Corporations in Canada

A common question that Canadian financial and tax advisors are asked by their clients is whether they should set up a corporation. It is often mistakenly assumed that it is always better to operate a business or own investments through a private corporation. The purpose of this article is to provide more information about the benefits that a corporation can provide, as well as identify some potential traps that individuals should be aware of before setting up a private corporation in Canada.

What Is a Corporation?

In Canada, a corporation is a legal entity that exists independently of its owners. A corporation can enter into contracts and own property. The owners of a corporation are called shareholders, and an individual can become a shareholder by purchasing shares directly from the corporation or from another shareholder.

The process of creating a corporation is called incorporation and involves a legal professional drafting a document called Articles of Incorporation and submitting the articles to the appropriate federal, provincial, or territorial government for approval.

Benefits of a Corporation

One of the primary benefits of operating a business through a corporation is that a corporation provides legal protection to its shareholders. Since a corporation is a separate legal entity, shareholders are generally not personally responsible for the debts and liabilities of the corporation. In contrast, with a sole proprietorship, the owner of the business has unlimited liability, meaning that if the business incurs debts, the proprietor may be personally liable if the business cannot repay them.

A second benefit of a corporation is access to the small business deduction, which significantly reduces the corporate tax rate for a Canadian-controlled private corporation (CCPC) on the first $500,000 of active business income. The combined federal and Ontario corporate tax rate for a qualifying small business corporation is currently 12.2% (dropping to 11.2% on July 1, 2026) on the first $500,000 of active business income. By comparison, the highest personal marginal tax rate in Ontario is 53.53%. As a result, a Canadian business owner may be able to defer a significant amount of personal tax by earning active business income through a corporation.

Small business corporate tax rates vary by province, generally ranging from approximately 9% to 12.2%, and are significantly lower than the highest personal marginal tax rates.

Another potential benefit of a corporation is the opportunity for income splitting. When an individual earns income personally, that individual must report all of the income on his or her personal income tax return. When income is earned through a corporation, however, the corporation may subsequently pay dividends to shareholders. This flexibility in how corporate earnings are distributed can create opportunities for couples and families to shift income into the hands of individuals in lower marginal tax brackets.

Income splitting is a complex topic, and there are many anti-avoidance rules—such as the Tax on Split Income (TOSI) rules—designed to limit inappropriate income splitting through corporations. Individuals should consult a qualified tax advisor before implementing any income-splitting strategies.

When Is It Worthwhile to Set Up a Corporation?

In Canada, there is no requirement to operate a business through a corporation. For very small or newly established businesses, operating as an unincorporated sole proprietorship may offer certain advantages over incorporating.

Setting up and maintaining a corporation can be expensive due to professional fees, including legal fees to prepare Articles of Incorporation and annual corporate resolutions, as well as accounting fees to prepare annual financial statements and corporate tax returns.

Another advantage of a sole proprietorship is that if the business generates losses, those losses can generally be deducted against the proprietor’s other sources of income for tax purposes. If a corporation incurs losses, however, those losses remain within the corporation and generally cannot be used personally by the shareholder to offset taxes on other income.

Generally, it makes sense for an individual to operate a business through a corporation once the business becomes consistently profitable and the tax and legal benefits of incorporation outweigh the additional costs of establishing and maintaining the corporation.
