“Self-sufficiency, with its connotation of economic independence, is a relative concept. It is not achieved simply because a former spouse can meet basic expenses on a particular amount of income; rather, self-sufficiency relates to the ability to support a reasonable standard of living. It is to be assessed in relation to the economic partnership the parties enjoyed and could sustain during cohabitation, and that they can reasonably anticipate after separation. See Linton v. Linton (1990), 1990 CanLII 2597 (ON CA), 1 O.R. (3d) 1, [1990] O.J. No. 2267 (C.A.), at pp. 27-28 O.R. Thus, a determination of self-sufficiency requires consideration of the parties’ present and potential incomes, their standard of living during marriage, the efficacy of any suggested steps to increase a party’s means, the parties’ likely post-separation circumstances (including the impact of equalization [See Note 13 below] of their property), the duration of their cohabitation and any other relevant factors.
Self-sufficiency is often more attainable in short-term marriages, particularly ones without children, where the lower- income spouse has not become entrenched in a particular lifestyle, or compromised career aspirations. In such circumstances, the lower-income spouse is expected either to have the tools to become financially independent or to adjust his or her standard of living.
In contrast, in most long-term marriages, particularly in traditional long-term ones, the parties’ merger of economic lifestyles creates a joint standard of living that the lower- income spouse cannot hope to replicate, but upon which he or she has become dependent. In such circumstances, the spousal support analysis typically will not give priority to self- sufficiency because it is an objective that simply cannot be attained. See Linton at p. 27 O.R.”
