How to Start a Business in Ontario: The 12-Step Checklist

Starting a business is equal parts momentum and reality. You’re building something of your own, but you’re also signing up for long hours, real competition, and financial responsibilities that stretch well beyond your initial startup costs. It’s a lot to take on, but with the right roadmap and support, it’s absolutely manageable.

Ontario has specific legal requirements every business owner must meet before opening their doors. From choosing a structure to the moment an entrepreneur registers their business with the Ontario government, there are important steps you can’t afford to skip. 

This 12-step checklist walks you through everything: from your first idea to launch day, including how to create a comprehensive business plan and stay compliant along the way. And when you’re ready to register, Ownr is here to make it simple.

Key Takeaways

• Starting a business in Ontario means meeting specific legal requirements (structure, registration, licences, and tax obligations) before you open your doors.
• A strong business needs more than a good idea; market research, a business plan, and secured funding are all part of the process.
• Ownr offers a faster, more affordable alternative to navigating the Ontario Business Registry on your own.

Legal Requirements for Starting a Business in Ontario

To start your business off right, there are a few legal requirements you’ll need to consider. 

Registering your business

Starting a business in Ontario means getting the legal foundation right from day one. Before you launch, you’ll need to determine your business’s legal structure (sole proprietorship, partnership, or corporation), as this affects your taxes, liability, and reporting obligations.

Once a business owner determines the appropriate legal structure, registration requirements follow. Sole proprietors operating under their own legal name aren’t required to register. But any other name, partnership, or corporation must register with the province. 

When you file Articles of Incorporation, your business name gains legal protection in every jurisdiction you incorporate. Incorporating federally extends that protection nationwide. Ownr can help you incorporate quickly, at a fraction of the cost of a lawyer.

Applying for a GST/HST number

If your business earns more than $30,000 in revenue over 12 months, you’re required to register for HST collection with the CRA. Even if you’re below the threshold, registering early has its advantages. You can claim input tax credits on business expenses before you even hit the limit. 

To do this, you’ll first need to obtain a federal Business Number, which acts as your business ID for tax purposes. How much you remit depends on your reporting method (quick method vs. long method), so it’s worth discussing with an accountant to find the most cost-effective approach for your business.

Obtaining licenses or permits

You may need specific licences or permits to operate your business. You can quickly and easily get a detailed list of all the licences and permits you may need for your type of business with BizPal, an online tool jointly managed by all levels of government.

Now that we’ve covered the basic legal requirements of starting a small business in Ontario, let’s dive into our 12-step checklist for getting your business off the ground.

12 Steps to Starting a Business in Ontario

Now that you’ve covered the legal basics, it’s time to get into the actual building blocks of your business. Here’s a step-by-step breakdown of everything you need to do to go from idea to fully operational in Ontario.

1. Come up with a business idea

Every business starts with a clear idea, but the strongest ones solve a real problem for a specific audience. At this stage, focus on what you’re offering, who it’s for, and why it matters. Look at your skills, experience, and the market gaps you can realistically fill.

Consider how and where you want to work, too. If you’re not a people person, an e-commerce store makes more sense than a brick-and-mortar shop. If your idea requires significant resources, you’ll need to think early about how to secure startup capital. 

Not every business needs a big budget to launch. But every business needs a clear, compelling idea to build on.

2. Research the market

Market research helps you validate your idea before you invest serious time or money. Conduct an Ontario market analysis to understand local demand, competitors, and pricing expectations.

Your research should answer the key questions: 

• Who is your target customer? 
• Is there enough demand? 
• What are competitors doing and where are they falling short? 
• How much will people pay?

Tap into resources like Statistics Canada, the Canadian Industry Statistics database, and your local Small Business Enterprise Centre. Online tools like Google Forms or SurveyMonkey make it easy to poll potential customers directly.

3. Choose a business name

Your business name is often the first impression you make. So choose something unique, memorable, and (legally) available. Start by Googling potential names and checking domain availability. Ideally, your domain and social media handles match your business name.

From there, every entrepreneur who incorporates must complete a NUANS name search to ensure the name isn’t already taken or trademarked. You can search the NUANS database and the Canadian trademark database before committing.

With Ownr, you can pre-search up to 30 names, saving on search fees. Incorporating also protects your business name in Ontario. No other business can legally use it within your jurisdiction.

