“Irrespective of whether the proposed support is periodic or lump sum, it is incumbent upon counsel to provide the judge deciding the matter with submissions concerning the basis for awarding and the method of calculating the proposed support, together with a range of possible outcomes. Further, it is highly desirable that a judge making a lump sum award provide a clear explanation of both the basis for exercising the discretion to award lump sum support and the rationale for arriving at a particular figure. Clear presentations by counsel and explanations by trial judges will make such an award more transparent and enhance the appearance of justice. Over time, this approach will undoubtedly foster greater consistency and predictability in the result.
As part of this approach, where an award of lump sum spousal support is made as a substitute for an award of periodic support, it is preferable that, with the benefit of submissions from counsel, the judge consider whether the amount awarded is [in keeping with the Spousal Support Advisory Guidelines (Ottawa: Department of Justice Canada, 2008) (the “Guidelines”). If it is not, some reasons should be provided for why the Guidelines do not provide an appropriate result: Fisher v. Fisher (2008), 2008 ONCA 11 CanLII, 88 O.R. (3d) 241, [2008] O.J.
