“Matrimonial negotiations occur in a unique environment and therefore unconscionability in the matrimonial context is not equivalent to unconscionability in a commercial context (Rick v. Brandsema, 2009 SCC 10 (CanLII), [2009] 1 S.C.R. 295, at para. 43 [Brandsema]). The question to be asked is whether there were “any circumstances of oppression, pressure, or other vulnerabilities, and if one party’s exploitation of such vulnerabilities during the negotiation process resulted in a separation agreement that deviated substantially from the legislation” (ibid, at para. 44).
Examples of inequality in bargaining may include one party being intellectually weaker by reason of a disease of the mind, economically weaker or situationally weaker. Vulnerability may also arise due to a special relationship of trust and confidence (see Norberg v. Wynrib, 1992 CanLII 65 (SCC), [1992] 2 S.C.R. 226, at para. 33). However, the “mere presence of vulnerabilities will not, in and of itself, justify the court’s intervention. The degree of professional assistance received by the parties will often overcome any systemic imbalances between the parties” (Miglin v. Miglin, 2003 SCC 24 (CanLII), [2003] 1 S.C.R. 303, at para. 82, [Miglin]).
In Rosen v. Rosen (1994), 1994 CanLII 2769 (ON CA), 3 R.F.L. (4th) 267 at para. 12 (Ont. C.A.), the Ontario Court of Appeal states the question to be answered in determining unconscionability is whether there was inequality between the parties, or a preying of one upon the other, that placed an onus on the stronger party to act with scrupulous care for the welfare and interests of the vulnerable. At para. 13 the Court notes it is: “not the ability of one party to make a better bargain that counts. Seldom are contracting parties equal. It is the taking advantage of that ability to prey upon the other party that produces the unconscionability”.”
