How to Incorporate a Business in Ontario: A Step-by-Step Guide

If you're starting a business in Ontario, you've probably heard you should incorporate — but the actual process of incorporating a business in Ontario can feel opaque. What forms do you file? In what order? What decisions do you have to make upfront? This guide walks you through every major step, from the name search to your first directors' meeting.

Incorporating creates a separate legal entity. That means your personal assets are generally shielded from business debts, you can split income with a corporation, and you have a professional structure investors and clients recognize. The tradeoffs — cost, paperwork, annual filings — are real but manageable.

Step 1: Choose Federal or Provincial Incorporation

The first fork in the road is whether to incorporate under the Ontario Business Corporations Act (OBCA) or the Canada Business Corporations Act (CBCA).

• Provincial (OBCA): Cheaper and simpler if you operate mainly in Ontario. As of writing, OBCA has no director residency requirement — that requirement was removed in 2021, meaning all your directors can be non-residents of Canada.
• Federal (CBCA): Required if you need to operate under the same name across all provinces or want the flexibility of a nationally registered entity. The CBCA still requires 25% of directors to be Canadian residents as of writing — verify the current rule, as federal legislation can change.

For most Ontario-based founders, an Ontario corporation is the right default.

Step 2: Run a NUANS Name Search (Named Companies Only)

If you want a named company (e.g., "Maple Ridge Consulting Inc."), you must conduct a NUANS search — Newly Upgraded Automated Name Search — to confirm no existing business already holds a confusingly similar name.

What NUANS checks

• Corporate names registered federally and provincially
• Trademarks on the Canadian Trade-marks Register
• Business names registered in Ontario

A NUANS report is valid for 90 days (verify the current period with ServiceOntario). You submit the report as part of your articles of incorporation. If your proposed name is too similar to an existing one, the government will reject your filing.

Tip: A numbered company (e.g., 1234567 Ontario Inc.) skips the name search entirely. Ontario assigns the number automatically. Numbered companies are common for holding companies and professional services providers who brand under a trade name anyway.

Step 3: Prepare and File Articles of Incorporation

The Articles of Incorporation (Form 1 under the OBCA) are the constitutional document of your corporation. Key choices you make here:

Share structure

You must define at least one class of shares. Most incorporators authorize an unlimited number of common shares. If you plan to issue different classes (e.g., preferred shares, multiple voting classes), you describe each class's rights and restrictions here.

Restrictions on share transfer

Private corporations in Ontario typically include a restriction that shares can't be transferred without board or shareholder approval. This keeps your company "private."

Number of directors

You declare a minimum and maximum number of directors (e.g., "minimum 1, maximum 10"). You can also fix an exact number.

Restrictions on business activity

Most incorporations leave this blank, allowing any lawful business. Regulated professions (law, medicine, accounting) have special rules.

You file through the Ontario Business Registry (OBR) online or through a lawyer. There is a filing fee as of writing — verify the current amount with ServiceOntario.

Step 4: Organize the Corporation — First Directors' Resolutions

Filing articles creates the legal shell. You then "organize" the corporation with a written resolution of the first directors, which covers:

• Appointing officers (President, Secretary, etc.)
• Adopting by-laws governing how the company operates (meetings, quorum, signing authority)
• Issuing shares to founders
• Opening a bank account and designating signing officers
• Appointing an accountant if desired

This resolution, along with the by-laws, goes into the minute book (see Step 6).

Step 5: Issue Shares to Founders

The corporation issues shares under a share subscription. Each founder agrees to pay a price per share and receives a share certificate. The amount paid becomes the corporation's stated capital.

For a two-founder startup paying a nominal amount each, this is straightforward. If you have co-founders with different roles or different capital contributions, you may want to design voting and economic rights carefully before issuing shares — after issuance, restructuring is more complicated and may trigger tax consequences.

Step 6: Set Up Your Minute Book

Every Ontario corporation is legally required to maintain certain corporate records. These are kept in the minute book, which includes:

• Articles of Incorporation and any amendments
• By-laws and any amendments
• Resolutions of shareholders and directors
• Register of shareholders (who owns what shares and for how much)
• Register of directors
• Register of officers

The minute book doesn't have to be a physical binder — a digital record kept by your lawyer or a cloud-based corporate records service works. The critical thing is keeping it current: every share transfer, director change, or major resolution needs to be documented.

Step 7: Register the Business Name (If Using a Trade Name)

If your corporation carries on business under a name other than its corporate name (e.g., your numbered company operates as "Sunrise Digital"), you must register that business name under the Ontario Business Names Act. This is separate from incorporation.

After Incorporation: Ongoing Obligations

• Annual return: File a corporate annual return through the OBR — as of writing, Ontario requires this annually for active corporations. Verify timing and fees.
• HST registration: If your annual revenue will exceed the GST/HST threshold (verify with CRA), register for an HST account.
• Corporate tax returns: Your corporation must file a T2 return with CRA each year, even if it had no income.
