Why This Matters

Incorporation is one of the most important tools for managing business risk. But it is not an absolute shield.

In real commercial disputes, plaintiffs often sue not only the corporation but also the owner, director, or officer personally. Even where the personal claim is ultimately dismissed, it can increase litigation costs, create settlement pressure, and expose individuals to stress involving personal assets, banking relationships, and credit.

This Insight explains common ways personal liability arises and the limits of those claims through two recent Ontario Court of Appeal decisions.

1. The Common Problem We See in Practice

A business relationship breaks down. Money is lost. A deal fails.

The plaintiff wants leverage and a better chance of collecting. So instead of suing only the corporation, the lawsuit also names the individuals behind it.

This commonly happens because:

• a personal guarantee was signed;
• an individual allegedly made a misleading statement;
• legislation imposes personal liability on directors or officers in specific situations;
• or the plaintiff alleges the corporation was used improperly as a shield for wrongful conduct (often called an attempt to “pierce the corporate veil”).

2. When Incorporation Did Not Protect the Individuals

BH Frontier Solutions Inc. v. 11054660 Canada Inc., (Canadian Choice Supply), 2024 ONCA 932

During the COVID-19 pandemic, a buyer entered into a large transaction for medical gloves through a distributor corporation. Significant funds were paid, but a substantial portion of the product was never delivered, and no refund followed.

The buyer alleged that the individuals behind the corporation made fraudulent misrepresentations that induced the transaction and the payments.

The Ontario Court of Appeal upheld the judgment finding the individuals personally liable alongside the corporation.

The Court accepted that a corporation cannot be used as a shield for conduct “akin to fraud,” including fraudulent misrepresentation, where the individuals were the directing minds controlling the company and using it to carry out the wrongdoing.

Bottom line

The business was incorporated, but the individuals were still personally liable because the claim was based on fraudulent misrepresentation, not merely corporate ownership.

3. When the Court Refused to Impose Personal Liability

1417217 Ontario Inc. v. River Trail Estates Inc., 2024 ONCA 491

This case involved a residential real estate joint venture that deteriorated into litigation over accounting issues, sale proceeds, and alleged misuse of corporate structures.

One individual was the sole shareholder and director of a corporation that held land for the venture. After the property was sold, the sale proceeds were redirected to another corporation instead of being paid into the joint venture structure.

At trial, the judge pierced the corporate veil and imposed personal liability on the individual.

The Ontario Court of Appeal reversed that decision.

The Court emphasized that:

• a corporation does not lose its separate legal identity merely because one person controls it;
• piercing the corporate veil is reserved for exceptional cases involving fraudulent or improper use of the corporation;
• and personal liability against directors or officers must be specifically pleaded and supported by distinct wrongful conduct.

The Court explained that even if a director may have improperly handled corporate funds, that alone does not automatically justify disregarding the corporation itself.

Bottom line

Control alone is not enough. Courts do not casually disregard incorporation merely because an individual owns or manages the corporation.

4. Why Personal Liability Claims Arise

Most personal-liability disputes are driven by predictable drafting and operational problems, including:

• guarantees signed without careful review;
• contracts or emails that fail to clearly identify the corporation as the contracting party;
• informal communications that later become the basis for misrepresentation claims;
• and blurred lines between personal and corporate dealings.

In litigation, plaintiffs often look for facts showing that the individual personally participated in the alleged wrongdoing rather than acting only through the corporation.

5. How Businesses Reduce the Risk

From a litigation perspective, prevention is mostly about clarity and discipline:

• Treat personal guarantees as separate negotiation items.
• Use proper signature blocks (for example, “ABC Inc., per: Name, Title”).
• Ensure contracts clearly identify the corporate party and define responsibilities and representations carefully.
• Avoid casual statements in texts and emails that could later be characterized as promises or representations.
• Maintain proper corporate separateness through bookkeeping, banking, approvals, and records.

Final Thought

Incorporation remains a meaningful protection when the corporation is properly maintained and not used for fraudulent or improper conduct.

But courts may still impose personal liability where individuals personally participate in wrongful acts, make fraudulent representations, sign guarantees, or blur the line between personal and corporate dealings.

In practice, many of these disputes are avoidable long before litigation begins, through careful drafting, disciplined corporate practices, and clear separation between the business and the individual behind it.
