Share Purchase Agreement Canada: Complete Guide & Template 2026
Buying or selling shares in a Canadian corporation is a significant transaction requiring careful legal documentation. A share purchase agreement (SPA) protects both buyers and sellers by clearly defining the terms of the share transfer. This guide explains everything Canadian business owners need to know about share purchase agreements.
What is a Share Purchase Agreement?
A share purchase agreement is a legal contract governing the sale of shares in a corporation from one party (the seller) to another (the buyer). Unlike an asset purchase where specific business assets are sold, a share purchase transfers ownership of the corporation itself, including all its assets, liabilities, contracts, and obligations.
SPAs are commonly used when:
- Selling an entire business to a new owner
- Bringing in new shareholders or investors
- Buying out existing shareholders
- Transferring shares between family members
- Facilitating mergers and acquisitions
Share Purchase vs Asset Purchase in Canada
Understanding the difference between these two transaction structures is crucial for making the right choice:
Share Purchase
- Buyer acquires shares of the corporation
- Corporation continues with all existing contracts, licenses, and obligations
- All liabilities (known and unknown) transfer with shares
- Generally more favorable tax treatment for sellers
- Simpler transfer process for ongoing businesses
Asset Purchase
- Buyer acquires specific assets of the business
- Contracts and licenses may need reassignment
- Buyer can exclude unwanted liabilities
- Generally more favorable for buyers (cherry-pick assets)
- May trigger more immediate tax consequences

Key Components of a Share Purchase Agreement
A well-drafted SPA includes these essential elements:
Parties and Recitals

- Cash payment at closing
- Installment payments via promissory note
- Earnout provisions tied to future performance
- Escrow arrangements for holdback amounts

Representations and Warranties

- Status of material contracts
- Intellectual property ownership

Conditions Precedent
Events or circumstances that must occur before closing, such as:
- Satisfactory completion of due diligence
- Obtaining necessary consents and approvals

Details the mechanics of completing the transaction, including:
- Closing date and location

Due Diligence in Share Purchases
Because share purchases transfer all corporate liabilities, thorough due diligence is essential. Buyers should investigate:
Legal Due Diligence
- Corporate minute books and share registers
- Articles of incorporation and bylaws
- Shareholder agreements
- Material contracts and obligations
- Pending or threatened litigation
- Intellectual property registrations

Tax Implications of Share Sales in Canada
Share transactions have significant tax consequences for both parties:
For Sellers
- Capital gains: Proceeds minus adjusted cost base creates capital gain (50% taxable)
- Lifetime Capital Gains Exemption: Qualified small business corporation shares may qualify for up to $1,016,836 (2024) exemption
- Section 85 rollover: May defer gains when transferring to a corporation
For Buyers
- Purchase price becomes adjusted cost base of shares
- No immediate tax deduction (unlike asset purchases)
- Corporation retains existing tax attributes
Professional Advice
Given the complexity of tax planning in share transactions, both parties should consult accountants and tax lawyers before finalizing the deal structure.
Share Certificates and Transfer
The mechanics of transferring shares require proper documentation:
- Share certificates: Physical certificates (if issued) must be endorsed and delivered
- Share transfer form: Documents the transfer in corporate records
- Directors’ resolution: Approves the share transfer
- Updated share register: Reflects new ownership
- New share certificates: Issued to buyer

Common Issues in Share Purchase Agreements
Watch for these potential problems when negotiating an SPA:
Undisclosed Liabilities
Buyers inherit all corporate liabilities, including those not disclosed. Strong representations, warranties, and indemnification provisions are essential protection.
Change of Control Provisions
Material contracts may contain provisions triggered by share sales, potentially allowing counterparties to terminate. Review all key contracts for change of control language.
Employee Matters
Share purchases don’t automatically trigger employment law issues since the employer (corporation) remains unchanged. However, key employees may have change of control clauses in their contracts.
Purchase Price Disputes
Earnouts and working capital adjustments frequently lead to post-closing disputes. Clear definitions and dispute resolution mechanisms are critical.
