The union representing maintenance workers grieved against a paper company for contracting out manufacture of signs to an outside contractor. The arbitrator upheld the grievance based on an argument that the union made during the rebuttal stage of the hearing. The company claimed it was unfairly denied the right to rebut the union’s rebuttal but the Court of Appeal let the original arbitration ruling stand. The company had a chance to address the argument before the rebuttal, said the court [Bowater Mersey Paper Co. v. Communications, Energy & Paperworkers Union of Canada, Local 141,  N.S.J. No. 127, March 18, 2010].
