Using a Trust in Business Succession Planning in Ontario

Building a successful private company is one thing. Handing control of it to the next generation without triggering a tax problem, a family fight, or both, is another challenge entirely. Many Ontario business owners assume their will alone can handle this — leave the shares to the kids, done. In practice, business succession usually benefits from planning that starts well before death, and a family trust is one of the tools most commonly used to do it properly.

This article explains, in general terms, how a trust in business succession planning typically fits into an Ontario private company transition, why timing matters so much, and where the limits of this planning tool are.

Why a Will Alone Often Isn't Enough

If you simply leave company shares to your children through your will, several practical problems commonly arise:

• Not all your children may be involved in the business. Splitting shares equally among children who are and aren't active in the company can create friction over control and compensation.
• The transfer happens all at once, at death, with no ability to gradually train, test, or transition management responsibility beforehand.
• The shares are deemed disposed of at fair market value immediately before death for tax purposes, which can trigger a significant, one-time tax liability at exactly the moment your family is least equipped to manage it.
• There's no built-in mechanism for what happens if a child who received shares later wants out, gets divorced, or has creditor problems.

A trust structured well before death addresses several of these issues by changing when, how, and to whom value in the company transfers — rather than leaving everything to happen in one lump-sum event on death.

How a Family Trust Is Typically Used

1. Separating growth from control

A common structure (often called an estate freeze, in general terms) has the current owner exchange their common shares for fixed-value preferred shares, while new common shares — which will carry future growth in the company's value — are issued to a family trust for the benefit of the next generation (children, grandchildren, or a combination). This lets the current owner "freeze" the value of their own interest while future growth accrues to the family trust for the benefit of the intended successors.

2. The trustee controls timing and allocation among beneficiaries

Because the trust (not the individual children) initially holds the growth shares, a trustee — often the current owner, along with independent trustees — retains control over how and when value is eventually allocated among the beneficiaries. This allows flexibility to reward the child who is actually running the business differently from a sibling who isn't involved, without having to decide those proportions irrevocably years in advance.

3. Gradual transition of control

Because the trust structure separates the timing of legal transfer from the timing of actual operational control, business owners can begin transitioning management responsibility to the next generation gradually, while formal share ownership questions are worked out over a longer runway.

Where a Primary and Secondary Will Fits In

Ontario estate planning for business owners often uses two separate wills — a "primary" will covering assets that require a Certificate of Appointment of Estate Trustee (probate), and a "secondary" will covering assets, such as private company shares, that generally do not require probate to transfer. This is a long-established and lawful Ontario planning technique, used because probate is calculated on the value of the estate that requires a certificate — keeping shares that don't need probate out of that calculation can reduce the portion of the estate exposed to Estate Administration Tax. This is a separate (though often complementary) tool to a family trust, and the two are frequently used together in a coordinated plan.

What This Kind of Planning Requires

Business succession trust planning is not a do-it-yourself project, and it isn't something that should be attempted through generic online templates. It typically involves:

1. A business valuation, to understand what is actually being frozen or transferred.
2. Coordinated legal and tax advice, since the corporate reorganization, the trust structure, and the wills all have to work together.
3. A shareholders' agreement addressing what happens if a family-member shareholder wants to sell, dies, becomes disabled, or divorces.
4. A family governance conversation, ideally well before any documents are signed, about who actually wants to run the business and how non-active children will be treated fairly.
5. Periodic review, since a structure that made sense when your children were in their twenties may not fit a decade later.

Common Pitfalls

• Waiting too long to start. This kind of planning benefits significantly from lead time — trying to do it in the final years before retirement, or after a health scare, sharply narrows the available options.
• Treating all children the same by default, without an honest conversation about who is actually involved in the business and who isn't.
• Skipping the shareholders' agreement, leaving no clear process for buyouts, disputes, or a family member who wants to exit.
• Not revisiting the plan. A trust and freeze structure set up once is not a "set it and forget it" arrangement — company value, family circumstances, and tax rules all change over time.
• Confusing this with simple estate planning. Business succession planning sits at the intersection of corporate law, tax, and estate planning, and generally needs input from more than one type of advisor.
