Once you decide to incorporate your business, a second question lands almost immediately: do you incorporate federally with Corporations Canada, or provincially under Ontario law? Both give you a separate legal entity with limited liability and the same access to the small business tax rate, so the choice is less about tax and more about name protection, cost, and how much annual paperwork you are willing to carry. If you are weighing the options for incorporating in Ontario, this guide walks through the practical differences so you can pick with confidence rather than guessing.
What incorporating actually gives you
Whichever route you take, incorporation creates a corporation that is legally separate from you. That separation is the point: the corporation signs contracts, owns assets, and owes debts in its own name, which shields your personal assets in most situations. It also opens the door to tax planning that sole proprietors cannot use, including the small business deduction, income deferral, and paying yourself through some combination of salary and dividends.
Here is the part that surprises many owners: the jurisdiction you choose does not change your income tax outcome. A federal corporation and an Ontario corporation operating in Ontario file the same T2 corporate return, pay the same combined federal-provincial corporate tax rates, and qualify for the same small business rate on active business income. The federal-versus-provincial decision is an administrative and branding decision, not a tax-savings one.
Name protection: the biggest real difference
The most meaningful distinction is how far your corporate name is protected. A federal corporation receives name protection across Canada. Corporations Canada reviews your proposed name against a national database and, once approved, no one else in the country can incorporate under a confusingly similar name. If your brand matters and you might expand beyond Ontario, that nationwide shield is valuable.
An Ontario corporation's name is protected only within Ontario. The province does not pre-clear your name against other jurisdictions in the same way, and someone in another province could register something similar. For a local trade or a numbered company, that is often perfectly fine. For a business building a recognizable brand, it can be a real limitation.
Named versus numbered
In both jurisdictions you can skip the name search entirely and take a numbered company, such as "1234567 Canada Inc." or "1234567 Ontario Inc." It is faster and cheaper, and you can always register a business (trade) name to operate under. If you do want a word name, you will need a NUANS name search report to check availability before filing.
Cost: filing fees and the ongoing bill
Government filing fees are modest and should not drive the whole decision, but they are worth knowing. As of 2026, incorporating federally online with Corporations Canada costs $200. Incorporating provincially through the Ontario Business Registry costs $300 online. On the surface, federal looks cheaper.
The ongoing costs tell a fuller story. A federal corporation must file an annual return with Corporations Canada every year, which costs $12 online and is separate from your tax return. A federal corporation carrying on business in Ontario also has to register in Ontario, adding a step. An Ontario corporation files its annual return alongside its T2 corporate tax return, so there is one less standalone filing to remember. None of these amounts are large, but the federal route carries slightly more moving parts to keep track of year after year.
- Federal filing fee: $200 online to incorporate.
- Ontario filing fee: $300 online to incorporate.
- Federal annual return: $12 each year, filed with Corporations Canada.
- NUANS report: an added cost if you want a word name rather than a number.
Choosing between federal and Ontario incorporation is rarely about tax; it is about how far your name reaches and how much paperwork you want to shoulder.
The paperwork and where you can operate
A federal corporation is incorporated under the Canada Business Corporations Act, but incorporating federally does not automatically let you operate everywhere. If your federal corporation carries on business in Ontario, you must still register it extra-provincially in Ontario. The good news is that this Ontario registration for a federal corporation is now handled through the Ontario Business Registry and is generally straightforward. If you later expand into other provinces, you would register in each of those as well.
An Ontario corporation lives entirely within one system. There is no second federal layer and no extra-provincial registration unless and until you start carrying on business in another province. For an owner who wants the simplest possible compliance footprint and expects to stay Ontario-focused, that single-jurisdiction simplicity is a genuine advantage.
Directors and residency
Residency rules have loosened over the years. Ontario removed its Canadian-resident director requirement in 2021, so an Ontario corporation no longer needs a resident Canadian on its board. Federal corporations under the CBCA still require at least 25% of directors to be resident Canadians (or one, if you have fewer than four). If your board includes non-residents, this rule can tip the decision toward Ontario.
So which should you choose?
There is no universally correct answer, but a few patterns hold up well. Federal incorporation tends to suit businesses that want nationwide name protection, plan to operate or expand across provinces, or care about the prestige of a federal charter. Ontario incorporation tends to suit local businesses that will stay within the province, owners who want the leanest yearly compliance, and boards that include non-resident directors.
- Lean toward federal if your brand name is central and you might grow beyond Ontario.
- Lean toward Ontario if you are staying local and want a single set of filings.
- Either works for a numbered holding company or a straightforward local operating business.
Whatever you choose, set up your corporation correctly from day one: a clean share structure, a proper minute book, and a plan for how you will pay yourself. Fixing structural mistakes after the fact is far more expensive than getting it right at incorporation.
Key takeaways
- The federal-versus-Ontario choice does not change your corporate tax rate; both pay the same and access the small business deduction.
- Federal gives Canada-wide name protection; Ontario protects your name only within the province.
- Federal costs $200 to file plus a $12 annual return; Ontario costs $300 with the annual return folded into your T2.
- A federal corporation operating in Ontario must still register extra-provincially in the province.
- Federal corporations need at least 25% resident-Canadian directors; Ontario has no residency requirement.
- A word name needs a NUANS search; a numbered company skips it and is faster.
