The applicants brought jurisdictional dispute applications regarding the assignment of work for the fabrication and installation of a monorail at the Bruce Nuclear Generating Station.
The Canadian Union of Public Employees, Local 1000 raised a preliminary constitutional challenge, arguing that labour relations at the nuclear facility fall under federal jurisdiction.
The Board applied the functional test and determined that while the production of nuclear energy and its attendant safety concerns are within federal jurisdiction, the fabrication and installation of the monorail is not integral to the federal undertaking.
Having found it had jurisdiction, the Board directed Ontario Hydro to assign the work to the applicants based on collective agreements and historical practice.
