Does a plaintiff have capacity to bear the costs of a defendant in a class action?

However, Rosenberg J.A.'s reference to Cullity J.'s judgment in Mortson v. Ontario Municipal Employees Retirement Board, supra, suggests that Rosenberg J.A. meant that insofar as the aspect of having a capacity to fund the litigation was relevant, a representative plaintiff in a proposed class proceeding should be treated no better and no worse that a plaintiff in a normal action, where the capacity to bear a costs award arises in the context of a motion for security for costs. A corollary to this conclusion is that the defendant to a class proceeding should be in no better and no worse a position than it would be in a normal litigation. I, therefore, conclude that the representative plaintiff's ability to pay costs to an opponent should be determined in the context of a motion for security for costs and not as an aspect of the certification motion.
