Tax Implications of Business Restructuring in Ontario: A Strategic Guide for 2026

At Insight Accounting CPA, we guide Mississauga and GTA business owners through complex restructuring transactions, ensuring tax efficiency while maintaining compliance with federal and provincial regulations.
Why Businesses Restructure
Corporate reorganization can serve multiple strategic purposes:
1. Operational Efficiency
Consolidating entities, eliminating redundant structures, or separating business lines for better management focus.
2. Succession Planning
Facilitating ownership transitions to family members or management teams while minimizing tax exposure.
3. Risk Management
Isolating liability by segregating high-risk operations into separate legal entities.
4. Pre-Sale Preparation
Optimizing corporate structure before a sale to maximize after-tax proceeds.
5. Estate Planning
Implementing estate freezes or trust structures to transfer wealth to the next generation.
Each restructuring type carries unique tax implications under the Income Tax Act, and careful planning is essential to avoid triggering unwanted tax liabilities.
Common Business Restructuring Scenarios
Amalgamations
When two or more corporations merge into a single entity, the Income Tax Act allows for tax-deferred treatment under section 87, provided certain conditions are met.
Tax Considerations:
- No immediate capital gains if structured correctly
- Losses and tax attributes may be carried forward subject to restrictions
- Continuity of tax basis in assets
- Potential for attribute loss if change in control occurs
Wind-Ups
Dissolving a subsidiary into a parent corporation can be done on a tax-deferred basis under section 88(1).
Requirements:
- Parent must own at least 90% of each class of shares
- Subsidiary must be a taxable Canadian corporation
- Wind-up must be completed within a specific timeframe
Benefits:
- Access to subsidiary’s losses (subject to restrictions)
- Simplified corporate structure
- Reduced compliance costs
Divisive Reorganizations (Butterfly Transactions)
Splitting a single corporation into two or more separate entities, often used when shareholders wish to pursue different business strategies.
Key Points:
- Requires advance CRA ruling for comfort
- Complex attribution rules apply
- Must meet “primarily for bona fide purposes” test
- Each entity must carry on active business post-split
Share-for-Share Exchanges
Exchanging shares of one corporation for shares of another can be structured on a tax-deferred basis under section 85.1.
Conditions:
- Acquiring corporation must be a taxable Canadian corporation
- Consideration must be solely shares
- No boot (non-share consideration) allowed
- Fair market value election typically required
Section 85 Rollovers: The Foundation of Tax-Deferred Restructuring
Section 85 allows shareholders to transfer property (including shares) to a corporation at an elected amount between cost and fair market value, deferring capital gains.
When to Use Section 85
- Asset protection: Moving business assets into a holding company
- Income splitting: Creating separate share classes for family members
- Estate planning: Implementing freezes while retaining control
- Pre-sale structuring: Separating real estate from operating assets
Key Requirements
Common Pitfalls
- Boot excess: Non-share consideration exceeding elected amount triggers immediate gain
- Attributed income: Income splitting arrangements may trigger attribution rules
- Related party transfers: Additional anti-avoidance rules apply
- Foreign property: Special rules for cross-border transfers
Estate Freezes: Locking in Value
An estate freeze allows business owners to cap the value of their shareholdings while transferring future growth to the next generation.
How Estate Freezes Work
Tax Benefits
- Freezes capital gains exposure at current value
- Facilitates use of lifetime capital gains exemption by next generation
- Income splitting opportunities through dividends on common shares
- Potential for multiplication of capital gains exemption
Important Considerations
- Immediate tax triggered if not structured correctly (section 86)
- Attribution rules may apply if children are minors
- TOSI (Tax on Split Income) rules for family members over 18
- Valuation critical – overvaluation can trigger tax immediately
Holding Company Structures
Interposing a holding company between operating entities and individual shareholders offers several advantages:
Tax Benefits
- Dividend refund mechanism: Eligible dividends paid from operating company to holding company receive refundable tax treatment
- Creditor protection: Isolates retained earnings from operating company liabilities
- Estate planning flexibility: Facilitates estate freeze implementation
- Capital gains deferral: Dividends paid to holding company avoid immediate personal tax
Ontario Tax Considerations
Ontario’s small business deduction requires careful planning when using holding companies to ensure active business income qualifies.
Active Business Test:
- Holding company cannot merely hold passive investments
- Must provide bona fide management services to operating companies
- Associated corporation rules limit total small business deduction to $500,000 across group
CRA General Anti-Avoidance Rule (GAAR)
The GAAR targets transactions that result in a tax benefit where one of the main purposes is to obtain that benefit, and the transaction is abusive.
GAAR Risk Factors in Restructuring
- Transactions structured solely for tax purposes without commercial substance
- Circular flows of funds with no economic purpose
- Aggressive interpretations of rollover provisions
- Butterfly reorganizations without genuine business purpose
Mitigating GAAR Risk
Change of Control Rules
When more than 50% of a corporation’s voting shares change hands, certain tax consequences are triggered:
Loss Utilization Restrictions
- Non-capital losses can only offset income from the same or similar business
- Net capital losses expire immediately
- Unused capital cost allowance may be restricted
Strategic Planning
- Time transactions to utilize losses before control changes
- Structure acquisitions to preserve loss carryforwards where possible
- Consider amalgamation vs. wind-up to maximize attribute preservation
Tax Due Diligence in Restructuring
Before executing any restructuring, comprehensive tax due diligence is essential:
Key Areas to Review
Common Issues Uncovered
- Underutilized tax attributes
- Timing mismatches between accrual and tax reporting
- Unreported shareholder loans subject to section 15(2)
- Non-arm’s length transactions triggering reassessment risk
Timeline and Documentation
Proper documentation is crucial for defending restructuring transactions during CRA review:
Essential Documentation
- Board resolutions approving the reorganization
- Share certificates evidencing transfers
- Section 85 elections filed within statutory deadlines
- Valuation reports supporting elected amounts
- Business purpose memoranda explaining commercial rationale
- Legal opinions confirming compliance with corporate and tax law
Timing Considerations
- Section 85 elections: Due the later of transferor’s tax return deadline or corporation’s first return
- Section 86 capital reorganizations: No formal election required, but restructuring must occur before year-end to benefit current tax year
- Section 88 wind-ups: Must be completed within prescribed timeframe to qualify for tax deferral
Provincial Considerations: Ontario Specifics
While corporate tax is federally governed, Ontario-specific considerations include:
Ontario Small Business Deduction
- Lower corporate tax rate (3.2%) on first $500,000 of active business income
- Associated corporation rules aggregate income across related entities
- Holding companies must meet active business tests
Land Transfer Tax
Restructurings involving Ontario real estate may trigger land transfer tax unless exemptions apply:
- Intra-group transfers: Exemption available for transfers between related corporations (90%+ common ownership)
- Section 85 rollovers: Generally exempt if properly structured
- Family farm exemptions: Special rules for agricultural properties
Ontario Employer Health Tax (EHT)
Corporate reorganizations can affect EHT exemptions:
- Each employer receives $1 million exemption
- Amalgamations consolidate exemptions
- Associated employers must share single exemption
Case Study: Multi-Entity Consolidation in Mississauga
Scenario:

