The union brought a motion to declare a 2004 settlement agreement of no force and effect, arguing it had been frustrated.
The settlement provided the grievor with 130 sick days upon the cessation of his WSIB benefits.
The grievor's condition deteriorated, and his WSIB benefits were locked in until age 65, meaning he would likely never access the sick days.
The union argued this was a supervening event that frustrated the contract.
The employer raised a preliminary objection, arguing the Board lacked jurisdiction to interfere with a settled matter and that the doctrine of frustration did not apply.
The Vice-Chair agreed with the employer, finding that the continuation of WSIB benefits could reasonably have been contemplated by the parties and that performance of the contract was not strictly prevented.
The union's motion was dismissed, and the settlement remained intact.
