When a spouse earns far more than $350,000 a year, many people assume the Spousal Support Advisory Guidelines stop being useful. That is not quite right. The Guidelines still matter, but the analysis changes.
For higher income cases, the SSAGs do not produce a single automatic answer. Instead, they provide a framework, and courts are expected to take a more individualized, fact-specific approach. The federal SSAG User’s Guide says that in high income cases it is wise to calculate support using the $350,000 ceiling as a minimum, the payor’s full actual income as a maximum, and sometimes one or more intermediate income figures in between.
Why the $350,000 ceiling is not a hard stop
The SSAG ceiling does not mean support is capped once income passes $350,000. It means the court must move away from a purely formulaic result and assess the facts more closely. The federal guidance expressly recommends alternative calculations at different income levels to help “triangulate” an appropriate outcome in high income cases.
That is why lawyers often calculate:
- the low end based on $350,000
- the high end based on the payor’s actual income
- one or more middle figures to test what is fair
This is not guesswork. It is the accepted method for dealing with incomes above the SSAG ceiling.
The Halliwell approach: intermediate incomes can matter
One Ontario Court of Appeal decision often discussed in this area is Halliwell v. Halliwell. There, the Court of Appeal held that the trial judge made an error by using the full $1 million income figure without properly accounting for the effect of equalization and the recipient’s investment income. The court instead applied the SSAGs using an intermediate income of $675,000, described as the midpoint between the $350,000 ceiling and the full imputed income.
That matters because Halliwell shows that courts may use a middle figure where full income would overstate the proper support result, but using only the $350,000 ceiling would understate it. The point is not that midpoint income must always be used. The point is that intermediate incomes are a legitimate tool in the right case.
High income cases with child support are harder
The analysis becomes more complicated when child support is also in play.
Under the SSAG guidance, child support and spousal support do not always use the same income figure. The federal User’s Guide notes that when the payor’s income exceeds $350,000, courts will usually order child support based on the full table income, sometimes up to $1 million, while using a lower income figure for spousal support.
That is a big practical point. In higher income cases:
- child support may be based on full actual income
- spousal support may be based on a lower or intermediate income
- the court may separately assess what is fair for each obligation
This is why support calculations in high income parenting cases can become highly technical.
Do not forget section 7 expenses
Another trap in high income cases is failing to properly account for special or extraordinary expenses under section 7 of the Child Support Guidelines.
Where there are children, section 7 costs can be substantial. If those expenses are not properly factored into the overall analysis, the support result can become distorted. The high income spousal support discussion is never just about salary. It is about the full financial structure of the post-separation family. This is also consistent with the SSAG emphasis on real-world outcomes rather than rigid formulas.
The real takeaway for Ontario families
The lesson from the SSAG high-end range is simple: once income climbs above $350,000, support does not become automatic, but it does become more nuanced.
Courts may:
- start at the $350,000 ceiling
- test the full income result
- use an intermediate income to reach a fair amount
- treat child support and spousal support differently
- pay close attention to section 7 expenses and the broader financial picture
That is why high income support cases are rarely plug-and-play. They require judgment, context, and a careful review of the numbers. The formula still matters, but it no longer decides the case by itself.
Final word
If you are dealing with spousal support in a higher income Ontario case, the fight is usually not about whether the Guidelines apply at all. It is about how they should be used.
That can make a massive difference in outcome.
