577. The court cannot refuse to authorize a class action on the sole grounds that the class members are part of a multi-jurisdictional class action already under way outside Québec.
If asked to decline jurisdiction, to stay an application for authorization to institute a class action or to stay a class action, the court is required to have regard for the protection of the rights and interests of Québec residents.
If a multi-jurisdictional class action has been instituted outside Québec, the court, in order to protect the rights and interests of class members resident in Québec, may disallow the discontinuance of an application for authorization, or authorize another plaintiff or representative plaintiff to institute a class action involving the same subject matter and the same class if it is convinced that the class members’ interests would thus be better served.
