Reserved matters and investor veto rights

An investor deciding how much control to negotiate is really choosing a point on a spectrum the CBCA itself defines: leave the board fully in charge, take over its powers entirely, or carve out a specific list of decisions that require consent. The Act ties the liability that comes with each choice directly to how much power is actually restricted.

Key takeaways

  • • The statutory default, under CBCA s.102(1), is that “the directors shall manage, or supervise the management of, the business and affairs of a corporation” — subject only to a unanimous shareholder agreement.
  • • A CBCA s.146 unanimous shareholder agreement can restrict that authority “in whole or in part” — a full takeover of the board's powers is only one end of the range it permits.
  • • Under s.146(5), liability shifts “to the extent that” power is restricted — a narrow, negotiated veto list carries proportionally narrower director-style liability than a full USA, not the same exposure.
  • • s.189(3) already requires shareholder approval for a sale of “all or substantially all” of the corporation's property outside the ordinary course — the statutory floor a negotiated reserved-matters list is built on top of, not a substitute for.

The default: directors run the company

s.102(1) states the baseline in one sentence: “Subject to any unanimous shareholder agreement, the directors shall manage, or supervise the management of, the business and affairs of a corporation.” Absent anything more, an investor who is not a director has no say in any operating decision, however large, short of the narrow list of matters the Act itself already reserves to a shareholder vote — s.189(3)'s sale of substantially all the corporation's property being the clearest example.

The maximal override: a full unanimous shareholder agreement

s.146 lets shareholders go the other direction entirely. A written agreement among all the shareholders that restricts the directors' powers “in whole or in part” is a valid unanimous shareholder agreement, and s.146(5) is explicit about what that costs: “to the extent that” the agreement restricts the directors' powers, the shareholders who are given that power “have all the rights, powers, duties and liabilities of a director” over it — and the directors are relieved of it to the same extent. Taking over board-level control is not free. It comes with board-level exposure, proportional to exactly how much power changed hands.

The narrower tool most investors actually want

Most negotiated protection does not go anywhere near a full USA. A reserved-matters or veto-rights clause instead lists specific categories of decision — a new issuance of shares, debt above a negotiated threshold, a transaction with a director or an affiliate, approval of the annual budget, executive compensation — that require investor consent before the board can act, while leaving day-to-day management with the directors. It is a restriction “in part,” in s.146's own language, which is precisely the category the section anticipates alongside a full takeover.

The liability point most negotiations miss

Because s.146(5) ties liability to “the extent that” power is restricted, an investor holding a veto over three specific categories of decision does not automatically take on the same personal exposure as a director managing the whole business. The director-style duty and liability attaches to the restricted powers themselves, not to the investor generally. That matters directly to how the clause should be scoped: a longer reserved-matters list is not free protection, and each additional category added to it is, on the wording of s.146(5), an additional slice of director-style responsibility for the person holding the veto over it.

Where the statutory floor already requires a vote

s.189(3) already requires shareholder approval for “a sale, lease or exchange of all or substantially all the property of a corporation other than in the ordinary course of business,” and s.189(6) gives every share a vote on that question “whether or not it otherwise carries the right to vote.” The default voting threshold for most major corporate acts is the “special resolution” defined in s.2(1) — two-thirds of the votes cast, or unanimous written consent. A majority bloc large enough to clear two-thirds does not need an investor's agreement at all under that default; a negotiated reserved-matters list is what gives a minority investor a say below the statutory supermajority threshold, on a list of matters the investor themselves chose rather than the Act's own list.

A list of categories is not a fixed template

There is no statutory or published-standard list of what belongs in a reserved-matters clause — it is negotiated case by case, and the categories above are the ones that recur in practice rather than a required set, which is exactly why an incoming buyer needs to read the existing list rather than assume it. A dollar threshold left vague as “material” expenditure invites exactly the same fight a missing valuation formula does: everyone agrees a veto exists, and nobody agrees whether the disputed decision was big enough to trigger it. Naming a specific number, and revisiting it as the company grows, keeps the clause doing its job instead of becoming its own source of disagreement.

Paired with information rights

A veto is only as good as the information behind it. An investor who learns about a problem after the board has already acted has a technical breach claim, not a working veto; see information rights for a minority investor for the reporting clause most negotiations pair alongside the reserved-matters list.

A veto list, and what happens when the board ignores it

An investor negotiates a USA-style veto, restricted in part under s.146, over three categories: any single expenditure over a negotiated threshold, any new debt facility, and any transaction with a director or their family. These are the investor's own negotiated categories, not a statutory or market-standard list.

The board approves an equipment purchase above that threshold without asking. Two consequences follow from the statute's own wording, not from general principle: first, the purchase falls inside a power the USA restricted “in part,” so the board's unilateral approval is outside its remaining authority under s.102(1) and is challengeable on that basis; second, because the investor was “given” that specific power under s.146(1), s.146(5) attaches director-style duty and liability to the investor for that category of decision — and only that category, not the business generally.

Common questions

Does giving an investor veto rights over major decisions turn them into a director with the same personal liability?

Only over the specific decisions the veto covers. Under CBCA s.146(5), director-style duties and liability shift 'to the extent that' the agreement restricts the board's powers -- a narrow reserved-matters list carries proportionally narrow exposure, not the full liability a director managing the whole business would carry.

Is a reserved-matters list the same thing as a full unanimous shareholder agreement?

A reserved-matters list is a form of unanimous shareholder agreement under CBCA s.146, which explicitly permits restricting the directors' powers 'in whole or in part.' A full USA restricts everything; a reserved-matters list restricts only the named categories, leaving the rest of the board's day-to-day authority under s.102(1) untouched.

Do investor veto rights replace the CBCA's own shareholder-approval requirement for major asset sales?

No. CBCA s.189(3) already requires a shareholder vote on a sale of all or substantially all of the corporation's property outside the ordinary course of business, regardless of any negotiated veto list. A reserved-matters clause typically extends protection well beyond that statutory floor -- smaller transactions, debt, related-party dealings -- rather than duplicating it.
