The applicant union sought certification for employees at one of the respondent's two plants in Metropolitan Toronto.
Initially, the union sought a single-plant unit while the employer argued for a multi-plant unit.
After a representation vote showed strong support for the union at the larger plant, the parties reversed their positions.
The Board applied the Usarco criteria to assess the community of interest between the two plants.
Finding no functional interdependence, separate hiring and supervision, and different products, the Board concluded there was no sound reason to sweep the smaller plant's employees into the bargaining unit.
A certificate was issued for the single plant.
