The applicant unions sought judicial review of an interim decision of the Ontario Labour Relations Board regarding card-based certification.
The employer had provided lists of employees for two prospective bargaining units with 24 overlapping names.
The unions agreed between themselves on how to allocate the overlapping workers and argued the employer was bound by this agreement.
The Board ruled the employer was not a party to the agreement and ordered the employer to provide an unqualified list.
The Divisional Court dismissed the application for judicial review, finding the Board's decision was reasonable and consistent with its jurisprudence.
