This case concerns an appeal from an arbitration award.
The applicants appealed an arbitrator's decision that found the respondent was entitled to 50% of corporate shares based on proprietary estoppel.
The court granted leave to appeal and set aside the arbitrator's award.
The court held that proprietary estoppel in Ontario is currently limited to interests in land and cannot be extended to other forms of property, such as shares, by an arbitrator.
Furthermore, the court found that the email on which the proprietary estoppel claim was based was internally inconsistent, ambiguous, and conditional, thus failing to meet the requirement for a clear and unequivocal promise.
The respondent's claim was dismissed.
