Using a Corporate Reorganization to Protect an Ontario Estate

In Ontario, executing an “Estate Freeze” via a Section 86 corporate reorganization allows a business owner to lock in their current tax liability and pass all future company growth to their heirs. This strategy separates voting control from equity value, typically requiring $5,000 to $15,000 CAD in legal and accounting fees to set up correctly.

Passing down a successful family business is one of the greatest challenges in Ontario estate planning. If you own a thriving private corporation, the Canada Revenue Agency (CRA) will eventually demand capital gains taxes on the growth of those shares upon your death. Without proper planning, your heirs might be forced to liquidate the company just to pay the massive tax bill. To prevent this, successful business owners frequently utilize advanced wealth preservation strategies, the most powerful being the corporate reorganization known as an “Estate Freeze.”

An estate freeze, often executed using Section 86 of the Income Tax Act, is a brilliant maneuver. 📈 It effectively “freezes” the current value of your shares, fixing your final tax liability so you can plan for it with life insurance. Meanwhile, all future growth of the company is attributed to newly issued common shares held by your children or a family trust. Most importantly, whether your business is based in Toronto, Markham, or Waterloo, this legal structure allows you to retain absolute voting control of the company. You remain the boss, even as the future equity shifts to the next generation.

Step-by-Step Process for a Section 86 Share Exchange in Ontario

Undertaking a corporate reorganization is complex and requires absolute precision to avoid offside tax penalties from the CRA. Generally, you must work collaboratively with a corporate lawyer and a specialized tax accountant. Here is how the Section 86 estate freeze is typically executed in Ontario.

Step 1: Obtain an Independent Business Valuation

You cannot freeze a company without knowing its exact worth today. 💵 You must hire a Chartered Business Valuator (CBV) to assess the fair market value of your corporation. This valuation must be thoroughly documented, as the CRA may audit the numbers years later. If the valuation is too low, the CRA will penalize you for transferring wealth tax-free.

Step 2: Consult Your Corporate Lawyer and Accountant

Your advisory team will review the valuation and your family goals. They will design the share structure. Your accountant will confirm that the reorganization qualifies under Section 86 of the Income Tax Act, which allows you to exchange your shares on a tax-deferred “rollover” basis-meaning you do not pay capital gains tax on the day the reorganization happens.

Step 3: File Articles of Amendment

Your Ontario corporate lawyer will prepare the legal documents to change the structure of your company. 📝 They will file Articles of Amendment with the Ontario Business Registry. This step creates new classes of shares, typically “Fixed-Value Preference Shares” (which you will hold) and new “Common Shares” (which will hold the future growth).

Step 4: Execute the Share Exchange

The actual freeze occurs when you exchange all your existing common shares for the newly created Preference Shares. These Preference Shares have a fixed value exactly equal to the company’s worth today. Crucially, your lawyer will attach “voting rights” to these Preference Shares, allowing you to maintain full control over the board of directors and daily operations.

Step 5: Issue New Common Shares to a Family Trust

Instead of giving the new growth shares directly to your children (who might be minors, or might face future divorce or bankruptcy), a Family Trust is established. 👪 The corporation issues the new common shares to the trust for a nominal fee (e.g., $100 CAD). The trust holds the future growth for the benefit of your heirs, providing massive creditor protection. Note, however, that attempting to use a family trust for “dividend sprinkling” to children or spouses is restricted under the strict Tax on Split Income (TOSI) rules in Section 120.4 of the Income Tax Act. Any dividends paid to inactive family members will be taxed at the highest marginal rate (e.g., 53.53% in Ontario).

Step 6: Update the Unanimous Shareholder Agreement

Finally, your lawyer will draft a new Unanimous Shareholder Agreement (USA) and update the corporate minute book. This document governs what happens if a shareholder dies, becomes disabled, or attempts to sell their shares, ensuring the business stays securely within the family.

How Much Does an Estate Freeze Cost in Ontario?

An estate freeze is an elite B2B tax strategy. While the initial costs are significant, the ultimate tax savings for your estate can easily reach hundreds of thousands, or even millions, of dollars.

Service ProviderEstimated Cost (CAD)Details
Business Valuation (CBV)$3,000 – $10,000+Cost depends entirely on the size, industry, and complexity of your corporation.
Corporate Law Firm$5,000 – $15,000+Includes filing Articles of Amendment, executing the Section 86 rollover, and drafting the trust.
Tax Accountant (CPA)$3,000 – $7,000Tax planning, ensuring CRA compliance, and structured share exchange advising (note that Section 86 rollovers occur automatically without tax election forms).
Ontario Registry Fees$150 – $300Government fees to officially file the Articles of Amendment.

How Long Does the Process Take?

Executing a flawless corporate reorganization is a deliberate, multi-staged process. The longest phase is usually the initial valuation. A Certified Business Valuator generally requires 4 to 8 weeks to review your financials, interview management, and produce a formal valuation report.

Once the valuation is complete, the legal and tax execution moves relatively quickly. ⌛ Drafting the Articles of Amendment, the Family Trust, and finalizing the share exchange typically takes an additional 4 to 6 weeks. Overall, business owners in Ontario should expect the entire estate freeze process to take between 3 and 6 months from the initial meeting to the final signature.

Frequently Asked Questions (FAQ)

Do I lose control of my company if I do an estate freeze?

No. When structured correctly by a corporate lawyer, you exchange your old shares for new preferred shares that hold multiple voting rights. You remain entirely in control of all business decisions and can still pay yourself a salary and dividends.

What happens if the value of my company goes down after the freeze?

If the business struggles and loses value, you can perform a “thaw” or “refreeze.” Your lawyer and accountant can execute another reorganization to lower the fixed value of your preferred shares, matching the new, lower value of the company.

Why issue the new shares to a Family Trust instead of my kids?

Holding the new growth shares in a trust protects the assets. If your child gets divorced or goes bankrupt, the shares are shielded because the trust owns them, not the child directly. However, using a trust to shift dividend income to low-income family members is heavily restricted; under Section 120.4 of the Income Tax Act, the Tax on Split Income (TOSI) rules apply the highest personal tax rate (53.53% in Ontario) to dividends paid to inactive family beneficiaries.

When is the best time to do an estate freeze in Ontario?

Most professionals recommend considering an estate freeze when the business is highly profitable, rapidly growing, and the owner is in their 50s or 60s, transitioning toward retirement and actively planning their succession.
