How to Incorporate a Business in Ontario: A Step-by-Step Guide & Checklist
Thinking about incorporating your business? Knowing how to incorporate a business in Ontario can help you choose the right structure, prepare the correct documents and avoid costly mistakes before you start operating.
Incorporation creates a separate legal entity for your business. It can help establish clearer ownership, support long-term growth and provide limited liability in many circumstances. However, it also comes with additional paperwork, tax filings and ongoing responsibilities.
The good news is that you can incorporate an Ontario business online without necessarily hiring a lawyer. The key is understanding what decisions you need to make before submitting your application.
This guide explains how to incorporate in Ontario, how much it costs, what information you need, how to file online and what to do once your corporation is approved.
What Does It Mean to Incorporate a Business in Ontario?
Incorporating a business means creating a corporation that exists as a legal entity separate from its shareholders.
Unlike a sole proprietorship, where the owner and business are generally treated as the same legal person, an incorporated business can own assets, enter contracts, incur debts and carry on business in its own name.
An Ontario business corporation is generally governed by the Ontario Business Corporations Act (OBCA).
What changes when you incorporate?
When you incorporate, you establish a formal corporate structure with responsibilities that may include:
Appointing directors to oversee the corporation.
Issuing shares to establish ownership.
Maintaining corporate records.
Filing required corporate and tax returns.
Keeping business finances and personal finances separate.
Important: Incorporation does not automatically transfer an existing business into the corporation. Assets, contracts, licences, employees and tax registrations may need to be transferred or updated separately.
How to Incorporate a Business in Ontario: Quick Answer
To incorporate a business in Ontario, choose your corporate name, prepare your incorporation details, establish your share structure and directors, and submit your Articles of Incorporation through the Ontario Business Registry. Pay the applicable filing fee and retain your approved incorporation documents. After incorporation, establish corporate records, address tax registrations and maintain ongoing filing obligations.
Step-by-Step: How to Incorporate a Company in Ontario
Follow these steps before and during your incorporation.
Step 1: Decide Whether Incorporation Is Right for Your Business
Before filing, consider why you want a corporation and whether the added administration makes sense for your situation.
Incorporation may be worth considering if you:
Want to separate your business activities from your personal affairs.
Plan to bring in co-founders or shareholders.
Expect to retain profits in the business for future growth.
Need a corporate structure for certain contracts or financing opportunities.
Want to build a business that may eventually be sold or transferred.
A sole proprietorship may be simpler when you are testing an idea, working on a small scale or operating a business with limited administrative needs.
Consideration | ||
Legal identity | Generally the owner and business are the same legal person | Separate legal entity |
Liability | Owner generally bears business liabilities personally | Shareholder liability is generally limited, subject to exceptions |
Income tax | Business income reported on the owner's personal return | Corporation files its own corporate tax return |
Administration | Usually simpler | More records, filings and compliance |
Ownership | Owned by an individual | Ownership represented by shares |
Ongoing costs | Generally lower | Usually higher due to accounting and corporate requirements |
Practical tip: Do not incorporate solely because you have heard corporations always pay less tax. The tax outcome depends on income, expenses, how money is withdrawn, eligibility for deductions and your circumstances. Discuss the numbers with an accountant.
One of your first decisions is where to incorporate.
An Ontario corporation is incorporated under Ontario legislation. A federal corporation is incorporated under the Canada Business Corporations Act.
Feature | ||
Governing legislation | ||
Initial filing | ||
Name considerations | Ontario corporate name requirements and search | Federal name rules and name review |
Operating in other provinces | May require additional-provincial registration where applicable | May also require registration in provinces where it carries on business |
Ongoing compliance | Ontario corporate filings and applicable tax obligations | Federal annual return and applicable provincial registrations and filings |
Federal incorporation does not automatically eliminate provincial registration requirements. Similarly, an Ontario corporation can serve customers outside Ontario, although the nature of its activities may trigger requirements in other jurisdictions.
Which should you choose?
Consider Ontario incorporation if your head office and main operations are in Ontario and a provincial corporation meets your needs. Consider federal incorporation if nationwide name considerations or other federal corporate requirements are important to your plans. Compare the actual filing requirements and ongoing obligations before deciding.
Step 3: Choose a Corporate Name
Your corporation can generally have either a named corporation or a numbered corporation.
A named corporation uses a name you select, subject to applicable naming requirements and approval. For example, a hypothetical business might be called Maple Ridge Creative Inc.
A numbered corporation uses a government-assigned number followed by a legal element, such as 12345678 Ontario Inc.
A numbered corporation can still operate under a separate business or trade name when the appropriate registration requirements are met.
How do you check whether an Ontario corporate name is available?
If you want a named Ontario corporation, obtain the required Ontario-biased or weighted NUANS name search report through an authorized provider. A federal-biased NUANS report is not a substitute for the Ontario report required for an Ontario named incorporation.
