In Uber v. Heller – a case involving an employment class action subject to an international arbitration agreement – the Supreme Court of Canada decided three issues that threatened to undermine the enforceability of international arbitration agreements in Canada. The Court: (1) read the scope of the Canadian International Commercial Arbitration Acts narrowly; (2) created an exception to the competence-competence principle; and (3) relaxed the test for invalidating arbitration agreements on unconscionability grounds. At the same time, Uber was decided in a highly specific factual context and its ultimate impact on the enforcement of international arbitration agreements was largely left to be determined by lower courts in future cases. This article examines two such cases involving consumer class actions subject to international arbitration agreements. The article analyses the courts’ application of Uber and its effect on their reasoning and on the outcome of these cases. While it is difficult to predict how Uber will unfold in the lower courts over time, the two cases examined in this article suggest that Uber is unlikely to affect the enforcement of most international arbitration agreements in the context of consumer class actions – perhaps the context most akin to that of Uber – let alone in more traditional commercial contexts.
