A vote taken at a meeting that never had quorum isn't a valid vote, no matter how the room felt at the time. For Ontario corporations, "quorum" is the minimum number of directors or shareholders who need to be present, or represented, before any business at a meeting counts. Getting it wrong is a surprisingly common way for otherwise well-run corporations to end up with resolutions that don't actually hold up.

This article explains what quorum means for directors' meetings versus shareholders' meetings, where the rule actually comes from, and what to do if a meeting can't reach it.

What Quorum Means and Why It's Not Optional

Quorum exists to make sure decisions made in a director's or shareholder's name reflect a genuine level of participation, not a handful of people acting without the rest of the board or ownership group even being present. If a meeting proceeds without quorum, resolutions passed at it are generally invalid, even if everyone who did show up agreed unanimously.

Where the Quorum Rule Actually Comes From

This is the part that surprises a lot of directors: quorum for an Ontario corporation isn't a single fixed number set out directly in the OBCA or CBCA. Instead, the corporation's own bylaws set the quorum requirement, within limits the statute allows. That means two Ontario corporations can have genuinely different quorum rules, and the only way to know yours is to check your own bylaws, not to assume a number that applied at a different company or that a founder half-remembers from somewhere else.

Quorum for Directors' Meetings

For a board of directors, quorum is typically expressed as a proportion of the directors currently in office, commonly a majority, though a corporation's bylaws can set it differently. A director who has resigned or been removed no longer counts toward the total.

Quorum for Shareholders' Meetings

For a shareholders' meeting, quorum is usually expressed in terms of the shares entitled to vote that are present in person or represented by proxy, again commonly a majority, but this is a bylaw setting, not a fixed statutory number. A corporation with only one or two shareholders will rarely have a practical quorum problem; the issue tends to show up more in corporations with several shareholders who don't always show up or respond.

Meetings Held by Phone or Video

Most modern Ontario corporate bylaws expressly allow directors or shareholders to participate in a meeting by telephone or video conference, and someone participating this way is generally counted toward quorum the same as if they were in the room. Older bylaws drafted before this was common practice sometimes don't address it directly, which can create unnecessary uncertainty — another good reason to have bylaws reviewed periodically rather than treated as a one-time document from incorporation.

If a Meeting Can't Reach Quorum

If not enough directors or shareholders show up, the usual options are to adjourn the meeting to a later date, often set out in the bylaws themselves, or, for many routine decisions, to proceed instead by a written resolution signed by all directors or all voting shareholders, which doesn't require a "meeting" or quorum in the same sense. This is the same written-resolution mechanism many small corporations use for their annual meeting requirement.

Frequently asked questions

Can we lower our quorum to just one director?

Often, yes — many small, owner-operated corporations do set a low quorum, sometimes just one director, in their bylaws. Whether that's appropriate depends on your specific governance needs and, if you have one, your unanimous shareholder agreement.

Do proxies count toward shareholder quorum?

Generally yes — a shareholder represented by a validly appointed proxyholder is typically counted as present for quorum purposes, but the exact mechanics should be confirmed against your bylaws and any applicable proxy rules.

What if our bylaws don't mention quorum at all?

This is a real gap worth fixing. If your bylaws are silent or unclear, it's worth having a lawyer review and update them so there's no ambiguity the next time a decision needs to be made quickly.

Does quorum have to stay the same throughout the whole meeting?

This is a common trap — if directors or shareholders leave partway through and the numbers drop below quorum, decisions made after that point can be challenged. Well-drafted bylaws address this directly.

Can a single shareholder waive quorum for their own meeting?

If that shareholder is the corporation's only voting shareholder, quorum is easy to satisfy since there's no one else whose presence is needed. Multi-shareholder corporations don't have this shortcut and need to actually meet the quorum set out in their bylaws.
