Key takeaways
  • The Spousal Support Advisory Guidelines are advisory only: they are not legislated and their use is voluntary.
  • The guidelines do not decide whether you are entitled to support; entitlement is decided under the Family Law Act or Divorce Act first.
  • One formula applies when there are no dependent children and a different one applies when the recipient has primary care of children and child support is paid.

If you are separating or already paying or receiving spousal support, you have probably heard people mention the guidelines or the SSAG. They are often used as a starting point for talks about how much support should be paid and for how long.

This article explains what the guidelines are, what status they have in British Columbia, and how the two main formulas work in general terms. It is general information, and your own numbers and circumstances can change the result.

This article covers the law of British Columbia.

What the guidelines are

The Spousal Support Advisory Guidelines, often called the SSAG, were published by the Department of Justice Canada. They are a set of formulas that produce a suggested range for the amount and the length of spousal support.

They are not a statute. They have not been legislated and their use is voluntary. The BC government describes them as not law, but says most lawyers and judges use them to help set the amount.

Do BC courts have to follow them?

No. Because the guidelines are advisory only, a court is not bound to apply them. In practice they carry a lot of weight, since most lawyers and judges use them.

The guidelines also come second. Entitlement to support must be established under the Family Law Act or the Divorce Act before the formulas apply. In BC, the Family Law Act sets the objectives of spousal support and says the amount and duration must reflect each spouse's condition, means, needs and other circumstances.

Neither the Family Law Act nor the Divorce Act sets a minimum length of marriage for spousal support, and the length of cohabitation is one factor in amount and duration.

The without child support formula

This formula is used where there are no dependent children. It is based on the difference between the spouses' gross incomes.

ItemGeneral rule
Amount1.5% to 2% of the gross income difference for each year of marriage, up to a maximum of 50%
Long marriagesFor marriages of 25 years or longer, the range is 37.5% to 50%
Upper limitCapped at the level that would equalize the spouses' net incomes
Duration0.5 to 1 year of support for each year of marriage

The length of the relationship runs from the start of cohabitation, including cohabitation before marriage, to the date of separation, not the date of divorce.

Duration can be indefinite, meaning not time-limited, if the marriage is 20 years or longer, or if it lasts at least 5 years and the years of marriage plus the recipient's age at separation total 65 or more. This is often called the rule of 65. Indefinite orders remain subject to review and variation.

The with child support formula

This formula is used where the recipient has primary care of dependent children and child support is paid. It works from net incomes, and the lower-income spouse receives 40% to 46% of the spouses' combined net disposable income.

The calculation requires software. Duration limits are described as soft and depend on the length of the marriage and the children's ages, and initial orders are generally indefinite. The BC government notes that a lawyer usually does the calculation, and that MySupportCalculator.ca gives a rough estimate.

Exceptions and what to do next

Formula results are ranges, not guaranteed entitlements. Short marriages without children usually produce very limited awards, sometimes none, even with a large income gap, and small amounts are often converted to a lump sum or a very short transitional award. There are also exceptions to the formula for compensatory, interim, basic needs or hardship, and disability situations.

Frequently asked questions

Are the Spousal Support Advisory Guidelines law in BC?

No. They are advisory, have not been legislated, and their use is voluntary. The BC government says they are not law, but most lawyers and judges use them to help set the amount.

Do the guidelines decide whether I get spousal support?

No. Entitlement must be established under the Family Law Act or the Divorce Act before the formulas apply.

Does the length of the relationship matter?

Yes. Under the guidelines, length of the relationship affects both the amount and the duration. The statutes set no minimum length of marriage, but length of cohabitation is one factor.

Is the result of the formula guaranteed?

No. The formulas produce ranges, and exceptions can apply, especially in short marriages. A lawyer can tell you how they may apply to your situation.
