counsel negotiates price reductions, indemnity carve-outs, or escrow arrangements rather than letting the deal collapse.

For cross-border and international transactions, our ability to conduct business in English, French, Spanish, and Catalan means we can communicate directly with parties across North America, Europe, Africa, and Latin America, without the delays, cost, and miscommunication risks of working through translators.

Cross-Border Transactions and the Investment Canada Act

When a foreign buyer acquires shares of a Canadian corporation, the Investment Canada Act may require either a notification or a formal review, depending on the size of the transaction and the industry involved. Nassira El Hadri, our Founder & Principal Lawyer, handles Investment Canada Act filings and advises on the cross-border elements that make international share sales more complex than their domestic counterparts.

Frequently Asked Questions About Share Sale Transactions

How long does a share sale transaction take in Ontario?

Most private-company share sales in Ontario close within four to twelve weeks of a signed letter of intent. Complex transactions, large deal sizes, regulated industries, cross-border elements, or Competition Act pre-merger filings, can extend the timeline to several months. Clean corporate records and responsive parties tend to shorten it meaningfully.

Do I need a lawyer to complete a share purchase in Ontario?

You are not legally required to retain counsel, but proceeding without a lawyer on a share purchase is risky. A lawyer helps ensure the representations, warranties, and indemnities are comprehensive, that due diligence uncovers the real issues, and that the agreement is enforceable. Without legal advice, buyers often assume unknown liabilities and sellers often jeopardize their tax position.

What is a holdback in a share purchase agreement?

A holdback is a portion of the purchase price, commonly 10 to 15 percent, withheld at closing and released after a set period, usually 12 to 18 months. It gives the buyer a ready source of funds to satisfy warranty claims that surface post-closing. Holdbacks are often held in escrow by a neutral third party.

Can a shareholder agreement restrict a share sale?

Yes. A shareholder agreement may include rights of first refusal, pre-emptive rights, drag-along or tag-along clauses, restrictions on transfers to competitors, or outright consent requirements. These provisions must be reviewed before the sale process begins, ignoring them can unwind a deal or expose the seller to damages claims from co-shareholders.

What taxes does a seller pay when selling shares of a corporation?

Sellers generally pay tax on capital gains realized on the sale. If the shares qualify as Qualified Small Business Corporation Shares, the seller may be able to shelter up to $1.25 million of gains using the Lifetime Capital Gains Exemption. HST does not apply to the sale of shares, though other tax considerations, such as the CEI, may further reduce the tax burden for eligible entrepreneurs.

What happens to employees when shares are sold?

In a share sale, the corporation continues to be the employer, the legal entity is unchanged. Existing employment agreements, accrued vacation, and service-based entitlements carry over in full; there is no termination or rehiring. This is fundamentally different from an asset sale, where the buyer chooses which employees to hire. The continuity makes share sales simpler for workforces but increases buyer responsibility for pre-closing employment liabilities.
