You’ve got a brilliant idea, a killer work ethic, and a dream of being your own boss. But before you start printing business cards or launching your website, there is one crucial hurdle: making it official.
If you’re planning to fly solo, Ontario sole proprietorship registration is your ticket to the game. It’s the quickest, most affordable way to get your business off the ground. Whether you’re a freelance graphic designer in Toronto or a mobile pet groomer in Ottawa, getting your paperwork right from day one is essential.
In this guide, we’ll walk you through how to register a Sole Proprietorship in Ontario using the streamlined power of Biz Ontario. No legal headaches, no confusing government portals—just a clear path to your first sale.
What Exactly is a Sole Proprietorship?
A sole proprietorship is the simplest business structure in Canada. Legally speaking, you and the business are one and the same. This means:
- Total Control: You make 100% of the decisions.
- Simple Taxes: You report your business income on your personal T1 tax return.
- Personal Liability: Since you and the business are the same entity, you are personally responsible for any business debts or legal issues.
For many, this is the perfect starting point before transitioning to an Ontario corporation later on.
When Do You Need Ontario Name Registration?
One of the biggest questions new entrepreneurs ask is: “Do I even need to register?”
In Ontario, you are not required to register if you are doing business under your own legal name (e.g., “Jane Doe”). However, if you add even one word to that name—like “Jane Doe Consulting”—it becomes a “trade name,” and Ontario name registration becomes mandatory under the Business Names Act.
Why register even if you don’t “have” to?
- Professionalism: Clients feel more secure paying “North Star Marketing” than an individual.
- Banking: You cannot open a business bank account without a valid Master Business Licence (now called a Business Name Registration).
- Legal Compliance: It ensures you aren’t accidentally infringing on another local business’s identity.
How to Register a Sole Proprietorship in Ontario: A Step-by-Step Guide
The process for small business registration Ontario has moved entirely online, making it faster than ever. Here is how to navigate it through Biz Ontario.
Step 1: Choose Your Business Name
Your name is your brand. It needs to be catchy, but it also needs to follow the rules. In Ontario, your name cannot be “deceptive” (suggesting you’re a government agency) or “prohibited” (obscene language).
Expert Tip: Before you file, do a quick search on the Ontario Business Registry to see if someone else is already using your dream name. While a sole proprietorship doesn’t offer the same “name protection” as a corporation, you want to avoid confusion—and potential lawsuits—from the start.
Step 2: Gather Your Information
To complete your Ontario sole proprietorship registration, you’ll need the following ready:
- NAICS Code: This is a 2-to-6-digit code that describes your industry (e.g., “541430” for Graphic Design).
- Business Address: A physical address in Ontario (your home office is fine!).
- Your Personal Info: Legal name, email, and address.
Step 3: File Through Biz Ontario
Instead of wrestling with the Ministry’s manual forms, Biz Ontario provides a user-friendly interface that guides you through the application.
- Enter your business details.
- Pay the provincial registration fee (currently $60).
- Receive your documents instantly.
Understanding Your Registration Documents
1. The Business Name Registration (formerly Master Business Licence)
This is your official proof of registration. It contains your Business Identification Number (BIN). You will need this document to open bank accounts and sign contracts.
2. The Company Key
This is a unique code provided by the government. Keep it safe! You’ll need this key to make any changes to your business (like changing your address) or to renew your registration in the future.
Beyond the Registration
Registering your name is the first step, but small business registration Ontario involves a few “Phase 2” tasks to ensure you stay on the right side of the law.
CRA Business Number & HST
Your provincial registration is for Ontario. You also need to deal with the federal government (CRA).
- If you earn over $30,000/year: You must register for an HST account and collect tax on your sales.
- CRA Business Number (BN): This 9-digit federal number is used for taxes, payroll, and importing/exporting.
Municipal Permits
While Biz Ontario handles your provincial standing, some cities require a local permit. For example, if you are running a daycare, a food truck, or a home-based hair salon, check with your local City Hall to see if you need a specific municipal license.
Renewal
Unlike a corporation, which lasts forever, an Ontario sole proprietorship registration expires every five years. Mark your calendar! If you forget to renew, your BIN will be cancelled, and you’ll have to start the process over.

Frequently Asked Questions: Ontario Sole Proprietorship Registration
Starting a business is a big step, and it’s normal to have questions about the logistics. Here are the most common things entrepreneurs ask about small business registration in Ontario.
1. How much does it cost to register a sole proprietorship?
The Ontario government fee for Ontario name registration is currently $60. This registration is valid for five years. Keep in mind that using a service like Biz Ontario will involve a small service fee to ensure your application is handled correctly and filed instantly, saving you time and potential errors.
2. Can I use my own name as my business name?
Yes! If you are operating under your exact legal name (e.g., “Sam Smith”), you are not legally required to register. However, if you add any descriptive words (e.g., “Sam Smith Photography” or “Smith & Co.”), you must complete your Ontario sole proprietorship registration.
3. Does a sole proprietorship protect my personal assets?
No. Unlike an Ontario corporation, a sole proprietorship does not create a separate legal entity. You are personally liable for all business debts and legal obligations. If liability is a major concern for your industry, you might want to consider business incorporation in Ontario instead.
4. How long does it take to get my Master Business Licence?
When you register through the Biz Ontario platform, the process is digital and extremely fast. In most cases, you will receive your Business Name Registration (formerly called a Master Business License) via email within the same business day.
5. Do I need a separate bank account for a sole proprietorship?
While not legally required for tax purposes (since you and the business are one), it is highly recommended. Most Canadian banks will require a Business Name Registration document to open a business account. Keeping your personal and business finances separate makes accounting and tax season much easier.
6. What is a BIN, and where do I find it?
A BIN is your Business Identification Number. It is a 9-digit number issued by the Province of Ontario when you register. You can find it on the top right corner of your registration documents. Note that this is different from the 9-digit federal Business Number (BN) issued by the CRA.
7. How do I renew my registration?
Your Ontario name registration expires every five years. The government does not always send reminders, so it is your responsibility to renew it. You can easily renew your registration through Biz Ontario using your Company Key.
