Registering a business all on your own can be stressful, time-consuming, and downright confusing. Luckily, you don’t have to do it alone!

What is a sole proprietorship in Canada?

A sole proprietorship is the simplest business structure in Canada, in which an individual owner of a business takes on all the profits, debts, and legal responsibilities of a company. Sole proprietorships are taxed at your personal income tax rates, and are also the least expensive and most straightforward business types in Canada when it comes to both registration and ongoing requirements.

Do I need to register a sole proprietorship in Ontario?

In most cases, you are legally required to register a sole proprietorship in Ontario. The one exception is if you are conducting business operations under your own legal name, rather than a distinct business name, in which case registering your business is not mandatory. 

That said, registering your sole proprietorship may still be in your best interest, even if it’s not technically necessary. While establishing a sole proprietorship does not provide business name protection, having a registered business can lend a level of validity to your business that you don’t get with an unregistered company. 

Sole proprietorship registration also gives you the option of opening a business bank account, and can help with accessing government programs for business loans and other funding opportunities.

A sole proprietorship is also the easiest type of business to register, and considering how complicated starting a business can be, the comparatively stress-free sole proprietorship registration definitely has its share of advantages.

How to register a sole proprietorship in Ontario

Determine if a sole proprietorship is right for you

Becoming a sole proprietor can be the perfect business structure if you’re running a small business by yourself and don’t want to have to worry about complex corporate paperwork or expensive accounting fees. As a sole proprietorship, you can file your small business income and deduct business expenses as part of your personal taxes.

If you’re considering running your business with a partner, you’ll need to look into registering a partnership rather than a sole proprietorship. While a simple verbal agreement is enough to form a partnership, it’s always a good idea to lay out your business strategy in a partnership agreement. One of the advantages of a partnership is another person to bounce ideas off of, but it can lead to challenges when the roles of the partners are not clear.

On the other hand, if additional liability protection is a priority, incorporation may be the best choice for your business.

Register your business name

As we mentioned earlier, you aren’t required to register as a sole proprietorship if you’ll be doing business under your legal name. However, if you want to use a more creative name for your business, you’ll need to register your business name.

The Business Names Act of Ontario dictates that a registered sole proprietorship name is not protected from being used by another business, which means that multiple sole proprietorships could end up operating under the same name. While this is allowed, it makes sense to set your business apart (and make sure it shows up first in search engine results) by choosing a unique business name. You may also want to find out if the associated domain name is available at this stage.

When you register your sole proprietorship with Ownr, you’ll get up to ten free NUANS name searches to find out if the business name you have in mind is already taken. 

Fill out the paperwork

Now comes the part everyone loves – the forms. Luckily, a sole proprietorship is the easiest type of business to register, and you can complete the entire sole proprietorship business registration process online.

Once you’re ready to register your sole proprietorship, you’ll need to create a ONe-key account and a Service Ontario account. Then you’ll be able to log into your Service Ontario account and register your business for a fee of $60.

If you want to save money, time, and effort, you can register your sole proprietorship with Ownr for a one time full registration fee of only $49. You’ll also gain access to a ton of great perks and resources, including $100 back when you open an RBC business bank account within 60 days of registering with Ownr.

Ownr also keeps all your business information in one convenient location so you don’t have to tear your hair out wondering where the file is with your business registration information when you’re hiring a new team member, opening a business bank account, or applying for a business loan or credit card.

Register for a GST or HST number

Finished registering your business? Don’t pat yourself on the back for a job well done just yet — there are still a few more things to do! Most businesses in Ontario are required to register for the GST/HST, especially if you make more than $30,000 in annual revenue. If you meet the criteria to charge and remit sales taxes, you’ll need to apply for a GST/HST number online through the Canada Revenue Agency’s Business Registration Online (BRO). You can also register by mail, fax, or telephone.

Even if you don’t make over $30,000, you might still want to get a GST/HST number, since registering for GST and HST will allow you to claim input tax credits against your business income. Essentially, you’ll get to deduct the GST or HST from things you buy for your business.

Pro tip: you may also need to register for other business licences or certifications depending on your business, like health and safety permits required by the health department. BizPal is a government service that can help you figure out what licences and permits you may need.
