President. Secretary. Treasurer. These titles feel self-explanatory, so many small-business owners hand them out without thinking twice — often to themselves, on day one. What’s less obvious is that officer titles and authority aren’t the same thing in Ontario corporate law. A title tells the world what someone is called; it doesn’t automatically tell the world what they’re allowed to do.

This article breaks down where officer authority actually comes from, what each common title tends to carry with it, and where owners get tripped up.

Titles Aren’t Fixed by Statute — Your By-Laws Are

Neither the OBCA nor the CBCA hands corporations a mandatory list of officer titles. Instead, a corporation’s by-laws — and the resolutions its directors pass — decide what officer positions exist and what each one is authorized to do. Two corporations can use identical titles and mean genuinely different things by them.

This matters because relying on a title alone to figure out who can sign what is a common mistake. The title is a label; the by-laws and resolutions are the source of truth.

Where Authority Actually Comes From

An officer’s authority to act for the corporation generally comes from one of a few places:

  1. Actual authority — expressly granted through the by-laws or a specific board resolution (for example, "the Treasurer is authorized to sign cheques up to $X").
  2. Apparent authority — authority the corporation appears to have given someone, through how it’s held that person out to the world, even if the internal paperwork is thinner than it should be.
  3. Ordinary course of business — some acts are so routine for a given role that outsiders reasonably assume authority exists without checking the fine print.

What the Common Titles Typically Involve

TitleCommon ResponsibilitiesTypical (Not Guaranteed) Authority
President / CEOOverall management and day-to-day directionOften held out as authorized to sign ordinary business contracts
SecretaryMaintaining the minute book, records, and certifying documentsAuthority to certify true copies of resolutions; not usually financial signing authority
Treasurer / CFOFinancial oversight and banking relationshipsOften authorized for banking and financial transactions, usually within approved limits
Vice-PresidentA delegated portion of the President’s responsibilitiesWhatever’s actually delegated — often narrower than the President’s authority

None of these are legal defaults guaranteed by statute — they’re common practice, and your own by-laws or resolutions can (and should) say something more specific.

When an Outsider Can Rely on a Title

This is where things get genuinely important for a corporation’s own protection. If a corporation lets someone use a title, sign documents, or negotiate deals without correcting the impression that they’re authorized, a third party dealing with that person in good faith may be entitled to rely on that appearance — even if internal restrictions existed that the outsider never saw.

In other words, a corporation that’s sloppy about who holds themselves out as having authority can end up bound by a deal an officer was never actually supposed to make. This cuts against the corporation, not in its favour, which is exactly why authority should be documented and communicated internally, not assumed from a title.

Getting This Right in Practice

Frequently asked questions

Does every Ontario corporation need a President, Secretary, and Treasurer?

No specific titles are mandated by statute. Most corporations use these common titles by convention, but what matters legally is what the by-laws and resolutions actually authorize each officer to do, not the label itself.

Can one person hold every officer title in a small corporation?

Yes, this is common in owner-operated corporations, especially with a single director and shareholder. It doesn’t change the underlying principle that authority should still be documented, even if the same person wears every hat.

If someone signs a contract as "President," is the corporation automatically bound?

Often yes, in the ordinary course of business, because of the apparent authority a President’s title typically carries — but this isn’t automatic in every situation, particularly for unusual or high-value transactions. It’s a fact-specific question.

Do officer titles need to be reported to the government?

Officer information generally does need to be reported on the initial and annual filings made under the Corporations Information Act, but the specific internal authority attached to a title is a private, internal matter set out in your by-laws and resolutions, not something the registry records.