Important: All incorporated businesses must include a legal element at the end of their name: Limited, Incorporated, or Corporation (Ltd., Inc., or Corp.).

4. Choose a business structure and register or incorporate

Once your name is set, you’ll need to formalize how your business operates in Ontario. Your business structure affects everything. Your taxes, liabilities, and how you raise funding. Here’s a quick breakdown:

• Sole proprietorship: Simple to set up, but you’re personally liable for all debts and taxed at personal income rates.
• Partnership: Shared ownership and responsibilities, but personal liability still applies to all partners.
• Corporation: A separate legal entity that protects your personal assets and opens doors to better funding options and tax advantages.

Every incorporated business must establish a registered office in Ontario and meet provincial requirements for ongoing compliance and reporting. It’s more paperwork upfront, but Ownr simplifies the entire process so nothing falls through the cracks.

5. Write a business plan

Think of your business plan as your blueprint. It maps out where you’re going and how you’ll get there. It’s also your most powerful tool for securing funding from banks or investors, since most will want to see one before committing.

Writing it forces you to prepare operational infrastructure early, from staffing and tools to day-to-day workflows. A solid business plan should cover your target market, competitive landscape, revenue model, financial projections, and operational approach.

Not sure where to start? Ownr offers a free business plan generator to help guide you through the process.

6. Purchase a domain name and set up social media accounts

Once your business name is locked in, secure your digital real estate before someone else does. Purchase your domain name, ideally a .ca or .com that matches your business name exactly. 

Then, claim your handles across all major social media platforms: Instagram, Facebook, LinkedIn, TikTok, YouTube, and Pinterest. Even if you don’t plan to use every platform right away, securing them protects your brand identity.

This step supports early visibility but also helps you protect your business name in Ontario by reducing the risk of others using it online. As you set things up, make sure your contact details and branding are consistent so your business appears credible and easy to find.

7. Open a business bank account

Every business owner should open a business banking account early, and for corporations, it’s a legal requirement. Without one, neither vendors nor customers can make payments to the corporation. 

Even for sole proprietors and partnerships, keeping your personal and business finances separate is one of the simplest ways to stay organized from the start. Setting this up early makes bookkeeping cleaner, tax season less stressful, and any potential audits far more manageable. Account fees are also tax-deductible, so it’s a practical win on multiple fronts.

Opening an RBC business account is quick. Apply online in under 15 minutes and receive your account number right away. Ownr clients get money back when they open an RBC business account within 60 days: up to $49 for sole proprietorships and $300 for corporations.

8. Secure funding for your business

Not every business needs outside funding, but if yours does, here’s where to look:

• Federal grants & financing: The Government of Canada offers grants, tax credits, wage subsidies, and financing programs specifically for small businesses.
• Ontario provincial grants: The province funds programs supporting Indigenous businesses, Northern Ontario startups, and employee training initiatives.
• Angel investors: Provide capital and sometimes mentorship in exchange for equity in your company.
• Crowdfunding: Platforms like Kickstarter, Indiegogo, and GoFundMe let you raise smaller amounts from a wider audience.

No matter which route you pursue, any business that satisfies municipal bylaws and operates within its approved scope will have a stronger case when approaching lenders or investors.

9. Obtain business licences and permits

Most businesses in Ontario need at least one licence or permit to legally operate. The easiest way to find out exactly what applies to you is through BizPal. It’s a free government tool that generates a tailored list based on your location, industry, and business activities.

A business that obtains industry-specific permits and ensures zoning compliance from day one avoids costly delays and legal headaches down the road. Keep in mind that some permits, such as location permits for photographers or event permits, may be required on an ongoing basis. Not just at startup.

10. Protect your company with business insurance

The right business insurance protects you and your corporation from liability and financial losses that could otherwise shut you down. The coverage you need depends on how your business operates. A solo consultant working from home has very different risks than a business offering public-facing services. 

The key is matching your coverage to your actual operations, not just grabbing the cheapest policy available.

Here are some options to consider when choosing what kind of business insurance your small business needs. 

• General liability insurance 
• Commercial property insurance
• Business income insurance
• Workers’ compensation insurance
• Professional liability insurance
• Data breach insurance
• Commercial auto insurance

We recommend contanting an experienced commercial insurance broker to advise you on the appropriate coverage for your business operations.

