“In Serra v. Serra, 2009 ONCA 395 (CanLII), 66 R.F.L. (6th) 40, the Court of Appeal has confirmed that the law of costs in family law cases is designed to foster three important costs principles: (1) to indemnify successful litigants for the cost of litigation; (2) to encourage settlements; and (3) to discourage and sanction inappropriate behaviour by litigants: see also, Fong v. Chan (1999), 1999 CanLII 2052 (ON CA), 46 O.R. (3d) 330 (C.A.). In Mattina v. Mattina, 2018 ONCA 867 (CanLII) at para. 10, the Court of Appeal stated that Family Law Rule 2(2) adds a fourth factor: to ensure that cases are dealt with justly.”
