Does a judge have any authority to restrict the use of the term "securities" in the context of a class action?

The judgment authorizing the class action (Chandler v. Volkswagen Aktiengesellschaft, 2018 QCCS 2270) was decided by the same judge. In that judgment, Châtelain, J. used the term “securities” in a sense that was not limited to the four types of equity shares in question (see, e.g., paras [58], and especially [105]). She interpreted the motion for authorization as referring to four categories of equity shares by way of example and not by way of a limitative list. There are other references in the authorization judgment that confirm this view.[2]
