The much-awaited Petrowest decision from the Supreme Court of Canada is likely to provide further clarity on the "limited circumstances" in which the single-proceeding model in insolvencies will override an arbitration agreement. Petrowest may also provide clarity on the scope of the doctrine of separability, which is a cornerstone principle in both domestic and international arbitration law. Separability — whether a party can disclaim, or separate, an arbitration clause without disclaiming the entire contract — is a fundamental question, and Petrowest may extend the Supreme Court of Canada's discussion of the separability doctrine in Uber Technologies Inc. v. Heller. 16 The Supreme Court's decision could influence whether Canada is perceived as an arbitration-friendly jurisdiction and may impact how counsel and parties globally view Canada as a potential seat for international arbitration.
