The plaintiff brought a proposed class action against the Toronto Police Services Board for mass detentions and arrests during the 2010 G20 summit.
After the motion judge dismissed the certification motion, the plaintiff narrowed her claims on appeal.
The Divisional Court allowed the appeal and certified two separate class actions.
The Court of Appeal dismissed the defendant's appeal, upholding the certification of the location-based subclasses and the detention centre class, finding that the narrowed claims met the certification criteria under the Class Proceedings Act.
The Court of Appeal allowed the plaintiff's cross-appeal on costs, increasing the costs award for the certification motion to $315,000 to reflect the legislative goal of access to justice.
