register business

Starting a business is an exciting time, but there are a few things you need to do to get your company started. Business registration is one of those things. In Ontario, businesses are incorporated under the Business Corporations Act (OBCA). Depending on your business model and goals, you can choose from three legal business structures in Ontario: sole proprietorship, partnership, or corporation.

Registering your business in Ontario is important for many reasons. For one, it ensures that your business is legal and compliant with all provincial regulations. It also allows you to open a business bank account, apply for loans and other financial assistance, and register for GST/HST. Additionally, registering your business allows you to hire employees and enter into contracts. Overall, registering your business in Ontario gives you the foundation you need to operate a successful and legal business.

The first step in registering your business is to decide on the legal structure of your business. You can choose between three legal business structures in Ontario: sole proprietorships, partnerships, and corporations.

Sole proprietorship

A sole proprietorship is a legal business structure owned and operated by one individual. This legal business structure is the most widespread. Sole proprietorships are not legally separate from their owners, which means that the owner is personally liable for all debts and obligations of the business.


A partnership is an arrangement between two or more people to carry on a business together. Partnerships are usually created by an agreement, which sets out the roles and responsibilities of each partner, as well as how profits and losses will be shared. There are two major partnership types: general partnership and limited liability partnership. 

General partnership

A general partnership is a legal entity formed by two or more co-owners who carry on a business together with the intention of making a profit. The partners share in the profits and losses of the business, and each partner has full management and control over its operations. 

Limited partnership

A limited partnership is a business arrangement in which one or more partners (the general partners) manage the business and assume all liability for its debts, while one or more other partners (the limited partners) contribute capital but do not participate in the management and cannot be held personally liable for the debts of the business.


Corporations are businesses that shareholders own. They are legally separate from their owners, which means that the shareholders are not personally liable for the debts and obligations of the business.

Deciding on the right business structure is an important decision. You should speak with a lawyer or accountant to make sure you choose the best option for your business.

Registering your business name in Ontario

Business name registration is an important part of running a sole proprietorship, partnership, or corporation in Ontario. If you decide to use your own name as your business name, you don’t have to register it. But suppose you want to use a different name for your business. In that case, you must register it with the Ontario Business Registry. In certain scenarios, you may be required to register your business name even if you are using your own personal name.

You may want to create a trade name if your personal name is difficult to pronounce or spell or if you feel that it would be advantageous for marketing purposes to have a different name associated with your business. For example, suppose your personal name is John Smith, and you own accounting business. In that case, you may want to operate under the name “Smith and Associates” or “John Smith Accounting”.

What to keep in mind when choosing your business’s name

If you want to operate under a business name in Ontario, you must register it with the province. There are a few things to keep in mind when choosing and registering your business name:

Your business name cannot be misleading. It cannot be confusingly similar to another business name or trademark. Use the Ontario Business Registry to check if your business name is already taken. You cannot use restricted words or expressions in your business name unless you get permission from the government agency that controls them. For example, you need permission from the Canadian Intellectual Property Office (CIPO) to use the word “bank” in your business name.

You may need permission from another government agency to use certain restricted words or expressions in your business name. For example, you need permission from the Ontario Securities Commission to use the word “investment” in your business name.

Business names and suffixes

Depending on your business legal form, you can choose from a different assortment of business names. For instance, if your business operates as a corporation, you will have to include suffixes such as “Corporation”, “Incorporated”, “Incorporée”, “Company”, “Limited”, or “Limitée” at the end of your corporate business name. This is required by Canada Business Corporations Act. You can also use abbreviations such as “Corp.” “Ltée.”, “Ltd.”, “Inc.”, or “S.A.R.F.”. Other restrictions apply, and you should consult an incorporation specialist or a business lawyer to ensure your desired name is available and complies with naming regulations.

You must do a trademark search to make sure it’s available if you want to register a trademark as part of your business name. You can apply for a Business Name Registration online through the ServiceOntario website. The registration fee is $60. You need to renew your business name every five years. Make sure to renew your business name within 60 days before the expiration date.

Obtaining a NUANS name report in Ontario

NUANS stands for Newly Upgraded Automated Name Search. It is a computerized system that searches for similar or identical business names. The NUANS name report is used by businesses in Ontario to help them choose a unique name for their company. NUANS report is not required for partnerships, sole proprietorships, and number-named businesses. However, if you are registering Business Corporation in Ontario, you will need to obtain a NUANS report.

The first step in the process is to find a NUANS member in Ontario. You can search them on Google, or you can search for NUANS members in the database.

There is a fee for each NUANS name report. The fee is based on the number of names that are searched. Businesses can expect to pay around $15-$50 for a single-name search, depending on how fast it will be delivered.

Obtaining a NUANS name report is the first step in incorporating a business in Ontario. Once a business has chosen a unique name, you can then proceed with the incorporation process.
