The appellant employer terminated the respondent's employment and made several termination-related payments, including a mistaken payment in November 2018.
The parties subsequently attended mediation and executed minutes of settlement requiring the employer to pay $150,000 'in addition to amounts already paid'.
The employer's representatives at mediation were unaware of the November payment and later sought to deduct it from the settlement amount.
The motion judge enforced the settlement, finding no ambiguity and no fraud by the respondent regarding the employer's unilateral mistake.
The Court of Appeal dismissed the appeal, holding that the subjective, uncommunicated knowledge of the employer's representatives did not form part of the factual matrix for contractual interpretation.
