The applicant union sought judicial review of an arbitration award that dismissed its grievance regarding the respondent employer's decision to close its Windsor plant.
The union argued that the plant closure violated a 'sole sourcing' promise made by the employer in exchange for wage concessions.
The Divisional Court found the arbitrator's decision unreasonable because it relied on an improper inference drawn from rejected proposed contract language, failing to consider the overall context of the negotiations.
The application was granted, the arbitrator's decision was quashed, and the grievance was remitted back to the arbitrator for a fresh determination.