A search is an important screening step, but it does not guarantee that your name will be accepted or that it will not infringe someone else's rights.
Before deciding on a name:
Search the Ontario Business Registry for existing businesses and corporations.
Arrange the appropriate NUANS report if required.
Check for similar names and relevant trademarks.
Confirm that the name meets corporate naming requirements.
Consider whether the corresponding website domain and social media handles are available.
You may want to use a different public-facing brand name from your corporation's legal name. Make sure you understand the applicable business name registration requirements before using it.
Common mistake: Assuming that an available business name is automatically protected as a trademark. Corporate name approval and trademark protection are different matters.
Step 4: Prepare Your Articles of Incorporation
The Articles of Incorporation are the foundational documents that establish your corporation.
You will need to make several decisions before completing the application.
Choose your registered office address
Your registered office is the corporation's official address for required corporate records and formal documents. Use an address that meets applicable requirements and where important correspondence can be received reliably.
Understand whether the address you use may appear on public records before submitting your application.
Directors oversee the corporation and have legal duties associated with their role.
Confirm the eligibility requirements for each proposed director. Ontario corporations do not have the same Canadian-resident director requirement that applies to certain federal corporations under the federal regime.
Collect the information requested by the filing system and ensure all details are accurate.
Decide on your share structure
Shares represent ownership in a corporation. Your Articles of Incorporation must specify a share structure that meets your business's needs and Ontario's requirements.
Consider:
Whether there will be one shareholder or several.
Whether one class of shares is sufficient.
Whether different share classes or rights may be needed.
Whether the corporation may bring in investors or transfer ownership in the future.
For example, a sole owner may need a straightforward structure. Two co-founders may need to consider how ownership, voting rights and future decisions will be handled.
Do not divide shares casually simply because two founders are starting the business together. The percentage of ownership can affect control, distributions and future transactions.
If the corporation will have multiple shareholders, investors, complex share rights or a planned sale, obtain legal and tax advice before filing. Changing the share structure later may require formal corporate approvals and an Articles of Amendment filing.
Include any other required provisions
Your articles may need to address the number of directors, restrictions on business activities, restrictions on share transfers or other provisions, depending on your intended structure.
Review the complete proposed articles before submitting them.
Step 5: Incorporate Your Business Online
Before you begin, gather:
Your proposed corporate name or decision to use a numbered corporation.
Your applicable NUANS report if incorporating under a name.
The registered office address.
Director details.
Your intended share structure.
Any additional provisions required for your corporation.
A valid payment method.
Then:
Access the appropriate incorporation service.
Enter the requested corporate information.
Review the name, director information, address and share structure.
Confirm that your proposed articles accurately reflect your decisions.
Submit the filing and pay the applicable fee.
Save the confirmation and approved incorporation documents.
Follow the current instructions shown in the registry. The exact screens and information requested may change.
Can you incorporate a business in Ontario online?
Yes. Ontario business corporations can be incorporated online through the Ontario Business Registry. You do not necessarily need to visit a government office or hire a lawyer, although professional assistance can be useful if your structure is complex or you are unsure how to prepare your articles.
You can also use a business incorporation service to help prepare and submit the filing.
Step 6: Receive and Review Your Incorporation Documents
Once your application has been accepted, retain the official incorporation documents in a secure location.
Review the documents to confirm that the corporation's name, registered office, directors and articles match the intended filing.
Keep copies of the Articles of Incorporation, filing confirmation and other records supplied with the completed application.
If you identify an error, determine the correct process for addressing it. Do not assume every mistake can be corrected simply by editing an online profile.
Step 7: Set Up Your Corporate Records and Ownership
Incorporation is not complete from an operational perspective just because your articles have been approved.
Your corporation needs appropriate records of its organization and ownership.
Depending on the circumstances, these may include:
Initial director and shareholder resolutions.
Corporate bylaws.
Director consents.
Share subscriptions and share issuance records.
A securities register and shareholder records.
Records of significant decisions and transactions.
Information about individuals with significant control, where required.
The exact requirements depend on the corporation and applicable law.
A minute book is the organized collection of important corporate records. It may be maintained electronically or in another suitable format, provided the records meet applicable requirements.
Practical tip: Establish your records when the corporation is formed rather than waiting until a bank, accountant, investor or buyer asks for them.
Step 8: Set Up Your CRA Business Accounts
An Ontario corporation's provincial incorporation and its federal tax accounts are different things.
The corporation may need a Canada Revenue Agency Business Number (BN) and one or more program accounts, depending on its activities.
Review the CRA's Business Number and program account guidance to determine what is required.
Common accounts include:
Corporate income tax: A corporation generally has a corporate income tax filing obligation, even if it has little or no activity. Confirm the filing requirements for your circumstances.
