Key takeaways
  • The Spousal Support Advisory Guidelines are not law, and above a payor income of $350,000 the formulas are not applied mechanically.
  • Entitlement must be established first; a large income gap alone does not create it.
  • Where the formulas stop being a guide, judges use discretion based on the usual support factors.

If you or your spouse earn a very high income, you may have heard that spousal support formulas stop working at a certain point. That is partly true, and it often causes confusion about what happens next.

This article explains in general terms what the ceiling in the Spousal Support Advisory Guidelines (SSAG) means in Ontario, how support is approached above it, and what to prepare. The results vary a great deal with the facts.

What the SSAG are, and what the ceiling means

The SSAG are not law, but judges often base their spousal support decisions on them. They were designed for the federal Divorce Act, and courts and lawyers also often use them under provincial legislation such as Ontario's Family Law Act.

The formulas do not apply mechanically at the extremes. Above a payor income of $350,000, discretion is used, and incomes below $20,000 and $30,000 require adjustments. The figures are stated in the Guidelines without indexing, and courts may approach them differently, so ask a lawyer how they are treated in your case.

How the formulas work below the line

It helps to see what the formulas do before the ceiling is reached. Without child support, the range is 1.5% to 2% of the difference between the spouses' gross incomes for each year of cohabitation, capped at 50%, and the top of the range cannot exceed the amount that would equalize net incomes. With child support, the range leaves the lower-income recipient with 40% to 46% of the couple's combined Individual Net Disposable Income.

Payor income above $350,000Discretion is used rather than a mechanical result

What courts do above the ceiling

There is no set formula result above the ceiling. Courts return to the general factors: each spouse's condition, means, needs and other circumstances, including how long the spouses cohabited and the roles each played. An order should recognize economic advantages or disadvantages from the marriage or its breakdown, share the financial consequences of caring for children, relieve economic hardship, and promote self-sufficiency so far as practicable.

Entitlement still comes first. It can be compensatory, non-compensatory or contractual, and an income gap on its own does not create it. Where child support is also in play, the court must give child support priority.

Interim support and evidence of income

While an application is pending, the court can make an interim spousal support order. The Guidelines apply to interim orders too, and where income evidence is thin, ranges can be estimated using alternative income figures. Compelling financial circumstances just after separation can justify interim support above or below the range.

High-income cases often involve complex pay, such as bonuses, corporate income or investments. The Guidelines start from the definition of income in the Federal Child Support Guidelines, and section 19 of those Guidelines is often the basis for imputing income. Online tools are limited: Ontario's page notes that the SSAG calculator it links to considers only employment income and simple calculations.

What to do next

A lawyer can explain how a court is likely to treat income above the ceiling in your circumstances and whether a negotiated agreement makes sense.

Frequently asked questions

What happens to the formulas if the payor earns over $350,000?

The formulas do not apply mechanically above a payor income of $350,000, and discretion is used. The court relies on the general support factors, such as means, needs and roles during the relationship.

Does a big income gap automatically mean support?

No. An income gap on its own does not create entitlement, which must be proven or agreed before the formulas apply. Entitlement can be compensatory, non-compensatory or contractual.

Are the SSAG binding on judges?

No. They are not law, though judges often base their decisions on them.

Can support be ordered while the case is ongoing?

Yes. The court can make an interim spousal support order until the application is decided. The Guidelines apply to interim orders as well as final orders.
