Corporation

A corporation is a distinct legal person created by statute. Once incorporated, it exists independently of its shareholders, directors, and officers. It can sue and be sued, own real property, enter into contracts, and carry on business — all in its own name.

This concept of separate legal personality was established in the landmark English case Salomon v Salomon & Co Ltd [1897] AC 22, and it remains the foundational principle of corporate law in Ontario today. The Ontario Business Corporations Act, RSO 1990, c B.16 (OBCA) and the Canada Business Corporations Act, RSC 1985, c C-44 (CBCA) both enshrine this principle.

The practical consequence is that a corporation's debts are its own. If an Ontario corporation cannot pay its creditors, those creditors generally cannot reach the personal assets of the shareholders — a doctrine known as the corporate veil.

To incorporate a provincial corporation in Ontario under the OBCA, the applicant must file Articles of Incorporation with the Ontario Ministry of Public and Business Service Delivery under Section 4 of the OBCA. The articles must include:

• The corporation's name (which must comply with naming rules under Section 10 of the OBCA and the Business Names Act)
• The municipality or geographic area in Ontario where the registered office will be located
• The classes and maximum number of shares the corporation is authorized to issue
• Restrictions on share transfers (if any)
• The number of directors (minimum and maximum)
• Any restrictions on business the corporation may carry on
• Any other provisions the incorporators wish to include

The government filing fee is $300 when filed online through Ontario Business Registry (OBR). After filing, the province issues a Certificate of Incorporation, and the corporation legally comes into existence on the date shown on that certificate (OBCA, s. 5).

In addition to Articles of Incorporation, a newly incorporated corporation should promptly adopt by-laws, hold an organizational meeting of directors, issue shares, and establish a minute book.

The separate legal personality of a corporation has several critical practical consequences in Ontario:

Perpetual existence: A corporation does not die when its shareholders or directors do. It continues until it is voluntarily dissolved or cancelled by the government for non-compliance.

Ownership of property: Real estate, intellectual property, equipment, and bank accounts are held in the corporation's name, not the shareholders' names. This simplifies transfers and estate planning.

Contractual capacity: The corporation, acting through its authorized officers and directors, can enter contracts that bind only itself — not the individual signatories personally (unless personal guarantees are given).

Litigation: The corporation sues and defends lawsuits in its own name. Shareholders are not parties to corporate litigation by virtue of their ownership alone.

Piercing the corporate veil: Ontario courts will disregard the separate personality of a corporation — "pierce the corporate veil" — in limited circumstances: fraud, using the corporation as a sham to evade legal obligations, or where a court finds the corporation is the alter ego of its controllers. This is an exceptional remedy and courts are reluctant to apply it.

Limited liability is the signature advantage of the corporate form. Under Section 92 of the OBCA, shareholders are not personally liable for the acts, defaults, or obligations of the corporation merely by reason of being shareholders. A shareholder's financial exposure is limited to the amount invested in shares.

In practice, however, this protection has exceptions that business owners should understand:

Personal guarantees: Lenders and landlords routinely require founders to personally guarantee corporate debts. When a guarantee is signed, the shareholder waives limited liability for that specific obligation.

Director liability: Directors (who may also be shareholders) face personal liability for unpaid wages and vacation pay under Section 131 of the OBCA, unremitted source deductions under the Income Tax Act, unremitted HST under the Excise Tax Act, and environmental damages. This is a critical distinction: shareholders are shielded, but directors are not for these statutory obligations.

Professional malpractice: Regulated professionals (lawyers, doctors, engineers) retain personal liability for their own negligence regardless of the corporate form.

One of the primary financial motivations for incorporation in Ontario is tax deferral. Corporate income is taxed at lower rates than personal income, allowing retained earnings to compound within the corporation before being distributed to shareholders.

Small Business Deduction (SBD): Canadian-controlled private corporations (CCPCs) are eligible for the Small Business Deduction under Section 125 of the Income Tax Act. The combined federal-Ontario rate on the first $500,000 of active business income is approximately 12.2% (9% federal + 3.2% Ontario provincial).

