The Ontario Court of Appeal recently affirmed the decision of the Ontario Superior Court of Justice in Nortel Networks Corporation , [1] that the "interest stops" rule applies in proceedings under the Companies' Creditors Arrangement Act [2] . Specifically, the Court held that the "interest stops" rule applies in liquidating CCAA proceedings, such as Nortel, as parties retain the right to provide for the payment of post-filing interest in a CCAA restructuring plan.
