The complainant filed a jurisdictional dispute regarding the installation of site services at a plant building project.
The Board was asked to make a preliminary determination under section 150 of the Labour Relations Act as to whether the work fell within the industrial, commercial and institutional sector.
The complainant argued that the Board should consider area practice in making this determination.
The Board held that the concepts of area practice and geographic area have no basis in the statutory definition of 'sector' in section 117(e), which is determined by work characteristics.
The Board directed that the matter be listed for continuation of hearing to entertain evidence of work characteristics.
