Can I Be Personally Liable for My Corporation's Debts?

The short answer

Usually no, but directors, and in Alberta certain shareholders, can still end up personally on the hook. Incorporating a business is meant to separate the company’s debts from your personal finances. Federally, the Canada Business Corporations Act (CBCA) states directly that shareholders “are not, as shareholders, liable for any liability, act or default of the corporation,” except under a short list of named sections (CBCA, RSC 1985, c C-44, s 45(1)). That is the starting point in every Canadian jurisdiction covered here. The exceptions, however, are where founders get caught, and they fall into two very different categories: statutory director liability (federal and Ontario), and Alberta’s unlimited liability corporation structure, where the shield does not exist for shareholders at all.

When directors become liable for unpaid wages

The most common source of personal liability is not shareholder status, it is holding the office of director while the corporation fails to pay its workforce. Both the federal and Ontario regimes single out unpaid wages as an exception to limited liability, though the numbers differ:

The federal provision makes directors “jointly and severally, or solidarily, liable to employees of the corporation for all debts not exceeding six months wages payable to each such employee for services performed for the corporation while they are such directors” (CBCA s 119(1)). Ontario’s Business Corporations Act imposes a parallel obligation: “Directors of a corporation are jointly and severally liable to the employees of the corporation for all debts not exceeding 6 months’ wages and up to 12 months’ vacation pay” (OBCA s 131, as summarized by the Government of Ontario). In both cases, the liability attaches to the person who held office as director while the wages were earned, not to shareholders generally.

Other statutory liabilities directors face

Wages are not the only exposure. Corporations Canada’s own guidance on the CBCA confirms that “in certain circumstances, directors are liable for up to six months’ worth of unpaid wages to employees of the corporation, as well as for any unpaid source deductions” (payroll withholdings such as income tax, CPP, and EI remitted to the government). Ontario’s guidance on director liability goes further, flagging that directors “may also be liable under Federal and other provincial statutes (for example, Income Tax Act, Employment Standards Act and environmental statutes)” beyond the Business Corporations Act itself. In other words, the OBCA’s wage and vacation-pay rule is a floor, not the full picture: directors weighing their exposure need to look at tax and employment legislation as separate, additional sources of liability, not just the corporate statute.

Alberta’s unlimited liability corporation: the exception to the exception

Alberta has a structure that does not exist federally or in Ontario: the unlimited liability corporation (ULC). The Alberta Business Corporations Act defines a ULC as “a corporation whose shareholders have unlimited liability for any liability, act or default of the corporation” (ABCA, RSA 2000, c B-9, s 1(kk)). Choosing (or being required by a parent company’s tax planning) to incorporate as a ULC means the general shareholder shield simply does not apply; shareholders can be pursued directly for the corporation’s debts.

That exposure does not necessarily end when the company is wound up. Under section 15.7 of the Alberta Business Corporations Act, “the liability of the shareholders for obligations of the unlimited liability corporation arising from actions and proceedings commenced by or against it before its dissolution or within 2 years after its dissolution is unlimited,” and this can extend to shareholders who left the company within two years before dissolution. For anyone considering an Alberta ULC, whether as an original shareholder or a purchaser of shares, this two-year tail is a distinct feature that does not appear in the federal or Ontario regimes covered here.

What this means in practice

Putting the pieces together: the corporate veil (the legal separation between a company and the people who own or run it) is the default in the federal system, and directors and shareholders should expect it to hold for ordinary contract debts, trade payables, and loans. The recurring exceptions are unpaid employee wages (federal and Ontario), unpaid vacation pay (Ontario specifically), unremitted source deductions (federal), and other statutory liabilities under tax, employment, and environmental law referenced in Ontario’s guidance. Alberta adds a structural option, the ULC, where the shield is removed entirely for shareholders by design, with liability that can outlast the corporation’s own existence by up to two years.

The sources reviewed for this article do not include the general Ontario or Alberta provisions that mirror CBCA s 45 (the basic “shareholders are not liable” rule) for ordinary, non-ULC corporations, nor the Income Tax Act and Excise Tax Act provisions on director liability for unremitted source deductions and GST/HST. Anyone assessing a specific liability question involving those provisions should confirm the current wording directly or with a lawyer, since this article covers only what is verified above.
