OLRB cannot use s. 133 of the Labour Relations Act to extend mandatory collective agreement timelines for referring a grievance to arbitration.
The Union appealed a Divisional Court decision that quashed an Ontario Labour Relations Board (OLRB) decision.
The OLRB vice-chair had ruled that he had jurisdiction under s. 133 of the Labour Relations Act, 1995 to extend the time for referring a grievance to arbitration, despite the mandatory 14-day time limit in the collective agreement having expired.
The Divisional Court found this decision unreasonable, holding that once the time limit expired, the grievance was deemed settled and there was nothing left to refer to arbitration.
The Court of Appeal dismissed the Union's appeal, agreeing with the Divisional Court that the OLRB's interpretation of s. 133 was unreasonable and that the OLRB cannot ignore the express mandatory timelines in a collective agreement.
