Since the Supreme Court of Canada’s 2013 trilogy of decisions in Pro-Sys, Sun-Rype and Infineon, and its 2019 decision in Godfrey, plaintiffs have had considerable success certifying private antitrust/competition class actions in Canada.  It is thus noteworthy that a number of recent decisions suggest a growing judicial willingness to limit or dismiss proposed competition class actions at the certification stage or before certification through preliminary motions.
