On October 22, 2021, the Supreme Court of Canada released its decision in Northern Regional Health Authority v Horrocks, 2021 SCC 42 [Horrocks]. The issue before the Court was whether a labour arbitrator had exclusive jurisdiction over an alleged infringement of The Human Rights Code in Manitoba (the “Code”), which arose from a unionized workplace. Justice Brown, writing for a majority of the Court, held that while the Code vests broad jurisdiction in the Manitoba Human Rights Commission (the “Commission”) to receive, investigate and refer human rights complaints to adjudication where appropriate, nothing in the Code displaced the exclusive jurisdiction of a labour arbitrator to resolve all disputes arising from the collective agreement under The Labour Relations Act (the “LRA”).
Linda Horrocks was a unionized employee of the appellant, Northern Regional Health Authority (“NRHA”). She had previously been suspended for attending work under the influence of alcohol. Ms. Horrocks then entered into a “last chance agreement” with the NRHA, which required her to abstain from alcohol and participate in addiction treatment. She was subsequently terminated by the NRHA for an alleged breach of those terms.
Ms. Horrocks’ union did not grieve her termination. Instead, Ms. Horrocks filed a complaint with the Commission alleging that the NRHA failed to reasonably accommodate her disability. The matter was referred to the Chief Adjudicator for determination, but the NRHA objected, arguing that the dispute fell within the exclusive jurisdiction of a labour arbitrator under its collective agreement.
Ultimately, the Supreme Court agreed.
Following its previous decision in Weber v Ontario Hydro,  2 SCR 929, the Court set out a two-part test to be applied when resolving jurisdictional issues between labour arbitrators and competing statutory tribunals, such as human rights adjudicators:
Applying the two-part test to Ms. Horrocks’ complaint, the Court noted that Manitoba’s legislature had included a mandatory dispute resolution clause in s 78 of the LRA, which required every collective agreement to include a mechanism to resolve all differences about the meaning, application or violation of the agreement. In this case, the NRHA and Ms. Horrocks’ union had selected labour arbitration as that mandatory mechanism.
Meanwhile, under the Code, the Court found that the Commission had broad jurisdiction to receive and investigate human rights complaints and may refer those complaints to adjudication. No provision of the Code, however, expressly displaced the exclusive jurisdiction of an arbitrator under s 78 of the LRA. The Court concluded, therefore, that a labour arbitrator had exclusive jurisdiction over all disputes arising from the meaning, application or violation of the collective agreement.
Turning to the second stage of the test, the Court found that the essential character of Ms. Horrocks’ complaint arose squarely from the NRHA’s exercise of its rights under, or potential violation of, the collective agreement. Factually, the essence of the complaint was that the NRHA had exercised its management rights under the collective agreement in a manner that was inconsistent with its obligation, both under the agreement and statute, to comply with the Code. As such, the dispute fell within the exclusive jurisdiction of a labour arbitrator and was never properly within the Chief Adjudicator’s jurisdiction.
Finally, it is also noteworthy that the Court in Horrocks declined to revisit one aspect of its recent standard of review decision, Canada (Minister of Citizenship and Immigration) v Vavilov, 2019 SCC 65 [Vavilov]. The Court confirmed that because the issue on judicial review involved the jurisdictional lines between two statutory tribunals, the proper standard of review was correctness. In doing so, the Court expressly rejected the argument that the Vavilov framework should be modified to increase deference to an administrative decision-maker when it is determining the essential character of the dispute before it.
Following Horrocks, parties to collective agreements should expect that workplace disputes will ordinarily fall within the exclusive jurisdiction of labour arbitrators. While each case will turn on the particular legislative scheme at issue and the factual nature of the dispute in question, it will likely be rare that issues arising in the course of employment will fall outside of the jurisdiction of labour arbitrators given the mandatory dispute resolution clauses that are contained in labour relations legislation across Canada. Further, should a legislature wish to confer jurisdiction on another statutory decision-maker to hear a dispute arising from a unionized workplace, clear and express language will be required to create concurrent jurisdiction.
