Key takeaways
  • A numbered company skips the name-search step entirely, since it never has to clear a name against the registry — one way to trim this stage if a distinctive name isn’t essential to you.
  • Even though the Ontario annual return itself carries no government fee, most businesses still pay their accountant or lawyer to prepare and file it correctly and to keep the minute book…
  • If your corporation was incorporated outside Canada and wants to carry on business in Ontario, an extra-provincial licence currently runs $330 (as of mid-2026 — verify before filing).

The government filing fee is the number most people ask about first — and it’s the smallest piece of the real cost of running a corporation. Between name searches, ongoing filings, and the accounting and legal work a corporation generates every year, the actual budget is bigger than a single line item.

This article breaks down what to expect at each stage: incorporating, keeping the corporation in good standing, and the variable costs that catch people off guard.

One-Time Costs to Incorporate

ItemApproximate fee (as of mid-2026 — verify the current amount)
OBCA incorporation (Ontario, Articles of Incorporation via the Ontario Business Registry)$300
CBCA incorporation (federal, online filing)$200
CBCA express service add-on (faster processing)+$100
Corporate name search / reportVaries by provider — not a fixed government fee
Legal fees for drafting articles, organizing resolutions, and setting up the minute bookVaries by firm and complexity

A numbered company skips the name-search step entirely, since it never has to clear a name against the registry — one way to trim this stage if a distinctive name isn’t essential to you.

Annual and Recurring Costs

ItemApproximate fee (as of mid-2026 — verify the current amount)
Ontario annual return (Corporations Information Act filing, via the Ontario Business Registry)$0
CBCA annual return (online)$12
Accounting fees for corporate bookkeeping, financial statements, and a corporate tax returnVaries — generally higher than a sole proprietorship’s personal return
Legal fees to keep the minute book current (annual resolutions, any director/officer changes)Varies by firm

Even though the Ontario annual return itself carries no government fee, most businesses still pay their accountant or lawyer to prepare and file it correctly and to keep the minute book updated alongside it — an outdated minute book is one of the most common problems that surfaces later, in financing or a sale.

Costs That Only Apply in Certain Situations

Costs That Are Easy to Underestimate

Budgeting Realistically

A rough way to think about it: the government filing fee is a one-time cost measured in the low hundreds of dollars; the ongoing legal and accounting cost of doing it properly every year is usually the larger number over time. Businesses that treat incorporation as "file once and forget it" are usually the ones facing a costly cleanup later.

Frequently asked questions

Is incorporating federally cheaper than incorporating in Ontario?

The federal (CBCA) filing fee is currently lower than the Ontario (OBCA) fee, but that’s rarely the deciding factor — director residency rules, where you’ll need to register extra-provincially, and how you want your name protected usually matter more than the fee difference.

Do I have to pay the Ontario annual return fee every year?

No — the Ontario annual return filed through the Ontario Business Registry currently carries no government fee. Most businesses still budget for their accountant or lawyer’s time to prepare and file it correctly.

Does a numbered company cost less to incorporate than a named one?

The government filing fee is the same either way. A numbered company can save money indirectly by skipping the name-search step, since there’s no name to clear.

What’s the biggest cost people forget to budget for?

Ongoing accounting and legal maintenance — bookkeeping, corporate tax returns, and keeping the minute book current — tends to add up to more over a few years than the initial incorporation fee.
