Life changes after separation — and so do financial realities. Whether you are the person paying or the person receiving spousal support, a support order that made sense at the time of your divorce may no longer reflect what either of you earns, needs, or expects. Ontario law provides a legal pathway to revisit support: a process called a motion to change.

If you are wondering whether your changing spousal support order in Ontario can be adjusted, the short answer is yes — but only if you can show the right threshold has been crossed. Acting on a handshake or simply stopping payments without court approval can expose a payor to enforcement action and arrears. Understanding the rules before you move will save you time, money, and conflict.

This article explains what counts as a material change, how the motion process works, the difference between changing a court order versus a domestic contract, and the most common life events that trigger a successful variation or termination.

What Is a "Material Change in Circumstances"?

Both the Divorce Act (for support tied to a divorce proceeding) and the Family Law Act (for unmarried or common-law partners, or where parties proceeded under provincial law) require a material change in circumstances before a court will revisit a spousal support order.

A material change is one that:

The court looks at the totality of the change. A single small shift — a modest raise, a short period of illness — will rarely qualify on its own. A permanent, substantial shift in the financial picture of either spouse is far more likely to meet the threshold.

Common Triggers

Job loss or reduced income (payor): If the payor loses their job, takes a lower-paying role, or faces a significant income reduction, they may apply to reduce or suspend support. Courts will scrutinize whether the change is voluntary (for example, a career switch) or involuntary (a layoff), and whether the payor is making reasonable efforts to find equivalent work.

Increased income (payor): A substantial raise, new business income, or an inheritance can give the recipient grounds to seek an increase in support. The Spousal Support Advisory Guidelines (SSAG) are a strong analytical tool courts use — higher payor income often translates to higher support under the SSAG formulas, even after the original order.

Income increase (recipient): If the recipient has significantly improved their financial position — a new job, career advancement, or an inheritance — the payor can argue the compensatory or needs rationale for support has diminished. Courts balance this against whether the support was time-limited or indefinite.

Retirement: Genuine retirement by the payor — particularly at the normal retirement age for their profession (as of writing — verify) — is frequently found to be a material change. Courts examine whether the retirement is legitimate or a strategy to reduce obligations.

Repartnering or cohabitation: In Ontario, if the recipient spouse begins cohabiting in a marriage-like relationship, the Divorce Act and the Family Law Act both provide mechanisms to revisit or terminate support. The precise rules and thresholds differ between statutes. Cohabitation may reduce the recipient's need, but courts also consider whether support was partly compensatory — compensation for career sacrifices during the marriage — rather than purely need-based.

Expiry of a time-limited order: If the original order was set to end at a specific date or milestone (for example, when the children complete school), that built-in end date functions automatically. No motion is required; payment simply stops.

Court Orders vs. Domestic Contracts (Minutes of Settlement)

How you vary support depends on the form of your original agreement:

Court Orders

A final order from the Superior Court of Justice or the Ontario Court of Justice can be varied by filing a motion to change under the applicable rules. You file the motion in the court that made the original order (or in your local court if circumstances require). You must establish the material change, and the court applies the law afresh — it is not bound by the original analysis, though prior factors remain relevant.

Minutes of Settlement and Domestic Contracts

Minutes of settlement signed at mediation or a separation agreement signed as a domestic contract under the Family Law Act are not court orders. Varying them is more complex:

Payors who simply stop paying based on their own assessment of the situation — without a court order or written agreement amendment — risk enforcement through the Family Responsibility Office (FRO), which can suspend driver's licences, garnish wages, and register liens against property.

How to Bring a Motion to Change

  1. Gather financial disclosure. Both parties exchange updated Statements of Income, net-worth statements, and supporting documents (tax returns, pay stubs, benefits statements).
  2. Attempt negotiation or mediation first. Courts expect reasonable efforts to resolve the issue outside the courtroom; mediation can also produce a consent order that formalizes any agreed change.
  3. File the motion to change. In the Ontario courts, this is done using a prescribed court form. The motion may be preceded by a case conference.
  4. Attend the hearing. Both parties present evidence of the alleged change, current finances, and the applicable legal framework including the SSAG range and the rationale of the original order.
  5. Enforcement stays active until a new order is in place. Do not unilaterally reduce payments while the motion is pending unless a temporary order expressly permits it.

Reducing vs. Ending Support Entirely

A court can:

Indefinite support is not the same as permanent support. However, long marriages with significant income disparity — or where one spouse made substantial career sacrifices — carry a stronger presumption that support continues for many years. The SSAG duration ranges provide useful benchmarks (as of writing — verify current guidelines). Courts weigh the length of the marriage, the roles each spouse played, and the realistic prospects of the recipient achieving financial self-sufficiency.

Frequently asked questions

Can I stop paying spousal support if my ex is living with someone new?

Not automatically. You must bring a motion to change and demonstrate that the new relationship constitutes a marriage-like cohabitation and that this materially changes the recipient's need or the rationale for the original support. The court has discretion; it does not terminate support as a matter of course simply because a new partner is in the picture.

What happens if my ex refuses to disclose their income?

You can bring a motion compelling financial disclosure. Courts take failure to disclose seriously and can draw adverse inferences — assuming a higher income than admitted — against a party who withholds documents. Persistent non-disclosure can also result in cost awards against the non-disclosing party.

Does voluntary early retirement count as a material change?

It depends. Courts distinguish between a good-faith retirement consistent with the payor's age, health, and profession, versus a strategic retirement designed to reduce obligations. Retirement at a younger age or in unusual circumstances receives closer scrutiny, and a court may impute an income to a payor who retires early without compelling reason.

Can a separation agreement prevent me from ever going back to court?

Some agreements include "final and binding" language or a release of variation rights. Courts can still revisit support in extreme circumstances — particularly where strict enforcement would cause unconscionable hardship — but such releases are generally given significant weight. Have a lawyer review any release clause before signing.
