Business registration in Ontario is rarely a single form. A new business usually deals with the province, sometimes the federal government, the Canada Revenue Agency and the Workplace Safety and Insurance Board, each with its own numbers and its own timing. Infoetax helps people in Hamilton and the GTA with the registrations and paperwork on this page: business registration, Federal and Ontario incorporation, the CRA business number, HST, payroll and WSIB registration.
We help with the filings, not the legal decisions behind them. Questions about personal liability, shareholder agreements or how shares should be split belong with a lawyer. What follows is general information to help you see the whole picture before you start.
Sole proprietorship, partnership or corporation
A sole proprietorship is the simplest structure. In law you and the business are the same person, and business income is reported on your own personal return. Ontario’s business name rules generally apply when you trade under a name other than your own legal name, and those names are registered through the Ontario Business Registry. A business name registration expires every five years, so it has to be renewed to stay current.
A partnership is two or more people carrying on a business together. General partnerships, limited partnerships and limited liability partnerships are registered through the same provincial registry, each with its own form.
A corporation is a separate legal person. It owns its own assets, signs its own contracts and files its own T2 corporate return every year, which is where our corporate tax return service comes in. Corporations also file an annual return with the province through the registry.
Ontario or federal incorporation
An Ontario corporation is formed through the Ontario Business Registry. You can choose a word name, which generally has to be supported by an Ontario NUANS search report, or a numbered name assigned when the articles are filed.
A federal corporation is formed with Corporations Canada. Its steps include choosing a name or a number, preparing articles of incorporation, setting a registered office and a first board of directors, and filing information on individuals with significant control. A federal corporation that carries on business in Ontario generally has to register in the province as well, and Corporations Canada suggests confirming that step directly with Ontario.
Which route suits you is a business and legal question we can’t answer for you, but we can walk you through what each one involves on paper. Our guide on how to incorporate in Ontario sets out the steps in more detail.
The CRA business number and its program accounts
The CRA identifies a business by a nine-digit business number (BN). When the business registers for a CRA program, a two-letter program identifier and a reference number are added to that BN. The three most new businesses meet are:
- RT for GST/HST, used once the business collects HST.
- RP for payroll deductions, used by employers and other payers of employment amounts.
- RC for corporation income tax, used by incorporated businesses.
According to the CRA, a corporation formed federally or in Ontario receives its BN and its RC account as part of incorporating. An unincorporated business only needs a BN when it registers for a CRA program account. The nine-digit Ontario Business Identification Number that ServiceOntario issues is a different number from the CRA business number, which surprises a lot of people.
The order things usually happen in
Every business is different, but registrations tend to fall in a familiar sequence:
- Settle on a structure, with legal advice where you need it.
- Register the business name, or incorporate provincially or federally.
- Get a CRA business number, which a new corporation receives automatically.
- Open a GST/HST account when the business must register or chooses to. See HST reporting for how the small supplier threshold works.
- Open a payroll account before the first payday. Our payroll services page covers what follows.
- Register with the WSIB if your industry is covered. The WSIB says employers have 10 calendar days from hiring their first employee, and our WSIB reporting page explains the ongoing side.
- Set up the books from day one, which is where bookkeeping and accounting fits.

Questions people ask
Do I have to register my business in Ontario?
It depends on the structure and the name. Corporations are registered when they incorporate, and sole proprietors and partnerships generally register a business name when they trade under a name other than the owners’ own names. The Ontario Business Registry pages on ontario.ca set out the rules, and we can help with the registration itself.
Is my Ontario Business Identification Number the same as a CRA business number?
No. ServiceOntario issues a nine-digit Ontario Business Identification Number, and the CRA issues its own nine-digit business number. They are separate numbers used by different governments.
Does a new corporation need to apply for a business number?
The CRA says a corporation formed federally or in Ontario receives a BN and a corporation income tax (RC) account when it incorporates. GST/HST and payroll accounts are added to that BN separately when they are needed.
Should I incorporate federally or in Ontario?
That is a legal and business decision, and a lawyer is the right person to advise on it. We can explain what each route involves on paper and help with the incorporation paperwork once you have decided.
Do I need to register for HST as soon as I start?
Not always. The CRA’s small supplier rule generally lets a business stay unregistered until its taxable sales pass $30,000, although many businesses choose to register voluntarily. Talk to us about your own situation before deciding.
