Compensatory and Non-Compensatory Spousal Support: What Is the Difference?

Before anyone argues about amount, entitlement has to be established. Which basis applies changes how much is paid, for how long, and how easily it can be reduced later.

Spousal support is not automatic. Before anyone argues about how much and for how long, one question has to be answered: is there an entitlement to support at all? Canadian law recognises three bases on which entitlement can be established, and the one that applies shapes everything that follows.

Compensatory support

Compensatory support comes from the Supreme Court of Canada's decision in Moge v. Moge in 1992. The principle is that where the roles taken during a relationship produced an economic advantage for one spouse and an economic disadvantage for the other, support compensates for that imbalance.

What a compensatory claim looks like

• One spouse left the workforce, or reduced to part time, to raise children.
• One spouse relocated for the other's job, repeatedly or at a critical point in their own career.
• One spouse worked to support the other through a degree or professional qualification.
• One spouse worked in the other's business, often unpaid or underpaid, building an asset held in the other's name.
• One spouse absorbed the household and childcare load so the other could build earning capacity without interruption.

Under the Divorce Act, this maps onto the objectives in section 15.2(6): recognising the economic advantages and disadvantages arising from the marriage or its breakdown, and apportioning the financial consequences of child care.

Non-compensatory support

Non-compensatory support comes from Bracklow v. Bracklow, decided by the Supreme Court in 1999. It is based on need, and on the interdependency that a relationship creates. The Court described it as arising from the merger of two lives: when people live together and organise their finances around each other, a mutual obligation can arise that does not simply stop at separation.

What a non-compensatory claim looks like

• Illness or disability that limits a spouse's ability to support themselves.
• Age, where re-entering the workforce at a meaningful income is not realistic.
• A long marriage in which both lived to a standard neither can maintain alone.
• A significant income gap with no realistic path to closing it.

Here the relevant Divorce Act objectives are relieving economic hardship arising from the breakdown, and promoting economic self-sufficiency within a reasonable period where that is practicable.

Contractual support

The third basis is contractual: the parties agreed to it, in a marriage contract, a cohabitation agreement or a separation agreement. An agreement can also attempt to waive support entirely. Such a waiver can be challenged, and the framework for doing so comes from Miglin v. Miglin in 2003, which looks at the circumstances in which the agreement was made and whether it still reflects the parties' original intentions in a substantially changed reality.

Why the distinction matters in practice

1. Entitlement is a gate

If no basis applies, there is no support, regardless of the income difference between the parties. An income gap on its own does not create entitlement.

2. Duration

A strong compensatory claim tends to justify support toward the longer end of the range, and in a long marriage often indefinite support. A modest non-compensatory claim following a shorter relationship is more likely to be time limited and transitional in character.

3. Resistance to reduction

Support grounded in compensation is more durable. It is tied to something that already happened and cannot be undone. Support grounded purely in need is more exposed: if the need changes, the basis for the support changes with it.

4. Self-sufficiency

Self-sufficiency is listed as an objective where practicable, not as a deadline and not as a duty. A recipient does not lose entitlement simply because time has passed. Where the claim is compensatory, the fact that someone has become self-supporting does not erase what the marriage cost them.

5. Variation and review

Which basis underlies an order matters years later, when someone brings a motion to change. A clear record of why support was ordered in the first place is one of the most valuable things a separation agreement or order can contain. Agreements that set an amount without ever stating the basis create arguments later.

Where the Spousal Support Advisory Guidelines fit

The Spousal Support Advisory Guidelines are advisory. They are not legislation and they are not binding. They do not create entitlement, and they assume entitlement has already been established.

Once it has, the Guidelines produce ranges for amount and duration using two formulas: one for cases where child support is also payable, and one for cases where it is not. Where a case falls within those ranges, and whether a case should fall outside them, is informed by which basis of entitlement applies and by the statutory objectives.

Married, unmarried, and which statute applies

In Ontario the route depends on the relationship and the relief sought:

• Married spouses seeking a divorce proceed under the federal Divorce Act.
• Unmarried partners, and married spouses not seeking a divorce, proceed under Ontario's Family Law Act.

The Family Law Act defines spouse for support purposes to include unmarried partners who have cohabited continuously for at least three years, or who are in a relationship of some permanence and have a child together. Its list of support objectives is broader than the federal list and expressly includes relieving financial hardship and recognising a spouse's contributions to the relationship.

What this means for your case

Most real cases are not purely one thing. A long marriage with children and an income gap usually has both a compensatory and a non-compensatory dimension, and the two reinforce each other. The work is in identifying what actually happened during the relationship, documenting it, and framing the claim or the response accordingly, before any number is put on the table.
