Key points
How labour arbitration works.
In Ontario, every collective agreement must provide for final and binding settlement by arbitration, without stoppage of work, of all differences about its interpretation, application, administration or alleged violation. If an agreement lacks that provision, the Act deems one into it.

An arbitration decision binds the parties and the employees affected by it. If a party does not comply, the decision can be filed in the Superior Court of Justice and enforced as a judgment of that court.

Ontario arbitrators can compel the production of documents, summon witnesses, accept evidence whether or not a court would admit it, and interpret and apply human rights and other employment-related statutes.

Where an employee was disciplined for cause and the collective agreement sets no specific penalty, an Ontario arbitrator may substitute a penalty that seems just and reasonable in all the circumstances.

With the parties' consent, an Ontario arbitrator may mediate at any stage, and keeps the power to decide if mediation does not resolve the matter.

In federally regulated workplaces, the Canada Labour Code requires every collective agreement to provide for final settlement without stoppage of work, by arbitration or otherwise, and an award can be filed in the Federal Court and enforced as its judgment.

Questions
Frequently asked questions
Is an arbitrator's decision final?
Yes. Grievance arbitration is a final and binding process. Under Ontario's Labour Relations Act, 1995, the decision binds the parties and the employees affected by it.
What if the parties cannot agree on an arbitrator?
In Ontario, if the parties fail to appoint an arbitrator, either party may ask the Minister to make an appointment under section 48. That appointment is at the Minister's discretion.
Can an arbitrator also mediate?
Yes, with the parties' consent. In Ontario, an arbitrator may mediate at any stage and keeps the power to decide if mediation fails. Under the Canada Labour Code, a federal arbitrator may likewise help resolve the difference without losing the power to continue the arbitration.
