Law360 Canada ( May 23, 2025, 2:44 PM EDT) -- Appeal by appellant Attorney General of Canada from the order of the motion judge that certified the action as a class proceeding. The respondent, a veteran of the Canadian Armed Forces, suffered severe injuries from an improvised explosive device in Afghanistan in 2009. His injuries included the amputation of his right leg, traumatic brain injury, hearing loss and other significant physical damages. The respondent claimed that Veterans Affairs Canada (“VAC”) mishandled his applications for disability benefits, resulting in psychological harm and aggravated physical injuries due to delays and errors in processing his claims and sought to advance the case as a class action on behalf of other veterans similarly affected. The motion judge certified the class action conditionally, requiring the class definition to be amended to the satisfaction of the parties and the court. The appellant appealed the motion judge’s decision to certify the action as a class proceeding, arguing that the class definition was unworkable and that the negligence claim was invalid. Further, the appellant contended that the motion judge erred in finding a valid cause of action in negligence and that the class definition did not meet the requirements for certification under the Class Proceedings Act, 1992....
