The Ontario Business Registry: What You Can Do Online

Running a business in Ontario means interacting with the provincial government for a range of filings — incorporation, business name registration, annual returns, and more. The Ontario Business Registry (OBR) is the province's online portal for those interactions, and it replaced a patchwork of older paper-based and in-person processes.

Understanding what the Ontario Business Registry is, what you can actually do through it, and what the "company key" concept means will save you time and frustration. This guide walks through the essentials.

What Is the Ontario Business Registry?

The Ontario Business Registry is an online platform operated by the Ontario government, accessible through the ServiceOntario website. It is the central registry for most Ontario business entities, including:

• Ontario corporations (incorporated under the Ontario Business Corporations Act, or OBCA)
• Not-for-profit corporations (under the Not-for-Profit Corporations Act, ONCA)
• Sole proprietorships and partnerships that have registered a business name
• Extra-provincial corporations (corporations incorporated outside Ontario that are doing business in Ontario and required to register here)
• Cooperatives and certain other entities

The registry is publicly searchable — anyone can look up a registered business name, find out whether a corporation is active, and get basic identifying information.

What You Can Do Through the OBR

1. Incorporate an Ontario Corporation

Ontario corporations are incorporated by filing Articles of Incorporation with the province. The OBR allows you to complete this filing online. When you incorporate through the OBR (or authorize a service provider to do so on your behalf), the province issues:

• A Certificate of Incorporation with a unique Ontario Business Identification Number (BIN)
• Articles of Incorporation reflecting the information submitted in the filing

What the Articles of Incorporation cover: the corporation's name, its authorized share structure, any restrictions on the business the corporation can carry on, and the number of directors.

Note that online incorporation through the OBR is a government filing process, not a full corporate setup. You still need organizational resolutions, share issuances, a minute book, bylaws, and (usually) a shareholders' agreement to be properly set up. The certificate is just the starting point.

2. File Articles of Amendment

If your corporation needs to change its name, alter its share structure, or amend other provisions of its articles, you file Articles of Amendment through the OBR. Unlike informal bylaw changes (which are internal), amendments to the articles require a formal government filing.

3. File an Annual Return

This is one of the most commonly missed obligations for Ontario corporations.

Ontario corporations incorporated under the OBCA are required to file an annual return each year. This is a filing with the Ontario government confirming the corporation's key information — its address, directors, and that it is still active. The annual return is due within 60 days of the corporation's anniversary of incorporation.

Important clarification: the Ontario annual return is a separate filing from:

• Your corporation's federal income tax return filed with the CRA
• Your T2 corporate tax return

Many business owners confuse these. Having your accountant file your tax returns does not satisfy the Ontario annual return obligation. Missing annual returns for several years can result in the corporation being dissolved by the province — which can come as an unpleasant surprise.

4. Register a Business Name (Sole Proprietorship or Partnership)

If you are operating a business under a name other than your own legal name — for example, "ABC Consulting" instead of "Jane Smith" — you are required to register that business name with the province. Business name registration is done through the OBR.

Registration is typically valid for five years and must be renewed. A registered business name is not the same as a trademark — registration protects your right to use the name in Ontario's registry and is required for opening business bank accounts, but it does not give you exclusive intellectual property rights to the name nationally.

5. Register an Extra-Provincial Corporation

If your corporation was incorporated in another province or territory (or federally under the CBCA) and it is carrying on business in Ontario, you may be required to register as an extra-provincial corporation in Ontario. This registration is done through the OBR.

"Carrying on business" in Ontario is not always straightforward to determine — it depends on the nature and regularity of your Ontario activities. If you are unsure whether registration is required, a lawyer can help you assess.

6. Dissolve a Corporation or Cancel a Business Name

If you are winding down your Ontario corporation, the formal step is filing Articles of Dissolution. If you are closing a registered business name, you can cancel that registration through the OBR. Dissolution requires the corporation to have no outstanding liabilities and, for tax purposes, requires coordination with your accountant.

7. File for Revival

A corporation that has been dissolved (by the province for failure to file annual returns, or voluntarily) can sometimes be revived — brought back to life — by filing articles of revival through the OBR. Revival has conditions and time limits, and is not always possible.

The Company Key: What It Is and Why It Matters

When Ontario launched the OBR, it introduced the concept of a company key — a code associated with each corporation in the registry. The company key acts as a password that gives the corporation's representatives authority to file documents and make changes on the OBR for that specific corporation.

If you incorporated before the OBR launched, your corporation was automatically added to the registry, but you were required to claim your company key to access the online filing functions. If your company key was never claimed, or was obtained by a former lawyer, accountant, or incorporator, you may not have access to your own corporation's OBR account.

This matters because:

• You cannot file an annual return or make changes to the OBR without the company key
• If no one can locate the company key, it may need to be reset through ServiceOntario
• Corporations whose annual returns fall behind because of company key confusion face dissolution risk

Make sure you know where your company key is and that it is under the control of the right person — typically the president, sole director, or authorized representative of the corporation.

What the OBR Does Not Do

The OBR is a government registry for administrative filings. It does not:

• Provide legal advice
• Confirm whether your corporate structure is set up correctly
• Draft shareholder agreements, bylaws, or other internal governance documents
• Reserve or protect your business name as a trademark
• Ensure your corporation is compliant with the OBCA or other applicable laws

Filing through the OBR is a transaction with the government. The legal strategy behind that transaction — which share classes to create, whether to incorporate provincially or federally, how to structure ownership — is separate work.
