Shareholders' Agreement

Definition

A shareholders' agreement is a private contract among the owners of a corporation that sets out how the corporation will be governed, how shares can be transferred, and what happens on the exit, death, or disability of a shareholder. A unanimous shareholders' agreement (USA) under CBCA s.146 (or BCBCA s.137, OBCA s.108) goes a step further: it can override parts of the governance default rules and shift specified director powers to the shareholders. Even a single-shareholder corporation benefits from a simpler version that addresses succession on death or incapacity.

Key rules

• Control provisions: who can nominate directors, what decisions require unanimous or super-majority approval, and how deadlock between shareholders is resolved.
• Transfer restrictions: rights of first refusal, drag-along and tag-along rights, pre-emptive rights on new issuances, and permitted transfers to family trusts or holding companies.
• Exit mechanisms: shotgun clauses, buy-sell provisions, valuation formulas (often based on a capped multiple of EBITDA or a third-party appraisal), and life-insurance-funded buyouts on death.
• Confidentiality, non-compete, and non-solicitation covenants that bind each shareholder personally for a defined period after they cease to be a shareholder.
• Interaction with the articles and by-laws: if the articles say one thing and the shareholders' agreement another, the articles generally prevail on matters of corporate existence and share attributes, but a unanimous shareholders' agreement can override matters relating to director powers.

Example

Two co-founders in a BC SaaS corporation each hold 50% of the voting common shares. A shareholders' agreement typically includes:

Without these clauses, a 50/50 corporation can become operationally frozen at the first real disagreement, and the surviving founder on a death can face a lawsuit from the deceased's estate.

Common mistakes

• Relying on the articles and by-laws alone. They address corporate existence and share attributes, but they do not cover transfer restrictions, deadlock, or exit.
• Treating the agreement as boilerplate. A buy-sell clause with a valuation formula that has not been pressure-tested can destroy value when it is triggered.
• Forgetting the single-shareholder case. If the owner dies without a plan, the estate may be unable to sign corporate documents, pay suppliers, or make payroll for weeks.
• Layering US-style SAFE or convertible-note documents onto a Canadian CCPC without checking how they interact with the existing share structure, the CCPC status, and TOSI.
• Letting the agreement drift out of sync with the minute book. Each issuance, transfer, or redemption must be recorded in both the minute book and the T2 Schedule 50.
