Efficiency and cost effectiveness are key considerations under the new carriage test in s. 13.1 of the Class Proceedings Act, according to a recent decision of Justice Perell in Bonnick v. Simply Group. Justice Perell’s decision makes it clear that the new provision is a significant departure from the common law test on carriage, and emphasizes factors of efficiency, proportionality and the cost-effectiveness of the proceeding as key determinants for carriage going forward.
