Everything You Need to Know About Starting a Consulting Business in Ontario

If you're considering starting a consulting business in Ontario, you're in for an exciting journey of entrepreneurship. Consulting offers the opportunity to leverage your expertise and provide valuable services to clients in need. However, embarking on this venture requires careful planning and a clear understanding of the regulatory landscape in Ontario. In this guide, we will walk you through the key aspects of starting and operating a consulting business in this province.

What's Different About Starting a Consulting Business in Ontario?

Ontario, as Canada's most populous province and a major economic hub, offers a unique business environment for consultants. With a diverse and thriving economy, Ontario provides ample opportunities for consultants to work with a wide range of clients across various industries. The province's key sectors include technology, finance, healthcare, and manufacturing, among others. As a consultant in Ontario, you'll have the chance to tap into this market and make a significant impact on businesses and organizations.

You’ll also need to keep in mind certain provincial differences and regulatory requirements to start and manage your business in the long run.

Registering Your Business in Ontario

Before launching your consulting business in Ontario, you must follow the necessary legal and administrative steps to register your business. The first step is to choose a business name and ensure its availability. Register your business name with the Ontario government and obtain the relevant permits and licenses, if applicable to your consulting services. You'll also need to decide on your business structure, such as sole proprietorship, partnership, corporation, or limited liability partnership (LLP), each with its advantages and considerations.

Tax Obligations in Ontario

Understanding and fulfilling your tax obligations is crucial for running a consulting business in Ontario. As a consultant, you'll need to register for a Business Number (BN) with the Canada Revenue Agency (CRA) and register for a Harmonized Sales Tax (HST) account, if your annual revenue will exceed the $30k annual sales threshold. Accurate record-keeping of your business expenses, income, and HST collected is essential to facilitate your tax filings, and make your life a lot easier during tax season! You may want to open a business bank account to help keep your personal and business finances separate, and make bookkeeping a lot easier.

To maximize your tax deductions, keep meticulous records of business-related expenses, such as office supplies, travel costs, professional development, and home office expenses. By doing so, you can effectively reduce your taxable income and optimize your tax savings.


In conclusion, starting a consulting business in Ontario offers a wealth of opportunities for consultants to thrive in a diverse and bustling marketplace. By understanding the unique business landscape in Ontario, fulfilling the necessary registration and tax obligations, and leveraging the right accounting tools, you can embark on a successful journey of entrepreneurship and build a thriving consulting practice.
