Introduction

Most owner-operated corporations have a single director: the owner. It is the simplest governance structure. It is also a structure that creates significant problems if that person dies unexpectedly, leaving a corporation with no living director to sign documents, authorise payments, file returns, or make decisions.

Scenario: Marco Dies Suddenly at 58

Marco is the sole shareholder and sole director of a profitable civil engineering consulting corporation. He is 58. His wife, Beatrice, is the designated beneficiary of his estate. Marco dies of a sudden cardiac event in November 2026.

The corporation has $840,000 in retained earnings, one ongoing project contract with $120,000 remaining to be billed, and two employees who are paid bi-weekly. A corporate bank account with $180,000 holds the operating funds.

The Immediate Problem: No Director

With Marco gone, the corporation has no director. The OBCA (Ontario Business Corporations Act) requires a corporation to have at least one director. With none, the corporation cannot:

Authorise transactions

Sign contracts or invoices

Authorise payroll (though the bank may continue pre-authorized payments)

File documents with the CRA

Make distributions

The corporation is effectively frozen from a governance perspective until a new director is appointed. Who appoints that director? Under the OBCA, shareholders can appoint directors — and Beatrice, as the estate's beneficiary and eventual shareholder (through probate), can act in that role once she has the legal authority to do so.

The gap period: Between Marco's death and the completion of probate (which can take months to over a year in Ontario), there is a governance vacuum. The estate trustee — who may be Beatrice, or an appointed executor — has the authority to manage the estate's assets, which includes the shares of the corporation. But converting estate authority into corporate governance authority requires the estate trustee to be recognised as the registered shareholder, which requires transmission of the shares through probate.

The Tax Obligations Do Not Pause

While the governance is being sorted out, the corporation's tax obligations continue on their normal schedule. The T2 for the fiscal year ending December 31, 2026 is due June 30, 2027. Payroll remittances for November and December 2026 are due on their normal remittance dates.

If remittances are missed because no one has authority to access the corporate account, the CRA does not waive the penalties for the governance disruption. Director liability for payroll remittances — which would normally attach to Marco — may now attach to the estate trustee who has effectively taken control of the corporation.

The Deemed Disposition

As discussed in Article 130, Marco's shares are deemed disposed of at fair market value at the date of his death. The terminal T1 return — due six months after the date of death, or April 30 of the following year, whichever is later — must report the deemed capital gain on the shares.

A business valuator will be required to determine the FMV of the shares. For a corporation with $840,000 in retained earnings, the shares have significant value. If Beatrice receives the shares (through the estate), the spousal rollover defers the deemed gain. If the shares pass to children or other beneficiaries, the gain is immediately taxable in the terminal return.

The Project Contract Problem

Marco's corporation has an ongoing contract with $120,000 remaining. With no active director, who can invoice the client? Who can supervise the work? The employees are still present but have no authorised management structure.

In practice, the estate trustee may engage an interim manager or consulting engineer to complete the project while the governance transition is completed. The cost of this arrangement is a corporate expense — deductible against the corporate income from the project completion.

What Would Have Prevented This

A corporate governance plan that addresses director succession in the event of death:

A co-director nominated in advance (Beatrice, an adult child, or a trusted professional associate) who can assume the director role immediately without waiting for probate.

A well-drafted will that specifically addresses the shares and the corporate governance gap.

A shareholders agreement with provisions for estate trustee governance authority.

Corporate-owned life insurance, sized to cover the deemed disposition tax on the shares, providing the estate with liquidity to pay the terminal return tax without liquidating corporate assets.

When to Speak With a CPA

For any sole-director corporation, a CPA review of the governance and estate plan — focused on the corporate consequences of the director's death — is a planning conversation worth having at any age. The cost of preparing a corporate succession plan is trivial compared to the cost of a governance vacuum at the worst possible moment.