General corporate rate: Active business income above $500,000 is taxed at approximately 26.5% (15% federal + 11.5% Ontario).

Personal income tax comparison: Ontario's top marginal personal income tax rate is approximately 53.53% (federal + provincial combined). A business owner earning $300,000 through a corporation pays roughly 12.2% on that income inside the corporation, deferring the remaining tax until funds are paid out as salary or dividends.

Integration: Canadian tax policy uses the concept of integration — the total tax paid on income earned through a corporation (corporate tax plus personal tax on dividends) should approximate the total tax paid on the same income earned directly by an individual. Integration is imperfect, which is why tax planning with a qualified accountant is essential.

Capital gains: The lifetime capital gains exemption (LCGE) is available to shareholders of qualifying small business corporations (QSBCs) under Section 110.6 of the Income Tax Act. The 2024 LCGE is $1,016,602 (indexed annually), meaning a shareholder can potentially shelter over $1 million in capital gains on the sale of qualifying shares — a significant planning opportunity.

Advantages of incorporating in Ontario:

• Limited liability: Shareholders are not personally responsible for corporate debts (subject to exceptions noted above)
• Tax deferral: Active business income taxed at 12.2% (vs. 53.53% personal top rate), allowing capital to be retained and reinvested at a lower cost
• Capital gains exemption: LCGE on sale of qualifying shares
• Income splitting: Paying dividends to family members in lower tax brackets (subject to the Tax on Split Income / TOSI rules)
• Credibility: Many clients and lenders view corporations as more established and creditworthy than sole proprietors
• Perpetual succession: The business continues if an owner dies or departs
• Employee benefits: Corporations can offer tax-advantaged health and dental plans, group insurance, and retirement benefits

Disadvantages of incorporating:

• Cost and complexity: Initial incorporation costs $300-$1,500+ (government fees plus legal fees). Annual compliance obligations include corporate tax returns (T2), minute book maintenance, annual returns to Ontario, and potential audit exposure
• No flow-through of losses: Corporate losses cannot be applied against the shareholders' personal income (unlike a partnership or proprietorship)
• Trapped losses: If the corporation generates losses in early years, those losses cannot directly reduce the owners' personal tax
• Professional obligations: Directors have ongoing legal duties of care and loyalty under Sections 122-134 of the OBCA
• Salary/dividend extraction costs: Getting money out of the corporation requires paying salary (with payroll obligations) or dividends (no deduction for the corporation)

Ontario businesses can incorporate either provincially under the OBCA or federally under the CBCA. Key differences:

Name protection: CBCA corporations have name protection across Canada. OBCA corporations have name protection only in Ontario.

Registered office: CBCA corporations must maintain a registered office in Canada but can operate anywhere. OBCA corporations must maintain a registered office in Ontario.

Residency requirements: The CBCA requires that at least 25% of directors be Canadian residents (for boards with fewer than 4 directors, at least one must be a Canadian resident). The OBCA has no Canadian residency requirement for directors, making it more suitable for businesses with predominantly non-resident ownership.

Annual filings: CBCA corporations file an Annual Return with Corporations Canada. OBCA corporations file an Annual Return with the Ontario Ministry.

Operating in multiple provinces: A CBCA corporation can operate across Canada without registering as an extra-provincial corporation in each province (though some provinces require extra-provincial registration regardless). An OBCA corporation must register extra-provincially in each province where it carries on business.

Maria is a software consultant in Toronto earning $250,000 per year. Currently operating as a sole proprietor, she pays approximately $115,000 in combined federal and provincial personal income tax.

After incorporating Maria Tech Inc. under the OBCA:

• The corporation earns $250,000 in consulting fees
• Maria pays herself a salary of $80,000 (reasonable compensation)
• The remaining $170,000 stays in the corporation
• Corporate tax on $170,000 at 12.2% = approximately $20,740
• Maria pays personal tax on her $80,000 salary at a much lower effective rate

The $170,000 retained in the corporation is available for reinvestment into the business, invested in a corporate portfolio, or eventually distributed as dividends in a year when Maria is in a lower tax bracket. This tax deferral — keeping more money working in the business — is the primary financial driver of incorporation for small business owners.
