How to Register Incorporation in Ontario

What incorporation means in Ontario

Incorporation creates a separate legal body under Ontario law. That body can own property, sign contracts, and owe money.

The owners hold shares in the corporation. Their loss may stay limited to the money they invest.

That shield has limits. Directors may still owe taxes or face claims for harmful acts.

Registering a business name is not the same as incorporation. A business name links to a person or group.

A corporation starts as a new legal body after the filing gets approval. This guide explains how to register incorporation in Ontario.

• Sole proprietorship: One person owns and runs the business. The owner and business are the same legal person.
• General partnership: Two or more people run a business together. Each partner may share the firm's debts.
• Business corporation: One or more owners hold shares in a new legal body.

Choose a business structure that fits

A sole proprietor must be one person who runs a business for profit. The owner may register a business name if it differs from their own name.

The owner reports business income on a personal tax return. This structure has low setup costs, but it does not create a liability shield.

A general partnership needs at least two partners. The partners should set clear rules for profit, work, spending, and debts.

A written partnership deal can prevent many fights. It can set each partner's rights and duties.

A corporation needs at least one incorporator. An incorporator is the person or body that forms the corporation.

The corporation needs an Ontario office address. It also needs at least one director and at least one share owner.

Use this short test when choosing your structure:

• Choose a sole proprietorship for a simple, owner-run shop.
• Choose a partnership when two or more owners share the work.
• Choose a corporation when growth, shared ownership, or risk control matters most.

Eligibility rules before you file

Before registering a business in Ontario, gather the details for your chosen structure. The right details depend on the filing type.

A sole proprietor needs a business address and owner details. A partnership needs those details for each partner.

A corporation needs its office address, director details, share terms, and incorporator details. It must also state its main business activity.

Directors do not all need to live in Ontario. Still, the corporation must meet the filing rules that apply to Ontario companies.

Choose a name that does not mislead the public. Avoid a name that looks too close to another firm's name.

A numbered corporation may suit an owner who wants a quick filing. A named corporation needs a name search report.

Check the Ontario business name guide before you choose a name. It sets out key name rules and search details.

How to register incorporation through the Ontario Business Registry

The Ontario Business Registry lets you file and manage many Ontario firms online. You can also use an approved private filing firm.

These steps explain how to register incorporation through the online route. Check every entry before you send the filing.

1. Pick the structure. Choose a sole proprietorship, partnership, or corporation.
2. Choose a name. Pick a clear name that follows Ontario rules. A numbered corporation needs no business name choice.
3. Order a Nuans report. Get a report if you want a named corporation. The report compares your name with similar names.
4. Gather the details. Prepare the office address, owner details, director names, share data, and business activity.
5. Open the registry. Sign in to the Ontario Business Registry. You may also ask an approved filing firm to submit the form.
6. Complete the form. Enter the name, address, owners, directors, and business type.
7. Pay and file. Review each entry, pay the fee, and send the filing.
8. Save the records. Keep the receipt, filing number, certificate, and final papers.

Buy a Nuans report from an approved Nuans provider. A numbered corporation will often avoid that search cost.

The report can flag names that may cause a clash. It does not give you ownership of a brand or trade mark.

Order the report close to your filing date. It stays useful for a set time.

Ontario registration fees and payment choices

Your fee depends on the type of firm and the way you file. Private filing firms may add their own charge.

The table shows common online fees. Check the registry total before you pay.

Filing type	Common online fee	Other cost to plan for
Sole proprietorship	$60	Permits, licences, and name checks
General partnership	$60	Partnership deal and permits
Ontario corporation	$300	Nuans report for a named firm

A numbered corporation can skip the name report cost. It still pays the corporation filing fee.

Fees can change. Ask for the full price before hiring a private filing firm.

Use a payment method the registry accepts. Save the receipt with your firm records.

You may also need business permits and licences. The right permits depend on your town, industry, and work site.

What to do after incorporation

After filing, keep clear records for the corporation. Open a bank account in its name.

Use that account for firm costs and sales. Keep personal spending out of it.

The Ontario Business Identification Number, or BIN, is tied to your Ontario firm. Keep it with your certificate and other key papers.

You may need the BIN for later filings or registry updates. It helps identify the firm in Ontario records.

A BIN is not the same as a federal business number. The Canada Revenue Agency gives out the federal number.

You can learn about federal registration in the Canada Revenue Agency business number guide. Use that guide when you need tax accounts.

Keep the corporation's minute book up to date. Record share issues, director changes, and key decisions.

File required updates when details change. Report a new office address, director, or officer through the proper Ontario service.

• Open a bank account for the corporation.
• Store the certificate, receipt, BIN, and name report.
• Set up tax accounts when your work requires them.
• Check permits and licences for your location.
• Track annual filings and changes to firm details.

Resources for help with Ontario incorporation

The Ontario Business Registry is the main place for many online filings. Read the filing guidance before you start.

ServiceOntario can help with access and filing questions. It cannot choose your structure or give tailored legal advice.

An accountant can explain tax accounts and filing dates. A lawyer can review share terms, director duties, and owner agreements.

Use a private filing firm only when its role and price are clear. Ask what the fee covers before you give it your details.

For many small firms, the process is direct. The key is to choose the right structure and save each record.
