One of the most common questions we receive at Ontario Business Central is, ‘How do I dissolve my Sole Proprietorship?’ Many entrepreneurs ask this when they decide to close their business or transition to a different structure. It’s important to understand the process to meet all necessary requirements and avoid any future liabilities.
Understanding a Sole Proprietorship
Before you begin, it’s important to understand what a Sole Proprietorship is. A Sole Proprietorship in Ontario is a business structure that consists of one owner who has registered a business name with the provincial government. This structure is the simplest form of business ownership, offering ease of setup and straightforward management. However, it also comes with unlimited liability, meaning that the owner is personally responsible for all debts and obligations of the business.

Unlike incorporated businesses, where the business entity is separate from the owner, a Sole Proprietorship is directly tied to the individual. This distinction is important when considering how to dissolve the business.
Canceling the Sole Proprietorship When You Will No Longer Be Operating the Business
If you have decided to close your business and will no longer be operating under the registered name, you need to cancel your Sole Proprietorship registration. The process involves submitting a cancellation request to the Ontario government, which changes the status of your business name from “active” to “canceled” within the public record. It’s important to note that while the business name is no longer active, it remains in the public record as a canceled registration. This means that your business name will still be searchable, but it will be listed as a previously operational entity.
Switching to an Incorporated Business & Canceling the Sole Proprietorship
If you are transitioning from a Sole Proprietorship to an incorporated business, you will also need to cancel your Sole Proprietorship registration. Incorporating your business creates a separate legal entity, which means your business operations will now fall under the newly formed corporation. As part of this transition, canceling the Sole Proprietorship ensures that your business name is no longer registered under your personal name but under your corporation.
Canceling the Sole Proprietorship is straightforward and makes sure that there is no confusion between the old and new business structures. Once your Sole Proprietorship is canceled, you can fully operate under your new corporation, enjoying the benefits of limited liability and a separate legal identity for your business.

Information Required to Cancel a Sole Proprietorship
To cancel your Sole Proprietorship registration in Ontario, you’ll need to provide the following information:
- Business Name: The registered business name that you want to cancel.
- Business Identification Number (BIN): This is the unique identifier assigned to your business by the government when you initially registered. If you’re unsure of your BIN, Ontario Business Central can assist in retrieving it for you.
- Owner’s Information: The full legal name and address of the sole proprietor.
The process is relatively straightforward and does not require providing a reason for cancellation, specifying a cancellation date (as it is automatically done on the day of filing), or a signature.