11. Build your brand presence

Your business is essentially ready to launch at this point—so it’s time to get the word out and build your customer base. Your marketing strategy will depend on your type of business and marketing budget, but there are several effective ways to connect with customers:

• Build your social media following with engaging content
• Reach customers directly with email marketing to build brand loyalty and drive sales (consider email marketing services like HubSpot or MailChimp if you’d like to outsource this)
• Use paid social media to build your following and reach your market more efficiently
• Advertise with local publications or radio stations to reach specific markets or demographics
• Participate in events to increase brand awareness (and keep an eye out for in-kind sponsorship opportunities)
• Network within your industry among local business groups and marketing and events professionals

12. Hire employees and scale your business

Growth is the goal, and at some point, you won’t be able to do it all alone. Whether that means hiring your first employee or outsourcing to freelancers, adding the right people at the right time is what takes a business to the next level.

In Ontario, you’ll need to establish WSIB coverage and ensure you’re meeting employment standards before bringing anyone on board.

But growth doesn’t always mean hiring more. Sometimes it means working smarter. Automation is equally powerful for scaling. Scheduling tools, invoicing apps, and email workflows free up your time for higher-value work.

Mistakes to Avoid when Starting a Business in Ontario

Even the most motivated entrepreneurs make avoidable mistakes early on. Here are four of the most common, along with how to sidestep them.

• Skipping the business plan
  Treating a business plan as optional is a costly mistake. Even a simple plan helps you pressure-test your idea before committing time and money.
• Mixing personal and business finances
  Blending your personal and business bank accounts creates a bookkeeping nightmare and complicates your filings with the CRA come tax season.
• Underestimating startup costs
  Business name registration, municipal business licenses, WSIB premiums, insurance, and early operating expenses add up fast. Budget for all of it upfront.
• Missing registration or licence requirements
  Operating without the proper registrations or permits puts your business at risk of fines, penalties, and legal liability that could have been easily avoided.

Ownr makes sure your registration is done correctly from day one, so you can focus on building your business.

Frequently asked questions about starting a business in Ontario

What do I need to start a business in Ontario?

To start a business in Ontario, you first and foremost need an idea for a service or product that you would like to bring to market.

Registering your small business with Ownr will help make the process simple, and provide you the peace of mind that your business is fully compliant with all legal requirements. 

How much does it cost to register a small business in Ontario?

The cost to register your small business in Ontario depends on the type of business structure you choose.

Do you need a license to operate a business in Ontario?

It depends on your exact location, business structure, and the types of business activities you conduct, but in most cases, you will require a business licence to operate. The easiest way to find out what business licences (and any additional permits) that your business requires is by using BizPal, a free service that lets you search for required permits and licences in your area.

How can I start a business with no money?

Some businesses can be started with little to no upfront cost, especially service-based work you can do from home using tools you already have, like freelance or virtual services. In these cases, your main expenses may be limited to basic registration fees. Product-based businesses typically require more funding for inventory, packaging, and marketing, so costs vary depending on what you’re launching.

What are the best businesses to start in Ontario?

The best businesses solve a problem or fill a gap in the market, and the same is true of any small business in Ontario. It’s also important that you as a business owner are interested and invested in your business idea.

How long does it take to register a business in Ontario?

It depends on your structure and method. A sole proprietorship registered online (through Ownr or Service Ontario) is typically processed the same day or within a few business days. Incorporation takes longer due to document preparation and government processing, usually 1–5 business days online and longer by mail. Registering through Ownr is generally faster than navigating Service Ontario directly.

What’s the difference between registering provincially vs. federally?

Provincial registration allows your business to operate legally within Ontario, but name protection applies only within the province. Federal incorporation registers your business name across Canada, protecting it in every province and territory from day one. Keep in mind that federally incorporated businesses operating in Ontario still need to register extra-provincially. If you plan to expand nationally, federal incorporation is worth considering from the start.

Do I need a separate business address?

It depends on your structure. As a sole proprietorship, you can legally use your home address as your registered business address in Ontario. But keep in mind that the address becomes publicly visible on business name registration records. An Ontario corporation must have a registered office address in Ontario, which can be a home address, a lawyer’s office, or a virtual office service if privacy is a concern.