- Potential land transfer tax exposure
Solution:
Our team at Insight Accounting CPA implemented a phased approach:
Result:
- Zero immediate tax triggered
- Simplified structure with single operating company and holding company

- Positioned for successful sale within 18 months
FAQ: Business Restructuring Tax in Ontario
Can I restructure my business without triggering immediate tax?
Yes, if properly structured using rollover provisions such as sections 85, 86, 87, or 88. These provisions allow tax-deferred transfers provided specific conditions are met. Professional guidance is essential to ensure compliance.
How do I know if my restructuring will attract CRA scrutiny?
Transactions that appear to lack commercial substance or are structured primarily for tax avoidance are high risk. Obtain advance tax rulings for complex reorganizations, document business purposes clearly, and work with experienced tax counsel to minimize GAAR concerns.
What happens to my company’s tax losses in a restructuring?
Loss preservation depends on the type of restructuring. Amalgamations and wind-ups generally preserve losses subject to restrictions. Change of control events can expire capital losses and restrict non-capital loss usage. Strategic planning can maximize loss utilization before restructuring.
Should I use a holding company structure?
Holding companies offer creditor protection, estate planning flexibility, and tax deferral benefits. They’re particularly valuable for businesses with retained earnings, multiple owners, or complex succession plans. However, they add compliance costs and require careful planning to maintain small business deduction eligibility in Ontario.
How long does a business restructuring take?
Timeline varies based on complexity. Simple section 85 rollovers can be completed within weeks, while multi-step reorganizations involving amalgamations, butterfly splits, or estate freezes may take 6-12 months including advance ruling applications and corporate formalities.
What are the costs of business restructuring?
Costs include legal fees for corporate reorganization, accounting fees for tax compliance and elections, valuation reports (typically $5,000-$15,000), and potential CRA advance ruling application fees ($2,000+). Total costs for comprehensive restructuring typically range from $15,000-$75,000 depending on complexity. The tax savings and risk mitigation typically far exceed these costs.
