Every business partnership eventually ends. Whether through retirement, disagreement, death, or simply a change in heart, the day will come when one or more shareholders want out of a company they helped build. How that exit unfolds depends almost entirely on what was written down before anyone wanted to leave. Buy-sell provisions represent the mechanism through which shareholders can transition out of a corporation while protecting both those who depart and those who remain. Without these provisions, an exit that should be straightforward can devolve into litigation, frozen bank accounts, and businesses that cannot function because their ownership structure has become paralyzed by conflict.
The foundation of buy-sell provisions rests on a simple principle that animates much of corporate law in Canada: shareholders in a private corporation have no inherent right to force the company or other shareholders to purchase their shares. Unlike publicly traded companies where shares can be sold on an exchange to any willing buyer, shares in a private corporation are illiquid by design. Provincial corporate statutes across Canada, including the Business Corporations Act in British Columbia, the Business Corporations Act in Alberta, the Business Corporations Act in Saskatchewan, the Business Corporations Act in Ontario, and the Canada Business Corporations Act at the federal level, all contemplate that private corporations will restrict the transfer of their shares. As of the date of authorship, these statutes uniformly allow corporations to include transfer restrictions in their articles, and most private corporations do exactly that. The result is that a shareholder who wants to sell cannot simply find a buyer and close a deal. They need either the approval of the board or existing shareholders, or they need a pre-existing agreement that creates an exit path.
