The appellant appealed a decision of the Ontario Court of Appeal which quashed an arbitration board's award.
The Court of Appeal held that the failure to give notice of the arbitration to two unions that could be significantly affected by the award constituted a denial of natural justice.
The Supreme Court of Canada agreed with this conclusion and dismissed the appeal, noting that fairness and natural justice require notice to those significantly affected.
The Court also clarified that an arbitrator cannot be granted jurisdiction over a jurisdictional dispute without statutory authority or the consent of all parties.
