Aviva Insurance Company of Canada brought a motion to set aside its notice of abandonment of appeal, seeking leave to file a new factum or an extension of time for filing a notice of appeal.
The respondent, 8262900 Canada Inc. (CarePartners), brought a cross-motion for directions regarding its cross-appeal.
Aviva had abandoned its appeal after an application judge found partial insurance coverage but did not address apportionment of costs, an issue Aviva intended to pursue in a new application.
CarePartners' subsequent supplementary cross-appeal raised res judicata and issue estoppel, which Aviva's counsel had not anticipated when abandoning the appeal.
The court dismissed Aviva's motion, finding the abandonment was a deliberate strategic decision, not due to inadvertence, mistake, or misapprehension.
The court emphasized the importance of finality in litigation and found Aviva's proposed appeal on apportionment lacked merit as the issue was not raised before the application judge.
CarePartners' cross-motion for directions was granted.
