What happens if a minority shareholder inherited their shares and has no relationship with the other owners?

Inheriting shares generally makes someone a shareholder with the same rights as anyone else who holds shares of that class — notice of meetings, voting rights, access to relevant financial information, and the ability to invoke Ontario's oppression remedy under the Business Corporations Act if the company's affairs are conducted in a way that unfairly disregards their interests — regardless of whether they have any personal relationship with the other owners.

In practice, this can create friction: the remaining owners may be used to operating informally among themselves and less prepared to deal with a shareholder who has no history with the business and may ask more questions or expect more formal communication. If the shareholders' agreement includes transfer restrictions, right-of-first-refusal provisions, or a mechanism for buying out an inheriting shareholder, those terms should be reviewed to see whether they offer either side a path to resolve the situation. An inheriting shareholder unfamiliar with the business is well advised to get their own legal and financial advice early.
