This calculation apparently produced what the husband’s
counsel submitted was a Guidelines range for increased spousal
support of between $1,397 and $1,863 per month. In the end,
the husband’s counsel acknowledged that his client could pay
increased spousal support at the high end of this range. He
submitted that to the extent this left any shortfall in the wife’s
budget, she should be able to contribute that amount.
(2) Section 17(7) of the Divorce Act
 Section 17(7) of the Divorce Act addresses the factors to be
considered on a change motion relating to spousal support:
17(7) A variation order varying a spousal support order should
(a) recognize any economic advantages or disadvantages to the for-
mer spouses arising from the marriage or its breakdown;
(b) apportion between the former spouses any financial consequences
arising from the care of any child of the marriage over and above
any obligation for the support of any child of the marriage;
(c) relieve any economic hardship of the former spouses arising from
the breakdown of the marriage; and
(d) in so far as practicable, promote the economic self-sufficiency of
each former spouse within a reasonable period of time.
(3) The Guidelines
 The final version of the Guidelines was published in July
2008. As described in their executive summary, they were
developed to bring more certainty and predictability to the
determination of spousal support under the federal Divorce Act.
The Guidelines have not been formally enacted by any level
of government. They are, however, a very valuable tool for
assessing a reasonable range of spousal support and should not
be departed from lightly.
(4) The motion judge’s reasons
 The motion judge divided his analysis of the spousal support issue into four sections.
 In the first section, the motion judge analyzed whether the
husband’s early retirement brought about a material change in
circumstances that would allow for a variation of the existing
support order and the separation agreement. He concluded that
under the separation agreement, as confirmed by the consent
court orders, the following matters could amount to a material
change in circumstances and that all had occurred: the husband’s
early retirement; an increase in the husband’s income; and
a change in the number of children entitled to child support.
