The representative plaintiffs in a class action alleging a price-fixing conspiracy for packaged bread sought to amend their pleadings and the Certification Order to add Maple Leaf Foods Inc. as a certified defendant.

The original Certification Order had refused certification against Maple Leaf on the basis that the pleadings disclosed no cause of action against it, and this decision was not appealed.

The Court of Appeal upheld the motion judge's dismissal of the motion, finding that the original refusal to certify was a final order that gave rise to res judicata.

The court held that the Class Proceedings Act does not permit relitigation of matters finally decided, and the motion judge did not err in refusing to exercise his limited discretion to bypass res judicata.

The Plaintiffs brought a motion to reconsider a previous certification ruling that dismissed the action against Maple Leaf Foods Inc. (MLF) in a class action alleging price-fixing.

The Plaintiffs sought to certify the action against MLF, presenting new evidence including a Second Information to Obtain (ITO), MLF's annual reports, Canada Bread's Agreed Statement of Facts (ASF) from a criminal proceeding, and emails from Canada Bread's files.

MLF opposed the motion and brought cross-motions to exclude the new evidence and strike the Plaintiffs' amended claims.

The court dismissed the Plaintiffs' motion, finding that the 'new evidence' was either not new, inadmissible hearsay, or did not substantively alter the lack of a viable cause of action against MLF.

The court emphasized the principle of finality in litigation, stating that a certification dismissal for lack of cause of action is a final order and cannot be revisited without meeting a strict test for new evidence (Sagaz test), which was not met here.

The court also granted MLF's motion to exclude the evidence and strike the amended statements of claim against MLF.