GST/HST: Registration is generally required when the business exceeds the applicable small-supplier threshold, subject to the rules and exceptions. Voluntary registration may be possible in some circumstances.
Payroll: A payroll program account is needed when applicable payroll obligations arise.
Import/export: An appropriate account may be required if the corporation engages in relevant activities.
Do not assume that the Ontario Business Identification Number (BIN), a CRA Business Number and a corporate number are interchangeable. They serve different purposes.
If you need help with CRA HST or payroll registration, consider using an appropriate service provider or accountant.
Step 9: Open a Corporate Bank Account and Organize Your Finances
A separate corporate bank account helps distinguish company money from personal funds and supports accurate bookkeeping.
A financial institution may request your Articles of Incorporation, corporate number, director and ownership information, identification and other supporting documents.
You should also:
Set up bookkeeping software or another reliable accounting system.
Track income, expenses and receipts.
Establish a process for reimbursing business expenses.
Decide how salary, dividends or other payments will be handled with professional guidance.
Keep sufficient funds available for tax obligations and operating costs.
A corporation is a separate legal entity. Mixing personal and corporate finances can create accounting, tax and governance problems.
Step 10: Check Licences, Permits and Insurance
Incorporation does not automatically authorize you to carry on every type of business.
Depending on your industry, location and activities, you may need municipal licences, provincial permits, professional authorizations or other approvals.
Check the Government of Canada's BizPaL permit and licence service and the relevant provincial or municipal authority.
You should also review your insurance needs. Commercial general liability, professional liability, property, cyber or other coverage may be appropriate depending on your business.
Limited liability is not a substitute for suitable insurance.
How Much Does It Cost to Incorporate in Ontario?
The Ontario government fee for incorporating a business corporation is $300. A named corporation may also require a paid NUANS report, and professional assistance or other services can add to the total cost.
Cost item | What to expect |
Ontario incorporation fee | $300 government fee |
NUANS report | Required for a named corporation |
Incorporation assistance | Varies by service provider and options |
Accounting and taxes | Depends on transaction volume and complexity |
Legal advice | Varies by provider |
Ongoing maintenance | Includes annual filings, bookkeeping, tax returns & updates |
The total cost depends on whether you choose a numbered or named corporation, how much assistance you need and the complexity of your structure.
When comparing incorporation services, check what is actually included. A low advertised price may not include a name search, organizational records, share issuance documentation or support after filing.
How Long Does It Take to Incorporate a Business in Ontario?
Online incorporation can be processed quickly when the application is complete and accepted. However, timing depends on the filing method, the quality of the information supplied, name review requirements and any issues raised during the process.
Do not assume that every named incorporation will be completed in the same amount of time.
If you have a contract deadline, financing condition or other time-sensitive commitment, allow room for delays and confirm the current processing information before making promises to others.
What Are the Ongoing Requirements After Incorporation?
Your corporation continues to have responsibilities after the initial filing.
File the required annual return
Ontario corporations generally must file an annual return through the Ontario Business Registry within six months after the end of their fiscal year. The annual return is a corporate information filing and is separate from the corporation's income tax return.
Keep corporate information current
Report changes to corporate information when required. Changes may include directors, registered office details, officers or other information, depending on the type of change and applicable filing rules.
Use the correct filing for the change. For example, certain changes to articles, such as the corporation's name or share structure, may require Articles of Amendment rather than a routine information update.
File corporate income tax returns
A corporation generally files a T2 Corporation Income Tax Return for each tax year, even if it has no tax payable, subject to the applicable rules.
Confirm filing deadlines and any exceptions with the CRA or a qualified tax professional.
Maintain your records
Keep corporate records, ownership information, resolutions, financial records and other required documents organized and up to date.
Your corporation may also need to maintain information about individuals with significant control and comply with applicable disclosure requirements.
Meet other business obligations
Depending on your activities, you may need to maintain HST registration, payroll accounts, permits, insurance and other registrations.
Create a compliance calendar so you know what is due and when.
Common Mistakes to Avoid When Incorporating in Ontario
1. Choosing a name without checking it properly. A registry search alone does not guarantee approval or trademark protection.
2. Using a share structure without considering future plans. Ownership and share rights should reflect the needs of the founders and the corporation.
3. Assuming incorporation protects you from every liability. Personal guarantees, personal wrongdoing and certain legal obligations can still expose an individual to liability.
4. Mixing personal and corporate finances. Keep clear records and use appropriate accounts.
5. Forgetting post-incorporation filings. Annual returns, tax returns and required corporate updates are separate responsibilities.
6. Assuming the old business automatically transfers. Existing contracts, assets, permits, registrations and tax accounts may require separate steps.
7. Treating incorporation as tax advice. The right way to pay yourself and structure ownership depends on your specific circumstances.
8. Ignoring public disclosure. Certain corporate information may be available through public records. Understand the applicable disclosure rules before submitting personal or business information.
