Incorporate a business in Ontario 2026 searches climb every September, because owners want their first fiscal year to line up with a clean year end.
Incorporating itself takes under an hour online. The decisions around it are what determine whether the structure helps you or creates work.
This guide covers the choice, the real cost, and the filings that catch new owners in year two.
Should you incorporate a business in Ontario 2026 at all
Incorporation gives you limited liability, a separate legal entity, and access to the small business tax rate on retained profits.
The tax advantage only bites when you leave money in the company. If you draw every dollar out to live on, you are mostly buying liability protection.
A rough test: consistent profit you do not need personally, plus contracts or clients that expect a corporation, means it is time.
Against that, budget for a corporate return, bookkeeping and an annual return every year, whether or not you traded.
Federal or Ontario: the choice that matters most
Provincial incorporation under the Ontario Business Corporations Act is the simpler route if you operate mainly in Ontario. You register once, with the province.
Federal incorporation under the CBCA gives stronger national name protection and the right to operate across Canada, but you must still register extra-provincially in each province you do business in.
Federal corporations also file an annual return with Corporations Canada and maintain a register of individuals with significant control. Details are on the Corporations Canada site.
Provincial filings run through the Ontario Business Registry.
Named or numbered, and what it really costs
A numbered company is faster and cheaper because it skips the name search. You can always register an operating name later.
A named company requires a NUANS report and a name that is distinctive, descriptive and carries a legal ending such as Inc. or Ltd.
Beyond the government fee, budget for the NUANS search, a minute book, and your first-year accounting setup. The filing fee is the smallest line on that list.
The steps in order
Choose the jurisdiction, then the name. Run the NUANS search before you fall in love with a brand.
File the articles of incorporation, setting out share classes and directors. Get the share structure right at the start, because fixing it later means a formal reorganisation.
Organise the corporation: appoint directors and officers, issue shares, adopt by-laws, and open the minute book.
Register for a business number, then for GST/HST, payroll and any provincial accounts you need.
Open a corporate bank account and stop running personal and business money through one place. Mixed accounts are the most common cause of a painful first year end.

The filings nobody warns you about
An annual return is required every year and is separate from your tax return. Missing it repeatedly can lead to dissolution.
Your minute book must stay current with resolutions, director changes and share transfers. Buyers, lenders and the CRA all ask for it eventually.
Federal corporations must also keep their significant-control register updated, with penalties for failing to do so.
The bottom line
Incorporate a business in Ontario 2026 the right way and the structure quietly does its job for a decade.
Get the jurisdiction and share structure right, keep the corporate money separate, and calendar the annual filings.
Incorporating before your year end also gives you a clean first fiscal period, which is the main reason September is the right month to do it.
