Unanimous Shareholder Agreement (Quebec)

A Quebec unanimous shareholder agreement (convention unanime des actionnaires or CUA) is a powerful and uniquely Quebec corporate governance instrument established under article 214 and following of the Loi sur les sociétés par actions du Québec (LSAQ, RLRQ, chapitre S-31.1). Unlike ordinary shareholder agreements which bind only their signatories, a CUA is recognized as having quasi-constitutional status within a Quebec corporation because it can restrict or entirely withdraw the powers of the board of directors and redistribute those powers to the shareholders themselves. The defining characteristic that makes an agreement a unanimous shareholder agreement is the requirement of article 214 LSAQ that it be concluded between ALL shareholders of the corporation, including holders of shares that carry no voting rights. If any shareholder — regardless of how small their stake — does not sign the agreement, it cannot qualify as a unanimous shareholder agreement under the LSAQ and will not have the special legal effects described below. The CUA occupies a unique and privileged position in Quebec corporate law. First, it binds the corporation itself as a party to the governance arrangement. Second, under article 215 LSAQ, it automatically binds any person who subsequently acquires shares of the corporation, without requiring that future shareholder to sign or otherwise formally agree to the CUA — an extraordinary exception to the general principle of Quebec contract law under which only parties who sign a contract are bound by it. To protect future shareholders from inadvertently becoming bound by unknown obligations, the law requires that the existence of the CUA be declared to the Quebec enterprise registrar and that a notice of its existence appear on every share certificate or share confirmation document issued by the corporation. Third, and perhaps most importantly, shareholders who assume powers previously held by directors under the CUA also assume the same personal liability as directors for the exercise of those powers, pursuant to article 215 LSAQ. This is a critical consideration for shareholders who use the CUA to take direct control of the corporation's operations. The substantive content of a CUA is extremely flexible. It commonly includes restrictions on the board's financial powers (requiring shareholder approval for borrowing, major expenditures, and significant contracts), share transfer restrictions including rights of first refusal, drag-along rights (sortie forcée), and tag-along rights (sortie conjointe), dividend policies, shareholder financing obligations, non-competition and confidentiality obligations for shareholders, mechanisms for resolving deadlocks and governance disputes, provisions governing the appointment and removal of officers, rules for the admission of new shareholders and the handling of share transfers upon death, disability, or departure, and procedures for amending or terminating the CUA itself. The CUA is an essential governance tool for closely held Quebec corporations, particularly those with two or three founders who need a clear framework for decision-making, dispute resolution, and the protection of minority shareholders. Its strength lies in its mandatory binding effect on all current and future shareholders, making it far superior to an ordinary shareholder agreement for establishing durable corporate governance rules.

A unanimous shareholder agreement is needed in Quebec whenever the shareholders of a corporation wish to establish clear and binding rules for corporate governance that go beyond what is provided by the LSAQ's default rules, and particularly when those rules need to bind both the corporation and any future shareholders. The CUA is most essential for closely held corporations with a small number of shareholders — typically two to five founders or co-owners — who need a comprehensive framework governing their relationship, decision-making powers, exit rights, and dispute resolution procedures. Founders of startups and technology companies need a CUA when they want to ensure that major decisions about the company's direction, financing, and strategic partnerships require the consent of all co-founders rather than being made unilaterally by a majority. This is particularly important in the early stages of a business when the founders' trust in each other is high but the legal framework for their relationship is often underdeveloped. Family businesses in Quebec frequently use CUAs to establish governance rules for the transition of ownership between generations, defining which family members have decision-making authority, how shares can be transferred within and outside the family, and what happens upon the death, disability, or departure of a key family shareholder. Professional corporations — including dental clinics, medical corporations, and professional services firms — use CUAs to define the rights of the professional shareholders, establish income distribution policies, and protect each professional from the unauthorized transfer of shares to non-qualified third parties. Private equity investors and venture capital firms regularly require a CUA or similar instrument as a condition of their investment in a Quebec corporation, as it gives them contractual protections such as anti-dilution rights, information rights, approval rights over major decisions, and exit rights (tag-along, drag-along) that are not available under the LSAQ's default rules. Real estate holding corporations owned by multiple investors need CUAs to define each investor's contribution obligations, profit distribution policies, decision-making authority for property management and disposition, and exit mechanisms when an investor wishes to sell their interest. Joint ventures structured as corporations — where two or more businesses collaborate through a jointly owned subsidiary — require a CUA to define each parent company's rights and obligations, the governance structure of the joint venture, and the conditions under which the joint venture may be wound up or one party's interest acquired by the other. The CUA is also needed whenever the shareholders of a Quebec corporation want to supplement or replace the statutory governance framework with custom rules — for example, requiring supermajority or unanimous approval for decisions that would otherwise be within the board's exclusive authority, establishing a formal dividend policy enforceable against the corporation, or creating binding obligations of non-competition and confidentiality that are enforceable against all current and future shareholders.

The key elements of a Quebec unanimous shareholder agreement include several essential provisions that distinguish it from an ordinary shareholder agreement and ensure it achieves its governance objectives under the LSAQ. First, the agreement must be signed by ALL shareholders of the corporation, including holders of non-voting shares — this is the fundamental requirement for unanimity under article 214 LSAQ. The CUA should identify the corporation by its legal name, NEQ number, and registered office address, and list each shareholder with their shareholding details. Second, the restriction of board powers is the defining substantive feature of the CUA. The agreement must clearly specify which powers are being restricted or withdrawn from the board and reserved to the shareholders, the approval thresholds required for different categories of decisions (simple majority, supermajority, or unanimity), and whether any powers are entirely removed from the board. Third, a list of reserved decisions that require shareholder approval — such as issuance of new shares, borrowing above a threshold, major contracts, asset sales, annual budget approval, and appointment of officers — must be exhaustive and clearly drafted to avoid ambiguity. Fourth, share transfer restrictions are critical for maintaining control over the shareholder base. These typically include a right of first refusal (droit de premier refus) requiring a selling shareholder to offer their shares to existing shareholders before selling to a third party, drag-along rights allowing majority shareholders to compel minority shareholders to join a sale to a third party, and tag-along rights protecting minority shareholders by allowing them to co-sell on the same terms as majority shareholders. Fifth, the dividend policy clause establishes a binding framework for distributing profits that cannot be modified by the board alone, protecting minority shareholders' rights to participate in the corporation's financial success. Sixth, the deadlock resolution mechanism is perhaps the most practically important provision in the CUA, providing a structured process for resolving situations where shareholders with equal or near-equal voting power cannot reach required decisions. Common mechanisms include stepped escalation (negotiation, then mediation, then arbitration), the shotgun buy-sell clause, or other creative solutions tailored to the specific shareholders. Seventh, non-competition and confidentiality obligations create binding duties that apply to all current and future shareholders, preventing a departing shareholder from immediately competing against the corporation or disclosing its proprietary information. Eighth, the amendment procedure — requiring unanimous written consent of all shareholders — ensures that the CUA's core protections cannot be changed without the agreement of every shareholder. Ninth, a notice of the CUA's existence must appear on all share certificates and the CUA must be declared to the Quebec enterprise registrar under the Act respecting the legal publicity of enterprises (RLRQ, chapitre P-44.1). Finally, a bonne foi clause under article 1375 C.c.Q. and a dispute resolution mechanism specifying mediation, arbitration, or court proceedings complete the essential framework of the convention unanime des actionnaires.
